| Abstract: | 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. |
