Abstract: Based on the characteristics of the starting process of 2.8TC diesel engine, the starting process is divided into two periods, the towing period and starting period. Different metering valve control strategy of high pressure pump for different period is designed and the targets of the first injection pressure and injection speed are determined. In the towing period, the effects of the opening time and opening size of the fuel metering valve on the dynamic characteristics of the rail pressure are studied by experiment, and the control method of the fuel pump is optimized. In the starting period, the effects of the opening size and control method of the fuel metering valve on the dynamic characteristics of the rail pressure are also investigated by experiment. The results show that the phased control strategy of high pressure pump fuel metering valve can effectively improve the stability and following performance of the target of first injecting pressure in starting process. It provides a good injection condition for improving the starting performance.

Key words: power machinery and engineering, diesel engine, high pressure common rail, high pressure oil pump, starting condition, control strategy
