What are the main differences between 4-stroke and two-stroke engines? A petrol engine works on otto-cycle the pressure, temperature and volume of air at the beginning of the cycle are 0.93 bar, 38oC and 0.028 cu.m. The pressures at the end of compression and at the end of heat addition are 7.87 bar and 21.97 bar. If there are 250 working cycles per minute, find the ideal power developed by the engine. Also find the efficiency of the cycle.
