a. Define the following terms,
(i) specific work transfer
(ii) specific air consumption
(iii) work ratio
(iv) swept volume
b. Derive the formula for the meaneffective pressure of the Ottocycle
c. An engine of 200 mm bore and 315 mm stroke works on Otto Cycle. The clearance is
3O
0.00251 m . The initial pressure and temperature are 1 bar and 65 C. If the maximum
pressure is limited to 35 bar, calculate the following,
