Abstract
The target of this work was to study the effect of adding HHO to gasoline fuel on engine performance and emissions. HHO gas production per input power was achieved by designing, manufacturing, and optimizing the HHO cell. The optimized parameters were the amount of HOH added to the Gasoline as the experimental Study is done by measuring thermal efficiency and exhaust emission effect in many cases. First case Neat Gasoline and the remaining cases after adding HOH in different percentages of 5, 10, and 15 L/ min and then repeating the experimental tests with three different commercial Octane Boosters. The used engine is a Honda commercial OHV engine, air-cooled, four-stroke, and single-cylinder. Additionally, the Gas board exhaust gas analyzer was used to monitor the emissions of NOx, HC, and CO. The results indicated that the impacts of HHO and gasoline fuels on engine performance metrics like braking power, brake-specific fuel consumption, brake thermal efficiency, and exhaust emissions such as CO, NOx, CO2, and exhaust gas temperature were evaluated at different engine loads (lighting) (EGT). Except for CO and HC emissions in comparison to neat petrol operations, the results revealed that adding HHO gasoline combination with additives is the most successful in boosting engine performance and offering a more ecologically acceptable attitude toward exhaust emissions.
