Question

A six-cylinder engine, 5 liters 4 strokes supercharged, operating at 4300 rpm has a volumetric efficiency of 92 % (referred to the intake conditions, state 3). The compressor has an adiabatic efficiency of 90% and a mechanical efficiency of 85% in its link with the engine (see the figure below). The compressed air is delivered to the engine cylinders at 60°C and 1.85 bar (intake conditions). The ambient conditions are 19°C and 1 bar (at the inlet of the compressor). Take the gas constant 287 J/kg.K for air, the specific heat Cpair = 1.005 kJ/kg.K and the specific heat ratio k = 1.4 After-cooler 2 Engine P1 The temperature of air at the exit of the compressor is (K): Choose... + The mass flow rate of the air is (kg/s): Choose... + The rate of heat rejection from the after-cooler (intercooler) is (kW) Choose...
