| Summary: | Exhaust gas re-circulation is a method used in compression ignition engines
to control and reduce NOx emission. These emissions are controlled by
reducing the oxygen concentration inside the cylinder and thereby reducing
the flame temperature of the charge mixture inside the combustion chamber. In
the present investigation, experiments were performed to study the effect of
exhaust gas re-circulation on performance and emission characteristics in a
four stroke single cylinder, water cooled and constant speed diesel engine.
The experiments were performed to study the performance and emissions for
different exhaust gas re-circulation ratios of the engine. Performance
parameters such as brake thermal efficiency, indicated thermal efficiency,
specific fuel consumption, total fuel consumption and emission parameters
such as oxides of nitrogen, unburned hydrocarbons, carbon monoxide, carbon
dioxide and smoke opacity were measured. Reductions in NOx and CO2 were
observed but other emissions like HC, CO, and smoke opacity were found to
have increased with the usage of exhaust gas re-circulation. The 15% exhaust
gas re-circulation was found optimum for the engine in the aspects of
performance and emission. |
