外文文献 Development of R190 diesel engine One. A foreword The development of diesel engine has more than 100 years of history， to human production and life has brought extraordinary convenience， also provides a extraordinary power to the development of human society. In more than a century of development， the diesel engine technology has appeared three qualitative leap. In the industrial developed countries， the truck basically all use diesel engine. In recent years， along with the diesel engine turbocharger， cold， direct injection， exhaust catalytic conversion and particle capture and other advanced technology， diesel engine emissions has reached Euro III and Euro IV emission standard， which set off a climax of car diesel engine， Volkswagen， general motors in the United States， Toyota Motor Company of a large car company car also uses the diesel engine. In China， the oil resource is becoming more and more scarce， the development of diesel vehicles will be the future focus of the automotive industry. Currently on the market of diesel passenger cars mainly MPV and SUV models， imported cars have the Touareg， Phaeton， Dodge Charger etc.， the independent brand are the Great Wall hover， Kairui. Diesel engine compression ratio， high thermal efficiency， fuel consumption than the gasoline engine lower by 30% to 40%， with the car with diesel and gasoline compared and low processing cost 5%， with the common attention of automotive energy all over the world， automobile engine to diesel engine development is the trend of the global automobile industry development. In addition to the fuel consumption than the gasoline engine is low， the diesel engine and gasoline engine compared to 1. The thermal efficiency is high; 2 units power low weight;. Widely used in exhaust gas turbocharger and improve the degree of supercharging; 4. Diesel engine without ignition system， so fault is less easy maintenance and reliable work. But the speed is lower than the gasoline engine， the quality is bi
