A two stroke four cylinder ideal otto engine operates at 4800rpm. Air is taken in at 101 kpa and 20 Centigrade. The volume in each cylinder is 500 cm^3 before compression and 90 cm^3 after compression. If 2500 j/g of air heat is added.
Determine (a) Compression Ratio. (b) p,V and T at four corners (c) Entropy change during heat addition (d) Work cycle (e) Heat rejection (f) Power of engine (g) sketch p-V and T-s diagram?
