Abstract: Environmental pollution is a major problem in all countries around the world. Internal combustion engine (ICE) is considered one of the main sources of emissions, thus most countries are interested in using biodiesel as alternative fuel. Scientists, researchers, and manufacturers are facing the challenge of reducing fuel burning emissions and at the same time achieving the main technological requirements such as increasing vehicle performance, decreasing fuel consumption, etc. Some of recent studies indicate that many vehicles and movable equipments accepted to use of biodiesel blends (Bb). Mainly, the new engines can be operated with Bb of 20%, 30% and B100 (Pure Biodiesel). Nitrogen Oxides (NO_x) represents one of the exhaust gases that have a great impact on environmental conditions. This work presents an analytical study of NO_x emissions summarising the practical solutions to reduce NO_x emitted from diesel engine burning Biodiesel blends (Bb).

Keywords: biodiesel fuels; biodiesel blends; NO_x emissions; DE; diesel engine; ICE; internal combustion engine.
