. A turbocharged, three-cylinder, four-stroke cycle, 1.5-liter, multipoint port-injected SI engine using stoichiometric gasoline operates at 2400 RPM with a volumetric efficiency of 88%. The turbocharger has a turbine isentropic efficiency of 80% and a compressor isentropic efficiency of 78%. Exhaust flow enters the turbine at 770 K and 119 kPa, and exits at 98 kPa. Air enters the compressor at 27°C and 96 kPa, and exits at 120 kPa. Calculate: (a) Mass flow rate through the tubocharger compressor. [kg/see] (b) Mass flow rate through the turbocharger turbine. [kg/see] '- (c) Inlet air temperature at turbocharger exit. [0C] (d) Exhaust temperature at turbocharger exit. [0C]
