内燃机机体热损失的测量主要是缸内壁面的传热测量。此外,为了利用排气能量和控制排气,对排气管的传热也进行测量。因为其测量技术基本相同,所以本文着重对进行多次研究的缸内壁面热流测试方法的现状加以评述,并对它的发展作以展望。 Internal combustion engine heat loss measurement is mainly the cylinder wall heat transfer measurement. In addition, in order to utilize the exhaust energy and control the exhaust gas, the heat transfer of the exhaust pipe is also measured. Because the measurement techniques are basically the same, this paper reviews the current status of the in-cylinder wall surface heat flow test method for many studies, and gives a prospect of its development.
