In order to obtain the limiting delivery ratio curve, the relationships between the delivery ratio and the engine speed were investigated on crankcase-scavenged 2-stroke cycle engines by varying through wide limits the effective angle-areas Fia(e) of the inlet ports.It was found that the mean inlet Mach number Mim, already reported by the authors using 4-stroke cycle engines, showed well the characteristics of the limiting delivery ratio, and when Mim approached a limiting value the delivery ratio decreased hyper-bolically with an increase in engine speed.
