Experimental investigation on performance emission and combustion characteristics of a di diesel engine operating with oxygen enriched hydrogen gas

Abstract

The objective of this research was to investigate the performance emission and combustion characteristics of oxygen enriched hydrogen gas as a fuel for direct injection diesel engines The research signified that oxygen enriched hydrogen is a suitable fuel for direct injection diesel engines In this research oxygen enriched hydrogen gas was used as a dual fuel along with petroleum diesel in the engine operation In the present research, hydrogen was produced along with oxygen by electrochemical reaction of water This gas mixture was coined as oxygen enriched hydrogen OEH gas This gas mixture was aspirated along with intake air of the test engine newlineThe test engine used for this research was Kirloskar make single cylinder water cooled four stroke vertical cylinder naturally aspirated stationary direct injection diesel engine developing a rated power of 5 9 kW at a rated speed of 1800 rpm and having a compression ratio of 17 5 1 Standard instruments were used to measure the performance and engine out emissions such as carbon monoxide CO carbon dioxide CO2 unburned hydrocarbon UBHC oxides of nitrogen newline newline
