建立了计算涡流室柴油机连接通道流量系数的热力学模型和二堆数值计算模型。首次计算出连接通道流量系数随曲轴转角的瞬时变化规律。计算分析了通道结构参数与发动机运转因素对流量系数的影响。
A thermodynamic model and a two-pile numerical model for calculating the flow coefficient of a vortex chamber diesel engine are established. For the first time, the instantaneous variation of the flow coefficient of the connecting channel with the crank angle is calculated. The influence of channel structure parameters and engine running factors on the flow coefficient was calculated and analyzed.
