Abstract

Diesel injection equipment is required to be more accurate and higher in pressure to meet the increasingly strict emission, fuel consumption regulations and higher engine performance. One of the key component to meet these demands is Injector. DENSO has been working to develop injector according to the following concepts, increasing injection pressure, developing a new control valve and locating the actuator and control valve near the nozzle. This paper reports the new solenoid injectors performance combining high pressure up to 250MPa and injection accuracy performance comparable with the piezo injector, as well as excellent fuel robustness and reliability.
