5. Consider a 4-stroke, 4-cylinder spark ignition engine. The engine has the following specifications Total Displacement Volume-2.4L (0.0024 m) Stroke = 103 mm Connecting rod length - 150 mm Compression ratio= 10 IVO -15Â°BTDC IVC-30Â°ABDC Spark = 12Â°BTDC At the peak torque operating set point the following are measured: Engine Speed = 3000 rpm Torque - 250 Nm Brake specific fuel consumption = 300 g/kW hr The engine operates stoichiometrically on gasoline. At this rated torque condition, find: a) Brake power (kW) b) Brake fuel conversion efficiency c) The engine volumetric efficiency using a reference density of 1.18 kg/m d) Instantaneous piston speed at the spark timing location (m/s) e) The clearance volume in one cylinder (cm).
