摘　　要：通过在ＳＤ１９５和ＳＤ２１００两种柴油机上应用低旋流进气直喷燃烧系统的试验研究，探讨了燃烧室结构参数和供油系统参数的优化匹配及其对柴油机燃烧性能的影响，对小缸径柴油机推广应用低旋流进气直喷燃烧系统提供了有意义的参考。Experimental investigations on the D.I. combustion system with low swirl intake port applied to both model SD195 and SD2100 diesel engines are made. This paper discusses the optimal matching of the combustion chamber geometric parameters and the fuel supply system parameters and analyses their effect on diesel engine combustion characteristics. Test results show that small bore D.I. diesel engine with low swirl intake port can obtain an excellent performance (SFC for rated output: g e ≤238 g/kW·h; smoke: R b ≤2.4 bosch; cylinder peak pressure: p z max ≤8.5 MPa), provided that the combustion system parameters are reasonably matched. It is of great value to popularize the low swirl D.I. combustion system in small bore diesel engines.
