The traditional mechanical diesel injection engine can not be a better moment to the fuel injection and fuel injection process control, has been unable to meet the requirements of energy-saving and environmental protection. Under these conditions, the electronically controlled common-rail diesel injection system came into being, and has been a rapid development.
