本文对机车用四冲程增压柴油机的传热状况进行了研究.采用了各种最新的传热系数公式对机车柴油机的传热量进行计算,并与试验结果进行了对比.另外还对不向的气缸壁温度时柴油机的散热状况进行了研究,得出不同缸壁温度对柴油机性能参数的影响.
In this paper, the heat transfer of a four-stroke turbocharged diesel engine for a locomotive is studied, and the heat transfer coefficient of a locomotive diesel engine is calculated by using the latest heat transfer coefficient formula and compared with the test results. Cylinder wall temperature of the cooling conditions of the diesel engine was studied to obtain the different cylinder wall temperature on the performance parameters of diesel engine.
