According to the famous American market research firm GLOBALINSIGHT survey, for the past eight years, the global diesel engine car sales increased by 141%. As you can see, along with the increasing maturity of diesel engine technology in the recent ten years, sales of diesel is made. A senior industry insiders speculated that in 2009, diesel will full beyond gasoline-powered cars. This really the case? But in recent years the development trend of diesel engine, the situation isn't going to happen.

Well known for its speed and endurance is 24 hours of le mans endurance and F1 and the world rally championship (WRC), one of the world's three top car race so far has been successfully held 74 sessions. In 2008, with full aluminium V 12 cylinders diesel engine more than 650 horsepower, torque, power up to 1100 cattle, audi R10 TDI diesel fuel engine technology of le mans race champion, for audi to become the world's first diesel won the le mans car manufacturers. Audi at le mans race win proved that the diesel engine in terms of speed and durability can compete and a gasoline engine.

In terms of fuel consumption, see section of diesel engine oil, gasoline engine in the dust, even if the latest hybrid is also slightly smaller than the diesel engine. Audi do better when it comes to fuel consumption and environmental protection. Having ULES ultra-low emission system TDI engine is currently the world's most clean diesel engines, reformed the common rail system, and efficient exhaust gas recirculation system and optimize the turbocharging system helps to reduce emissions. The audi TDI assembly ULES ultra-low emission system has been achieved in 2014 on the implementation of the Ⅵ emission standards.

Diesel engine can in such aspects as performance, reliability and fuel economy are beyond the gasoline engine, the biggest "contributor" must belong to the third generation of common rail direct injection technology. Common rail diesel injection system of injection pressure and injection process completely separated from each other, in all of the engine speed range to obtain very high fuel pressure, the electronic control system of flexible control of the timing and injection pressure on engine all sorts of conditions are able to obtain low emissions and high efficiency. So it can make the diesel engine with high power and high torque, low fuel consumption, low emissions and low noise characteristics.

At present, the third generation of common rail direct injection technology is mainly applied in suvs, in G320CDI imported cars such as Benz, audi Q7 diesel version, ssangyong love teng, etc., in the domestic car such as huatai hyundai, the Great Wall at harvard, lufeng X6 (parameter configuration gallery), etc. Ssangyong of diesel engine technology is relatively mature, and Mercedes teamed up to build the third generation high pressure common rail direct injection engine, the fusion of the third generation of common rail fuel injection and variable cross-section turbocharging technology, become the world's most advanced diesel system. The third generation engine has flexible electronic control system, control of the timing and injection pressure on engine all sorts of conditions are able to obtain low emissions and high efficiency, and in places such as Australia and China for 40 ~ 50 to minus 30 to 40 degrees Celsius in extreme climate tests showed excellent work performance, its durability and reliability are the prime example.

Thanks to the advanced third generation of common rail system, diesel engine has the gasoline vehicles in the field of economy and environmental protection played a mess, but in terms of performance but also has a tendency to catch up with gasoline vehicles, believe that by 2009, driving in the streets of the vehicles will have more cars are used by the third generation of common rail diesel injection technology as the core.
