Experimental Research of Starting Control of GD—1 High Pressure Common Rail Diesel Engine

Compared with mechanical fuel supply system,high pressure common rail fuel injection system is able to make the diesel build up high fuel pressure quickly adjust the injection timing and fuel quantity smoothly.Based on GD—1 high pressure common rail injection system,this paper does some research on starting of high pressure commom rail diesel engine by adjusting and controlling injection quantity,injection pressure and injection timing.The results of test indicate that this system can effectively improve the starting characteristic of diesel engine.
