Development Materials

Piston rings are key components in highly loaded two- and four-stroke industrial engines. As one of the leading piston ring suppliers for large bore engines, Federal-Mogul Powertrain continuously improves the functional surfaces of these components. New technologies are being used to develop high-performance functional surfaces with optimized properties to meet the challenges of current and future engine development trends and fuels.

Requirements for Large Piston Rings and Industrial Engines

Modern Large Bore Engines (LBEs) have to meet similar operating requirements as automotive engines and must survive in a highly competitive environment. While the issue of environmentally friendly resource efficiency is becoming increasingly important, operating costs are the most significant development driver. At the same time, four-stroke engines are becoming more flexible, mainly in terms of fuels and operating cycles, while two-stroke engines are subject to heavy cost pressure and...
