Off-grid diesel generators enhanced performance using photovoltaic powered on-board HHO generation: Experimental validation

The fear of fuel depletion necessities the integration of energy saving methodologies for electric power generation. Diesel engines are common for back-up/standby electric power generation units. Being compression-ignition based, in contrary to gasoline engines, the enrichment of the air intake of diesel engines with Hydrogen improves the fuel burning process, leading to better fuel consumption. Wet/dry cells, performing water electrolysis, are the most economic solutions for on-board Hydrogen generation, where the Dry Cells are of better performance. Commonly, these cells are DC-powered from a controlled rectified generator output voltage offering unsatisfactory minimal improvement. This paper presents a diesel engine fuel consumption improvement technique based on injecting in the engine Hydrogen, generated on-board using photovoltaic (PV) powered Dry-cell. The proposed technique is validated experimentally where the results clarify remarkable enhancement from fuel consumption aspect.
