A two-cylinder 250 cm^3 displacement motorcycle engine that operates on an ideal Otto cycle at 4500 RPM. The compression ratio is 9. Air enters the engine at 100 kPA, 27 degree C and peak temperature is 2250 degree K. Determine:

a. the net work percylinder

b. the cycle thermal efficiency

c. the net power output

d. what is the cycle efficiency if a cold-air-standard analysis is used with the following values: R = 8.314 kJ/kmol-K, cp = 1007 j/kg-K, cv = 0.720 kj/kg-K?
