Disassembly of Ford 1.5T engine with Focus and other main cars.

  [car home Engine Disassembly] Engine energy saving and emission reduction is the general trend. In order to comply with the trend, major automobile manufacturers around the world have introduced small-displacement turbocharged engines to win market opportunities. American manufacturers, who have always been regarded as keen on large-displacement engines, have also actively carried out research and development of small-displacement turbocharged engines in recent years. Ford is one of them, and its latest 1.5T EcoBoost engine (hereinafter referred to as "Ford 1.5T engine") is the first to be installed on the 2013 Changan Ford Mondeo. After the launch of Changan Ford Mondeo, the 1.5T engine was also mounted on the main models of Changan Ford such as Maverick, Focus and Taurus. What we are going to dismantle today is this Ford 1.5T small-displacement turbocharged in-cylinder direct injection engine. What kind of characteristics does it have? Let’s find out by disassembling it.

Low Ford 1.5T engine of those things.

  European emission regulations have always been very strict, forcing manufacturers to improve their engine design to reduce emissions. Therefore, Ford European technical team has more mature experience in developing low-emission engines. The 1.5T engine to be dismantled today is a small-displacement turbocharged direct injection engine designed by Ford European technical team.

  This Ford 1.5T engine is a global engine product, which means that its emission level can meet the emission targets of all countries in the world. When the engine is put into a specific market, it must be adjusted domestically to meet the local use environment. China has a vast territory, a large latitude span, and a large altitude difference and temperature difference. The engine engineer in charge of domestic adjustment must go to cold yakeshi, hot Hainan and the Qinghai-Tibet Plateau with thin air to adjust the parameters of the engine management system accordingly, so as to ensure that the engine can work efficiently and stably anywhere in China.

  The 1.6T engine is equipped with an external air-cooled intercooler, and the exhaust manifold is not integrated in the cylinder head. The 1.5T engine is more mainstream in configuration, adopting water-cooled intercooler integrated in the intake manifold and integrating the exhaust manifold into the cylinder head. This Ford 1.5T engine can be regarded as an improved model of 1.6T, adopting more mainstream technologies.

Comparison Table of Parameters of Ford’s Two Small Displacement EcoBoost Engines (Parameters from Changan Ford Maverick) project Ford 1.5T engine Ford 1.6T engine displacement 1499mL 1596mL Maximum power 181 HP /6000rpm 177 HP /5700rpm Peak torque 240 N m /2000-4500rpm 240 N m /1750-4500rpm Cylinder diameter x stroke 79mm X 76.45mm 79mm X 81.4mm

  The 1.5T engine reduces the displacement by 0.1L, but the power is increasing (the maximum power is increased by 4 HP, and the peak torque value remains unchanged). In China, the consumption tax on vehicles with 1.5T engines is 3%, while the consumption tax on vehicles with 1.6T engines is 5%. Without the 2% tax saved by 0.1L displacement, the Ford model with 1.5T engine has higher flexibility in pricing, which is conducive to improving the competitiveness of the model. It can be seen that Ford has already considered China’s tax policy when planning the engine product. (Vehicle consumption tax is included in the vehicle price and paid by the vehicle enterprise to the state)

  Ford didn’t follow the Volkswagen who pushed the dual clutch. The 1.5T engine was matched with a 6-speed automatic gearbox, which is what I like to see. After all, with more products, consumers have more choices. Moreover, the performance and transmission efficiency of the mainstream 6-speed automatic gearbox are not low, and it has a good performance in shifting smoothness and durability, which is a recommended configuration.

   In the same class with Ford 1.5T engine, there are not a few models with 1.4T, 1.5T and 1.6T engines. General 1.5T engine and Ford 1.5T engine are in direct competition because of their close displacement, while Volkswagen 1.4T engine and Citroen 1.6T engine are also two powerful competitors.

Parameter comparison table of three mainstream 1.5T engines name Ford 1.5T engine General 1.5T engine
(LFV) Volkswagen 1.4T engine
(EA211) Citroen 1.6T engine

  Ford 1.5T engine is more focused on power output. Compared with other manufacturers’ 1.4T, 1.5T and 1.6T engines, the power output of this engine has obvious advantages. In terms of torque output, the torque output of Ford 1.5T engine meets the standard of mainstream 1.5T engine.

