Q) A single-cylinder two-stroke SI engine has 8 cm diameter bore and 10 cm stroke. The compression ratio is 8. The cxhaust port opcns 60° beforc BDC and closcs 60° after BDC. The air/fucl ratio is 15.1. The temperature of the mixture cntering into the cngine is 300 K and the pressure in the cylinder at the time of closing the exhaust port is 1.05 bar. Take R for the mixture = 290 J/(kg K). Air supplied to the engine is 150 kg/h. The speed of the engine is 4000 rpm, Considering the effective stroke, calculate the scavenging ratio, the scavenging efficiency and the trapping efliciency.
