小型风冷柴油机冷起动试验研究

Experimental Investigation Cold Starting for a Small Air-Cooling Disel Engine

文章分析了影响柴油机冷起动性能的因素及涡流燃烧室最佳结构参数匹配，在不采用外加辅助措施的前提下，从改进涡流主副燃烧室的连接通道的形状，起动孔的锥度的大小及位置，燃烧室的形着着手，以保证在-2℃的低温下，柴油机能够顺利起动并且其性能指标（功率，油耗，烟度，噪声等）不低于改进前的性能指标，我们在155F和CZ165F柴油机上进行对比试验，达到了预期的效果。

In this article the influential factors on cold starting of the diesel engine and optimum matching of the best structure parameters of turbulent combustion chamber are analysed .Without taking added supplementary measures,the shape of the channel connecting the main chamber to the auxiliary one,the size and position of stating hole taper,and the chamber shape have been improved to ensure that the engine can be started at -2℃ and that other performance indexes(power,fuel,exhaust smoke condensation, noise an...
