Diesel Engine Development for Low Emission Rail Traction Application

This paper describes the evolution of a family of modern four stroke high power density engines, the Ruston RK215 series, which has been developed to meet the specific needs of heavy duty rail traction application including the current EPA and UIC (European) emissions legislation. It discusses the extensive experience of Ruston in powering various locomotives including recent applications in overseas markets.

The methodology adopted in the base engine design, to achieve high reliability and good component life is discussed with methods of validation and risk analysis during the design and development program. Specific reference is made to an emissions research program to ensure the engine will comply fully with future legislation.
