Experimental Investigation on Engine Performance and Emission Parameters by Using Different Additives in Diesel Engine

The present work is mainly concerned with an experimental investigation to study the diesel engine performance, combustion, noise and emission characteristics using different combination of blends with diesel to solve both the energy and environmental concerns. All relevant information was analyzed to construct a precise summary of background information which included the history of different additives, advantages and limitations, physical and chemicalproperties of additives and their emissions. The emissions from the tailpipe of the engine such as nitrogen oxide (NOx), unburnt hydrocarbon (HC), carbon dioxide (CO2) and carbon monoxide (CO) were recorded and explained. The experiments were conducted using different loads to collect the emission data. The outcome of this study reveals that no single blend can satisfy all of the requirements. Achievement of one aspect can only be achieved at the expense of other. As far as emissions are concerned two major contributors of NOx and HC are found to be inversely proportional. To reduce one aspect, a compromise of other is required. Results were classified into two major categories i.e., the trends shown by oxygenated and non-oxygenated blended fuel
