Abstract

Internal combustion engine (ICE) is an old technology and has a long history of evolution. The need for another power source in order to maintain its sustainability for the future is being much highlighted in today’s scientific community. Amongst the different alternative fuels, HHO gas is found to be the most viable solution in regards of its generation and storage as it is considered renewable, recyclable, and non-polluting fuel. The use of HHO gas in gasoline engines is relatively new. Any improper addition or modification to the engine may cause performance deterioration instead of enhancement. In this study, various HHO plates with different surface roughness are fabricated for HHO gas production analysis to match the specified engine. Further test will be done by tuning the input voltage supply and weight of catalyst used. The optimum flowrate of HHO gas will then be commissioned into the air intake manifold of the engine for the analysis of performance and emission. The various surface roughness of the plates are obtained by grinding and polishing the surface to mirror-like surface and categorised to non-polished, one-sided polished, and fully polished. The surface roughness of the plates are inspected with metallographic microscope and measured with a roughness tester. The analysis of HHO gas production with the three types of plates are done with a flow meter while the specified engine is set up with a dynamometer for analysis of performance and emission. The manipulated variables are the voltage input and weight of catalyst used to find the optimum setting for the specified engine. By commissioning the HHO gas into the air intake manifold, the analysis of performance and emission are done to evaluate its effectiveness. In the findings, the rougher surface of the plates produced the most HHO gas under the same condition. The performance of the engine only improved by a small margin but the emission improved vastly with the addition of HHO gas
