A single-cylinder, four stroke research engine
operates on Otto cycle. The specification
of the engine is shown as below:-
Displacement volume of the cylinder = 560 cm3
Clearance volume of cylinder = 70 cm3
Minimum temperature = 200°C
Minimum pressure = 200 kPa
Net work output = 1000 kJ/kg
Sketch the process on a P-V diagram and by using constant specific
heat at room
temperature, determine:
1) the temperature and pressure at each process,
2) the thermal efficiency of the engine, and
3) the Mean Effective Pressure (MEP).
