Frequently Asked Questions about Diesel Generator Rental Use

Frequently Asked Questions about Diesel Generator Rental Use

The air filter is not clean: it will increase the resistance, reduce the air flow and reduce the inflation efficiency, resulting in insufficient engine power. Clean the filter element of the diesel air filter or remove the dust on the paper filter as needed, and replace the filter if necessary.

Blocked exhaust pipe: Blocked exhaust pipes of diesel generator rental units will cause poor exhaust and reduce fuel efficiency. The power drops. Check whether the exhaust pipe resistance increases due to excessive carbon deposits in the exhaust pipe. Generally, the exhaust back pressure should not exceed 3.3Kpa, and carbon deposits in the exhaust pipe should be removed frequently.


The fuel supply advance angle is too large or too small: The fuel supply advance angle of the diesel generator rental unit is too large or too small will cause the fuel pump injection time to be too early or too late (premature fuel injection time will lead to insufficient fuel combustion. If it is too time It is too late, white smoke will be emitted and the fuel will not burn sufficiently), so that the combustion process cannot reach the best condition. At this time, check whether the screws of the fuel injection drive shaft adapter are loose. If it is loose, readjust the fuel supply advance angle and tighten the screws as needed.

Piston and cylinder liner strain: The piston and cylinder liner are severely deformed or worn, and the friction loss of the piston ring increases, which causes the engine's own mechanical loss to increase and the compression ratio to decrease. Small size, difficult to catch fire or insufficient combustion, reduced ventilation expansion and serious air leakage. At this time, the cylinder liner, piston and piston ring should be replaced.

Fuel system failure of diesel generator rental unit:

(1) The fuel filter or pipeline enters air or is blocked, causing the oil circuit to be blocked, insufficient power, or even fire. The air entering the pipeline should be removed, the filter element of the diesel filter should be cleaned, and replaced if necessary.

(2) Damage to the injector coupling may cause oil leakage, jamming or poor atomization, which can easily lead to insufficient cylinders and insufficient engine power. It should be cleaned, ground or replaced in time.

(3) Insufficient fuel supply of the fuel injection pump can also lead to insufficient power. Check, repair or replace supporting parts in time, and readjust the fuel supply of the fuel injection pump. [H]
