Effect of H 2 Addition via Solar-Driven Electrolysis on the Performance and Emissions of a CI Engine

Year: 2013

Type: article

Abstract: A vehicle-integrated photovoltaic system was used to produce a gaseous mixture of H2, O2 and steam, via alkaline electrolysis , for aspiration into an indirect-inject ion compression-ignition engine for the purpose of reducing soot opacity and hydrocarbon emissions. Aspiration of 0.516 ± 0.007 L/ min of the H2-O2-steam mixture produced through electrolysis of aqueous potassium hydro xide was found to reduce soot opacity, hydrocarbon emissions and particulate matter during part-load dynamo meter tests. Performance imp rovements under full-load conditions were observed. Ho wever, part-load performance at various engine speeds was found to decrease due to pre-mature auto-ignit ion of the aspirated gas.
