An attempt is made to compare usage of different biomass to generate producer gas and then to study the performance and emissions from a dual fuel engine run on diesel and producer gas from different biomass. The experiments are conducted at different fuel injection pressures. The open top, down draft gasification system is used to generate producer gas through bio-gasification process. A compression ignition engine was allowed running on fossil diesel (FD), fossil diesel and producer gas (FD+PG) dual fuel mode. In dual fuel mode, the producer gas from different biomass viz., babul wood, mango wood and casuarinas wood used each time during experimentation. The emission levels for each mode were measured. The dual fuel mode was found environmentally benign in terms of emissions; nitrous oxides (NOx) and smoke density (SD) levels are found to be much lower compared to conventional diesel engine exhaust.
Keywords: Dual-fuel engine, fossil diesel (FD), producer gas (PG), emissions.