  The 1.5T engine mounted on Changan Ford is produced by Changan Ford Motor Co., Ltd.. The engine we disassembled this time is a teaching prototype, and some parts are slightly different from the mass production model. Before it’s too late, let’s completely disassemble this engine!

● Overhead direct injection system

  Ford 1.5T engine adopts overhead in-cylinder direct injection system, and the high-pressure gasoline nozzle is located at the top of the combustion chamber. Unlike the side nozzle, the overhead nozzle will not spray gasoline on the cylinder wall, thus avoiding the "wet wall phenomenon". Wet wall phenomenon will lead to engine oil dilution, fuel economy decline and emission increase.

● Turbocharging system

  The turbocharger used in Ford’s 1.5T engine is provided by Borg Warner, and the maximum speed can reach 150,000 rpm. The maximum pressurization pressure of the turbocharging system of the engine can reach 1.5Bar. Like Volkswagen 1.4TSI engine and general 1.4T engine, this engine adopts an integrated exhaust manifold which can improve the thermal efficiency of the engine.

  Compared with the turbocharging system, the overhead direct injection system of Ford 1.5T engine has more "gold content". Geometric modeling of piston crown, angle of oil jet from nozzle, position of spark plug, organization of intake and exhaust airflow and later verification of combustion system all need a lot of time and rich experience.

● Variable intake and exhaust valve timing system

  The advantage of variable intake and exhaust valve timing technology is that the combustion exhaust gas can be removed from the cylinder by fresh air through the overlapping angle of intake and exhaust valves with a large angle to improve combustion efficiency and power output. The application of large-angle overlap angle of intake and exhaust valves in manifold injection engine may lead to the waste of fuel and increase fuel consumption. However, the in-cylinder direct injection engine does not have the above concerns, and can control the fuel injection timing and not inject fuel during scavenging, so that the gas used for scavenging is fresh compressed air without gasoline, and the fuel consumption is not increased while the combustion exhaust gas is removed. This is also one of the reasons why the mainstream direct injection engine is fuel-efficient now.

● Valve drive structure with simple structure

  Ford 1.5T engine does not adopt roller rocker valve drive structure with complicated structure but lower friction coefficient, but adopts valve top cylinder drive structure with relatively simple structure. However, through the optimization design of camshaft, this valve drive system effectively meets the corresponding design objectives and realizes the balance between cost and benefit.

  The use of timing belt is beneficial to reduce engine noise. The engine adopts a simple top cylinder valve drive structure, but some designs are adopted on the cam and valve seat ring to reduce friction and improve durability. The adoption of variable intake and exhaust valve timing system enables the engine to flexibly control the overlap angle of intake and exhaust valves, which makes the engine exhaust more smoothly under high load, and at the same time, the fresh air entering from the intake valve can completely "clean" the exhaust gas in the cylinder, which improves the efficiency of the engine.

● Reinforcing structure of cylinder block/cylinder head

  Some structural designs are adopted on Ford 1.5T engine to strengthen the strength of cylinder block. The improvement of the overall strength of the engine not only improves the service life of the engine, but also has certain benefits for the NVH characteristics of the engine.

● Unique coolant tank, cylinder net pattern and oil nozzle.

  In addition to the above-mentioned cylinder reinforcement structure, the cylinder of Ford 1.5T engine has more unique designs, and the shallow groove between the cylinders is one of them.

● Integrated intercooler

   The first step of engine operation is to inhale air from the environment, and for turbocharged engines, the air from the environment will be turbocharged first, and then it will be sent to the cylinder after the air pressure is increased. The blades on the turbine compressor do work on the air, which will increase the air temperature. In order to further improve the density of compressed air, increase the amount of oxygen entering the cylinder and increase the output power of the engine, there will be a device called "intercooler" in the intake system of turbocharged engine, and its function is to cool the pressurized air. According to statistics, under the same air-fuel ratio, the engine power can be increased by 3% ~ 5% for every 10 degrees Celsius drop in the temperature of pressurized air.

