A student is tasked to investigate the internal parts of an internal combustion engine. He/she is not allowed to dismantle the engine. Assist the student in the investigation using information as follows: Cylinder 4 4 Stroke Air-fuel ratio Stroke-bore ratio 15 1.1 Brake power 40 kW @ Fuel calorific value 44,000 kJ/kg 4000 rpm Volumetric efficiency 90% Brake thermal 32% efficiency Compression ratio 9 Air density 1.181 kg/m3 Determine (in units of): (a) Fuel flow rate (kg/s) (b) Mass of air per cylinder (kg) (c) Engine capacity (cm³) (d) Cylinder bore and stroke length (cm) (e) Average piston speed (m/s) (f) Clearance volume of each cylinder (cm³) (3 marks) (3 marks) (4 marks) (4 marks) (3 marks) (3 marks)
