In the statistics of the cost of diesel generator set use, when there is a large amount of fuel consumption at a certain stage, it is necessary to consider whether the fuel supply of the injection pump is too high. The common reasons for the fuel supply of the diesel generator set are the following three reasons:

1.Excessive fuel supply of fuel injection pump


2. The adjustment screw that restricts a large number of racks in the speed adjuster has been adjusted too large, or the throttle handle restriction screw has been adjusted


3. Excessive oil in the governor will increase the supply of oil and cause "tag cars". When the fuel supply is too large, the fuel consumption increases and the fuel is not completely burned. The diesel generator exhaust is black smoke, which accelerates the serious carbon deposits in the combustion chamber, accelerates the wear of the cylinders, pistons and piston rings, and even the diesel generator set Overheating and bumping.


Therefore, the specific inspection of this unit can only be performed based on the three common reasons mentioned above. The increase in fuel consumption is not necessarily the cause, but it could also be oil.
