(8190046) -4- 71400(E)(N29)T QUESTION 2 A single-cylinder engine operating on the diesel cycle principle has a volumetric expansion ratio of 6,25:1 and a volumetric compression ratio of 15 : 1. The piston has a diameter of 89 mm and a stroke length of 90 mm.-The compression index, Nc is 1,32, while the expansion index, nz is 1,3. The temperature at the beginning of compression is 28 °C. Assume Cy for the gas as 1,005 kikg.K and C, as 0,718 kJ/kg.K. ash 5 . Calculate: ng 24 The swept volu (2) 2.2 (2) 23 (1) 24 (1) 25 (4) 26 (1) 277 (2) 28 » ) 29 (3) [20] Downloaded from hlayiso.com
