# Length of stroke, cylinder bore, clearance volume, thermal efficiency

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

#### Solution Preview

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
