چکیده:

The purpose of this study is to compare the effect of Nitromethane (NM) and Nitroethane (NE) as nitrogenated additives and 2- methoxy ethyl ether (MXEE) as an oxygenated additive on physical property of fuel, combustion performance and emission from diesel engine. Meanwhile these nitrogenated additives have high oxygen content therefore are considered as oxygenated additives also. These additives blended with diesel fuel, 10% in volume. The experimental study was carried out on ECE R-96 8-modes cycle. The result showed that the use of these reduces viscosity but increases cetane index. The maximum cetane index resulted with MXEE additive. Nitrogenated additives increased brake thermal efficiency (BTE) and exhaust emission such as BSSOOT reduced to the minimum value 44% with NE. With MXEE the BSHC and BSNOx values increase slightly, these values with NM and NE increased significantly. In general low Soot and CO2 emission were measured with these additives.
