Abstract
Fossil fuels are widely used all over the world to power the motor vehicles. Due to superfluous consumption of these fuels, their reservoirs are depleting continuously. The huge demand of crude oil has caused the unprecedented price rise, environmental pollution, and global warming which directly affects the living beings as well as the surroundings in which they are surviving. Alternative fuels can suffice the demand with less adverse effects on the environment through the means of different sustainable technologies. Hydroxy gas (HHO) can be effective source of energy to combat these prominent issues. This work covers the experimental analysis of different parameters related to advantages and disadvantages of using HHO as a blend with gasoline and CNG fuel mixture. The analysis is based on engine performance and emissions. The experiments were performed on engine model fueled with a mixture of fuel and HHO gas. HHO was used as a fuel supplement. A compact HHO gas kit was installed in the engine compartment. A 219cc, four stroke, single cylinder spark ignition engine was used. No modifications were required in the engine design as HHO was used as a fuel supplement. The production of HHO was accomplished by the electrolysis of double distilled water in the presence of KOH(aq.) as an electrolyte. Products of water electrolysis consisted of H2 and O2 in the ratio of 2:1 by volumetric basis. Performance enhancement in overall engine characteristics such as brake power, specific fuel consumption, and overall efficiency was observed. Furthermore, a significant reduction in the emissions of unburnt hydrocarbons, carbon monoxide, and carbon dioxide was noticed. However, due to lean air-fuel mixture and tremendous peak combustion temperature the amount of NOx was increased.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
