A four-stroke, four-cylinder engine has a Bore= 2.7 inches; stroke=4.2 inches and compression ratio: 8.3:1

Determine: a) the total engine volume VBDC for all cylinders (cubic inches), b) the mass of air contained in the engine assuming ambient conditions of 540 R and 14.7 psia.

Assume this vehicle’s consumption rate is 2 Gallons/hour and crankshaft speed of 4000 RPM, where gasoline has a heating value of 122,000 Btu/gallon. Determine a) the fuel combustion energy per thermodynamic cycle (Btu), b) specific heat input per thermodynamic cycle (Btu/lbm).
