[#87] An engine has a clearance volume of 100 cm 3 and a swept volume of 800 cm 3 . The compression ratio is
Correct Answer

(C) 9 : 1

Explanation

Solution: $$eqalign{
& { ext{COMPRESSION RATIO}} cr
& = frac{{{ ext{CLEARANCE VOLUME}} + { ext{SWEPT VOLUME }}}}{{{ ext{CLEARANCE VOLUME}}}} cr
& = frac{{100 + 800}}{{100}} cr
& = 9:1 cr} $$
