A 4.8-liter, spark-ignition, four-stroke cycle, V8 industrial engine operates 24 hours per day for five days at 2000 RPM using gasoline with A/F- 14.6. The engine has a volumetric efficiency of 92%, a brake fuel conversion efficiency of 30%, and a bore / stroke relationship as B- 1.06S. Assuming the intake temperature and pressure are 300K and 100 kPa, respectively, calculate: as B- pressure are 300K and 100 a. Stroke length (cm). b. Average piston speed (m/s). c. Number of times each spark plug has fired. d. Mass flow rate of air into engine. e. Mass flow rate of fuel into the engine f. Brake power of the engine g. Brake torque of the engine.
