Abstract

Hydrogen Hydrogen-Oxygen (HHO) gas is a renewable energy source that is gaining attention as a potential substitute for fossil fuels. HHO can be derived from water (H₂O) through a process called electrolysis using a dry cell HHO generator. This study aims to investigate the impact of adding HHO gas to Pertamax fuel with current variations of 2A, 3A, and 4A on exhaust emissions. The testing involves a four-stroke motor vehicle and a wet cell generator powered by the motor's battery. Emissions measured include CO, CO₂, HC, and O₂ using a gas analyzer. The testing is conducted at engine speeds of 2000 rpm, 2500 rpm, 3000 rpm, 3500 rpm, and 4000 rpm, both with and without HHO addition. Results indicate that the addition of HHO to Pertamax significantly reduces CO levels, with a 63% decrease recorded at 4A. HC levels also show a 21% reduction when using the same HHO mixture. Furthermore, the introduction of HHO raises O₂ levels, although a decrease of 6% in O₂ concentration was noted in the 4A mixture. Conversely, the CO₂ concentration increased by 53% when using Pertamax mixed with HHO at 4A. In conclusion, the study finds that the combination of Pertamax fuel and HHO at a current of 4A is more effective in reducing emissions in four-stroke engines compared to using Pertamax alone. This suggests a viable approach for enhancing fuel efficiency and environmental performance in motor vehicles.
