    The four cylinders of a four-stroke spark-ignition petrol engine have a total capacity (swept volume) of 1200 cm^3.

    The stroke-bore ratio is 1.1, the compression ratio is 9.5 and the ratio of the specific heats (y) is 1.41.

    Determine:
    (a) the length of stroke
    (b) the cylinder bore
    (c) the clearance volume per cylinder in cm^3
    (d) the thermal efficiency

    Answer:
    CR = (CV + SV) / CV

    SV= Swept volume
    CV= Clearance Valoume
    CR= Compression Ration

    ( C)_______________________
    note: the total swept volume of all 4 cylinders given ...

    Solution Summary
