Vibration Model

In this article, a coupling model of shafting torsional vibration with advanced injection angle is proposed to study the effect of advanced injection angle on shaft torsional vibration. Using Simulink, a model shaft system of a 4190ZL_C medium-speed diesel engine is created to study the effect. The proposed coupling model, the traditional simulation method and the test are conducted on the torsional vibration of the 4190ZL_C medium-speed diesel engine, separately. The results show that the spectrum from the coupling vibration model is more abundant than from the traditional vibration model. Hence, considering the effect of advanced injection angle on shaft torsional vibration, the proposed coupling model can improve the modeling accuracy of shaft torsional vibration. It provides a new approach in engine design.

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.
