Adelfa (NOME - Nerium Oil Methyl Ester) with DEE as the fuel additive for NOx reduction in DI Diesel engines – An experimental investigation

Abstract

Biodiesel would be a futuristic alternative for compression ignition engines because of its environmental benefits and the source being renewable. Jatropha, Pongamia pinnata, Mahua, cotton seed are the oils being tested by the researchers. In this experimental investigation Adelfa biodiesel (Nerium Oil Methyl Ester – NOME) has been used as the test fuel. The most common method of production of biodiesel is by transesterification. In most of the researches, suggested biodiesel blend was 20% by volume with petroleum diesel. Though biodiesel fuel show an appreciable results on performance and few emission parameters, the penalty being the elevated oxides of nitrogen (NO_x) emission. This problem persists in almost all the biodiesel blends. In this experimental research, Di ethyl ether (DEE) has been used as a fuel additive (20% Adelfa by volume with diesel + DEE) focusing on reducing emission and improving efficiency. Comparison between diesel, A20 and A20 + DEE with various proportions has been analyzed. Measured quantities were within the range of prescribed emission standards.
