The Influence of Exhaust and Scavenging Time Area Design on the Engine Performance in the Poppet Valve Uniflow Two-Cycle Engine : Part 2, Influence of Exhaust and Scavenging Time Area Design on the Engine Performance

抄録

The influence of the design parameters of exhaust and scavenging time ares on the engine performance was calculated, assuming various operating conditions and various characteristics for the engine, blower, and so forth. Some general principles and suggestions in determining optimum exhaust and scavenging time areas were shown. In addition, the peculiarity and restriction of exhaust and scavenging time area designs are briefly discussed for the poppet valve uniflow type engine, as compared with the opposed-piston type and the loop scavenging type engines.
