Top Ten Domestic Engine Ranking List

1. At the beginning of this century, BYD and Chery were the top two independent brand car companies in sales. Moreover, BYD is also quite successful in the field of fuel powertrain. The first domestic turbocharged engine and the first domestic dual-clutch gearbox are all launched by BYD.

2. The engines of the Spring Breeze brand can only be said to be of good quality, but the engines produced by his family can only be used for those cars that require large displacement.

3. Geely Automobile 4T gasoline engine Geely's latest 4T engine is equipped on many 100,000-level models such as Geely Vision and Dihao GL/GS. Its maximum horsepower reaches 133Ps (98kW),The peak torque is 215Nm, and this output parameter is no longer inferior to the joint venture brand engine with the same displacement.

4. FAW-Hongqi 5T gasoline engine equipped with model: Hongqi H Pentium T77 Pro The engine has a maximum power of 124kW and a maximum torque of 258Nm. It adopts 15:1 ultra-high compression ratio, Miller cycle, intelligent thermal management, electronically controlled piston cooling nozzle and variable displacement oil. Pumps and other nine cutting-edge technologies have a thermal efficiency of up to 306%.

What are the characteristics of the engine of the latest civil airsenger?

Compared with the CFM56-3 engine configured on the traditional 737, its thrust is increased by 11%, its noise is much lower than the third-level noise standard, and it also has the characteristics of low fuel consumption and low maintenance costs.

Nowadays, civil airliners generally use turbofan engines. In terms of its working principle, the turbofan engine belongs to a kind of turbine (the rotation of the fluid impact impeller generates power); at the same time, in terms of its working principle, the turbofan engine belongs to a kind of jet engine (ejecting high-speed fluid work).

The characteristics of domestic routes are close and the actual number of passengers is small. ( Except for the Spring Festival Travel Festival) There is no best plane, only the best aircraft. Take the c919 as an example, it is equivalent to the earlier version of the Boeing 737 or Airbus a320, and the range is different from that of the latest 737 or 320.

The characteristic of the combined engine is that the range of working speed is usually much wider than that of ordinary engines, which can achieve better fuel utilization efficiency.
