Промежуточное поршневое кольцо, диаметр 146,05 мм Caterpillar 5M9053

An Intermediate Piston Ring sits in a groove machined on the piston body, positioned between the top compression ring (closest to the engine head) and the oil control ring (at the bottom). It is a slightly tapered or barrel-faced profile. The taper or barrel shape helps create a tighter seal as combustion pressure pushes the ring outward against the cylinder wall.Attributes:• Helps minimize blow-by by providing an additional barrier between the top compression ring and the oil control ring• Helps distribute the load on the cylinder wall and minimizes metal-to-metal contactApplications:An Intermediate Piston Ring acts as a secondary seal to prevent combustion gasses from leaking past the piston into the crankcase while also contributing to oil management within the engine.