  A large number of reinforcing structures are adopted on the cylinder head and cylinder block of Ford 1.5T engine to enhance the overall strength of the engine. However, the coolant tank between the cylinders and the crankshaft bearing cover bracket are very special, which are rare in other engines of the same class.

● Vacuum pressure storage tank for start-stop system.

  We saw a box as shown above the intake manifold of Ford 1.5T engine. This box is actually a vacuum pressure storage tank, which is connected with a vacuum pump to store the negative pressure required by the brake booster pump. Then why do other models rarely see this device?

● Mechanical variable displacement oil pump

  Ford 1.5T engine uses a mechanical variable displacement oil pump, which realizes two-stage variable displacement through internal mechanical structure. At low speed, the displacement of oil pump is kept at a low level to reduce power loss; At the middle and high speed, the displacement of the oil pump reaches the maximum, providing sufficient lubrication for each friction pair of the engine.

● Breaking connecting rod and casting crankshaft.

  Like the engines of many mainstream joint ventures that we have dismantled, the Ford 1.5T engine uses a high-cost expansion-breaking connecting rod. The crankshaft is made of cast crankshaft, and in order to realize light weight, only four balance weights are designed.

Cyrus bought AITO Wenjie trademark for 2.5 billion yuan! Huawei responded quickly.

K figure 601127_0

  After the trademarks of "Enjoy the World" and "Smart World" were transferred to BAIC and Chery respectively, the trademark of "Ask the World" was also followed up.

  Announcement on the evening of July 2,Automobile, a holding subsidiary, intends to acquire 919 registered or pending series of text and graphic trademarks and 44 related design patents held by Huawei and its related parties, with a total purchase price of 2.5 billion yuan.

  It is said that the transfer does not affect the cooperation between the two parties.Huawei also responded to the reporter on this matter. "Huawei will transfer a series of trademarks such as the world of inquiry to Cyrus, and will continue to support Cyrus to build and sell the world of inquiry."

  Does not affect the cooperation of intelligent car selection.

  Celestial announcement shows that the board of directors of the company deliberated and passed the Proposal on Purchasing Assets, and its subsidiary Celestial Automobile intends to acquire the registered or pending trademarks held by Huawei.. Including 919 registered or pending written and graphic trademarks held by Huawei, and 44 related design patents, the total purchase price is 2.5 billion yuan.

  The asset appraisal report shows that 740 trademark rights have been authorized, and the remaining trademark rights are being applied for, and the trademark registration certificate has not yet been obtained. The appearance patent is being applied for and has not yet obtained a patent certificate.

  Regarding this acquisition, Cyrus said that the transfer of the subject matter of the agreement will not affect the cooperative business between the two parties, and the two parties will further deepen the cooperative relationship.

  Huawei also responded to the reporter: "Huawei will transfer a series of trademarks such as asking the world to Cyrus, and at the same time, Huawei will continue to support Cyrus to build and sell the world." Huawei said that it has always insisted on not building cars, but using intelligent networked car technology to continue to help car companies build and sell good cars.

  According to analysts, the cooperation mode and consumer experience between Huawei and Cyrus are not affected, and Huawei’s attitude and HarmonyOS Zhixing plan remain unchanged. The source said that after the trademark transfer, the boundary between Huawei’s HarmonyOS Zhixing and Zhixuan models became clearer, and Huawei further indicated that it would not build cars.

  "The brand influence of Wenjie series may be more than 2.5 billion yuan. At present, Wenjie M9 has broken 100,000 vehicles, which is one of the models with the highest sales volume of more than 500,000 yuan." The above-mentioned people continued to say, "HarmonyOS Zhixing has always been a cooperation model in which Huawei has been deeply involved in definition, design, R&D and sales, and the cooperation with other smart partners will not be affected."

  Cyrus has repeatedly shot.

  Since the net profit of returning to the mother turned positive in the first quarter of this year, Cyrus has made many moves.

  In June this year, Sailis announced that its subsidiary Sailis Automobile intends to buy back 55% equity of Sailis Electric held by Jingyun Chuangfu and Saixin Fund according to the agreement, and the corresponding purchase price is about 1.254 billion yuan.

