Need help with this homework problem. At the beginning of the compression process of an air standard Otto cycle, p1 = 1 bar, T1 = 300 K. The maximum temperature in the cycle is 2250 K and the compression ratio is 9.8. The engine has 4 cylinders and an engine displacement of Vd = 2.1 L. Determine per cylinder: a) the volume at state 1 in L.b) the air mass per cycle.c) the heat addition per cycle, in kJ.d) the heat rejection per cycle, in kJ.e) the net work per cycle, in kJ.f) the thermal efficiency.g) the mean effective pressure, in bar.h) Develop a full exergy accounting per cycle, in kJ. Let T0 = 300 K, p0 = 1 bar.i) Devise and evaluate the exergetic efficiency for the cycle.

The displacement volume of an internal combustion engine is 2.15 liters. The processes within each cylinder of the engine are modeled as an air-standard Diesel cycle with a cutoff ratio of 2.5. The state of the air at the beginning of compression is fixed by p1 = 1.6 bar, T1 = 325 K and V1 = 2.36 liters. If the cycle is executed 2100 times per min, determine:d) the power developed by the engine, in kW,e) and the thermal efficiency.
