摘　　要：在进气道稳流试验台上对2种方案的切向进气道和ZH1105W柴油机进气道进行稳流试验研究,通过试验所获得的无量纲涡流数和流量系数来评价不同气道流通特性的优劣,以确定最终的气道布置方案.实验表明,对比选择后的4105柴油机切向进气道与改进后的ZH1105W柴油机螺旋进气道相比,在保证缸内涡流强度基本不变的情况下,进气道的流量系数明显高于ZH1105W柴油机的螺旋进气道,流量增幅高达35%.Two tangent intake ducts of 4105 diesel engine and another one of ZH1105W diesel engine were investigated on the intake steady flow test-cell. Dimensionless vortex parameter and flow rate coefficient were obtained to evaluate these ducts to determine the final duct disposal. The result has shown that, with the nearly same vortex intensity of ZH1105W, the flow rate coefficient of the tangent intake duct of 4105 diesel engine is increased by 35 %.
