A four-cylinder engine has a bore of 90mm and a stroke of 100mm. The clearance volume of each cylinder is 0.065 L. Assuming compression starts at the bottom of the stroke, determine:

Question

(a) the capacity of the engine
(b) the compression ratio of the engine

Answer 1

you know that for one cylinder, v = πr^2 h

so, plug in your numbers and add .065L (as mm^3)
