当前,在国内外柴油机制造业中,制造高效率和高经济性柴油机的问题,是柴油机发展的主要方向之一。提高中速柴油机单缸功率的主要途径,是提高工作过程的平均有效压力p_(me)。但是,在这种情况下,气缸活塞组件的温度和温度梯度将大为提高,从而严重地限制柴油机强化度的 Currently, at home and abroad in the diesel engine manufacturing industry, the issue of manufacturing diesel engines with high efficiency and economy is one of the main directions for the development of diesel engines. The main way to improve single-cylinder power of medium-speed diesel engine is to increase the average effective pressure p_ (me) of the working process. However, in this case, the temperature and temperature gradient of the cylinder-piston assembly will be significantly increased, severely restricting the strength of the diesel engine
