Effect of SI Engine Performance by Adding the Additive of Oxy Hydrogen

Abstract: The objective of this thesis is to improve engines performance and reduce the fuel consumption by mixing fuel with HHO gas. A gaseous fuel containing high percentages of hydrogen and oxygen is obtained directly from water by a special kind of electrolysis technology. This gaseous fuel is mixed with gasoline in the engine intake. This research presents the results obtained from the experiments concerning performance of petrol engine when it is operated at different loads. These tests emphasized the possibility of reducing fuel consumptions offered by the gaseous fuel in comparison with the engine operated on gasoline fuel alone. Experiments confirmed an improvement in engine performance, a reduction in fuel consumption.
