The Otto cycle was given by German scientist Otto, in 1876 and Diesel cycle was discovered by Dr. Rudolph Diesel in 1893.In Otto cycle the heat addition is takes place at constant volume where as in diesel cycle heat is added at constant pressure.Petrol engines work on Otto cycle and diesel engines work on diesel cycle.In Otto cycle at the time of heat addition, the piston is at TDC where as in diesel cycle when the piston is in backward stroke, the heat addition begins and last at a portion of piston stroke.
