摘要:
针对高压共轨喷油系统在喷油过程中压力波动引起多次喷射稳定性下降的问题,根据系统多次喷射循环喷油量波动特性,建立了系统仿真模型,通过试验验证了模型的准确性。利用所建模型,分别对预-主喷射和主-后喷射中循环喷油量随喷油间隔的波动特性进行研究,分析表明:相同预喷不同主喷时,主喷油量波动幅值随喷射间隔增大而减小,波动周期不随主喷油量增加而变化且波动相位一致,在与整数倍压力波动周期时间差值接近的主喷油持续期内,预主喷射间隔对主喷波动量波动影响规律相似;相同主喷不同预喷时,主喷油量波动幅值随预喷油量增加而增大;相同主喷不同后喷时,随主后喷射间隔增大,后喷油量波动减小,波动周期相同,随后喷油量增加波动幅值变化较小;后喷相同主喷不同时,与整数倍压力波动周期的时间差值相同的主喷持续期,其喷射引起的后喷油量波动规律相似。
