Piston ring for P&H 90

The piston ring 18Z1490D7 is a component used within the engine assembly of heavy machinery. It serves to seal the combustion chamber to maintain necessary compression levels, while also scraping excess oil from the cylinder walls to regulate lubrication consumption. Additionally, it aids in the transfer of heat from the piston to the cylinder walls during engine operation.

This component is compatible with the P&H 90 model. It is engineered to meet the specific requirements for fitment and function within the engine systems of this equipment. The design ensures it operates correctly within the cylinder environment to maintain engine efficiency.

Piston rings are typically installed in sets on the piston to manage the pressure and thermal environment of the combustion chamber. By maintaining a seal between the piston and the cylinder wall, these rings prevent the escape of combustion gases into the crankcase and control the distribution of oil, which is necessary for the proper operation of internal combustion engines used in heavy equipment.
