| 11. | An additional piston ( in its own cylinder ) is shared by the two Otto cycle cylinders.
|
| 12. | In thermodynamics, heat engines are often modeled using a standard engineering model such as the Otto cycle.
|
| 13. | The Otto Cycle engine was eventually adopted to run on Ligroin and eventually gasoline, and many gases.
|
| 14. | In contrast, the idealized Otto cycle of a gasoline engine approximates a constant volume process during that phase.
|
| 15. | Notably, the combustion takes place at constant pressure, rather than with the Otto cycle, constant volume.
|
| 16. | The formula is more complex than the Otto cycle ( petrol / gasoline engine ) relation that has the following formula;
|
| 17. | The exhaust from the Otto cycle cylinder is directed into the shared cylinder, where it is expanded generating additional work.
|
| 18. | In the ideal otto cycle this expansion is assumed to be adiabatic, which means that no HEAT transfer takes place.
|
| 19. | Furthermore, the ideal Otto cycle formula stated above does not include throttling losses, which do not apply to diesel engines.
|
| 20. | Heat flows into the Otto cycle through the left pressurizing process and some of it flows back out through the right depressurizing process.
