The combustion of a micro-piston internal combustion engine with platinum wire glow ignition is diagnosed. The results show that the combustion starting point of the micro piston internal combustion engine varies greatly, and the combustion duration is various and long. The coefficient of variation of p max is as high as 28.5%, the combustion stability is poor. Therefore, it is suggested to improve the thermal environment in the cylinder to improve the combustion stability. One method is to increase the temperature in the cylinder to reduce the duration and the cyclic variation of combustion. The other method is to increase the temperature of the platinum wire to improve the stability of the starting point of combustion and to reduce the cyclic variation of combustion. The test results show that with the increase in the cylinder body temperature, the distribution of combustion starting point is more concentrated, and the coefficient of variation of p max decr...

微型往复活塞式内燃机的燃烧稳定性研究

诊断了带有铂丝辉光点火的微活塞内燃机的燃烧。结果表明，微型活塞内燃机的燃烧起点变化很大，燃烧持续时间长而多样。p max的变化系数高达28.5％，燃烧稳定性差。因此，建议改善气缸中的热环境以提高燃烧稳定性。一种方法是提高气缸中的温度，以减少燃烧的持续时间和周期性变化。另一种方法是提高铂丝的温度，以提高燃烧起点的稳定性并减少燃烧的循环变化。试验结果表明，随着缸体温度的升高，
