Abstract
Emissions from diesel engines(rail, marine, construction equipment and other non-roadmobile sources) presently account for a significant part of themajor pollutants (SOx, NOx, VOC, PM, CO, and noise) thatare responsible for smog and for human health impacts.
The objective of this work is to identify effective ways to reduce emissions from direct injection Fiat diesel engine.The approach used here is the combustion of water-diesel emulsion in diesel engine, at different water ratios, at constant engine speed and variable engine load. The second set of tests was at constant load and variable engine speed. The results show improvement in NOx, UBHC, CO and CO2 reductions with increasing water emulsion percentage to 20%, accompanied with brake specific fuel consumption (BSFC) reduction also.

Keywords: water-diesel emulsion, performance, emissions, PM, noise.
