Medium Speed Diesel Engine Piston Rings

Kaydon manufacturers power piston rings, turbocharger seal assemblies and lower liner inserts for most models of EMD, General Electric and Alco medium speed diesel engines found in locomotives, workboats, and industrial/municipal power generation facilities. Since the inception of the diesel-electric locomotive in the 1940s, Kaydon has designed and produced diesel engine piston rings for the major OEMs and railroads worldwide. Through the years, Kaydon's OEM designs and specialty design ring sets have proven most effective in reducing oil consumption, blow-by and souping. This leadership position in solving the performance problems of the industry is why Kaydon continues to be the source for innovation in the face of ever-changing environmental requirements for diesel and gas fueled engines.

Reduced Emission Power Ring Set for Locomotive Engines

Kaydon's emissions control ring sets help reduce particulate emissions by reducing both initial and longterm oil consumption of locomotive engines. The Kaydon low emissions ring sets have been qualified to meet the EPA emissions regulations.

Improved EMD Turbocharger Seal Assemblies

Kaydon's improved EMD 645 and EMD 710 seal assemblies incorporate significant design features that maintain a positive side seal at temperatures up to 1200°F (649°C). This assembly reduces exhaust leaks, improves turbo efficiency, and can contribute to improved fuel economy in two-piece turbochargers found in locomotives, workboats and other applications. Engines equipped with this turbocharger seal assembly can comply with EPA regulations and eliminate costly downtime.
