Description: CP-Carrillo 3.642" / 92.50 mm Bore Piston Ring Set For BMW M30B35 Not compatible with OEM pistons. Confirmed Fitment: CP Pistons, Wiseco Pistons, JE Pistons. FITMENT :For BMW M30B35 PRODUCT DESCRIPTION :The principal function of the piston rings is to form a seal between the combustion chamber and the crankcase of the engine. The goal is to prevent combustion gases from passing into the crankcase and oil from passing into the combustion chamber. During the compression and power strokes, the compression ring seals the combustion gases and prevents blow-by. Although blow-by is not completely eliminated it is kept to an acceptable limit. During the compression and exhaust strokes the cylinder walls are lubricated with oil by throw off from the connecting rod bearings. Excess oil is wiped off by the piston rings. Not only does the oil ring have the responsibility of wiping the excess oil off the cylinder walls, but the job is also shared by all of the rings, leaving a fine layer of oil on the wall to provide lubrication for the following ring. CP-Carrillo offers the latest materials and coatings available to keep pace with the growing trends in engine technology. We offer a variety of materials and coatings for piston rings ranging in diameter – from Automotive and Diesel, to Powersport and Marine. Top RingThe top ring is a steel compression ring that has been gas nitride so that it is compatible with Nikasil and cast iron bores. This scuff resistant gas nitrided ring allows it to operate at maximum efficiency without blemishing up the bore. The nitriding ensures extended life and protection under extreme conditions. Second RingThe second ring is a cast iron with a taper underhook groove face. The THG ring acts as a wiper and pushes the oil back away from combustion. This type of ring allows you to run a lower tension oil ring. Oil RingThe oil ring is made up of two soft nitride rails with a low-tension expander. Because of the miniflex vent design; there is less friction on the cylinder wall, which increases the performance and efficiency of the engine. These ring sets are high strength and low tension, resulting in maximum sealing with minimum drag.
