A V-S four-stroke petrol engine is required to gist 186.5 kW at 4400 rev imin. The brake thermal efficiency can be assumed to be 32% at the compression ratio of 9/1. The air-fuel ratio is 12/1 and the volumetric efficiency at this speed is 69%. If the stroke to bore ratio is 08. determine the engine displacement required and the dimensions of the bore and stroke. The of the fuel is 44 200 Wks, and the free air conditions are 1.013 bar and 15° C.
