Aspark ignition engine is to be modeled using fluid, air, is at 95 kpa and 290 k before compression. the compression ratio is 9 and the maximum temperature is 2000 k. for the calculations below use variable specific heats an ideal otto cycle. the working a) find the pressure and temperature at the end of compression (kpa, k) b) find the required heat input into the cycle on a specific basis (kj/kg) c) find the net specific work from the cycle (kj/kg) d) find the cycle thermal efficiency.
