热能学作为一门科学,大部分是从事传热方面的各种研究。有关内燃机(在地球上系使用最广泛的一种形式的热机)的科学在这方面也不能除外。而恰好相反:每一台新柴油机的问题,首先就是如何保证其缸套活塞组各零件具有一定的热工作状态问题。随着单缸功率的提高和现有柴油机向使用低质重油的过渡,解决这个问题就更加复杂了。正是因为这一点,近十年来,内燃机传热领域内的理论和试验研究工作都非常活跃,并出现了一系列专 Thermal science as a science, most of them engaged in various aspects of heat transfer research. The science of internal combustion engines, one of the most widely used form of heat engines on Earth, can not be excluded in this regard. But on the contrary: the problem of each new diesel engine, first of all, is how to ensure that the cylinder liner piston parts have a certain hot working condition. Solving this problem is even more complicated as single-cylinder power increases and the transition from existing diesel engines to the use of low-quality heavy oil. Because of this, in recent ten years, the theoretical and experimental research work in the field of internal combustion engine heat transfer has been very active, and a series of special
