| 1. | This means the compression ratio is smaller than the expansion ratio.
|
| 2. | Its expansion ratio and ease of handling made it popular.
|
| 3. | Each engine is a Vulcain engine with reduced expansion ratio.
|
| 4. | The large expansion ratio requires a large cylinder volume.
|
| 5. | The expansion ratio after combustion still remains high.
|
| 6. | Diesel engines have a compression / expansion ratio between 14 : 1 to 25 : 1.
|
| 7. | This design provides higher fuel efficiency due to the higher overall expansion ratio of the combined cylinders.
|
| 8. | The higher expansion ratio extracts more work from the high-pressure gas created by the combustion process.
|
| 9. | It will reduce thrust to to keep the same length but increase expansion ratio to 500 : 1.
|
| 10. | Expansion ratios comparable to diesel engines can be achieved, while still using gasoline ( petrol ) fuel.
