The power generation unit is insufficient, the cause analysis of the thick black smoke: There are two types of engine power, uneven speed, and the phenomenon of exhaust pipe rowless black smoke has the following: one is a continuous black smoke; the other is to intermittent black smoke, and the engine is shaking.
(1) reason Insufficient engine power and continuous black smoke is excessive from most cylinders or all cylinders of the engine, and the fuel and air mixing ratio are disordered. When combustion, severe hypoxia, diesel combustion is incomplete, suspended free carbon elements The exhaust gas is formed together. If the exhaust pipe is intermittent black smoke, it is accompanied by \"Suscitation \", indicating that the individual cylinder is not complete.
The reason is as follows: 1 The injection pump is improper, so that the oil supply is too large, the combustion is incomplete. 2 The injection quality of most injectors is poor. 3 When oil supply is incomplete. 4 The intake door is lowered, and the opening time is postponed, resulting in insufficient intake. 5 Air filter cartridge is too dirty or air filter installation is incorrect, so that the air is not smooth. 6 The gas quality is too bad. 7 The supercharging efficiency of the pressurizer drops.
Our company sells various brands, models, specific diesel generators all year round, and provides after-sales service.
