As one of the three core technologies in the automotive industry, the engine has always been the “heart disease†of the development of China’s own-brand vehicles. However, with the successive launch of new engine products such as Great Wall Motors and Brilliance Automotive, the dawn of the automaker's own manufacturing engine is now available.
In early July, China's first electronically controlled high-pressure common-rail diesel engine with independent intellectual property rights - Great Wall TC "Intelligent Fuel-saving King" INTEC officially listed.
It is reported that this product is a cooperation between Great Wall Motor and the European diesel engine design company. It adopts the second-generation common-rail diesel engine technology and is one of the world's leading diesel power sources. The listing of this product means that its own brand diesel engine technology has reached the world's leading level.
On the previous June 26, Brilliance Automotive had just launched its first self-made engine, the 1.8T turbocharged engine. Following the Brilliance, Chery Automobile also announced that the 1.8T turbocharged engine will be officially put into production in August 2007.
Analysts believe that the actions of the Great Wall, Brilliance and Chery show that China's own brand engine development has entered a new stage of climax.
Innovation
Domestic engine performance increased significantly
Different from the domestically produced engines previously listed, this time, regardless of Brilliance's 1.8T or Great Wall Motor’s TC “Intelligent Fuel Economy King†engine, it is relying on joint research with well-known foreign companies and has achieved qualitative and technical performance. leap.
First of all, the new engine has better acceleration performance. Such as the Great Wall TC "Intelligent Fuel Economy" engine, can continuously send 225 Newton meters of maximum torque between 1600 to 2600 revolutions, significantly better than the traditional supercharged diesel engine, to solve the problem of short maximum torque time, power is not stable. The Brilliance 1.8T engine can also be turned in 2000 to 4500 rpm to reach a maximum torque of 235 Nm.
Second, the new engine is quieter. According to reports, the noise of the new Brilliance engine is less than 102dB. Although Great Wall TC is a diesel engine, its noise value is not due to the adoption of the most advanced high pressure common rail fuel direct injection technology.
More than 98dB, more than 16% lower noise than conventional turbocharged diesel engine, fundamentally solves the problems of large noise and poor comfort of the diesel engine. At high speed, the engine is almost the same as the gasoline engine. It is also called the “king of silenceâ€.
Third, the new engine is more environmentally friendly and fuel-efficient. According to reports, the Great Wall TC “Intelligent Fuel Saver†engine uses ECU computers to control the fuel distribution, injection time, injection pressure, and injection rate flexibly and accurately. Compared with conventional turbocharged diesel engines, the combustion efficiency is 8%, and the fuel consumption per 100 km is higher than that of conventional pressurization. The diesel engine has been reduced by more than 20%, while its carbon dioxide emissions have been reduced by 15% compared to conventional diesel engines, and emissions have reached Euro III standards. After matching the vehicle, the combustion efficiency of the conventional turbocharged diesel engine is increased by 8%, while the fuel consumption of the 100 km operating condition is reduced by 20%.
Analysts believe that from the performance of Brilliance 1.8T and Great Wall TC diesel engine, the self-owned brand cars are expected to make up for the “heart†flaws in a short time. Taking the Great Wall TC electronically controlled high pressure common rail diesel engine as an example, its outstanding quiet performance will completely change people's prejudice against diesel engines, thus promoting the accelerated development of China's diesel engine market.
China Power
Will become a new driving force for the development of independent brands
At present, Brilliance 1.8T has begun to equip Zunchi and will soon be supporting Huachen’s new Junjie. Analysts believe that both Brilliance and Great Wall will benefit from the new engine. In particular, Great Wall Motor, once Haval and other models are equipped with TC electronically controlled high-pressure common-rail diesel engines, it will subvert the traditional image of domestic SUV vehicles with its advantages such as better acceleration performance, more fuel-efficient performance, and a quieter driving experience. This set off a new boom in the SUV market.
It is reported that in the rapidly developing global diesel vehicle market, the diesel common rail system represents the latest technology and future direction of diesel engines. At present, in addition to Great Wall Motors, the market including Audi, Mercedes-Benz, Huatai and other brands have introduced vehicles using the second-generation diesel common rail system.
