GOMEZ-MONTOYA, Juan-Pablo; CACUA-MADERO, Karen-Paola; IRAL-GALEANO, Layrisser y AMELL-ARRIETA, Andrés-Adolfo. EFFECT OF BIOGAS ENRICHED WITH HYDROGEN ON THE OPERATION AND PERFORMANCE OFADIESEL-BIOGAS DUALENGINE. C.T.F Cienc. Tecnol. Futuro [online]. 2013, vol.5, n.2, pp.61-71. ISSN 0122-5383.
The effect of hydrogen enrichment was tested for a diesel-biogas dual fuel engine. The operation and performance characteristics, such as thermal efficiency, pollutant emissions and combustion parameters were determined. Experiments have been carried with a stationary compression ignition (CI) engine coupled with a generator in dual mode using a typical biogas composition of 60% vol. CH4 and 40% vol. CO2. For every load engine evaluated, the hydrogen concentration was varied from 5 to 20% H2 v/v. The results showed increases in peak pressure chamber up to 10.7 bar, and diesel substitution levels up to 80% under conditions of steady combustion without knocking. Also, thermal efficiency increases up to 16% and carbon monoxide emissions decreases up to 13% at full load, and 20% of hydrogen in engines operating in diesel-biogas dual mode.
