Abstract
This paper analyzes effect of biodiesel on engine power, fuel consumption, emissions: nitrogen oxides (NOx) and particulate matter (PM) while the effective power is maintain constant. Biodiesel is a renewable, alternative diesel fuel of domestic origin derived from a variety of fats and oils by a transesterification reaction.
Considering global energy policies, more and more governments try to increase the usability of biodiesel for powering motor vehicles. Cars manufacturing companies and private users are reluctant in using biodiesel, especially in current engines. Because of this, it is difficult to achieve the targets of increases the usage of biodiesel in ICE. There is a lack of knowledge on emissions of an engine what is fueled with biodiesel.
An advantage of biodiesel is its potential to significantly reduce most regulated exhaust emissions, including particulate matter (PM), with the exception of nitrogen oxides (NOx).
