“…Esto permitiría determinar el volumen de gas administrado que reemplaza parte del combustible tradicional, disminuyendo el consumo de gasolina. Un dispositivo de dosificación del HHO llamado HECU (unidad de control electrónico de hidroxi) se utilizó en [21], el cual cumplió la función de regular la salida del gas HHO mediante el control del voltaje y la corriente que llega a la celda, para obtener eficiencias mayores en la combustión de motores de encendido por compresión. …”

“…Los autores mostraron que los porcentajes de emisión de contaminantes se reducían hasta en un 50% de óxidos de nitrógeno, 20% de monóxido de carbono y el gasto de combustible en un 30 % al ser agregado a la mezcla de combustión gas HHO. Yilmaz et al [21] mostraron aumentos de cerca del 19,1% del par motor, además de la reducción de CO en un 13,5%, emisiones de hidrocarburos en un 5% y, respecto al consumo específico de combustible, una reducción del 14%.…”

RESUMENLos motores de combustión interna a gasolina tienen conocidos problemas de eficiencia térmica y alto índice de emisión de gases contaminantes. Por otro lado, existen procesos químicos y eléctricos que han permitido obtener fuentes de energía limpia del agua. La electrólisis permite mediante un proceso electroquímico la obtención de gas de hidrógeno y oxígeno, de cuya mezcla se obtiene HHO. Las características moleculares del HHO permiten la disminución de gases tóxicos al ambiente y el ahorro de combustibles hidrocarbonados en motores de combustión interna. En este trabajo se investigan los beneficios potenciales de la mezcla de HHO como aditivo a los combustibles fósiles, en particular, la gasolina comercial. Se describe el diseño de un sistema con una celda electrolítica y se evalúa el desempeño de un motor de 110 cm 3 en términos del consumo específico de combustible, potencia, torque y emisión de gases.PALABRAS CLAVE: electrólisis; celdas de oxihidrógeno; motores de combustión interna; energía limpia; combustibles. ABSTRACTGasoline internal combustion engines have known issues related to thermal efficiency and high emission of polluting gases. On the other hand, there are chemical and electrical processes that have provided sources of clean energy from water. Electrolysis allows the production of hydrogen and oxygen gas by means of an electrochemical process, from which HHO is obtained. The molecular characteristics of HHO allow the reduction of toxic gases to the environment and the saving of hydrocarbon fuels in internal combustion engines. In this paper, we investigate the potential benefits of HHO mixtures as an additive to fossil fuels, in particular, commercial gasoline. We describe the design of a system with an electrolytic cell and evaluate the performance of a 110 cm 3 engine in terms of brake specific fuel consumption, brake power, brake torque and gas emissions.

“…HHO gas is referred as brown gas which is a weekly bonded water molecule in gaseous state 2:1 molar mixtures of hydrogen and oxygen [2]. HHO production occurs by electrolysis process by using different electrolytes such as KOH, NaOH, NaCl, in different electrode designs in a leak proof reactor [3]. In HHO generator, for production of oxy-hydrogen gas in which different electrode material such as S-302, S-306, S-309 and S-316 L are used with electrolytic solution for electrolysis of water and mixed with conventional fuel like petrol or diesel.…”

Internal combustion engine is used in daily life activity. Fossil fuels are primary fuels which are used in IC engines because of increasing consumption day by day its alarming that these will deplete in near future. Researchers in field of inter combustion trying to use alternate fuels to fulfill energy demand of IC engine. Among the others, hydrogen is capturing attention as alternate fuel in engine for proper combustion without smoke as there is no carbon is present in it. In this article, hydroxy (HHO) gas has many excellent combustion properties that can be used for improving performance characteristics of diesel-fired Compression Ignition (CI) engines. Brown gas (HHO) was produced by using the electrolysis process with KOH (aq) as catalyst with stainless steel electrodes in a leak proof plexiglass reactor was presented in ongoing piece of writing. Produced gas is used as supplementary fuel in inlet manifold of engine test bed (modal#TQ200) which has one cylinder, air cooled, four stroke compressed ignition. Performance characteristics of engine were recorded under the same test condition with and without installation of HHO generator. Experimental results were taken over the range of speed from 1950 to 3450 rpm using hydraulic dynamometer at constant load condition of torque 2 N-m. Different engine performance parameters were calculated like engine brake power, the brake specific fuel consumption, the thermal efficiency, the mechanical efficiency and the specific fuel consumption with or without HHO gas. The results clearly indicated that engine's brake power, thermal efficiency and mechanical efficiency increased 22%, 47% 24%, respectively while engine's brake specific fuel consumption and specific fuel consumption (SFC) decreased upto maximum value of 35% and 27% respectively compared with engine operating without HHO generator. Main objectives of this research are to decrease the fuel consumption and increase power and efficiencies of CI engine and successfully achieved as witnessed in results.

Original scientific paper The paper proposes to analyse experimentally the influence of using oxyhydrogen gas, resulting from a process of electrolysis produced on board the vehicle, in supercharged compression ignition engine. The experiment consists in the series of the constant load tests (the same position of the accelerator), on the chassis dynamometer, initially starting with conventional fuel (standard diesel oil) and in the second phase by introducing the oxyhydrogen through engine manifold of the vehicle, with different volume percentages. The experimental data reveal a positive influence of the added oxyhydrogen on opacity of the flue gas and an increase of the NOx concentration. The mechanical parameters of the engine just highlighted certain trends, resulting in definitely the favourable enriching influence of oxyhydrogen.Keywords: compression ignition engines; diesel; flue gas opacity; HHO; hydrogen; internal combustion engine; NOx; oxyhydrogen Niskotlačno ubrizgavanje elektrolitičkog plina u motore s turbokompresijskim paljenjemIzvorni znanstveni članak U radu se predlaže eksperimentalna analiza utjecaja primjene elektrolitičkog plina (oxyhydrogen gas) kao rezultata postupka elektrolize provedene na vozilu, u motoru s kompresijskim paljenjem. Eksperiment se sastoji od niza testova trajnog opterećenja (isti položaj akceleratora), na šasiji dinamometra, započinjući s uobičajenim gorivom (standardno gorivo za diesel motore), a u sljedećoj fazi uvodeći elektrolitički plin (plin kisika i vodika) kroz razdjelnik motora vozila, uz različite postotke volumena. Eksperimentalni podaci pokazuju pozitivan utjecaj dodanog elektrolitičkog plina na neprozirnost dimnog plina i porast NOx koncentracije. Mehanički parametri motora istaknuli su određene trendove, rezultirajući s definitivno korisnim obogaćujućim utjecajem elektrolitičkog plina.
