近年来，国内进口了一定数量的俄罗斯产工程机械，而其中大多数为汽油机启动，而汽油机又由电起动机或人力绳拉启动。这种启动方式的优点是启动可靠，气温在-40℃时也能可靠的启动，具有很大的拖动潜力，适合用于在严寒条件工作的大功率工程机械的柴油机上。但这种启动方式结构 In recent years, a certain amount of Russian-made construction machinery has been imported into the country, most of which are started up by the gasoline engine, which in turn is started by an electric starter or manpower rope. This kind of starting method has the advantage of reliable start-up, reliable start-up even at -40 ° C and great dragging potential. It is suitable for diesel engines of high-powered construction machinery working under severe conditions. However, this start-up structure