  Prior to this, Celestial Electric was 45% owned by Celestial Automobile, while Jingyun Chuangfu and Saixin Fund held the remaining 40% and 15%. Jingyun Chuangfu is 56.25% owned by CCB Trust, and the platform owned by Chongqing State-owned Assets holds the remaining shares. The background of Chongqing SASAC is also behind Saixin Fund.

  As of the end of March this year, the net assets of Celestial Electric were 785 million yuan, and the net assets corresponding to its 55% equity were about 431 million yuan.Based on this calculation, the consideration for the acquisition of 55% equity of Cyrus Electric this time is 190.95% higher than the net assets of this part of the equity.

  Previously, the state-owned assets took a stake in order to "send charcoal in the snow" for Cyrus in trouble. Sailis repurchased as scheduled, which was also interpreted by the market as its financial pressure has eased.

  Moreover, just after the profit turned positive, Cyrus also announced a change in accounting estimation, that is, the amortization period of intangible assets-non-patented technology was adjusted from 8 years to 5 years.

  It is reported that this change in accounting estimates is expected to increase the amortization of intangible assets of Cyrus in 2024 by about 1.026 billion yuan and reduce the net profit attributable to the mother by about 426 million yuan. Some investors even bluntly said, "It shows that Sailis is not short of profits this year".

  As of July 2, the market value of Cyrus reached 135.9 billion yuan.

  The trademarks of "Zhijie" and "Xiangjie" have been transferred.

  In fact, Huawei had transferred the trademarks of "Zhijie" and "Enjoy the World" one after another before Celeste took the trademark of "Wenjie" into its pocket.

  According to Sky Eye, at the end of May, Huawei transferred its registered trademark of "Enjoy the World" to Beijing.Automobile co., ltd. The trademark was applied by Huawei in May last year and registered in November.

  At the beginning of June, Huawei transferred two registered "Zhijie" trademarks of transportation tools to Chery. The above trademarks were applied by Huawei in October 2013 and September 2019, and were registered in April 2015 and April 2020 respectively.

  According to an EIA report of BAIC, Xiangjie S9 was mass-produced in June 2024. During its life cycle (5 years), the total sales volume is expected to reach 480,000 vehicles, that is, from 2024 to 2028, the annual sales volume will be 60,000 vehicles, 120,000 vehicles, 120,000 vehicles, 96,000 vehicles and 84,000 vehicles respectively.

  According to the latest sales data, HarmonyOS Zhixing delivered 46,100 vehicles in June, up 50.9% from the previous month, and delivered 194,200 vehicles in the first half of the year. Starting from August this year, HarmonyOS Zhixing will launch the "three worlds" (asking world, intellectual world and enjoying world), and enjoying world S9 will also become the most expensive car product under HarmonyOS Zhixing.

If you want to fly solo when your wings are hard, aqara, a green rice without Xiaomi, may break her wings.

Edit | Paul Yu Pin

Produced by Chaoqi. com "See the column"

Many enterprises have racked their brains to be listed in the big enterprise ecosystem, but aqara, a green rice in the Xiaomi ecosystem, insists on breaking the circle and actively decoupling the rice chain. At present, many enterprises want to join the giant’s ecological circle for their long-term development, but green rice aqara, who is in the Xiaomi ecological circle, chooses to jump out of the comfort zone and gradually go Xiaomi.

At present, smart home is on the eve of the outbreak, and its market scale is growing rapidly. According to IDC data, it is estimated that by 2024, the market scale of smart home in China is expected to exceed 500 billion yuan, and the market shipment of smart home equipment will increase to about 500 million units, with a compound annual growth rate of 23%.

And because of its large population, China will be the most potential smart home market in the world. Faced with such a huge market, many giants have entered the market one after another, and different enterprises have established their own ecological circles. According to the restrictions of relevant agreements, it is difficult for various hardware devices joining different ecological circles to be compatible.

Therefore, in order to develop rapidly, many small enterprises compete to join the ecological circle dominated by large factories. As one of the players in the first echelon of smart home in China, Xiaomi Ecosphere has rapidly grown into a unicorn in the industry because of catching a ride with Xiaomi. However, with the help of green rice aqara, which is growing rapidly in the rice chain, it chooses to decouple the millet ecosystem. Can it live better in the future?

Rice chain blessing, green rice aqara gradually grows.

