摘　　要：由于某2.0L汽油发动机需要提升动力性,计划在原自然吸气发动机的基础上增加涡轮增压器,需要对冷却水套的换热性能进行CFD仿真计算。经过分析发现,原发动机冷却水套无法满足增压发动机的换热需求,需对缸垫排气侧水孔和缸盖排气门鼻梁区右侧水套进行改进。As the need for a 2.0L gasoline engine power upgrade, plans to on the original of the naturally aspirated engine based on increased turbocharger, needed for the cooling water jacket for thermal performance of CFD simulation calculation. After analysis, the original engine cooling water jacket can not meet the turbocharged engine the heat demand, need to improve the cylinder pad on the exhaust side hole and cylinder head exhaust Gate Bridge area on the right side of the water jacket.
