汽 油机排气管放炮是气缸内未燃烧或未完全燃烧的混合气被排气管或其它气缸排出的高温废气点燃所致 ,表现为排气管排出阵阵浓烟、发动机油耗增加功率下降 ,性能恶化 ,严重时不能工作。汽油机排气管放炮的原因涉及到油路、电路和配气机构等方面。就电路而言 ,主要来自点火系统故 Gasoline exhaust pipe blasting is unburned cylinder or incomplete combustion of the mixture was exhaust pipe or other cylinder exhaust high temperature exhaust gas caused by the performance of the exhaust pipe emits thick smoke, the engine fuel consumption increases power decline, performance Deteriorating, unable to work in serious cases. Gasoline exhaust pipe blasting causes related to the oil circuit, and gas distribution agencies and so on. On the circuit, mainly from the ignition system
