| Abstract: | A method of three-dimensional numerical simulation w as used to transiently simulate the gas flow during intake process in a motorcycle engine. By analyzing the distributions of velocity, pressure and turbulence kin etic energy (W), and calculating the integrated parameters, such as intake c harge, in-cylinder mean pressure and mean W, the effects of different intak e-valve layouts on intake process were studied. The results of calculation indi cated that larger intake-valve obliquity was favorable for intake process. |