The growth of green rice aqara is inseparable from the blessing of Xiaomi, and it is precisely because of the blessing of rice chain that green rice aqara gradually occupies a place in the field of smart home.

It is understood that the predecessor of Green Rice aqara is Shenzhen Lutuo Technology, and its main business is not smart home, but an enterprise that focuses on the research and development and application of wireless building control systems for environmental energy collection.

In 2014, due to the shortage of funds, Xiaomi, Shunwei and world-renowned financial investment institutions invested in green rice to tide over the difficulties, and in that year, green rice was included in the Xiaomi ecological circle, that is, at that time, Green Extension was officially renamed as Green Rice, and it was also responsible for the research and development of smart home products of Xiaomi.

Green rice has also entered a process of rapid growth due to its back to the millet industry chain. Green rice aqara’s products cover almost all aspects of Mijia smart home.

In 2015, Green Rice also released the first Xiaomi smart home package product. As an enterprise of Xiaomi ecological chain, aqara products are closely linked with Mijia smart brand, which not only makes Mijia smart products have a wider application range, but also promotes the development of Green Rice aqara.

According to the data, Green Rice aqara’s products and equipment have spread to more than 9,000 cities in 192 countries around the world, serving more than 2 million smart home users, but Xiaomi has contributed a lot.

With the help of Xiaomi ecological circle, green rice aqara has survived the most difficult period of the industry. With the progress of science and technology, the market scale of smart home industry is growing, and the industry is also in the stage of imminent outbreak.

In order to occupy the market share, Green Rice aqara has carried out a big reform, changing the sales model from distribution agent to offline channel joining, which has opened a new river of domestic smart home offline service provider system.

It is precisely because of the existence of aqara Home Experience Store that Green Rice Aqara has increased the interaction and immersive experience between consumers and products, and successfully integrated the 2C and 2B solutions of the Internet of Things. The effect of this reform is very obvious. The old users of the experience store have become the second largest customer acquisition channel for green rice Aqara, and the proportion of referral orders has gradually increased from 15% to 22.4%.

Later, with the help of Xiaomi Ecosphere, green rice aqara became more and more famous. With the help of Xiaomi’s huge ecological chain, Green Rice Aqara already has service providers and offline stores covering most cities nationwide, and its products have gradually increased to more than 30 categories and more than 500 SKUs with the penetration rate of Xiaomi products.

However, in order to gain a bigger stage and higher income, in recent years, green rice aqara has gradually decoupled from the millet ecosystem. Can this really make it better?

Inconsistent ideas, green rice aqara decoupling rice chain

In recent years, with the further expansion of the scale and the increasingly fierce competition in the domestic smart home industry, green rice aqara began to be not limited to the millet ecosystem. In 2021, green rice aqara joined the matter agreement, officially jumped out of the Xiaomi ecological circle, was in line with international standards, and served international smart home manufacturers such as Apple and Google.

As a new smart home protocol based on open source ecology, matter protocol breaks the separation between platforms and the differences in development paths, making smart home products compatible between different manufacturers and brands, which sounds like it is of great benefit to the smart home hardware vendors, but the most fatal flaw is that this protocol was initiated by foreign manufacturers, and there is still some uncertainty about whether it can be used in China in the future.

For the development of the enterprise, it is understandable to join this agreement, but the following practices of green rice aqara to actively decouple the millet ecosystem are incomprehensible.

Since 2020, many new products of Green Rice aqara have only supported mainstream platforms such as APPleHomekit, Green Rice App, AmazonAlexa and Google Assistant, but they have not supported Mijia at first. For example, the network management M2 has caused discussion on the Internet, and some people even questioned whether Green Rice aqara should give up the big tree of Xiaomi.

Why does aqara, a green rice that can be measured by Xiaomi, begin to gradually decouple rice circles? This has to start from the pricing concept, technical layer agreement and development space.

Judging from the pricing concept, the reason why Xiaomi can be popular all over the country in a short time is nothing more than excellent quality and affordable price. As a high-end smart home product owned by Green Rice, aqara focuses on the high-end market, which has a serious conflict with Xiaomi’s cost-effective play.

More importantly, Xiaomi also has related products that can be used in the smart home market, which virtually competes with green rice aqara.

