Piston - Cylinder Head OM904 Euro 4/5
Detroit Diesel

The piston for the cylinder head assembly is a fundamental component that influences combustion efficiency and overall engine power. Made from high-strength steel, it is engineered to withstand the extreme pressures and temperatures within the combustion chamber, ensuring durability over many service intervals. Its precise height and outer diameter are critical for proper fitment and sealing within the cylinder head. The piston’s robust construction minimizes wear and deformation, maintaining compression and preventing power loss. It also plays a role in heat dissipation, helping to keep the engine operating within safe temperature ranges. Proper piston function is essential for smooth engine operation and fuel economy, directly impacting performance and emissions.
