Answer:

Explanation:
,K=1.35
Clearance is 8%.
Heat added=15 KJ
We know that compression ratio 
r=13.5



We know that efficiency of otto cycle




W is the work out put and Q is the heat addition.

W=8.4 KJ
We know that Work =Mean effective pressure x swept volume.
Here swept volume 


Noe by putting the values
Work =Mean effective pressure x swept volume.
