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.

Product Features:

• OE Quality
• Optimized for strength
• Heat and corrosion resistant
• Chromium plated or nitrided
• Stem optimized to resist wear

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 Crankshaft Position Sensor plays a vital role in your engine’s operation; to determine the exact position of then engine’s crankshaft to the ECM. The ECM then uses this information to determine fuel and spark timing or engine misfire detection. A failed sensor can result in a check engine light, failure to start, intermittent stalling, or misfire. NTK Crankshaft Position Sensors are a premium quality product with outstanding support and leading innovation bred from our OE heritage.

Product Features:

• THE NTK DIFFERENCE: Enhanced, robust circuit board traces and precision-wound coated-copper windings increase durability, longevity and performance
• OE QUALITY: Designed to meet or exceed OE specifications, fit, form and function to ensure proper position and/or rotating speed of the crankshaft
• EXTENSIVE TESTING: 100 percent thermal shock and vibration tested for best in class performance and reliability in the most extreme conditions
• PRODUCT ENGINEERING: Premium seals prevent leaks or corrosion, while optimized magnet size and strength ensures precise, consistent signal output

ARP only uses premium grade 8740 alloy and a proprietary ARP2000 alloy that are rated for superior to “aircraft” quality alloy steels. Secondly, each stud is placed vertically into special racks and precisely heat-treated to 200,000 psi for the 8740 material and 220,000 psi for the ARP2000 material. This procedure ensures complete heat penetration and the results are far superior to those lesser quality studs from other manufacturers who just dump pieces in a basket and hope for the best.

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

Product Features:

• Maximum durability
• High wear and corrosion resistance
• Excellent heat-conducting capacity
• Optimal fit
