A four-cylinder spark-ignition engine has the following dimensions: bore = 680 mm and a crank radius = 375 mm. If the compression ratio is 8:1, determine the (i) stroke length (ii) swept volume (iii) cubic capacity (iv) clearance volume and (v) total volume. If the volumetric efficiency is 80%, determine the (vi) actual volume of air aspirated/stroke in each cylinder.

A four-cylinder, four-stroke, 2.2-L gasoline engine operates on the Otto cycle with a compression ratio of 10. The air is at 100 kPa and 60^∘ C at the beginning of the compression process, and the maximum pressure in the cycle is 8 MPa. The compression and expansion processes may be modeled as polytropic with a polytropic constant of 1.3. Using constant specific heats at 850  K, determine (a) the temperature at the end of the expansion process, (b) the net work output and the thermal efficiency,
