The role of the air filter of a diesel generator set

To generator electricity, diesel generators need the air for its combustion process within the engines. Air Filter is to filter solid particulates such as dust, pollen and mould in the air.

There are many impurities such as dust and sand suspended in the air. If these impurities enter the cylinder with the air, they will accelerate the wear of components such as the cylinder, piston, and piston ring. When larger particles of impurities enter between the piston and the cylinder, it will cause serious "cylinder pulling". The air filter can effectively filter out these dust and sand, protect the internal parts of the engine, reduce wear, and extend the service life of the engine.

If the air entering the cylinder contains a large amount of impurities, it will affect the mixing ratio of fuel and air, resulting in incomplete combustion of fuel, thereby reducing the performance and efficiency of the engine. The air filter improves fuel utilization and reduces fuel consumption and emissions by filtering impurities in the air.

While filtering the air, the air filter can also ensure that the amount of air entering the cylinder is sufficient and stable. Stable air intake is very important for the smooth operation and power output of the engine. It can avoid problems such as engine shaking and power reduction caused by insufficient or unstable air intake.

Therefore, regular replacement and maintenance of air filters is one of the key measures to ensure the normal operation of diesel generator sets.
