In the early years, domestic independent brands did not have research and development capabilities, and they still relied on joint ventures with foreign companies in automobile production. However, with the continuous self-improvement of domestic independent brands in the subsequent development, they finally have the ability of independent research and development, and they also have considerable strength in engine research and development.
Chang 'an Blue Whale
Changan blue whale engine ranks first. More than 200 engineers from different countries have studied the technology of this engine. The blue whale engine was built by these engineers in the R&D center for four years. During these four years, 1.5T and 2.0T engines were built respectively.
Blue Whale Engine has more than 100 patented technologies, and won the title of Top Ten Engines in China for three consecutive years. The maximum thermal efficiency of this engine can reach 40%, and the blue whale 1.4T high-pressure direct injection technology can output a peak value of 260 Nm. The peak output of 2 1 1 is only 250 Nm.
Chery GDI
Among domestic engines, Changan Blue Whale is Chery 1.6T? GDI engine, which is the first engine in China that dares to promise 1 10,000 km 10 year warranty. This engine adopts intelligent tumble combustion control system, with thermal efficiency as high as 37. 1%, which can also reduce fuel consumption and enhance power performance.
Chery GDI adopts cylinder head integrated exhaust manifold and variable displacement oil pump, which has sufficient power, certain fuel economy and relatively low engine noise. The engine has 1250 rpm turbine intervention, and the peak torque can reach 290 Nm, which is better than Mercedes-Benz 1.6T engine.
Geely 1.5T Hybrid Power System
Then, the third place is the Geely family's 1.5T hybrid system. From a technical point of view, the Geely family's 1.5T hybrid system can compete with the brand-new Audi A6 that has already appeared overseas. This engine is a light hybrid engine, replacing the 48V all-in-one machine.
And the effect it can play is that it has outstanding performance in fuel saving and energy saving. The technology of this engine can save fuel by about 8%- 15%. Moreover, it is also the leading technology in China in terms of mask intake mechanism and low inertia turbocharging technology.
Great wall 2.0T
Following the Geely family is the usual 2.0T engine, ranking fourth. The advantage of Great Wall Motor lies in its independent research and development, which is relatively leading in the domestic market at present, which is also the main reason why it can occupy a place in the technical scope of the domestic market.
Its 2.0T turbocharged engine is equipped with advanced technologies such as electronically controlled dual-channel exhaust gas turbocharger, electronically controlled gasoline in-cylinder direct injection and double overhead camshaft. The maximum torque of this engine can reach 385 Nm, and its maximum power is 165 kW.
This kind of power data performance has stronger power performance than Volkswagen EA888 engine and BMW B48A20C engine with the same displacement. Compared with joint-venture vehicles and foreign-funded vehicles with the same displacement, the engine of Great Wall will have better power performance.
Hongqi 2.0T
Hongqi Automobile is a big boss brand in China and an outstanding representative of domestic independent brands. The 5th ranked 2.0T engine of Hongqi Automobile, code-named CA4GC, has a power value of 224 horsepower and 340 Nm. This engine is mounted on the Hongqi Hs5 model, with an acceleration of 8.2 seconds per 100 kilometers.
The comprehensive fuel consumption per 100 kilometers given by the Ministry of Industry and Information Technology is 7.9L This engine is not only outstanding among domestic brands, but also among many joint venture brands. Cooperating with other engines is Aisin's 6AT gearbox. If the gearbox can be changed to 8AT, the strength is enough to surpass most joint venture brands.
