Environmental Impact Reduction using Diesel and Biogas blends in Dual-Fuel CI Engine: An Ecological Approach

The present paper analyzes how raw biogas can
be used to substitute diesel (partial modifications) in a
compression ignition (CI) engine. Bio gas was insufficient to
sustain the compression ignition and therefore, air-biogas mixer
was employed to enable the operation on dual-fuel. Constant
compression ratio and constant speed, as well as varied loads,
have been experimented in three fuel modes as the pure diesel,
the diesel with biogas of 10 and the diesel with biogas of 30
percents. The originality of the research is the highest
comparative system of low and medium level of substitution
under the same operating conditions. Findings indicate that B10
and B30 have diesel fuel consumption reductions with B30
experiencing major diesel fuel consumption reduction in
quantities of smoke, and reductions in CO emissions and B10
experiencing greater reductions in NOx and CO emissions.
These findings indicate that dual-fuel biogas-diesel engines can
reduce fossil fuel use and fossil fuel emission to achieve
sustainable energy changeover and cleaner transportation
