Recently, the 2019 World New Energy Vehicle Conference (WNEVC) was held in Boao, Hainan. The Chery Powertrain Technology Center exhibited two hybrid products at the conference: a high thermal efficiency 1.6TGDI hybrid engine; a dual-motor multi-mode hybrid dedicated gearbox. Among them, the 1.6TGDI hybrid special engine has been verified by thermodynamic development tests, and its effective thermal efficiency has reached the world’s leading level of 41%. Another exhibited dual-motor multi-mode hybrid special transmission supports 9 working modes including pure electric drive, range-extending mode drive, parallel mode drive, and engine direct drive. The maximum input torque is 510 N·m, which can form 10 A combination of gears can be applied to pure electric, hybrid, range-extended and plug-in hybrid vehicles.

According to reports, once this brand-new powertrain is officially installed on the product, it will accelerate the product from 100 kilometers per hour to less than 5 seconds, the vehicle’s top speed can reach 200km/h, and the pure electric top speed can reach 150km/h.
Chery 1.6TGDI hybrid engine
It is reported that the 1.6TGDI hybrid special engine launched this time has completed the development of a generation of prototypes. It has been verified by thermodynamic development tests that the highest effective thermal efficiency has reached 41%, reaching the world’s leading level. At the same time, this engine also has high thermal efficiency. The characteristics of high lifting power.
What is the concept of 41%? At present, the thermal efficiency of engines on the market is mostly between 30% and 35%. At present, the thermal efficiency of mass-produced cars in the world is the highest, only reaching 41%. It is Toyota’s Dynamic Force Engine 2.5L hybrid engine, which is mainly equipped with Avalon Shuangqing (parameter|picture) and Camry Shuangqing (parameter| picture). In addition to Toyota, the second is the 2.0L engine equipped with the Honda Accord Hybrid (parameter|picture) version, with a thermal efficiency of 40.6%. In addition, there are 1.5L engines of Volkswagen’s EA211 series, and the thermal efficiency can also reach 37.5%. The thermal efficiency of this 1.6TGDI hybrid engine that Chery has just unveiled is 41%, which has reached the world’s advanced level.
Chery dual-motor multi-mode hybrid transmission (DHT)
In addition, the dual-motor multi-mode hybrid transmission (DHT) displayed by Chery this time supports 9 working modes, including pure electric drive, range-extending mode drive, parallel mode drive, and engine direct drive. DHT has three power sources, which can be driven in two different gears respectively. On the one hand, there is no power interruption during the gear shifting process, and on the other hand, it can form 10 combined gears, which makes the vehicle more dynamic and economical.
For a car, the engine and gearbox are the parts that best embody the core technology, and because of their complex structure, these two parts have become a technology that can be developed by a few countries and enterprises. As an independent auto brand that has established a development path of “technology-based enterprise” since its inception, Chery Automobile has become the first domestic auto company to master engine and transmission technology through independent innovation.
So far, Chery has completed the research and development of three generations of engines, and a total of five engines have won the honorary title of “Top Ten Engines in China”. In terms of transmission technology, in addition to the manual transmission, Chery independently developed my country’s first CVT continuously variable transmission with completely independent intellectual property rights, which filled the gap in the domestic high-end automatic transmission. The CVT25 transmission equipped on Chery Arrizo GX was selected as one of the “Top Ten Transmissions in the World” in 2019. Its maximum output torque is 250Nm, and it supports start-stop, electronic shifting, 48V and other extended functions, and can be widely used in traditional and hybrid vehicles. vehicle type.
Continuous breakthroughs in technology have not only enhanced Chery’s product strength, but also promoted Chery’s sales and brand image. In June this year, Chery sold 46,496 vehicles, a month-on-month increase of 8.7%, and a year-on-year increase of 6.8%. Among them, sales of new energy vehicles were 7,253, a month-on-month increase of 74.1%, and a year-on-year increase of 14.2%. From January to June this year, Chery Group sold a total of 325,000 vehicles, including 285,000 self-owned brand models, a year-on-year increase of 8.5%. In the face of the sluggish domestic auto market, it continued to maintain a growth momentum against the trend.
Core technology is the strong foundation of an enterprise, an industry and even a country, and it is the key capability for independent auto brands to compete with international first-line brands. Over the years, Chery Automobile has always adhered to the development route of mastering core technologies through independent innovation. Judging from Chery’s achievements at the 2019 World New Energy Vehicle Conference (WNEVC), Chery Automobile has continuously made breakthroughs in the field of core automotive technology, and is continuing to lead the technological progress of the national auto industry with cutting-edge technology, helping China’s auto industry to move forward. Take it to a new level.
