在-35℃的低温试验环境下，冷冻柴油机、电瓶、柴油等相关试件并保温，研究了起动液、酒精喷灯、“起动液＋曲轴箱空气加热器”、“进气预热器＋电热塞”等起动方法的可行性。结果表明：喷起动液和“起动液＋曲轴箱空气加热器”的辅助起动方法可使左进气温度、右进气温度、气缸盖温度有一定的升高，但不能辅助柴油机起动成功；酒精喷灯加热油底壳增加了润滑油的流动性，减小柴油机起动的摩擦阻力，从而促进了柴油机成功起动；“进气预热器＋电热塞”同时加热进气的方式确保升高并维持进气温度，促使柴油机成功起动。进一步分析可知，进气加热和润滑油加热的方法更利于柴油机的低温起动。

Diesel engine ,storage battery and diesel fuel were frozen and kept cold insulation at -35 ℃ .The start feasibility of starting fluid ,alcohol blow torch ,starting fluid and crankcase air heater and intake preheater and glow plug was researched . The results show that the assistant method of starting fluid or starting fluid and crankcase air heating can achieve a certain tem-perature rise of left intake ,right intake and cylinder head ,but cannot make diesel engine start successfully .The alcohol blow-torch heating oil sump increases the fluidity of lube oil ,decreases the friction resistance of engine start and promotes the suc-cessful start of diesel engine .The intake preheater and glow plug can maintain and even increase the intake temperature ,so diesel engine can start successfully .The further analysis shows that the intake air and lube oil heating are more beneficial for the low temperature start of diesel engine .
