In the early years, domestic independent brands did not have R&D capabilities, and they still relied on joint ventures with foreign companies for automobile production. , but as domestic independent brands continue to strengthen in the subsequent development, we finally have the ability to independently research and develop, and we also have considerable strength in engine research and development.
Chang'an Blue Whale
Chang'an Blue Whale engine ranks first. The technology of this engine was jointly researched by more than 200 engineers, and these more than 200 engineers are from different countries. country, and the Blue Whale engine was built by more than 200 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 has won the title of China's top ten engines for three consecutive years. The maximum thermal efficiency value of this engine can reach 40, and the Blue Whale 1.4T high-pressure direct injection technology can output a peak output of 260 Nm. The peak output of the Volkswagen EA?211 is only 250 Nm.
Chery GDI
Among the domestic engines, Changan Blue Whale’s is the Chery 1.6T GDI engine, which is the first engine in China that dares to promise a ten-year, 1 million-kilometer warranty. This engine uses an intelligent tumble combustion control system, and its thermal efficiency is as high as 37.1, and it can also reduce fuel consumption and enhance power performance.
Chery GDI uses a cylinder head integrated exhaust manifold and a variable displacement oil pump. Its advantages are sufficient power and certain fuel economy. At the same time, its engine The noise is relatively small. The engine has a 1250-rpm turbine intervention, and the peak torque value can reach 290 Nm, which is a victory over Mercedes-Benz's 1.6T engine.
Geely 1.5T hybrid system
Next to it, the 1.5T hybrid system of the Geely family is ranked third. From a technical perspective alone, the Geely family The 1.5T hybrid system is comparable to the new Audi A6 that has been unveiled overseas. This engine forms a mild hybrid by replacing a 48V integrated motor.
The effect it can achieve is its outstanding performance in saving fuel and energy. The technology possessed by this engine can achieve a fuel saving effect of approximately 8-15%. And the Mask air intake mechanism and low-inertia turbocharging technology are also currently leading technologies in the country.
Great Wall 2.0T
Following the Geely family is the Chang 2.0T engine, which ranks fourth. Great Wall Motors' advantage lies in independent research and development, and its independent research and development technology is relatively leading in the current domestic market. This is also the main reason why it can occupy a place within the technical scope of the domestic market.
And its 2.0T turbocharged engine is equipped with advanced technologies such as an electronically controlled dual-channel exhaust gas turbocharger, electronically controlled gasoline in-cylinder direct injection, and dual overhead camshafts. The maximum torque value of this engine can reach 385 Nm, and the maximum power value it has is 165 kilowatts.
This kind of power data performance is more powerful than the Volkswagen EA888 engine and BMW B48A20C engine of the same displacement. Compared with joint venture models and foreign models with the same displacement, Great Wall's engines will have better power performance.
Hongqi 2.0T
Hongqi Motors is a major-level model brand in China and is an outstanding representative of domestic independent brands. Hongqi Motors' 2.0T engine ranks fifth. This 2.0T engine is code-named CA4GC. Its power value can reach 224 horsepower and 340 Nm. This engine is available on the Hongqi Hs5 model and can accelerate from 100 kilometers to 100 kilometers in 8.2 seconds.
The comprehensive fuel consumption data per 100 kilometers given by the Ministry of Industry and Information Technology is 7.9L. This engine’s performance is not only outstanding among domestic brands, but also among many joint venture brands. He is a leader. Cooperating with other engines is a 6AT gearbox from Aisin. If the gearbox can be replaced with an 8AT, it will be powerful enough to surpass most joint venture brands.
