Experimental investigation of performance, emission and combustion characteristics of olive mill wastewater biofuel blends fuelled CI engine

The current study investigates the opportunity of using olive mill wastewater (OMWW) as a renewable fuel in internal combustion engines. biofuel was made from hydrothermal conversion OMWW sub-/supercritical alcohol-water system. blended with pure diesel (designated B0). Three blends namely B10, B20 and B30 containing respectively 10%, 20% 30% by volume were tested. This paper focuses on experimental performance, emission characteristics engine partial replacement conventional fuel. All experiments performed constant speed (1500 rpm). load varied 20 to 100% full load. It is found that B10 blend offers best results, compared B30, terms performance pollutant emissions. Using showed lower levels for unburned hydrocarbons (12%), particulate matter (12%) carbon monoxide (26%) under high conditions, B20. Moreover, medium further reduced concentration pollutants such (55%) (65%) B30. In addition, use resulted thermal efficiency than Conversely, obtained highest even
