摘要
建立了摩托车化油器腔体内部气体流动的二维不可压湍流模型，并对节气门全开、并开及经济工况下的流场进行数值模拟，得出了流场的变化规律．
A 2 D incompressible turbulent model of the gas flow in the motorcycle carburetor is established. Numerical simulation of flow field inside carburetor is carried out as the throttle is under fully opened,semi opened and economical operating conditions. The rules for gas flow under the three working conditions are summerized.
