| Its engines result in lesser thermal efficiency | Its engines result in higher thermal efficiency |
| It has a larger ratio in terms of power to weight | It has a lesser ratio in terms of power to weight |
| It generates more smoke and shows less efficiency | It generates less smoke and shows more efficiency |
| Requires more lubricating oil as some oil burns with the fuel | Requires less lubricating oil |
| Due to poor lubrication, more wear and tear occurs | Less wear and tear occurs |
| Engines are cheaper and are simple for manufacturing | Engines are expensive due to lubrication and valves and are tough to manufacture |
