Question

An Engine-working on Otto cycle has a volume of 0.45 m3 pressure 1 bar and temperature
300,C at the beginning of compression stroke. At the end of compression stroke, the pressure
is 11 bar and 210 KJ of heat is added at constant volume. Determine (1) Pressure, temperature
and volumes at salient points in the cycle." (lI) Efficiency​

Answer 1

Answer:

An engine working on Otto cycle has a volume of 0.45 m3, Pressure 1 bar and temperature 30 C at the beginning of compression stroke. At the end of compression stroke, the pressure is 11 bar. 210 kJ of heat is added at constant volume. Determine: i) Pressure, Temperature and volumes at salient points in the cycle. ii) Percentage clearance iii) Efficiency iv)Net work per cycle v) Mean effective pressure vi) Ideal power developed by the engine if the number of working cycles per minute is 210. Assume the cycle reversible
