The cylinder diameter of a $2-$stroke single$-$cylinder engine operating according to the air standard diesel cycle is $100$mm dry and $120$mm max. The speed is $3000$ rpm$,$ the compression ratio is $15\mathrm{.}4,$ the injection of fuel ends at $5\%$ of the stroke volume. The turbocharger works independently of the engine. Considering that the isentropic efficiency of the compressor and the turbine is $90\%,$ the pressure ratio of the compressor is $2,$ the exit pressure of the exhaust gases expanding on the turbine blades from the turbine is $200$ kPa, the temperature of the air absorbed by the compressor is $27\backslash$deg C$,$ and the pressure is $100$ kPa;

a$.$ Wc$=?$ Wt$=?$

b$.$ Enginepower?

c$.$ Engine efficiency?

d$.$Turbine net output power

e$.$Total output shaft power

f$.$ Find the actual exit temperature of the exhaust gases from the turbine?
