Haixing Power teaches you how to solve the problem of excessive fuel supply and increased fuel consumption

Generator setIf the fuel injection pump supplies too much fuel, it will increase fuel consumption and easily lead to incomplete combustion, causing wear of the cylinder, piston and piston rings, and even causing overheating and cylinder knocking of the diesel engine.

To determine the amount of fuel supply, you can open the side cover of the fuel injection pump for detailed inspection based on the smoke exhaust situation. Haixing summarizes the reasons for excessive fuel supply from the fuel injection pump based on past maintenance experience as follows:

① The fuel injection pump plunger is adjusted so that the fuel supply volume is too large, or the adjusting ring gear locking screw is loose and the adjustment gear is displaced, causing the fuel injection pump fuel supply volume to be too large.

② The adjustment screw that limits the rack oil volume in the builder is too large or the throttle handle limit screw is adjusted too large.

③ Too much engine oil in the speed regulator will increase the oil supply and lead to 'speeding'.

In addition, attention should also be paid to phenomena such as uneven oil supply that may occur during use, resulting in unstable operation of the diesel generator set, reduced power, and intermittent emission of black smoke from the exhaust pipe during cycles.
