| Title | Effects of High Concentration Nano Fuel on Different Density Emulsified Biodiesel | ||
| Keyword | |||
| Abstract | At present, scientists in various countries are looking for alternative fuels that can extend the service life of oil. Therefore, there is a market for demand, so research on low-pollution bio-diesel and water-emulsified fuel is gradually being discussed. From past research reports, we can know that the use of burning biodiesel will increase the emission NOx concentration. In order to solve the problem of biodiesel, we have changed the use of water emulsion fuel to effectively reduce the emission of NOx. However, the latent heat of vaporization in the water-emulsified fuel is high, which leads to an increase in the BSFC value and an increase in the HC emission concentration. Therefore, the addition of the nano-Al2O3 powder in the fuel improves the disadvantages of the water-emulsified fuel and the combustion characteristics of the fuel, thereby improving the fuel performance. Therefore, this study used 150ppm high-concentration nano-Al2O3 powder as an additive, added to three different density emulsion fuels with water content of 5%, 8% and 10%. The experimental results show that the water content is 10% high density. The high concentration of emulsion fuel, although it consumes more fuel, can improve engine performance and reduce emissions of smoke and NOx, and increase the concentration of HC emissions to increase the EGT value. |
