Size distributions of diesel particles using water-containing fuels were studied.
Biodiesel containing 3% WA reduces PM, carbon, and PAHs in 0.010–18 渭m size ranges.
These reductions of emissions of submicron particles exceeded 85%.
Biodiesel blended with recycled waste solvents may be used as an alternative fuel.
Water plays a significant role on reducing biodiesel engine pollutant emission.
