Based on the analysis of unit pump control principle, the hardware and software were designed according to high real-time performance of injection system on diesel engine. Accurate and real-time injection control was realized by using engine position synchronization (EPS) and angle clock conversion concept. The highest injection accuracy is reached to 0.023 4 degree of crank angle, solenoid valve peak current is 12 A and solenoid valve hold current is 8 A. The experimental results show that the whole system can control injection accurately and includes backup function of crankshaft signal.
