一类大功率气体燃料发动机电控喷射装置的设计
Design of an Electronically Controlled Injection Device for Heavy—duty Gas Engine
摘要
Abstract
According to the fact that the scavenging effect of heavy-duty gas engine is insufficient, and problem of low control precision of the air-fuel ratio and slow response,an injection device using the moving-coil electromagnetic linear actuator and mushrooms type valve structure was proposed herein. The electronically controlled injection device can achieve multiple-point sequential and intermittent fuel injection. The design and the principles of the main design parameters determination were discussed. The design of injection device was completed and a prototype was developed. The digital controller of the injection device was also developed for characteristic tests. The results show that the technical solution can meet the engine's requirements of high flow rate and response.关键词
