Q3:A small truck has #cylinder ,4 liter compression ignition engine that operates on ir standard Dual cycle with air fuel ratio of 16:1, the compression ratio is 17 and the cylinder diameter is 14.5Cm. At the start of compression stroke Ta=50'C and Pa=100 kpa .It can be assumed the half of the heat input is added at constant volume and halt at constant pressure Calculate: 1-Temperature and pressure at each state of the cycle. 2-Indicated thermal efficiency. 4:28 PM
