diesel cycle exercise 1

An internal combustion engine on the diesel cycle principle has a clearance volume of 0,00041 m3, a piston diameter of 180 mm and the stroke length of 250 mm. Fuel is cut off at 20 mm after TDC on the return stroke. The pressure and temperature after polytropic expansion is 400 kPa and 1 150 K. The compression and expansion index is 1,35 and 1,28 respectively. Take R as 0,288 kJ/kg.K Calculate: 3.4 The swept volume and cylinder volume in m? » 5 - (4) 3.2 The volume after constant pressure heat addition in m* ere | (3) Bs The lowest and highest pressure in kPa “8 a (4) 3.4 The work done in kd/cycle ‘ r J (5) 3.5 SS SIN ce me eee aw [20]
