Taking into account random errors in the engine manufacturing process,the effects of main parameters on the peak torque of the engine were studied.First,an engine performance simulation analysis model was built based on GT-Power,and orthogonal experiments were carried out on the main parameters affecting engine performance.The range method was used to clarify that the filter element flow resistance and the crank angle corresponding to the maximum lift of intake and exhaust valves were the main influencing factors of peak engine torque.Secondly,using response surface experimental analysis,it is concluded that the flow resistance of the filter element and the maximum lift of the intake and exhaust valves correspond to the crankshaft angle,and there is basically no interaction between the three.The final research results show that the crankshaft angle corresponding to the maximum exhaust valve lift has the greatest impact on the peak engine torque.
