Maintenance Methods for Reduced Compression Ratio in Diesel Engines

The compression ratio is closely related to engine performance; relatively speaking, a higher compression ratio results in greater engine power. Generally, with other engine designs unchanged, a higher compression ratio leads to greater power and higher efficiency. However, an excessively high compression ratio can cause reduced stability and shorten engine life. The following is a brief description of maintenance methods for reduced compression ratio in diesel engines:

Diesel Generator Maintenance: Piston Position Too Low at Compression End

(1) Excessively large fit clearance of parts. Therefore, during repair, these fit clearances should be controlled within the allowable range.

(2) Deformation of parts or excessive deviation of main dimensions. Therefore, when replacing parts during repair, operational specifications should be followed to ensure repair quality; at the same time, do not forget to inspect when replacing parts, and avoid replacing with or installing unqualified parts.

Maintenance for Excessively Large Combustion Chamber Volume

(1) Severe wear of valves and valve seats: In this case, the valves and valve seat rings should be replaced.

(2) Cylinder head gasket thickness exceeding design requirements: Replace with a cylinder gasket that meets the requirements.

(3) The top of the piston is concave, and a qualified piston should be replaced at this time.

(4) Burn damage to the swirl chamber on the cylinder head: Replace with a qualified cylinder head.

Do not ignore the inspection of the compression ratio. For diesel generator maintenance work, ensure that all performances of the diesel generator are excellent and that the diesel generator operates well. During maintenance, attention should be paid to the relative positions and order of detachable parts (marking if necessary), the structural characteristics of non-detachable parts, and master the force when reinstalling (using a torque wrench).
