由于结构上的特点,小型风冷柴油机比小型水冷柴油机容易发生因烧机油而飞车的故障。有的新风冷柴油机每工作半小时就飞车一次,有的旧风冷柴油机一天要飞车好几次。 165F、170F等小型风冷柴油机气门室内的零件是采用飞溅负压式机油润滑:在缸盖进气道上钻一个φ3毫米的通孔至缸盖上平面,在发动机进气行程,空气不仅从空气滤清器进入气缸,还通过此φ3毫米通孔由气缸盖罩内进入气缸。由于此通孔的存在,使气缸盖
Due to its structural characteristics, small air-cooled diesel engines are more prone to speeding due to burning oil than small, water-cooled diesel engines. Some new air-cooled diesel engine every half hour work time on the fly, and some old air-cooled diesel engine several times a day to speed. 165F, 170F and other small air-cooled diesel engine valve parts are splash negative oil lubrication: Drill a φ3 mm through hole in the cylinder head intake to the cylinder head plane, the engine intake stroke, the air not only from the air The filter enters the cylinder and also enters the cylinder through the cylinder head cover through this φ3 mm through hole. Due to the presence of this through hole, the cylinder head is made