As the leader of Xiaomi’s ecological circle, Xiaomi has strong bargaining power, and the profit of its industrial chain hardware business does not even exceed 5%, which makes Xiaomi’s competitiveness more obvious and makes green rice aqara, who is also in the smart home industry, very uncomfortable.

It is understood that at present, the price of millet switches is mostly between 59-69 yuan, while that of green rice aqara switches is between 89-600 yuan. This price difference makes green rice, which is the main high-end market, unbearable.

More importantly, Xiaomi switch and green rice aqara switch are all produced by enterprises in the industrial chain, and their quality is not significantly different.

In addition to the differences in pricing concepts, technical conflicts are also a major factor. Xiaomi, as an integrator of ecological circle, has designed many products. In order to lower the threshold of users, it adopts Bluetooth mesh protocol, while Green Rice, as a single producer of smart home, uses zigbee protocol.

In short, Mijia no longer produces zigbee products, and all products of Green Rice need to be adjusted and retested, which leads to the differences between Green Rice and Xiaomi.

However, as the helm of the ecological circle, Xiaomi’s move is understandable in order to better complete the threshold of the Internet of Everything. If the green rice is adjusted accordingly, the Xiaomi ecological circle will grow rapidly with the arrival of the Internet of Everything in the future.

Technical differences may have a corresponding impetus, but it is probably the current market space problem that directly makes green rice aqara start to decouple from rice circles.

Recently, due to all-encompassing, Xiaomi Ecosphere did not focus its resources on smart homes in a short period of time, which led to the rapid growth of green rice in the rice circle. At present, many Internet manufacturers and home appliance manufacturers in China are in their own smart home ecosystem. The torn ecosystem not only hinders the growth of smart home market, but also affects consumers’ sensory experience.

This makes it difficult for green rice aqara, which has joined the Xiaomi ecological circle, to integrate into other smart home circles in China. Not only that, with the increase of the penetration rate of foreign smart home markets, the time for foreign markets to increase their volume is earlier than domestic ones, which is also the reason for the active decoupling of green rice aqara.

However, can short-term gains really make green rice grow faster? I’m afraid not. As one of the best ecological circles in China, Xiaomi Ecosphere has extraordinary growth potential. Therefore, the active decoupling of green rice aqara may not make it better.

Jump out of the millet circle, can green rice aqara be better?

For the development of the enterprise, it is understandable that green rice aqara jumped out of the millet ecosystem. However, can aqara, a green rice out of Xiaomi’s comfort zone, really create a better world?

Look at the previous Xiaomi ecological chain first to know. In the past, many enterprises that grew rapidly with Xiaomi’s resources, investment, channels and other resources began to grow independently after their business gradually improved, and some even competed directly with Xiaomi.

Green rice is not a case. Before that, there were four Xiaomi eco-chain enterprises, including Huami, Yunmi, Roborock and No.9, which were gradually decoupled from the deep binding of Xiaomi. At present, the effect of these enterprises to millet is average.

Green rice aqara joined the matter agreement this time. Although this agreement can be supported by mainstream smart home platforms such as AppleHomekit, AmazonAlexa and Google Assistant, it is uncertain whether this agreement can become the domestic mainstream under the background of domestic substitution.

More importantly, domestic smart homes have become more and more competitive after precipitation. Without Xiaomi’s blessing in the future, it will be more difficult for green rice aqara to compete with big factories.

As one of the players in the first echelon of smart home in China, Xiaomi Ecosphere has rapidly grown into a unicorn in the industry because of catching a ride with Xiaomi. However, with the help of green rice aqara, which is growing rapidly in the rice chain, it is too short-sighted to choose to actively decouple the millet ecosystem.

Moreover, in the face of different enterprises have established their own ecological circles, it is difficult to be compatible between various hardware devices joining different ecological circles. Green rice aqara joined the matter agreement this time. Although this agreement can be supported by mainstream smart home platforms such as AppleHomekit, AmazonAlexa and Google Assistant, it is uncertain whether this agreement can become the domestic mainstream under the background of domestic substitution and big data security.

At the same time, domestic smart homes have become more and more competitive after precipitation. Without Xiaomi’s blessing in the future, the competition between green rice aqara and domestic manufacturers will be more difficult.

