摘要
本文利用高速频闪摄像技术和Bosch长管法对BOSCH第一代共轨系统进行了预喷射过程的研究。通过对不同压力下预喷射的喷雾图像和喷油规律分析,找出适宜的预喷射控制方法,从而为整机的电控策略提供依据。
This article has researched the pilot injection process to the BOSCH first generation of common rail system by the high speed pulse light device and the Bosch long tube law. Through analysis to the atomization image and fuel injection rate under different pressure, an appropriate control method in pilot injection is discovered, providing evidences for control strategy used in the engine.
