evaluate the effect of hydroxyl gas HHO addition, as an engine performance improver, into
gasoline fuel on engine performance and emissions. HHO cell was designed, fabricated and
optimized for maximum HHO gas productivity per input power. The optimized parameters
were the number of neutral plates, distance between them and type and quantity of two
catalysts of Potassium Hydroxide (KOH) and sodium hydroxide (NaOH). The performance of …
