Increasing air charge of crankcase scavenged two-stroke cycle engines is essential for improved performance; accordingly, crankcase volume and dimensions of inlet system were experimentally investigated in order to fully utilize dynamic effect of both exhaust and inlet systems with view toward increasing delivery ratio; to achieve full utilization of effect of inlet system, it was found that time-area of inlet port should be far larger than that considered for usual engine; drop in delivery ratio caused by increasing crankcase volume can be fairly well compensated for by tuning exhaust and inlet systems.
