Ceramic Matrix Piston Rings

Cks has a crack network filled with aluminum oxide ceramic particles giving significantly lower wear rate and scuff resistance compared to hard chromium.
Ceramic matrix piston rings. Wear rings guide the rod and piston to prevent uneven wear and optimize seal performance. A ceramic fiber reinforced aluminum matrix composite has been developed that has excellent wear resistance seizure resistance against cast iron good thermal conductivity and high strength at elevated temperatures by strengthening top land and top ring groove of piston with the aluminum matrix composites a newly designed diesel engine attained excellent performance without sacrificing. Regardless of engine type bore size or ring thickness we carry all of the piston rings and piston ring sets you and your vehicle need including piston rings from industry leaders like sealed power wiseco total seal mahle je pistons speed pro and many more. A heat resistant thermally stable ductile piston ring for an internal combustion engine having a structure comprised at least partially of fiber reinforced ceramic matrix composite frcmc material.
Head seals are a more reliable alternative to the standard o ring backup ring combination they resist twisting. The wear response of ceramic matrix nano composite coatings in simulated piston ring cylinder wall test environments k l. High tem perature resistance and hardness with those of a metal. Cermet coated piston rings cermet is a composite part ceramic part metal material.
The frcmc material includes a polymer derived ceramic resin in its ceramic state and fibers. It combines the best properties of a ceramic i e. A piston ring is a split circular shaped ring that fits into a groove on the outer diameter of a piston to form a seal between the piston and the cylinder wall. When the air and fuel mixture ignite in each cylinder the ring must seal to the cylinder.
Goetze cks piston rings for 4 stroke large bore engines cks was developed specifically for piston rings in the top groove in highly rated diesel engines. Ened and will need machining before new rings can be run in. The ceramic portion of the material for the most part provides the heat resistance of the frcmc. Its function is to maintain proper combustion gas compression control the amount of lubricating oil to the pistons and to assist in heat dissipation from the piston to the cylinder.
Rod seals maintain the pressure inside cylinders and prevent fluid from leaking out. Rod wipers scrape dirt dust and moisture from the rod preventing contamination inside your cylinder. The piston rings have three major tasks to ensure the engine makes consistent power efficiently. Dearnley a a school of mechanical engineering university of leeds leeds ls2 9jt uk a series of piston rings with surface coatings of alumina matrix nano composite materials have been.
Shop summit racing now for low priced fast shipping on the parts that will. First of all the ring must seal each cylinder effectively without fail for thousands and sometimes hundreds of thousands of miles before replacement.
