Excessive fuel consumption of diesel generator sets may be caused by low pressure of the high-pressure fuel pump, poor atomization of the fuel injector, low pressure in the engine inner cylinder, or air leakage in the booster pipe. The solution includes cleaning the air filter, adjusting the injection timing, checking the fuel system and repairing or replacing related parts.
Why is the diesel generator set in use fuel consumption is too large? And how to deal with it? If the unit has been used for a long time after the fuel consumption is too large, it may be the piston ring, cylinder liner wear serious, resulting in serious air leakage, then you need to repair or replace the relevant parts.
If it is a new machine or the use of a shorter period of time units appear fuel consumption is too large, it may be the following problems, diesel generator set manufacturers Hunan Super Power New Energy Co.,LTD to give you a solution of the problem.
The cause of excessive fuel consumption of diesel generator sets depends on four aspects:
1. The pressure inside the high-pressure oil pump, the better the sealing, the greater the pressure, the fuel saving. Low oil pump pressure and poor sealing make the stroke of the high-pressure oil pump larger, and insufficient diesel combustion causes high fuel consumption.
2. The degree of atomization of the fuel injector (commonly known as the fuel nozzle), the better the spray, the more detailed the fuel-efficient the fuel nozzle is worn and the seal is not good. The fuel injection is linear, which is obviously more than the fuel sprayed during atomization. When diesel enters the engine It is too late to burn, it is discharged, which consumes a lot of fuel.
3. If the internal cylinder of the engine is low and the valve is poorly sealed and air leaks, the fuel consumption is large; the water temperature in the diesel engine is too high, which makes the engine compression ratio lower, and part of the diesel is discharged through high temperature, resulting in high fuel consumption.
4. The air leakage in the booster pipe causes the air pressure pushed into the high-pressure oil pump to be too low during exhaust gas recirculation. When the throttle is increased, the oil pump cannot reach the amount of oil required by the engine, resulting in insufficient engine power. If the power is not enough, the fuel consumption is large (Note: This article supercharged engine).
Excessive fuel consumption of diesel generator set solution:
1. The air filter is blocked to clean the filter element or replace the filter element.
2. Injector failure, check the injector and replace or repair the injector according to the unit.
3. Incorrect fuel injection timing. Adjust injection timing. According to the different diesel engine models to adjust.
4, fuel system oil leakage, check the fuel line.
5. If the valve clearance does not meet the assembly requirements, check the wear of the parts of the gas distribution system, and repair or replace the parts.
6. If the fuel system leaks oil, check the fuel pump, plunger and delivery valve, and repair or replace it according to the wear of the parts after inspection.
