1. Fuel supply issue:
Insufficient fuel supply: The power of diesel generators depends on the supply and quality of fuel. If the fuel supply is insufficient, it will lead to incomplete combustion, thereby reducing the power of the generator.
Poor fuel quality: Impurities or pollutants in the fuel may also affect combustion efficiency, thereby reducing the power output of the generator set.
2. Mechanical failure:
Engine component wear: Long term use, wear or failure of engine components (such as cylinder, piston, valve system wear, crankshaft and connecting rod looseness, etc.) can affect power output.
Turbocharger malfunction: including wear of turbocharger bearings, inaccurate radial positioning, friction between rotor and chamber wall, etc., all of which may cause a decrease in engine speed and insufficient intake pressure.
3. Issues with the intake and exhaust systems:
Air intake system malfunction: such as clogged air filter, turbocharger malfunction (such as excessive axial and radial clearance, mechanical sticking of exhaust bypass valve, etc.) can lead to a decrease in the amount of air entering the cylinder, affecting combustion efficiency.
Exhaust system malfunction: If there is a mixture of carbon deposits or unburned fuel and impurities in the exhaust pipe, it can cause the exhaust pipe section to become smaller and the exhaust to be blocked, which can also affect the power output of the generator set.
4. Electrical system issues:
Electrical system failures, such as aging wires, loose connections, and heavy circuit loads, can all lead to low power.
5. Cooling system issues:
Poor heat dissipation: If the heat dissipation system of the generator is poor and cannot effectively dissipate heat, it will cause the generator to overheat, thereby reducing power output.
6. Lubrication system issues:
Increased impurities in lubricating oil: The amount of impurities in lubricating oil can determine the degree of wear of various lubrication components inside the diesel generator set. Excessive impurities can affect the normal operation and power output of the engine.
Reduced oil pressure: The level of oil pressure can determine the wear of bearings. The lower the oil pressure, the larger the wear clearance of bearings, which in turn affects power output.
7. Engine operating conditions:
Low engine water temperature: It is easy to cause premature wear of the generator set, as the temperature is too low, which can lead to excessive clearance between the cylinder liner and piston of the generator, causing the piston to shake and cause early wear when moving in the cylinder.
The increase in diesel consumption is related to factors such as adjusting the fuel volume of the fuel injection pump, oil leakage from the fuel injector, poor cooling effect, poor sealing of the intake and exhaust valves, poor quality of lubricating oil, and low cylinder pressure.
For these common reasons, the following solutions can be taken:
Regular maintenance of equipment: clean the air filter, clean the fuel system, etc., to ensure the normal operation of the equipment.
Use high-quality fuel: Avoid using inferior fuel or fuel containing excessive impurities.
Improve operating environment: Ensure that the generator set operates in a suitable temperature and humidity environment, reducing interference from dust and humidity.
Replace worn parts: Replace worn or aged parts in a timely manner, such as cylinder liners, piston rings, etc.
