COMPARISON OF COMPUTER PREDICTIONS AND EXPERIMENTAL TESTS FOR TWO-STROKE ENGINE EXHAUST SYSTEMS

The effect of exhaust system configuration upon performance of two-stroke engines is explored. Computer predictions of gas dynamic behavior in the exhaust pipes are compared to experimental results of real pipe tests. Predicted pressure, velocity and temperature histories at key points in the exhaust system explain the relative power differences for the test pipes. Predicted volumetric flow rates show the effectiveness of exhausting gases at larger pipe cross sectional areas in reducing noise output. /GMRL/
