| Abstract: | Basing on the GD-1 high pressure common rail diesel engine,this paper firstly researched on the control strategy of rail pressure building up at start-up condition experimentally and theoretically.Depends on several experiments on some kinds of different strategies,this paper goes to two efficiently optimized modes of rail pressure foundation at start-up condition.The experimental validation results show that the rail pressure can be built up to the target high value more quickly than before at start-up condition.This improvement provides a good base for further optimization of high pressure common rail diesel engine's start ability and exhaust emission control. |
