Piston underside cooling

Piston underside cooling is an important component of modern internal combustion engines and serves to cool the underside of the piston. Engine oil is sprayed directly onto the underside of the piston via special oil spray nozzles or cooling channels. This technique reduces the thermal stress on the pistons and contributes significantly to the stability and lifespan of the engine.

Especially in high-performance gasoline and diesel engines, high temperatures are generated in the combustion chamber. Piston underside cooling efficiently dissipates this heat, reducing material stress and preventing damage such as piston seizure, overheating, or premature wear. Simultaneously, the oil flow provides additional lubrication to the piston pin and cylinder wall.

Cooling is usually achieved via oil jets integrated into the engine block, which are supplied by the oil pressure system. These jets open at a specific oil pressure and spray the oil precisely onto the underside of the pistons. The flawless operation of these components is crucial for the thermal stability of the entire engine.
