This is a unique conference. There is no exhibition in Versailles in the Copywest, but the unknown science and engineer has opened the most affectionate confession. Say goodbye to the dead and solemn in the hotel conference room, the bar burst-style atmosphere, let the seemingly boring Chery Technology Salon is so comfortable.
General Manager of Chery Auto Co., Ltd., Executive Director of the Power System Technology Center
Technology Chery is always left to consumers impression. Chinese consumers have special needs for cars. This is not to be able to meet the European and American Japanese and Korean cars. The power is strong, the fuel consumption is low, the car network is also intelligent to let you put down your phone. Rich master passive safety configuration and spacious and comfortable ride space is their appeal of a good home car. And this is also a problem for Chery, and even the whole Chinese independent brand. 
How to break through the competition of the group, only the technique of innovate can make the brand “top” and embrace the future. Just like the party secretary of the Chery Auto Co., Ltd., Chairman Yin Tong Yue said: “Land” is to continue to deepen the fuel truck technology; it is well known, including 1.6TGDI, Chery has received a total of six engines. ” China Heart “Year Top Ten Engine Awards. Progress and innovation in the technical level are also obvious.
The meaning of “top” is to accelerate the development of “new four”. Especially new energy power assembly, intelligent network, automatic driving and other emerging technologies to make pointers, make China’s automotive industry truly powerful, and let consumers take the surprises and beautiful in technology innovation. 
1.0 era! The above figure is that when we visited Chery Wuhu engine factory, we were put on the engine exhibits on Chery QQ. It is equivalent to the Kaishan’s nasal ancestors in Chery 1.0 in 1997, has been technically developed, and built its own engine factory. This engine is a crystallization developed by Chery and Austrian AVL. The investment of 80 million euros allows Chery to slowly have independent research and development. The explosive models launched in 2004 Chery QQ308 were equipped with this model.
2.0 era! Many years of accumulation and fighting, Chery has always adhering to the principle of independent innovation, and has achieved breakthrough results in key core technologies. The second generation of engines were born in 2009. At that time, the Chery Tiggo SUV, and the Ai Ruizu series, all equipped with this 1.5T turbocharged engine. You have to know that it can meet the national six emission standards in that era, and the thermal efficiency can reach 37.1% of the model. Open our autonomous brand car’s engine cover, printed with Mitsubishi engine, has not returned. 
4.0 era! When it comes to the engine, Chery Motor has a 24-year-old research and development accumulation experience. At the end of the Shanghai Auto Show ended at the end of April this year, the Chery brand released the “Chery 4.0 era”, “the so-called whole domain, that is, provides professionalism, providing professional) Power solution. In order to meet the various travel vehicles that users can encounter.

Look, not only the automobile engine, Chery or even have an aerospace engine R & D capabilities. Diamond DA42, DA40 two fixed-wing aircraft is equipped with this engine.
Nowadays, through three stages of technological innovation, the thermal efficiency of Gasoline engine in Pope has reached 41%, and the thermal efficiency of the hybrid model can reach 45%. The oil rate exceeds 95%. And by visiting Chery’s Power Lab, we see that PHEV based on new hybrid technology will also be fully applied, such as this Tiggo 8 PLUS PHEV model with DHT.
What is DHT? DHT is an abbreviation of hybrid-specific transmission, based on conventional gasoline transmission, relying on the effect of adding electrified components to achieve hybrid power. In Chery’s power laboratories, this is a model of 1: 1. The power unit can reach a thermal efficiency to a 1.5T mixing engine, with a plurality of plug-in hybrid systems composed of a single motor + after single motor. 
The domestic DHT configuration in the Honda I-MMD is two motors. One motor is used to drive the vehicle directly, and the other is specifically to generate electricity in the extension mode. When the energy is recovered, the engine is driven in parallel to accelerate, which does not directly participate in the drive wheel. And Chery’s dual motor is really a double motor driver! By using two medium low-power motors to avoid frequent starting time, low efficiency is low + high energy consumption. And no need for importing high power motors, costs have also been significantly improved.
The most interesting thing is that there are three files! And this Songpeng DHT transmission comes with nine working modes and 11
gear
. This is very rare in China! This also means that the DHT transmission allows the engine direct drive to operate in high-efficiency intervals, reducing fuel consumption at high speed cruise, and can be able to have a higher two-motor matching on the original efficiency., Relying on the adjustment of the gear, further improve the efficiency of the motor. The TSD double-axis drive is given to the driver’s driving experience. Its NEDC operating electric drive average efficiency is greater than 90%, the maximum transmission efficiency is greater than 97.6%, the pure electric total sound pressure level is only 75 decibels, the design life is 1.5 times the industry level.
Chery’s first model of this technology is the PHEV version of Tiggo 8 Plus. The left front wheelbood of the car has joined the PHEV charging jack. The upper edge of the entire side window is also covered by blue decorative strips, indicating the new energy car identity.
The taillight lamp cover of the car is still a smoked design, and the bilateral width exhaust gas is highlighting the strength of the silver. In order not to destroy the overall beauty of the car, only the blue PHEV identification indicates the identity of its plug-in mixing.
Such a PHEV model, 10 kilometers accelerated less than 5s, 100 kilometers of loss of electricity fuel consumption is still less than 5L, pure electricity can exceed 100km, full oil full power state The overtime work condition can exceed 1000km. The Tiggo 8 PLUS PHEV version of this still launched did not list 
did the balance between fuel consumption and power.
In addition to the new energy field, Chery is also a tree in traditional fuel power. The previous 1.6TGDI engine has won the honorary title of China’s heart year ten engine. The Qirui Pipe 2.0TGDI engine equipped on Tiggo 8, gathered a new technique of intelligent management system, ultra-low friction design, variable displacement oil pump, etc., independently designed and developed. 
has a maximum power of 187kW, and a peak torque of 390 nm. For SUVs of 1.9-ton, relying on the second-generation I-HEC intelligent combustion system, it has lowered its 100-kilometer comprehensive fuel consumption to 8L, and truly fuel consumption and power generation.
Not only the power assembly, including the use of the car network, automatic driving, vehicle design and manufacturing, has always adhered to the autonomous innovation of Chery Automobile, has achieved breakthrough results in key core technology. As of now, Chery Group has applied for more than 21,000 patents, authorizes more than 13,000 patents, ranking in front of the Chinese auto industry.
Technical Chery Motor has experienced a multi-year technology accumulation, has won the favor of 9.2 million users worldwide. In 2021, the sales company in the global auto market is leading all the way. In January-April, the Qirui Group has a total sales of 282,000 units, an increase of 91.6 percentage. Among them, 21,000 vehicles exported in April, the year-on-year increase of 312.5 percent, and then create a new high this year. Chery cars that have been promoted by the product power and brand power, and 53,680 sales were achieved in April, a year-on-year increase of 117.2 percentage.
Chery Brand In the past 24 years, Gu Chun Mountain, a technical veteranstructor, who has worked in Chery for 22 years. He dedicated his youth and blood to Chery’s engine factory. Because he believes in Chery Brand Yin, “Enterprises must have to grow up, must seize the” cow nose “.” Be sure to attack the power technology, spending money to buy, the death technology, Chery must master the technology. ” “From 1.0-4.0, the four generations of engine development, the hand-held science and engineer attacked a technical difficulty. Now, Chery can pride , CheryEngine technology has been on the same horizontal line with the advanced technology station of international large-brand car companies.
