COMPUTER PREDICTION OF POWER AND NOISE FOR TWO-STROKE ENGINES WITH POWER TUNED SILENCED EXHAUSTS

A research effort sponsored by Yamaha Motors, LTD. was undertaken to investigate exhaust system and exhaust silencing concepts for two-stroke engines. A complete one-dimensional gas dynamic computer program was developed for power-tuned exhaust systems. An overall engine-model has been developed for simulation of the internal gas dynamic behavior throughout the engine. This model includes the combustion and induction aspects of the engine cycle as well as a simplified exhaust system model. Engine power and torque can be predicted. Both analytical and experimental programs are described for simulation and testing of candidate mufflers and muffling techniques. /GMRL/
