Application Of Fuel Saving Technology For Diesel Generators

5) Carefully calibrate injection advance Angle of diesel generator

Diesel generator is very sensitive to injection advance Angle, so the injection timing mark of diesel generator is marked on flywheel and injection pump. Be sure to align the marks when proofreading. However, due to wear and deformation of transmission parts, the accuracy of injection timing is affected. Therefore, it is necessary to conduct road test correction after proofreading to ensure that the power of the generator set is sufficient and not rough.

6) Ensure the sealing of diesel generator fuel injection pump plunger

7) Remove the following faults of diesel generators:

Eliminate the following faults in time. Avoid diesel generator smoke, knock and unstable operation of the undesirable phenomenon.

Lack of air due to blockage of air filter.

Low injection pressure. Poor injection quality. Cause bad fuel atomization.

The injector drops oil.

Injection too early or too late.

Excessive fuel injection.

8) Strengthen the purification of diesel generator oil

More than half of diesel generator failures are in the fuel supply system. The solution is to buy diesel fuel precipitation for 2-4 days and then use. 91% - 98% of the impurities can be precipitated. If you buy it now, put two layers of silk cloth or toilet paper on the filter screen of the fuel tank of the diesel generator. Can filter the diameter of more than 0. OOlmm impurities.

9) Correct selection of diesel generator fuel oil and lubricating oil

Diesel oil is labeled with freezing point. The light diesel oil produced in China has no. 0, no. 10, No. 20 and No. 35 (freezing point is 0℃, -10℃, -20℃ and -35℃ respectively. In order to ensure smooth oil supply, the ambient temperature should be about 5℃ higher than the freezing point.

The viscosity of diesel oil should also be appropriate, the viscosity is too high, so that the atomization performance is reduced, the combustion is unsafe, the exhaust pipe emits black smoke, the consumption of oil increases. According to the test: compared with the normal viscosity doubled, fuel consumption increased 15g/(KWH). But the viscosity is too low, the oil leakage of the injection pump plunger increases, the plunger lubrication becomes poor, and the wear is serious, so the viscosity of diesel oil should be controlled in the appropriate range.

The compression ratio and heat load of the diesel generator are much higher than that of the gasoline engine, and the corrosion of diesel is larger than that of gasoline, so the diesel generator uses advanced lubricating oil containing additives.
