Emission study on the outcome of DMC on neem bio-diesel-ignited diesel engine

ABSTRACT

This work aims to reduce the emissions of neem biodiesel in a single-cylinder CI engine. Ignition enhancement by blending di-methyl carbonate (DMC) at 5% to 10% (volumetric basis) with neem biodiesel is tested at different conditions at ambient conditions. DMC is blended at 5% and 10% on volume basis to neem biodiesel (BD100) and represented as DMC5BD95 and DMC10BD90. The complete emissions results were compared with diesel. Study revealed that the HC emissions from BD100, DMC5BD95, and DMC10BD90 are 7.3%, 8.1%, and 12.5% lower than diesel. Further, NO emissions from BD100, DMC5BD95, and DMC10BD90 are 9.81%, 8.43%, and 6.43% higher than diesel. However, upon adding DMC in DMC/BD blends result in better combustion and lower NO emission. Adding DMC (5-10%) to BD100 reduces the CO emissions by 4.1–12.7%. Additionally, the presence of DMC in DMC/BD blends produces an oxygen entertainment during combustion which lowers smoke opacity by 2.1–6.8%.
