The diesel advantage in terms of energy saving and carbon dioxide emissions, it is all heat engines, including gasoline, including irreplaceable, therefore, advanced small high-speed diesel engines, their emissions have reached the Euro III standard, a "green engine" has become the new power plant many European and American cars. Characteristics of conventional censtar fuel dispenser engines Diesel features: thermal efficiency and economy better way to improve diesel engine using compressed air temperature, the air temperature dispenser fuel pump exceeds the spontaneous combustion of diesel ignition, then re-injected into the diesel fuel, diesel spray and air mixture ignition while their burning. Therefore, diesel engine without ignition system. Meanwhile, the diesel engine fuel injection system is relatively simple, so the reliability of the diesel engine is better than gasoline engines. Due to restrictions from deflagration and spontaneous combustion of diesel fuel needs, diesel compression ratio is high. Thermal efficiency and economy are better than gasoline engines, while in the case of the same power, torque diesel engine, low speed maximum power, suitable for use laden car.
