1.油料配比油料配比工作容易被忽视,特别是新机手。有的不加机油、有的不严格按规定加机油(新机50小时以内,汽油与机油按15∶1混合,50小时以后按20∶1混合)。这样,会导致发动机磨损加快,故障增多,寿命缩短. 2.螺钉松动点火提前角调整螺钉又是磁电机的固定螺钉,发动机经过长时间高速运转后容易松动,导致点火线圈铁芯与飞轮(磁电机盖)发生摩擦,温度升高,烧坏初级线圈。因此,汽油发动机在进行技术保养时,应检查固定螺钉是否松动,不可忽视。另外。在排除汽化器倒喷故障时,不可忽视量孔螺钉是否松动脱落。这
1. Oil ratio Oil easily work to be neglected, especially the new drivers. Some do not add oil, and some do not strictly according to the provisions of the oil (within 50 hours of the new machine, gasoline and oil mixed by 15: 1, after 50 hours by 20: 1 mixture). This will lead to accelerated wear and tear of the engine, increased failure, shortened life .2 screws loose ignition advance angle adjustment screw is a magneto fixing screw, the engine after a long time after high-speed operation easily loosen, resulting in ignition coil core and flywheel Motor cover) friction occurs, the temperature increases, burned the primary coil. Therefore, the petrol engine in the maintenance of technology, should check whether the set screws loose, can not be ignored. In addition. In the exclusion carburetor pouring failure, we can not ignore whether the loose hole screw loose. This
