摘　　要：装载机经常在低温环境下启动然后开始工作,起动性能是保证正常工作的主要因素之一,因此研究装载机用柴油机低温起动性能是很有必要的。通过理论计算、预热参数设计、试验验证的方法对装载机用柴油机低温起动性能进行了研究,试验结果表明,进气预热和冷却液预热两种不同的预热方式对柴油机低温起动性能影响不同。因此,装载机用柴油机为了保证不同低温环境的起动性能,需要根据不同的使用环境温度,选配合理的预热方式。Loaders often work in low temperature environments,starting performance is one of the key factors to ensure normal operation,therefore,it is necessary to study the low temperature starting performance of diesel engines for loaders.Through theoretical calculations,pre-heating parameter design,experimental tests,etc.The test results prove that the two different preheating methods of intake air preheating and coolant preheating have different effects on the low temperature starting performance of diesel engines.therefore,in order to ensure the starting performance of different low-temperature environments,diesel engines for loaders,need to be based on different use environment temperature,Optional reasonable preheating method.
