SI Automobile engine operates at WOT on a four-stroke air standard Otto Cycle at 3000rpm. Fuel is isooctane with AF = 14, a heating value of 49,554 KJ/kg. The engine has compression ratio of 7.4:1 and a stroke to bore ratio of S/B = 1.128. At the start of the compression stroke, conditions in cylinder combustion chamber are 1 bar and 671.67 Rankine. It can be assumed that there is 4% exhaust residual left over the previous cycle. This cycle consists of 4 cylinder with 3.1 Liter Sl automobile engine. Use k = 1.332, Cv = 0.821 KJ/kg.K. Heat added is 2.226 Kilojoules. Determine: Bore of the cylinder in centimeter and Stroke of the cylinder in centimeter.

Transcribed Image Text:SI Automobile engine operates at WOT on a four-stroke air standard Otto Cycle at
3000rpm. Fuel is isooctane with AF = 14, a heating value of 49,554 KJ/kg. The engine
has compression ratio of 7.4:1 and a stroke to bore ratio of S/B = 1.128. At the start of
the compression stroke, conditions in cylinder combustion chamber are 1 bar and
671.67 Rankine. It can be assumed that there is 4% exhaust residual left over the
previous cycle. This cycle consists of 4 cylinder with 3.1 Liter Sl automobile engine. Use
k = 1.332, Cv = 0.821 KJ/kg.K. Heat added is 2.226 Kilojoules. Determine: Bore of the
cylinder in centimeter and Stroke of the cylinder in centimeter.
