A two-stroke diesel engine with a displacement of 200cc, it has a compression ratio of 17 and a cut-off ratio of 2.5. At the beginning of the compression process, the air is at 50°C and 100 kPa. Using the cold air pattern assumptions. a) Determine the temperature at all points in the cycle. b) Determine engine work. Express the value in kJ/rot,

In a standard Diesel cycle, compression starts at the final ambient conditions of the addition of heat, conditions are 5.0MPA for pressure and 1750 ° C for temperature.  Using with specific heats evaluated at 300K.  Determine: a) The mean effective pressure, in kPa.  b) The thermal efficiency of the cycle.  c) The cut-off ratio.  d) The compression ratio.

An air-standard dual cycle has a compression ratio of 9.1 and displacement of Va= 2.2L.At the beginning of compression, p1= 95 kPa, and T = 290 K. The heat addition is 5 kJ, with one quarter added at constant volume and the rest added at constant pressure. Determine: a) each of the unknown temperatures at the various states, in K. b) the net work of the cycle, in kJ. c) the power developed at 3000 cycles per minute, in kW. d) the thermal efficiency. e) the mean effective pressure, in kPa.
