- •
Using double injection strategy, turbulent kinetic energy can be improved with slight decrease in mixture homogeneity.
- •
Retarded first injection timing reduces vapor fuel loss to intake port.
- •
Double injection increases tumble intensity.
- •
High turbulent intensity caused by double injection increases flame propagation speed.
