Lightweight, thermally expanded aluminum alloy pistons with piston pins that float in the piston bosses are offset to the pressure side and are mounted on forged steel connecting rods. The pistons are classified into one of four classes - 1, 2, 3 or 4. The pistons are marked so that they are correctly oriented in the cylinders.; The "arrow" should point towards the front of the engine.
The V6 petrol engine uses forged steel I-beam connecting rods. The piston pin provides a fixed fit for the upper connecting rod head. The lower heads are horizontally divided.
Selected bearing shells with two thickness classes, nominal and reduced size 0.25 mm, control the diametrical clearance of the lower connecting rod heads. The upper and lower bearing shells of the lower heads have a simple shape without installation protrusions.
Each piston is equipped with two compression rings and an oil scraper ring. The upper compression ring has a nitrided surface, which is obtained by diffusing nitrogen into the surface layers of low-carbon steel. The resulting nitrides provide increased hardness. The second compression ring is chrome-plated. The oil scraper rings have upper and lower stainless steel guide elements and built-in expansion rings.
