Modeling and analysis of diesel engine with addition of hydrogen-hydrogen-oxygen gas

Abstract

The brown gas or hydrogen-hydrogen-oxygen gas is considered as a hydrogen fuel with oxygen present in it. The effect of hydrogen-hydrogen-oxygen gas induc-tion in a direct injection diesel engine using GT-POWER software is discussed in relation with the rate of pressure rise and heat release rate. The engine is mod-eled in GT-POWER environment. The single zone combustion model has been adapted with Woshini heat transfer model. In this model the effect of induction of hydrogen-hydrogen-oxygen gas has been incorporated and analyzed for 1, 3, and 5% of hydrogen-hydrogen-oxygen gas in volume basis. The injection rate is mod-ified for accommodating the hydrogen-hydrogen-oxygen gas in the model. The results have given the promise of higher rate of heat release with shorter combus-tion duration. Higher levels of hydrogen-hydrogen-oxygen gas have shown the advanced start of combustion as well as reduce the combustion duration.
