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.

Engine Development

The use of electronic recording equipment now covers development, production, and service problems. Previously fuel injection characteristics and gas exchange pressures were the only parameters normally indicated. Today, however, owing to the demand for greater power outputs, a much wider range of parameters are studied electronically. The success of engine development and production relies upon the ease and accuracy with which engine performance can be measured. The historical development of engine indicating techniques used by the authors' company and the existing measuring accuracies are discussed. Various tables outline the individual and overall errors that were obtained using a wide range of transducers and associated equipment. The need for correct calibration procedures is emphasized throughout, and some of these procedures with their standardizing equipment are included in the paper.

Engine Development

In recent years intensive development of reciprocating internal combustion engines has led to progressively higher ratings with improved thermal efficiency and an ability to operate successfully on poorer quality fuels. Rising fuel costs have also led to an increasing interest in alternative fuels, and this in turn has promoted the design and development of engines capable of burning a variety of gases. The paper describes the design performance features and recent development achievements of a range of medium-speed gas-fed reciprocating engines with a capability to burn a range of gaseous fuels from natural gas down to synthetic or by-product gases with low calorific values of 4.85 MJ/m3(n).
