4. A BMW with 4-stroke 2.0 L Twin Turbocharger 4-cylinder in-line engine is connected to an engine dynamometer which gives a torque reading of 350 Nm at 3800 rpm. The engine is running with volumetric efficiency of 118% and petrol RON95 (C7H₁7) is used as the combustion fuel. At the engine speed of 3800 rpm, the intake air pressure and temperature both are 155 kPa and 38°C. Given the gas constant value R-0.287 kJ/kgK. Calculate: a) Fuel mass flow rate of the engine. b) Brake specific fuel consumption of the engine at 3800 rpm in g/kW.hr
