Experimental study of the use of brown gas HHO (Hydro Hydrogen Oxy) produced by variation of the number of electrodes plates on the performance of a 4-step motor

The purpose of this study was to determine the production of HHO gas produced by the wet sheel type HHO generator which can be used as a premium mixture for alternative fuels on a 4-stroke motorbike. The electrodes used are 304 Stainless Steel plates with a size of 100 × 50 mm with a plate thickness of 1 mm. The distance between the electrode plates used is 3 mm and the electrolyte of sodium bicarbonate (NaHCO3) is 40 grams / 2 liters of pure water. Variations in the number of 6 electrode plates, 12 pieces and 18 pieces arranged vertically with a 12V 60 Ah power supply, while the motor used is a 4-stroke motor with a variation of flowrate brown gas 0 ml/s, 1 ml/s, 2 ml/s, 3 ml/s. The results showed that the best performance was obtained at the HHO generator with 18 electrode plates at an average production rate of 0.59 liters/minute and an efficiency of 61.50%. The highest power and torque were produced by the addition of Brown Gas at a flow rate of 3 ml/s of 8.59 HP (an increase in power by 10.84%) and 9.5 Nm (an increase in torque of 8.96%) when compared to a flowrate of 0 ml/s. In addition, with the addition of Brown gas at a flow rate of 3 ml/s, the use of specific fuel (SFC) became more efficient by 7.99 x 10-3 kg/kwh or a decrease of 19.37% compared to the 0 ml/s flowrate.
