'''Otto Cycle''' | '''Diesel Cycle'''
Heat addition process in an otto Otto cycle is a constant volume process . |heat Heat addition process in an a diesel Diesel cycle is constant pressure process. Otto cycle is used in petrol engine engines . | Diesel cycle is used in diesel engineengines. For the same compression ratio the efficiency of Otto cycle is more than the diesel cycle . | For the same compression ratio the efficiency of diesel cycle is less than otto Otto cycle. Practically , Otto Cycle is less efficient because of the problem of knocking . | Diesel Cycle is practically more efficient due to higher compression ratios.
