In the present research, the different simultaneous reductions of oxides of nitrogen (NOx) as well as smoke are compared. The methods are gasoline fumigation (GF), exhaust gas after treatment using water scrubbing (EGAT) method and gasoline fumigation along with nanoadditive. Gasoline fumigation was achieved by controlling the electronic injector fitted at the intake manifold using the open ECU software. An exhaust management set-up is invented, which is attached to the tailpipe of the engine. This precedes the exhaust and injects water in the tailpipe and sends it over the silica gel chamber. The aluminium oxide nanoliquid was blended with diesel in mass fractions of 50 ppm. The features of a single direct injection (DI) diesel engine are studied for GF, EGAT and gasoline fumigation along with 50 ppm nanodiesel blend (50AONP – D +GF). EGAT shows higher NOx and smoke emission reductions compared than diesel, gasoline fumigation and gasoline fumigation with nanoadditives. The simultaneous reduction in NOx and smoke, increase in BTE at high power and reduction in CO and HC when nanoadditive is used, shows gasoline fumigation as the effective method for diesel engines. |
