Reserch on lean burning characteristics experiment based on GDI engine

A GDI engine electronic control fuel injection system has been developed for a GDI engine based on analysing the work principles of the control system of the engine in detail in this paper. Aiming at the petrol straight turbojet injection system, aiming at electronic-controlled engine different speed conditions, the ignition point and in cylinder, the maximum detonation pressure rate, burning duration and 50% wave and the rate of crank shaft injection control experiment, and analyze the detonation pressure curve, detonation pressure curve, burning duration, curve instantaneous fuel consumption curve, etc. Through the engine test proved that the different load and speed control injection quantity required, accord with the rareness burning oil injection control strategy, the design of the control system can guarantee engine fuel injection performance requirements.
