使用二冲程发动机的摩托车,有时在启动过程中,因点火不良或其他原因,经反复启动无效后,常会引起曲轴箱进油过多。当其他故障排除后,因曲轴箱内积油过多,混合气过浓,给启动带来较大困难时,就应设法排除曲轴箱内的积油。对此问题,本人采取的方法是:拆下化油器,反复启动发动机几次,使曲轴箱内直接吸入大量空气,当汽缸内的混合气一旦达到燃烧条件时,发动机就会着车。发动机在失去油门控制的情 Motorcycles using two-stroke engines, sometimes in the start-up process, due to poor ignition or other reasons, after repeated start invalid, often cause excessive crankcase into the oil. When other troubleshooting, due to excessive oil in the crankcase, the mixture is too thick, causing great difficulties to start, you should try to rule out the crankcase oil accumulation. On this issue, I take the method is: remove the carburetor, repeatedly start the engine several times, the crankcase directly inhaled a lot of air, when the cylinder once the mixture reaches the combustion conditions, the engine will be car. The engine is out of throttle control
