Efficient Use of Oxy-hydrogen Gas (HHO) in Vehicle Engines

Abstract

The electrolysis process of water with electrolyte (NaOH) produces oxy-hydrogen (HHO) gas that can be used as an energy source to solve the shortage problem of fossil fuel and reduces the environmental pollution. In this study, HHO dry cell generator was designed, fabricated and tested experimentally to investigate its performance. The hybrid internal combustion engines using HHO is considered one of the most important studied applications. The engine performance and gas emission are investigated for two different engines; 150CC old engine with carburetor and 1300CC new engine with Electronic Control Unit (ECU). The results recorded the consumption of the fuel is reduced by 14.8 % for 150CC engine and 16.3 % for 1300CC engine. HHO gas reduced the emission gases by 33 % and 24.5 % reduction in CO and 27.4 % and 21 % reduction in HC for 150CC and 1300CC engines respectively.
