| Abstract: | The three-dimensional mathematical model of combustion process based on a methanol engine was established,and the accuracy of the model was validated.On this basis,the influence of three types of combustion chamber shape(straight port,reduced port and exposure port)on combustion process was studied.The gas flow and turbulent kinetic energy field,combustion pressure,the rate of pressure rise,temperature and NO emissions in the cylinder were treated in detail.The results show that there is proper combustion d... |
