Maintenance Manual of 4M11 Series Diesel Engine For Land Power Generators
The resistance of the air filter shall not be too high. The maximum permissible resistance
shall not exceed 3kPa under non-contaminated state and shall be 5kPa under contaminated
state. Check the maximum intake resistance only when the diesel engine is running at rated
speed under full load. When the intake resistance reaches the maximum permissible limit,
clean or replace the filter element as per the manufacturer's instructions.
Notice: It's absolutely prohibited to run the engine without the air filter,
otherwise the ingress of dusts and impurities into the diesel engine will lead to earlier
wear of engine.
Disassemble the filter element from the air filter and flap lightly the end face to fall
off the dust or blow backward (from inside to outside) by compressed air. Figure2-13 gives
the diagram of cleaning air filter element.
