You have an engine you wish to model using an ideal otto cycle. the engine has 1.5 l displacement (vd = vmax − vmin) and compression ratio of 10.5: 1. at a low load you know 0.55 kj of energy is added to the engine, and the in-cylinder pressure and temperature are 50 kpa and 320 k at the start of the compression stroke. using the air-standard assumptions with variable specific heats and r=0.287, what are the peak cycle temperature and pressure? what is the cycle efficiency, and what would the efficiency of a carnot cycle operating between the same temperature limits be? what is the mean effective pressure (mep) at this operating condition?
