Experience of the Diesel Engine Cooling System Simulation

The cooling system of the designed diesel engine was investigated using specially prepared models. For selected initializations of a cooling fluid in the available cooling jacket, quantitative estimates of the levels of the heat flow to the coolant and of the temperature of the cooling surfaces of various cylinders were made. Changing the terms of the initiation of the cooling fluid flow (for example, the places where the coolant penetrates into the jacket) is accompanied by a significant redistribution of the convective component of the heat sink and this influences the temperature of the cooling surfaces. It is shown that the uniformity of the cylinder cooling and the intensity of cooling of the cylinder heads can be controlled by choice of the place of coolant penetration into the jacket for the considered design of a crankcase and cylinder heads.
