燃烧室壁面积炭层的形成及其对壁面瞬时温度和瞬时热流量的影响

The Formation of Deposit on the Combustion Wall and the Effects of Deposit Layer on the Instantaneous Temperature and Heat Flux

在一台单缸柴油机上，通过采用着火前后倒拖工况运行，研究燃烧室壁面积炭层的形成及其随发动机运行工况、运行时间、燃烧室壁面位置等的变化规律，以及镀层表面积炭层对测量壁面瞬时温度、瞬时热流量的影响。

In this paper, the formation of the deposit on the combustion wall asthe function of engine operating conditions, operating time,different positions of combustion wall, as well as the effects of deposit layer of the combustion suffecc on the measuring results of the instantaneous temperature by surface thermocouples and heat. fluxcalculated are studied under the conditions of before and after ignition on a motoredsingle cylinder engine.
