UPPER PISTON RING

UPPER PISTON RING

Description du produit:

The purpose of Maserati part number 479022402, the upper piston ring, is to seal the combustion chamber and prevent the escape of gases into the crankcase. It also helps to control oil consumption and heat transfer from the piston to the cylinder wall.

The upper piston ring is typically made of a high-strength material, such as cast iron or steel, and is coated with a thin layer of chrome or tin to reduce friction and wear. It is installed in a groove at the top of the piston and is compressed by the cylinder wall as the piston moves up and down.

When the piston is at the top of its stroke, the upper piston ring forms a tight seal against the cylinder wall, preventing combustion gases from escaping into the crankcase. This helps to maintain compression and power output.

As the piston moves down the cylinder, the upper piston ring helps to control oil consumption by scraping excess oil from the cylinder wall. This oil then flows back to the crankcase, where it can be reused.

The upper piston ring also helps to transfer heat from the piston to the cylinder wall. This helps to keep the piston from overheating and prevents premature wear.

Upper piston rings are typically replaced during engine rebuilds, but they may also need to be replaced if they are worn or damaged. Signs of a worn or damaged upper piston ring include increased oil consumption, decreased engine power, and blue smoke from the exhaust.

If you suspect that the upper piston rings in your Maserati engine need to be replaced, it is important to have the work done by a qualified mechanic.