Four-wheel drive Land Rover (imported)-Range Rover

Four-wheel drive structure: basically the same.

Land Rover Land Rover Range Rover Sport Edition 2014 3.0 V6 SC HSE Dynamic

    As we all know, both Range Rover Sport Edition and Range Rover are equipped with full-time intelligent four-wheel drive system and powerful second-generation all-terrain feedback system. Users only need to choose the corresponding driving mode and control the throttle and direction, and the next difficulties and obstacles will be fully handed over to the vehicle itself to overcome. It’s like a fool’s camera. Even if you don’t know how to take pictures, you can still take wonderful pictures. However, do you know what kind of complicated four-wheel drive structure is hidden under this seemingly stupid operation knob?

Home of the car

"The Range Rover and Range Rover Sport Edition of this test drive all adopt this four-wheel drive structure."

    First of all, let’s look at the Range Rover Sport Edition. It can be equipped with two full-time four-wheel drive systems. The central differential with strong off-road capability is a multi-plate clutch structure with low gear. By default, the system distributes the torque evenly in the ratio of 50: 50. According to the change of the combination of multiple clutches, the power distribution of the front and rear axles can be 100% respectively, and the electronic traction control system will also play an auxiliary role. Low gear ensures excellent off-road ability, and can provide 2.93:1 driving force at low gear.

Home of the car

"Range Rover Sport Edition can also be equipped with a four-wheel drive system with single-speed transfer case and +Torsen central differential structure."

    The weak four-wheel drive system adopts the structure of Torsen central differential, and there is no low gear. The mass of this system is 18kg lighter than that of the previous system, and the ratio of front and rear torque distribution is 42: 58 by default. The setting slightly biased towards the rear drive aims to improve its driving pleasure. At the same time, in order to ensure off-road performance, according to the different road conditions and grip, Torsen differential can adjust the maximum distribution ratio of front and rear wheels to 62% and 78% respectively. Theoretically, this system is weaker than the first one in four-wheel drive performance.

    The Range Rover adopts the first four-wheel drive system, and the two cars we tested this time also use this four-wheel drive system. It is worth mentioning that the above is only the middle part of the whole four-wheel drive system. In fact, in order to further optimize the traction and stability under extreme road conditions, consumers can also choose models with dynamic active rear axle limited slip differential (including Range Rover and Range Rover Sport Edition). The rear axle differential lock will form a powerful four-wheel drive system together with the first four-wheel drive system mentioned above.

CVT uses a ball instead of a steel belt? Alternative stepless speed change technology

  [Original by Aika Automotive Technology Channel]

  CVT continuously variable gearbox has the advantages of simple structure, small volume, light weight, smoothness and fuel saving, and is very common in small displacement vehicles. For the structure of CVT, many fans are familiar with it. Generally speaking, the core of CVT is conical wheel and steel belt. The improvement of CVT performance in recent years is due to the progress of steel belt structure and material. But what if I told you that CVT continuously variable gearbox can be used without conical wheel and steel belt?

Alternative stepless speed change technology without steel belt

  Maybe you have to say, "CVT doesn’t use steel belt, so use a ball?"

  Congratulations on your correct answer, just use the ball.

  CVT continuously variable gearbox was born as early as 19th century. In the course of more than 100 years’ development, there have been many kinds of CVT with different structures, which can be mainly divided into two schools. One is the familiar cone-belt/steel belt structure, and the other is the ball as the core variable speed component.

  How does the sphere realize the change of transmission ratio? Under the condition that the rotation axis of the sphere is fixed, the distance that different points on the sphere move in one revolution is different. By changing the angle of the rotating shaft of the ball, the speed difference can be formed between the power input end and the output end in contact with the ball, thus changing the transmission ratio.

  Editor’s comment:CVT continuously variable gearbox with ball as transmission element has been around for a long time, but it has not been applied to automobiles due to various problems. Dana planetary gearbox has solved these problems and its performance is worth looking forward to. At present, Dana has been working with two large vehicle companies to apply this technology to production models. Can it shake the monopoly position of conical wheel-steel belt structure in CVT continuously variable transmission field? Let’s wait and see.
