Genuine BMW 2002 Piston Ring

The cylinder pressure is protected by the Piston Ring of the BMW 2002. Therefore, the active four cylinders can effectively convert combustion force into smooth wheel motion. The Piston Ring, which sits between the piston and cylinder wall, seals hot gases, sweeps excess oil downwards, and transfers heat from the piston crown to cooler block metal, which helps in maintaining power high and keeping oil consumption low. The early models applied Piston Ring bands made of heavy cast iron with standard thickness. However, the performance update in 2002 applied thinner steel or ductile iron Piston Ring sets as thin as 1 millimeter on the top groove, coated with plasma moly or hard chrome for durability. This contemporary Piston Ring design tightens up tolerances without compromising on toughness. By employing a thinner design, the ring is able to flex more easily to accommodate slight bore irregularities, which enhances sealing while reducing friction and mechanical losses that can otherwise extract nearly one quarter of engine energy. Each piston still bears a well-known three ring stack, two for compression and one for oil control. But the overriding engineering evolution across the BMW 2002 line is mainly in materials and dimensions, showing continued BMW focus on efficiency.
