Motorcycle Engine Fueled with Gasoline Enriched by HHO Produced with Regenerative Braking Energy

The solution of adding hydrogen and oxygen gas (called HHO gas, hydroxyl gas) to traditional fuel has been interested by scientists in recent years to improve the combustion process of internal combustion engines. This article presents the content of designing and manufacturing HHO gas generation system by water electrolysis method with electrolytic energy source from available generator of Honda Lead 100cc motorcycle and energy from regenerative braking system. This regenerative braking system located at the front wheel of the motorcycle helps to brake the motorcycle and recovers electrical energy during braking. When the motorcycle is operating normally, the generator is idling, so the motorcycle still operates smoothly. When the brake is pressed, the generator will generate a magnetic field to brake the motorcycle and generate electricity, which is stored in the battery and then supplied to the HHO generator. The power test results obtained from regenerative braking when braking at a speed of 50 km/h are 543.46 W, the ability to generate HHO gas reaches a flow of 0.6 l/min. Test results of the motorcycle on the Super Dyno 50L test bench, the power of the motorcycle increased by 14%, the fuel consumption of the test motorcycle on the road decreased by 13.2%.
