A gas engine has a swept volume of 300 cm3 and clearance volume of 25 cm3. Its volumetric efficiency is 0.88 and mechanical efficiency is 0.90. The volume of the mixture taken in per stroke is

A.
248 cm3
B.
252 cm3
C.
264 cm3
Answer
D.
286 cm3

Answer: Option C

Solution

Answer: Option C
Solution:
Actual volume = swept volume × volumetric efficiency
= 300 × 0.88
= 264 cm3
