EFFECT OF THE VARIATION OF EXHAUST AND FUEL INJECTION TIMING ON THE GENERAL MOTORS DIESEL ENGINE MODEL 1-53X3

Abstract

The GM Diesel Model 1-53X3 is a single-cylinder, two-stroke-cycle engine rated at 30 hp at 3000 rpm. It was developed with both two and four exhaust valve cylinder heads. Variable exhaust and injector cam shaft gears have been added to facilitate changes in timing. The purpose of this investigation was to determine the effects of the variation of exhaust and fuel injection timing on engine performance. A piezoelectric pressure pickup was used to obtain oscilloscope displays of pressure versus crank angle which were photographed. Injection from 20 deg BTC to 5 deg BTC for three exhaust timing configurations have been investigated for each head. Engine performance data under these conditions are presented and discussed. The engine as instrumented lends itself to a variety of student exercises and demonstrations.
