GM Diesel's Additional Engines— NEW VEES AND In-lines 590267

THIS PAPER describes two new series of diesel engines produced by Detroit Diesel — a smaller 53 Series and the V-71 Series.
The V configuration was chosen for all the new engines (except the very small 2-, 3-, and 4-cyl 53 Series) because of its inherent size and weight-saving characteristics. For example, the new 6V-71 engine is 40% shorter and 15% lighter than the in-line 6-71 engines.
Development of the Series 71E engine to date has yielded cleaner exhaust with equal power, improved fuel economy, longer life, and superior altitude performance.
The authors present design features of both series of engines.
