摘　　要：为满足直喷增压高性能汽油发动机的冷却系统的开发需求,基于典型发动机冷却系统设计,借助现代CAE软件分析能力,计算发动机水套压力、温度、速度分布情况,找出最优设计方案。通过试验充分验证系统中各条水路的阻力、压力及流量分配,实现发动机冷却系统的最优匹配。In order to satisfy the development demand of high performance Turbo Gasoline Derect Injection （TGDI） engine, based on the design of typical engine cooling system, the paper calculates the distribution of engine water jacket pressure, temperature and velocity with the aid of the modem CAE software analysis, then comes up with the optimal design proposal. Therefore, the optimal match of engine cooling system by fully validating each waterway resistance, pressure and flow distribution with experiment is realized.
