Petrol dispenser pump automatically change the fuel supply

Petrol dispenser pump due to work pressure, requiring the relevant parts with high structural strength and stiffness, so  relatively heavy, bulky; fuel injection pump and nozzle manufacture high precision, so the higher costs; addition, engine rude, noise and Vibration large; not evaporate, winter cold car difficult to start. Because of these characteristics, the previous engines are generally used for large and medium-sized heavy-duty trucks. The new development of small high-speed engines: the European III emission standards have been reached number. Traditionally, due to relatively heavy engines, liter gasoline engine power indicator gas transfer pump is better (lower speed), high noise, vibration, soot and particulate (PM) emissions of more serious, it has been rarely cars of all ages. But with recent advances in technology, especially the new development of small high-speed petrol dispenser pump engines, a number of advanced technologies, such as electronically controlled direct injection, common rail, turbocharged, intercooled and other technology to the small engine applications that shortcomings exist in the original engine to get a better solution, while advantage in energy efficiency and CO2 emissions, it is all heat engines, including gasoline, including irreplaceable, therefore, advanced small high-speed engines, which Euro III emission standards have been reached number, a "green engine" has become a new power plant in many European and American cars, it is foreseeable that China will be more and more cars. In fact, the working process of the diesel engine with the same gasoline engines, each working cycle also experienced intake, compression, for power, four stroke exhaust. However, due to the fuel is having a viscosity larger than that, does not readily evaporate, but the autoignition temperatures are lower than that of gasoline, thereby forming a combustible gas mixture and the ignition mode are different from the gasoline engine.
