Improvement of liquid fuel atomization for an internal engine using an auxiliary device
Controlled atomization is essential for reducing soot emission in practical diesel engines. In this work, an auxiliary device called a FAD (fuel activation device) was inserted into the fuel injection line to induce cavitation in the diesel spray. The performance of the FAD was examined in terms of pollutant emissions in a field test as well as aerosol sizes in lab-scale experiments. Experimental results showed that FAD reduced the size distribution of injected droplets and decreased the fuel consumption rate and emission amounts of PM10, CO, and NOx by 42%, 50% and 13.4%, respectively.
