|---|---|
| Heat addition process in an Otto cycle is a constant volume process . | Heat addition process in a Diesel cycle is constant pressure process . |
| Otto cycle is used in petrol engines . | Diesel cycle is used in diesel engines. |
| 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 cycle. |
| Practically , Otto Cycle is less efficient because of the problem of knocking . | Diesel Cycle is practically more efficient due to higher compression ratios. |
