QUESTION 1 a) With the aid of a table, list five (5) differences between 2-stroke and 4-stroke engine. [CO1/PO1/C2] (5 marks) b) 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 = 540 cm³ Clearance volume of the cylinder = 60 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: i) the temperature and pressure at each process, ii) the thermal efficiency of the engine, and iii) the Mean Effective Pressure (MEP).
