“…The results indicate that higher brake thermal efficiency can be attributed to better mixing of H 2 /O 2 with air, which results in better combustion. Similar results for the brake thermal efficiency of the hydrogen blends have also been found in earlier studies (Saravanan et al, 2007(Saravanan et al, , 2008Bose and Maji, 2009) that used diesel as the main fuel and pure hydrogen as an additive injected into the air intake port during the intake stroke. Saravanan et al (2007) found that brake thermal efficiency increased from 23.6% to 29.4% when running a diesel engine at 1500 rpm with 10 L/min hydrogen for intake port injection timing of 5° after top dead centre (ATDC) with an injection duration of 90° crank angle (CA), compared to diesel.…”

Bose and Maji (2009) found that brake thermal efficiency for hydrogen with diesel as the ignition source was 34.1% at 80% load with a hydrogen flow rate of 0.15 kg/h, whereas that of baseline diesel fuel was 30.2%.…”

This study investigated emission reductions of polycyclic aromatic hydrocarbons (PAHs), hydrocarbons (HCs), carbon monoxide (CO), carbon dioxide (CO 2 ), particulate matters (PM), and nitrogen oxides (NO x ) from a heavy-duty diesel engine (HDDE) at one low load steady-state condition, 24.5% of the maximum load (40 km/h), using premium diesel fuel (PDF) mixed with various amounts of H 2 /O 2 . Measurements showed that the mixed fuel of HO60 reduced the brake specific fuel consumption (BSFC) most, by an amount of 12.6%, as compared with PDF. Meanwhile, with HO60, the emission of air pollutant was deceased by 32.3% for PAHs, 9.5% for HCs, 7.2% for CO, 4.4% for CO 2 , and 19.3% for PM, but the emission of NO x was increased by 9.9%.

“…The HC emissions of WPO-MEK are lower compared to diesel and it is further lowered for hydrogen inducted at 2 lpm and 4 lpm [22]. Since hydrogen has no carbon, burning of hydrogen along with WPO-MEK emulsion leads to reduced hydrocarbon level.…”

Esters of vegetable oil and bio oil produced by pyrolysis of various biomass resources have greater scope as alternative fuels for the future in power and transportation sectors. In this experiments were conducted to evaluate the combustion parameters of a compression ignition engine fuelled with biodiesel-bio oil emulsion and hydrogen on a dual fuel mode. Hydrogen was inducted in small quantities in a diesel engine whereas an emulsion of bio-oil and methyl ester of karanja was injected into the cylinder as a main fuel. The impact of dual fuel mode on rate of pressure rise, peak pressure, ignition delay and heat release rate of the engine were studied. The results were compared with diesel fuel operation and presented in this paper.keywords -bio-diesel, biomass, bio-oil, emulsion, hydrogen enrichment, pyrolysis.

“…Se probó la inyección de varios caudales de hidrógeno en el colector optimizado de un motor diésel, mostrando que la mejor condición de operación de la inyección de hidrógeno era iniciarla en el punto muerto superior (PMS), manteniéndola por 30º y con un flujo de 7.5 l/min. Saravanan et al [10] realizaron estudios experimentales sobre el hidrógeno como complemento en motores diésel usando la técnica de recirculación de gases de escape. Los resultados arrojaron que el consumo específico de combustible se redujo sin la necesidad de utilizar la técnica de recirculación de gases al aplicar un flujo de 20 L/min de hidrógeno.…”

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.
