The ultimate product can achieve an ultra-high performance experience with an acceleration of less than 3 seconds per 100 kilometers.
The picture above shows the Geely 7-speed dual-clutch gearbox.
According to the published data, the DHE 15( 1.5TD) hybrid special engine, which was built by an engineering team of more than 500 people in five years, is the world's first mass-produced supercharged direct injection hybrid special engine. This engine adopts four advanced technologies: high-pressure direct injection, supercharged intercooling, Miller cycle and low-pressure EGR, creating the highest thermal efficiency record of mass-produced hybrid engines in the world-43.32%! It exceeds 4 1% of the highest level of hybrid power in Japan, and the regional coverage rate of high thermal efficiency is close to half. At the same time, it indicates that the thermal efficiency reaches 52.5%, and the torque and power of 1.5TD hybrid special engine are the best in its class.
As another core of Hi X, DHT Pro is the world's first mass-produced 3-speed hybrid transmission, far exceeding the Japanese brand planetary gear transmission and 1 speed transmission. DHT Pro is highly integrated with 6-in 1 such as dual motors, transmission and electronic control, and its weight is only 120kg, but it can reach the amazing maximum output torque of 4920n·m! The torsion mass ratio is 41n m/kg. P 1 generator has no induction switch, and P2 drive motor +3HT ensures that power is on call, so that energy saving and driving control are no longer opposed.
The fuel saving rate is over 40%, and the NEDC fuel consumption is as low as 3.6L/ 100km, leading the world. Based on the world's highest thermal efficiency of 43.32% of mass-produced turbocharged direct injection hybrid engine, DHT? Pro adopts 3-speed ratio, and directly transfers energy to the wheels through direct drive mode, just like direct delivery from the place of origin to the home when shopping, there is no middleman to earn the difference, and zero loss of conversion energy is realized. Lei Shen Qing Hi X is 0.4-0.6L lower than Japanese HEV and saves 9- 12% fuel, so it has a more fuel-efficient car experience than Japanese hybrid cars of the same class.
For the first time, the hybrid system FOTA upgrade was realized, with up to 20 intelligent driving modes, leading the world. Strong self-learning ability, the most intelligent intelligent control system in the same level of power field, the perfect cooperation of engine, transmission and high-voltage battery pack, and as many as 20 intelligent driving modes can provide more timely and intimate dynamic response according to everyone's driving intentions and habits, and truly achieve "integration of people and vehicles".
It can match different A0-C models, adapt to fully hybrid systems such as HEV/PHEV/REEV, and lead the world in scalability to meet everyone's demand for intelligent hybrid. 148 key NVH technology optimization, the best comfort in the world. With 148 power-related optimization, the NVH of engine, gearbox and motor reaches the leading level in the industry, and the sound quality in the car is guaranteed to the greatest extent. Compared with competing products of the same level, the sound pressure in the car equipped with Lei Shen Qing Hi X can be as low as 58 dB at 30km/h, while the best performance of Japanese competing products is about 70 dB. Compared with the two, it is equivalent to the sound environment difference between the office and the shopping center.
Up to now, Geely's power system has been mounted on Geely, Lectra, Proton, European luxury brands and other 100 models, which sell well in more than 60 countries and regions, with global sales exceeding 1000 million units. 20 years' efforts to sharpen a sword, on the road of low-carbon travel and realizing China's global power supply, are Geely's 50 billion yuan power R&D investment, and are the persistence of nearly 10,000 employees and more than 2,000 R&D engineers at home and abroad in quality and innovation.
In terms of power efficiency, the next stage goal of Geely's power thermal efficiency is to break through 57% and maximize the efficiency of the engine. The highest efficiency of transmission reaches 97.5%, which is also the leading level in the world. In the future, we will continue to challenge the physical limit, reaching more than 98%. In terms of drive electrification, the next generation of hybrid products will be launched in 2025, which will increase the fuel saving rate to over 50%. In terms of energy diversification, through more than ten years of technical research, it has solved the world-class technical problems of methanol application in internal combustion engines, and has more than 200 core patents, making Geely the only enterprise in the world with mass-produced methanol vehicle technology. The methanol hybrid vehicle equipped with Ray Shen Qing Hi X hybrid system will also be launched next year. At the same time, the hydrogen engine has also been successfully ignited, with a target thermal efficiency of 45% and zero carbon emissions. ?
Editor's comment: Hi X, the thunder engine, will be carried on "China Star" for the first time. In the next three years, it will provide a variety of power combinations, including strong hybrid, long-life plug-in hybrid and extended-range hybrid. It will be mounted on more than 20 models of Geely, Lectra and other brands, which will usher in a new era of Geely's intelligent hybrid in an all-round way, and will also realize "China Power, Supply the World" for the first time, and truly realize "the latecomers come to the fore". It is hoped that Geely will make continuous efforts to improve its technical capabilities and realize China's intellectual creation at an early date.
