Analysis of selected toxic components in the exhaust gases of a CI engine supplied with water-fuel emulsion

This study looks at the impact on selected toxic exhaust gas components in a compression ignition engine supplied with diesel-fuel emulsion. During the empirical research, a turbocharged PERKINS 1104C-E44T diesel engine was supplied with water-fuel emulsion where water content in the mixture was 15% by volume and diesel fuel. The tests were performed with load characteristics at two speeds of the engine crankshaft at maximum torque speed of 1,400 rev/min and maximum engine power speed of 2,200 rev/min. At each operating point of the engine concentrations of toxic exhaust gases we recorded carbon monoxide CO, hydrocarbons HC, nitrogen oxides NOx, and particulate matter PM. On the basis of results and calculations, specific emissions of toxic substances in accordance with ISO 8178 were designated.
