摘要
为摸索CA6DL1-32柴油机配自主共轨系统的冷起动策略,使用自主开发的电控高压共轨系统,并设计了起动控制策略,主要包括对主喷油量、主喷定时以及起动轨压的控制。试验结果表明,采用自主高压共轨系统控制策略能在不增加任何硬件设备的基础上大幅提高6DL柴油机的冷起动性能,满足实际车用柴油机的使用要求。
Independent electronically-controlled high pressure common rail system was used to explore cold starting strategies of CA6DL1-32 diesel engine,and cold starting control algorithms were designed,including main injection fuel,main injection timing and staring object pressure.It was showed by results that performance for cold starting capability of the engine can be extremely improved through independent common rail system and optimized control strategies without any auxiliary devices,so code starting capability of the engine can meet actual requirements of automobile.
