- •
The negative effect of the pilot injection is that it restricts the advancement of the split injection.
- •
A pilot injection with the correct parameters can effectively improve mixing and combustion characteristics.
- •
The mechanisms of the pilot-main injection interaction are illustrated for split injections.
- •
The split injection is optimized for both the negative and positive effects of the pilot injection.
