TURBOCHARGERS FOR TRACTION DIESEL ENGINES

M Wehrlin

Open publisher page 0 citations

Abstract

By using turbochargers the power output of a diesel engine can be increased to between 2.5 and 3 times that of the naturally aspirated engine. Since the power output determined for a definite type of engine, as well as the limits imposed on the overall dimensions of the locomotive, call for relatively small engines with high outputs, this accounts for the importance of the turbocharger in this field of application. The author deals with the problems that had to be solved during development of the turbocharger, to enable it to satisfy the requirements of the railways.
