摘要
在电控LPG-柴油双燃料发动机试验的基础上,建立了全程电子调速器模型。通过动态调整油泵齿条位置实现对柴油机突变负载下转速的闭环控制,从而保证在不同工况下转速的稳定性。同时,模型实现了不同负载下,对PID参数进行整定,并将整定后的PID参数用于LR6105双燃料发动机的参数整定试验。经试验验证,此仿真模型能降低转速波动率,从而减少大量调试工作。
Based on the experiment of electric controlled LPG-diesel dual fuel engine, full-range electric governor model was set up. By adjusting dynamic fuel pump rack position,closed loop of engine speed in suddenly changing of load was realized in this model. It could keep engine speed stability in different status of engine. Meantime,the model required PID parameters regulation of speed in all kinds of load. The PID parameters of regulation were used to do the PID parameters regulation experiment on the LR6105 dual fuel engine. According to the experlments,it was proved that the simulation model can not only reduce speed ratio but also save much experiment work.
