Is Fuel Consumption Of Diesel Generator Related To Daily Maintenance

When using 550kw diesel generator, maybe you are care about its fuel consumption and think whether daily maintenance affects fuel consumption. According to our experience in generator maintenance, we think fuel consumption of 550kw diesel generator is also related to daily maintenance. Here we will shares with you.

The untimely maintenance of the diesel engine causes incorrect inspection and adjustment, or defects in some parts of the diesel engine. Although diesel engine can still work, the diesel combustion is insufficient and the exhaust pipe emits black smoke, resulting in increased fuel consumption. During daily use, diesel engine shall be tested and maintained mainly according to the following instructions:

1. So far, we can reduce fuel consumption through below ways: increase air supply to form oil-air mixture ratio to fully burn the fuel to play its full efficiency; Change oil molecular structure and increase engine efficiency; Control oil supply to make it fit diesel engine to reduce fuel consumption.

2. Optimize valve parts and intake and exhaust system: the valve is not tightly closed, the opening height is small, and the opening time is short. The valve timing is disordered and the air filter is not clean, resulting in insufficient intake and unclean exhaust. The air mixed with diesel is reduced due to insufficient air intake, which increases the proportion of oil and gas. The exhaust is not clean, so that some burned exhaust gases cannot be discharged and re participate in oil-gas atomization and mixing, which affect the full combustion of diesel.

The clearance of inlet and exhaust valves shall be adjusted correctly, valve clearance shall be checked regularly, the air filter shall be cleaned and maintained, and carbon deposit on the inlet and exhaust pipes, silencers and valve shall be cleaned to ensure the smooth intake of diesel engine. So as to fill cylinder with fresh air, eliminate exhaust gas and reduce the carbon deposit at the valve.

3. Oil supply part: excessive oil supply or inaccurate oil supply advance angle can also lead to insufficient fuel combustion. When the diesel engine is used for a period of time, it may be wear, at this time, fuel supply advance angle will be reduced, resulting in too late fuel supply time and greatly increased fuel consumption. If oil supply advance angle is small, oil supply will be too late, and if oil supply advance angle is large, the oil supply will be too early. Too early or too late oil supply is not conducive to the uniform distribution of diesel in the whole combustion space, resulting in small mixing and difficult full mixing of oil and gas. Moreover, the air temperature in the cylinder is low and the natural conditions of fuel are poor, which leads to the deterioration of combustion and the insufficient combustion of diesel. Therefore, we should ensure the oil supply angle is at an suitable angle.

4.Oil pump and fuel injector: oil pump and fuel injector are the key parts for the formation and combustion of combustible mixture. Fuel injection law and quality directly determine whether diesel can be burned. Therefore, it is necessary not only to adjust the oil supply advance angle, but also to regularly check the working performance of various components, and do not operate with diseases. The parts worn to the specified service limit shall be replaced in time. The fresh air entering the cylinder shall be sufficient as far as possible. In addition to the insufficient air supply caused by the above valve opening height, closing tightness and cleanliness of the air filter, the sealing of the cylinder head, the size and fit clearance of the piston, cylinder liner and piston ring have a great impact on air supply. Diesel engine shall be tested in time after working for a period of time. If matching clearance is inconsistent, it shall be repaired or replaced in time. At the same time, the injection pressure of the fuel injector can be adjusted to reduce fuel consumption.

Many users who use diesel generator sets will find that they will consume too much fuel after using them for a period of time. In this case, although it can be used, it will cost a lot to use. Is such use normal? We all know that diesel generator set is a recognized type of generator with low fuel consumption in the market. Therefore, if the diesel generator set consumes too much fuel, it must be that some parts have failed.

In order to reduce fuel consumption of 550kw diesel generator set, we should pay attention to daily maintenance and do maintenance regularly. Therefore, if you also find above matters during the use of diesel generator set, you can check it according to the above matters.
