“…HHO gas dry cell generator experimental productivity can be calculated from the following Equation 38 :

HHO productivity = \frac{volume of gas collected in graduated cylinder}{time},

HHO cell efficiency = \frac{Energy gained}{Energy consumed},

Energy consumed = volt \times ampere \times time,

Energy gained = m_{HHO} \times {LHV}_{HHO} .

This study is modification of the conventional single-slope solar still to improve in the day-to-day production of potable water. The studied solar still is modified to active solar still using new technique which uses oxy-hydrogen (HHO) gas burning as a fuel to increase the temperature of the saline water in the solar still. The power sustainability of HHO gas that used in sea water desalination is one of the main research goals. HHO dry cell is implemented to generate the required amount of HHO gas which is used as fuel of gas furnace. The traditional gas furnace uses HHO gas as fuel without modifications. Two identical HHO gas generators and a gas furnace are integrated with a solar still and four solar panels have power 1000 W, each photovolatic solar module has dimensions 1650 mm × 992 mm × 46 mm. The suggested solar still is fabricated and verified for selected months (June, July, and August) with the meteorological conditions of Ismailia, Egypt. The ratio between the solar still

“…Hydrogen due to its low viscosity, wide ignitability range and high flame and dispersion rates, emerged as a sensible choice [15,[24][25][26]. It was found that the CO emissions decreased as a function of hydrogen percentage addition and the air-fuel proportion [27]. Moreover, the total hydro-carbons (THC), dropped with greater hydrogen percentages.…”

The rising global warming concerns and explosive degradation of the environment requires the mainstream utilization of alternative fuels, such as hydroxy gas (HHO) which presents itself as a viable substitute for extracting the benefits of hydrogen. Therefore, an experimental study of the performance and emission characteristics of alternative fuels in contrast to conventional gasoline was undertaken. For experimentation, a spark ignition engine was run on a multitude of fuels comprising of gasoline, Liquefied petroleum gas (LPG) and hybrid blend of HHO with LPG. The engine was operated at 60% open throttle with engine speed ranging from 1600 rpm to 3400 rpm. Simultaneously, the corresponding performance parameters including brake specific fuel consumption, brake power and brake thermal efficiency were investigated. Emission levels of CO, CO2, HC and NOx were quantified in the specified speed range. To check the suitability of the acquired experimental data, it was subjected to a Weibull distribution fit. Enhanced performance efficiency and reduced emissions were observed with the combustion of the hybrid mixture of LPG with HHO in comparison to LPG: on average, brake power increased by 7% while the brake specific fuel consumption reduced by 15%. On the other hand, emissions relative to LPG decreased by 21%, 9% and 21.8% in cases of CO, CO2, and unburned hydrocarbons respectively. Incorporating alternative fuels would not only imply reduced dependency on conventional fuels but would also contribute to their sustainability for future generations. Simultaneously, the decrease in harmful environmental pollutants would help to mitigate and combat the threats of climate change.

one of the most effective solutions for improving the performance and reducing the emission of spark ignition engine is introducing a hybrid fuel with gasoline. Hydroxy gas (HHO) that is generated from water electrolyzes process has a significant effect in enhancing the thermal efficiency and reducing fuel consumption rate and the resulted combustion emissions of SI engine. Because HHO gas has significant advantages rather than fossil fuels. In this study a fuel dry cell is constructed and tested in different concentrations of electrolysis water solutions and with alternating the number of neutral plates, to obtain the most economic, safe and suitable cell for the desired engine operation conditions . The engine used is a 183 CC single cylinder air cooled (Robin EY 20-3) without any change in engine construction. The load used for this purpose is a centrifugal water pump with a maximum delivery flow rate of 520 L/min. First, the engine is allowed to run separately without the cell under different speeds of 1200, 1500,2000,2500,3000 and 3500 rpm, then the cell is connected to the engine. Many different operating parameters are measured such as pump flow rate, fuel consumption rate, water pressure, exhaust temperature, and engine emissions; HC and CO. The experimental results show that increasing the concentration of electrolysis solution or reducing the number of neutral plate increased the production rate of the gas, but it has undesirable effect on increasing the temperature of the cell. And for engine performance the average enhancement of engine efficiency, reductions in break specific fuel consumption, reduction in CO and HC emissions are 5.44%, 16.9%, 4.8%, and 5.5%, respectively
