近日在路上见到数台三轮农用车和小四轮拖拉机,它们的空气滤清器油盘外侧下部,被用冲子冲透了一个6～7mm的冲孔,这样油盘就无法盛油了。笔者对此做法有些奇怪,问机手冲孔的原因,据说是发动机不易起动,在这里冲了孔,可向里面注入起动液。 Recently on the road to see several three-wheeled agricultural vehicles and small four-wheel tractors, the outer lower part of their air cleaner pan, was washed with a punch punched a 6 ~ 7mm, so the oil pan can not Sheng oil It’s The author of this practice is somewhat strange, ask the reasons for the punching of the hand, it is said that the engine is not easy to start, punched holes here, can be injected into the starter fluid inside.
