| 1. | One ISC approach is called THAI for Toe to Heel Air Injection.
|
| 2. | The original air injection point became known as the upstream injection point.
|
| 3. | In reverse the air injection and the ignition occur from opposite directions.
|
| 4. | However, by not using compressed air injection it is less efficient.
|
| 5. | The main improvement is the modernized fuel and air injection system.
|
| 6. | The " Air Injection Reactor " secondary air injection system was still present.
|
| 7. | As well, the US-only models got an air injection system for emissions reduction.
|
| 8. | The main improvement was the modernized fuel and air injection system.
|
| 9. | The " Air Injection Reactor " secondary air injection system was still present.
|
| 10. | In 1975, air injection was added to the Japan-market "'18R-GR "'for improved emissions.
