Abstract:The influence of valve timing on the performance of 6106 diesel engine was studied by using GT-Power software in this paper. The effect of different timing of intake valve close and exhaust valve open, valve overlap on diesel engine performance were calculated and analyzed under full load condition, and different optimum results were obtained by computation. Finally, the test study on the acquired computational results was performed on 6106 diesel engine. The engine torque, brake specific fuel consumption (BSFC) and volumetric efficiency were measured at full load condition. The computational results and test datum before and after optimization were compared, and the difference between them was less than 1%, which verified the validity of the results for performance improvement of diesel engines.
