A turbocharged 2-liter direct injection diesel engine operates on a four-stroke cycle. At 2900 rpm and a bmep of 9.7 bar (full load), it is operating with a 22: 1 gravimetricair-fuel ratio and a brake specific fuel consumption of 230 g/kWh. The turbocharger is fittedwith a waste-gate to regulate the pressure ratio to 2.0. Use the compressor map attached,for which the pressure units are kPa, and the mass flow is grams per second, and the temperatureunits are Kelvin. The turbine entry temperature is 850 K, its pressure ratio is also 2.0,and the turbine isentropic efficiency is 0.75.The
A turbocharged 2-liter direct injection diesel engine operates on a four-stroke cycle.

The turbocharger is fittedwith a waste-gate to regulate the pressure ratio to 2.0. Use the compressor map attached,for which the pressure units are kPa, and the mass flow is grams per second, and the temperatureunits are Kelvin. The turbine entry temperature is 850 K, its pressure ratio is also 2.0,and the turbine isentropic efficiency is 0.75.The compressor entry conditions are 1 bar and 298 K, and you should assume the following thermodynamic properties:Specific heat capacity at constant pressure, cp (kJ/kgK) 1.01 for air and 1.12 for exhaust gas.Ratio of heat capacities, k=1.4 for air and 1.33 for exhaust gas
1). Stating any assumptions you make, calculate the brake power output of the engine, its volumetric efficiency (based on inlet manifold conditions), and the fraction of the exhaustgas that passes through the turbine.2). Suggest ways of increasing the bmep of this engine in order of increasing complexity, with an indication of the likely increase in output (and how this would be calculated).Comment on how other aspects of the engine performance would be affected.
