| Abstract: | In this paper, the strategies of knock detection and knock control of BOSCH gasoline engine management system were presented. The advantages of an engine management system with knock control in terms of power performance, fuel economy and knock safety were discussed. The differences of engine performance and emissions under different knocking intensity as well as the effects of air-fuel ratio and intake air temperature on knock limit spark angle were investigated by engine test. |
