摘要
利用PRO/E建立TBD620柴油机的进气道和燃烧室三维模型;并在FIRE软件中对进气、压缩和燃烧过程进行仿真计算。分析了TBD620柴油机双进气道可控涡流系统对缸内涡流、油气混合和燃烧排放特性的影响。结果表明,低负荷工况时关闭双进气道可控涡流系统的进气控制阀能显著改善缸内混合气的形成,提高柴油机燃烧及排放性能。
The three-dimension substantiality of the TBD620 diesel engine＇s intake port and combustion chamber was constructed on the Pro/E software platform, and the simulation of the intake, compression and combustion process were done with the fluid analysis software FIRE. The effect of the double control- lable intake swirl system on eddies in the cylinder, the mixing of oil and gas, the features of combustion and emissions of the TBD620 diesel engine were analyzed. The results have showed that the intake swirl of the double controllable intake swirl system can ameliorate the diesel engine＇s mixed gas significantly, the low load combustion and emissions performance of the diesel engine are also substantially increased.
