Pressure-time diagrams taken near the exhaust port of a 2-cycle engine provide valuable insight into the performance of the power unit. The optimum phasing of the scavenging and plugging pulses are then observable from these diagrams. Unsteady flow gas dynamic theory, with the arithmetic handled by a digital computer, will predict the phasing and amplitude of these important exhaust pulse reflections at any engine speed, in any exhaust system, for any engine. Design of such an exhaust system for a projected engine unit or an existing design becomes a real possibility, thus saving valuable development time and money.Pressure-time diagrams taken near the exhaust port of a 2-cycle engine provide valuable insight into the performance of the power unit.
