Abstract
In order to meet the requirement of main and pilot injections in an electronically controlled diesel engine, the dwell time between two injections of piezoelectric injector was analyzed. The structure and work principle of piezoelectric injector were briefly described. The effect factors of dwell time were analyzed, such as hydraulic delay time and electric response time, and the determining rule of interval time of main injection and pre-injection was presented. The experimental data was used to verify the effect of interval time between two injections, and measure the real minimal interval time between two injections. The effects of the injection pressure in high pressure line and the interval time between two injections on the fuel injection quantity were analyzed.
