Goetze OE piston rings for gasoline and diesel engines, are developed for automobile, light commercial vehicle and heavy-duty applications, come in a wide range of sizes, include the first ring sets introduced for Euro4-compliant engines. The end gap can be a straight cut, angled cut or gas tight type for improved sealing. Radial pressure distribution greatly influences ring performance therefore we modify the pressure distribution according to the individual application. The wear-resistance and running-in behavior of the outer ring surface is defined by selecting from various coating options, which include the high-performance electroplated, thermally sprayed and PVD coatings. Goetze modern oil control rings scrape off oil from the cylinder wall, leaving just the required amount for lubrication. The running surface is the contour of the ring facing the cylinder surface. The objective of this running surface profile is to create a lubrication slot with a hydrodynamic film which the piston ring can slide on without touching the other surface. An optimized asymmetrical-barrelled running surface ensures low lubricant consumption even after a very long running time. Goetze piston rings have anti-scuffing properties that promote smooth engine operation, reduced oil consumption and long engine life. In addition, the Goetze process helps prevent materials from detaching and cracking and aids in environmental protection

Glyco advanced engine bearing technologies withstand heavy loads and cope with the increasingly challenging conditions of modern, environmentally-friendly engines. Glyco is the world’s largest manufacturer of OE-quality bearings. Every year, our engine bearings are fitted on more than 10 million engines around the world – from small bore engines to heavy-duty commercial vehicles and stationary engines. Driven by the need to reduce CO2 emissions, today’s engines extract more power from less fuel. Due to the increased temperature and load, conventional bearings struggle to cope. Thanks to over 100 years of innovation, Glyco provides bearings with advanced metallurgy that can withstand these challenges. Federal-Mogul invented Glyco Sputter Bearings with twice the service life of conventional bearings. Glyco developed G-188, the first intelligent bearing material, and were also first to launch a full lead-free material portfolio. Recent innovations include the highly durable Glyco IROX bearing shells, which address the challenges of hybrid, stop-start and downsized engines.

The cooling of high-load motor oils by oil coolers or the guarantee of an almost constant temperature spectrum brings considerable advantages. Oil change intervals are extended and the engine service life is increased. A basic distinction is made between air-cooled and coolant-cooled types. Depending on requirements, this latter type can be installed in the coolant box or engine block or attached externally to the engine, gear, cooling module or oil filter housing. Behr’s latest design is a compact and powerful stack-disc oil cooler. Since it manages without coolant housing and is made completely of aluminum, its outstanding features are its low weight and design space requirements.

Meets or exceeds OE specifications
Manufactured using advanced materials

TRW Engine Components is a recognized developer of valves and valve train components. A wide range of materials and material combinations are used to meet the engineering requirements in the different engine applications. Materials vary from ferritic martensitic steels (intake valves) and austentic CrMn based steels to extreme heat and corrosion resistant Nickel base super alloy for exhaust valves. To improve wear and corrosion resistance, valves can be chromium plated or nitrided. These coatings are used to improve the compatibility of the valve stem surface to the valve guide material. If necessary, exhaust valves (and in some cases also intake valves) can be hard-faced. In hard-facing, a more heat and wear resistant material is welded to form the valve seat. Seat hard-facing extends the valve life significantly.
