冬天气温低,柴油机起动困难。为了克服这个缺陷,我们通常使用的办法是在柴油机的进气岐管上安装预热器,通过预热发动机的进气,来提高发动机的冷车起动性能,减轻起动电动机的负荷。但在使用过程中,由于一些驾驶员不了解预热器的工作原理和使用维护方法,使预热器过早损坏。 Low winter temperatures, difficult to start diesel engine. In order to overcome this defect, we usually use a preheater installed on the intake manifold of the diesel engine to preheat the intake air of the engine to improve the cold start performance of the engine and reduce the load on the starter motor. However, during use, the preheater is prematurely damaged as some drivers do not understand the working principle of the preheater and how to use and maintain it.
