一、前言过去对燃气温度方面的研究,只是从热力学乃至燃烧学的角度出发,以达到提高发动机的性能。最近则不限于此,已对排气的问题给于更大的关心。特别是由于NO的生成量随着温度按指数关系增长,文献(2)指出,除了气缸中的平均温度之外还必须考虑局部的温度差。例如在汽油机中,火焰传播结束时,在火 First, the foreword In the past on the gas temperature research, only from the thermodynamic and even combustion point of view, in order to achieve improved engine performance. This is not the case in the recent past and has given greater attention to the issue of exhaust gas. In particular, as the amount of NO produced increases exponentially with temperature, reference (2) states that in addition to the average temperature in the cylinder, a local temperature difference must be considered. For example, in a gasoline engine, the flame spreads over at the end of the fire
