The diesel system shown in the figure consists of a multicylinder reciprocating diesel engine, a turbocharger (with a compressor C and turbine T, mechanicaily connected to each other), an intercooler (I), and a power turbine (T,) which is geared to the engine drive shaft. The gas and fuel flow paths and the gas states at the numbered points are shown. You can assume that the specific heat at constant pressure c, of the gas throughout the entire system is 1.2 kJ/kg. K and y = cdc, = 1.333. The engine operates at 1900 revjmin. The fuel has a lower heating value of 42 MJ/kg of fuel,
