Årsaksanalyse og løsning av dieselmotorflyging

Fenomenet med dieselmotorflyging er fenomenet at under driften av dieselmotoren, spesielt i prosessen med middels og liten belastning, øker hastigheten til dieselmotoren kraftig av en eller annen grunn, overhastighetsdriften kan ikke kontrolleres automatisk, avgasser avgir tykk røyk, og lyden og vibrasjonen er stor.

After the occurrence of "flying", with the increase of the speed of the diesel engine, the leakage between the plunger of the fuel injection pump and the plunger sleeve decreases, and the diesel oil entering the cylinder increases, causing the speed of the diesel engine to increase again, thus forming a vicious circle. The increasing speed of the diesel engine makes the temperature in the cylinder increase continuously, the expansion of the piston increases, the movement of each part of the piston connecting rod group intensifies, and the load increases. Severe accidents such as broken crankshafts and smashed pistons, cylinder liners and heads. Therefore, once the diesel engine "flying", measures must be taken to shorten the "flying" time and reduce losses.
