Study on simulation and optimization of engine valve timing

In a single-cylinder gasoline engine for the study, made a simulation optimization method of engine valve timing. After the construction of a simulation model of the engine, the simulation results are compared with the data of engine bench test to verify the accuracy of the constructed model. For improving the engine power performance, valve timing optimization simulation to this model is carried out under 4500 rpm, finally the reasonable valve timing is defined under the speed.
