用于铁牛-55及东方红-75起动用的二行程汽油机,在起动时排气管或消声器会发出间断或连续爆炸声,俗称“发炮”。造成放炮的根本原因是曲轴箱积油或汽化器向气缸内供给的混合气过浓,造成燃烧不完全,拖延到排气管道里继续燃烧爆炸,而发出放炮声。

Used for the two-stroke petrol engine used for the start-up of Tractor -55 and Dongfanghong-75, the exhaust pipe or muffler will emit intermittent or continuous explosion sound at start-up, commonly known as “firing”. Causing the fundamental cause of squirting is that the crankcase fuel or carburetor mixture supplied to the cylinder is too rich, resulting in incomplete combustion, the delay in the exhaust pipe to continue the combustion explosion, and issued a blasting sound.
