Effect of Injection Pressure
High-Speed Schlieren Movies of Diesel Sprays
| Parameter | Low Pressure Injection | High Pressure Injection |
|---|---|---|
| Ambient O2 [%] | 21 | 21 |
| Ambient Temperature [K] | 1000 | 1000 |
| Ambient Density [kg/m3] | 28 | 28 |
| ΔPinj [MPa] | 71 | 136 |
| Orifice Diameter [mm] | 0.200 | 0.200 |
Fuel is #2 diesel fuel. Injector tip to wall is 109 mm.
The spray penetration rate increases with increasing injection pressure.
