Table 6
Summary of the different fuel blends effects on the spray characteristics compared to pure HFO fuel.
| | Spray parameter | Different blended fuel @ = 600 bar | Different blended fuel @ = 1000 bar | | B10 | B15 | B20 | B10 | B15 | B20 |
| | Spray length | 0.78% | 0.11% | 0.15% | 0.56% | 0.35% | 0.14% | | Particles volume in parcels | 3.40% | 3.65% | 2.96% | 11.97% | 6.33% | 21.32% | | Number of particles | 59.70% | 39.76% | 39.18% | 61.88% | 50.17% | 67.46% | | Average of particles diameter in parcels | 9.81% | 4.63% | 21.29% | 6.47% | 37.37% | 42.66% | | Average velocity | 17.81% | 13.41% | 18.04% | 15.33% | 8.02% | 2.75% |
