This article introduces the requirements of electronically controlled fuel injector and the shortage of the high-speed electromagnetic valve used in the homeland now and suggests the design philosophy of new 2D injector on diesel engine with common rail fuel injection system. Through axial movement of the controlling valve, the amount of gush of oil is changed. Through the revolution movement of the controlling valve, the time of injecting fuel is changed. Through the establishment of mathematical models and simulation of MATLAB, the responsibility of injector is extremely improved and ideal injection rate shape is gained.
