“…It has been used as a fuel additive in various researches using both petrol and diesel engines. Researchers have found that using HHO gas as an additive in regular internal combustion engines has resulted in a 10% increase in thermal efficiency, up to 34% decrease in fuel consumption and a reduced concentration of nitrogen oxides (NO x ), carbon monoxide (CO) and hydrocarbon (HC) emissions in petrol engines (El-Kassaby et al, 2016) and 41% reduction of particle emissions, 13.5% reduction of CO emissions and 5% reduction of HC emissions in diesel engines (Bari et al, 2022;Yilmaz et al, 2010).…”

“…Although several researchers have studied about hydrogen on-board through water electrolysis (Bari et al, 2022;Martin et al, 2019;Rodríguez Matienzo, 2018), however, the analyzer measurements in the instantaneous emissions under standard New European Driving Cycle (NEDC) is still sparse and a very few studies discusses the use of hydrogen as an additive fuel during cold start or idle operation. The energy saving and pollutant emission reduction of…”

Pollution reduction related to combustion engines is considered to be an important issue around the world. Hydrogen as an additive energy has been utilized for alternative fuel since it need not require any modification. Particularly, it has been considered as a sustainable option for diminishing petroleum dependence and air pollutant emissions. In this study, we investigated the tailpipe emission with hydrogen addition for different driving behavior such as cold-start, idle, urban (UDC) and extra-urban (EUDC) under New European Driving Cycle (NEDC). The results showed that urban driving could attribute the most emissions in comparison to the high speed mode. Hydrogen addition enhanced the combustion process and the average reduction rates were observed 21.6% & 65.8% for hydrocarbon (HC), 2.37% & 85.4% for carbon monoxide (CO), and 7.53% & 59.3% for nitrogen oxides (NOx) when run at UDC and EUDC, respectively. The wide flammability of hydrogen ensures a homogeneous fuel-air mixture for complete combustion and reduces the HC, CO and NOx emissions. It is noteworthy that starting with less amount of hydrogen could greatly decrease HC followed by CO and NOx. Compared to conventional gasoline (G0), the average fuel consumption was reduced by 1.3% when a small amount of hydrogen was applied as an additive fuel.

“…To obtain higher yields, it is necessary to increase the size of the generating device, raising the cost. In order to make hydrogen production more accessible, it is necessary to make the process compatible with smaller energy sources, such as residential PV systems or car alternators as well as making the equipment cheaper [1][2][3][4].…”

Pulsed electrolysis has become a promising research topic in recent decades due to advances in solid-state semiconductor devices. These technologies have enabled the design and construction of simpler, more efficient, and less costly high-voltage and high-frequency power converters. In this paper, we study high-voltage pulsed electrolysis considering variations in both power converter parameters and cell configuration. Experimental results are obtained for frequency variations ranging from 10 Hz to 1 MHz, voltage changes from 2 V to 500 V, and electrode separations from 0.1 to 2 mm. The results demonstrate that pulsed plasmolysis is a promising method for decomposing water for hydrogen production.
