| Abstract:During the test of certain single cylinder diesel engine, the fuel injector controlling unit went in malfunction. The causes of fault were analyzed by theoretical analysis and experimental verification. The results showed the ultimate cause was the mismatch between the transient parameters of driving circuit and the working requirements of MOSFET. The improved design was introduced accordingly and proven to be effective. |
