汽车发动机各种正时齿轮的安装方法,因车型而异,现作简要介绍,供同行参考。1.各种齿轮记号一定要对准对好。发动机型式不同,各齿轮上打的记号也不相同。例如,日野 EC100型发动机,各齿轮上的记号为1、2、3,安装时需将曲轴齿轮上的标记1与中间齿轮上1的标记相对;喷油泵驱动齿轮上的标记3应与中间齿轮上的标记3相对;凸轮轴齿轮的标记2应与中间齿轮上的标记2相对。 Car engine installation of various timing gear, due to different models, are briefly introduced for peer reference. A variety of gear marks must be aligned right. Different types of engines, the mark on the gear is not the same. For example, the Nissan EC100 engine, the gear on the mark 1,2,3, the installation of the crankshaft gear on the need to mark 1 and the middle gear on the 1 mark; injection pump drive gear mark 3 and the intermediate gear Mark 3 on the camshaft gear; mark 2 on the camshaft gear should be opposite to mark 2 on the idler gear.
