Knowledge sharing:
Caterpillar cat323 small excavator shovel has a big gray smoke when lifting the arm, and there is a big black smoke added to the large throttle. What is the reason? The problem of the main fuel injection pump for black smoke is that the diesel combustion is insufficient. Because The large throttle has a large amount of fuel injection and too little air, so the combustion is incomplete, so the black smoke is large.Since the insufficient intake is excluded, there may be poor atomization of the fuel injection nozzle, but there is also a cylinder with insufficient compression ratio. .
