Peer-reviewed literature reports that supplying water electrolysis products, such as HHO gas generated onboard, to internal combustion engines can improve engine performance and reduce fuel consumption.
Restrictions imposed by regulatory frameworks, the high cost of fuels, environmental impacts and the efficiency of internal combustion engines encourage research into reducing the consumption of fossil fuels. Additionally, to think about the alternative energy sources. In compression ignition engines, researchers around the world have been working for years on the use of biodiesel fuel, in order to reduce emissions and the consumption of diesel fuel. In other investigations, water electrolysis products obtained in an HHO gas generator and supplied to an internal combustion engine allow for improving performance, reducing fuel consumption and emissions. HHO gas is a mixture of hydrogen and oxygen resulting from the electrolysis process of water, with energy supplied by an electric source or accumulator. The main objective of this work is to evaluate the influence of an HHO generator products in a diesel engine that operates with diesel fuel produced in Colombia with 10 % biodiesel. The objective of this study is evaluated the influence of gas HHO on mechanical performance, fuel consumption, and polluting emissions in a single-cylinder diesel engine, performing a comparative analysis when the HHO generator operates with different amperages. The results showed a 25 % average reduction in fuel consumption between 1500 y 2500 engine revolutions when the HHO cell operated with 8 amperes. The breaking power maximum value increased a 10 %, and CO and PM10 emissions were reduced by 14 % and 53 %, respectively, at 1000 rpm. It is possible to conclude that supplying water electrolysis products in the fuel-air mixture increases the mechanical performance of a diesel engine and reduces polluting gas emissions. Additionally, research areas are opened in the development of HHO generators and standards for the application of this technology
This abstract encapsulates the essence of the research paper focusing on the design, development, and testing of an HHO (Hydrogen-Hydrogen-Oxygen) generator. The study aims to investigate the feasibility and efficacy of HHO technology in producing hydrogen gas for various applications, including engine decarbonization, renewable energy production, and industrial processes. The research begins with an in-depth exploration of HHO generation principles, electrolysis techniques, and system components. Through systematic design and engineering processes, a prototype HHO generator is developed, integrating innovative features to enhance efficiency, safety, and reliability. Experimental testing is conducted to evaluate the performance of the HHO generator across a range of operating conditions. In this study, we explore the utilization of oxy-hydrogen gas (HHO) as an supplementary source for internal combustion engines. The electrolysis process of water with an electrolyte (such as KaOH) produces HHO gas, which can address fossil fuel shortages and mitigate environmental pollution.
Hydrogen gas is one of the alternative fuels that is currently being widely researched. HHO generator is a tool with the working principle of water electrolysis and is used to produce hydrogen gas. In some studies, peat water has been considered to be used as an electrolyte. This research uses experimental methods to obtain hydrogen gas results from peat water electrolysis. The electrolysis reactor used can handle as much as 400 ml of peat water. The electrodes are stainless steel (SS) with a large cross-sectional area of 0.01884 m2. The electric power used was 12 Volts DC and the time in the electrolysis process was 1 minute. Based on the results of the research that has been done, among others, where the increase in HC in the exhaust gas in Aquades water looks very efficient at the initial rotation at 2000 rpm which produces a thermal efficiency of 60% While in peat water the increase in HC in the exhaust gas in Aquades water looks very efficient at the initial rotation at 2000 rpm which produces a thermal efficiency of 90%. The influence of rpm and the unstable rotation of rpm causes the CO value in the exhaust gas of the vehicle to be unstable where at low rotation readings 223. 24 ppm, middle 634.94 ppm and top 606.89 ppm, it can be seen that in the upper round the value even decreases from the middle round, while in HHO peat water when the low round reading is 104.4 ppm, middle 101.94 ppm and top 121.29 ppm, it can be seen that in the upper round the value increases from the initial round to the top.
