Mechanical Validation: An Integral Part of Medium Speed Diesel Engine Development

A comprehensive mechanical testing program was part of the development of the Diesel engine for the GEVO locomotive family. The test program has been developed under consideration of the demands of a railroad application. The program included both fired engine and component rig testing. Component rig tests were used to validate major components early in the design stage. Engine testing included measurements to validate the CAE models and allow detailed experimental development of components and subsystems. Several endurance runs have proven the reliability of the new engine.
