EXPERIMENTAL INVESTIGATION ON DRY CELL HHO GENERATOR WITH CATALYST VARIATION FOR REDUCING THE EMISSIONS

Abstract

Air pollution is now largely attributable to the use of vehicles that produce high pollution. The purpose of this study is to determine the contribution of HHO generator in reducing air pollution by looking at the emission level of exhaust gas. In addition, to know the type of catalyst is the best in lowering the level of these pollutants. The research using an experimental method. The subject is Honda Supra X 125 the Year 2013 by adding a dry cell HHO generator. Emissions data collection using gas analyzer against the use of HHO generator with catalyst variation (KOH, NaOH, and NAHCO3). Data analysis was done by descriptive quantitative. The results showed (1) All types of catalysts studied (KOH, NaOH, and NAHCO3) as electrolyte solution media for HHO generators which greatly affected the reduction of CO and HC emissions in vehicles, (2) Catalyst NaOH type is the most effective catalyst in reducing CO and HC emissions. This is evidenced by the results of NaOH solution to obtain average CO gas concentration is 0.13% or a decrease of 81.74% and the use of NaOH solution to get an average concentration of HC gas is 524.33 ppm or a decrease of 69.62% when compared to standard conditions (without HHO generator).
