A large V8 SI four-stroke cycle engine with a displacement of 4.6 liters is equipped with cylinder cutout, which converts the engine to a 2.3 liter V4 when less power is needed. At a speed of 1750 RPM the engine, as a V8, has a volumetric efficiency of 51%, a mechanical efficiency of 75%, an air-fuel ratio of 14.5, and produces 32.4 kW of brake power using gasoline. With cylinder cutout and operating at higher speed as a V4, the engine has a volumetric efficiency of 86%, a mechanical efficiency of 87%, and uses an air-fuel ratio of 18.2. Indicated thermal efficiency can be considered the same at all speeds, and assume combustion efficiency is 100%. Calculate: a. Mass flow rate of air into V8 engine at 1750 RPM (kg/s). b. Mass flow rate of fuel into V8 engine at 1750 RPM (kg/s). c. The BSFC as V8 at 1750 RPM (g/kW-hr). d. The engine speed needed as a V4 to make the same brake power as a V8 (RPM). e. The BSFC as V4 at the higher speed (g/kW-hr).
