Graphene nanoparticle as an additives and its influence on pure diesel and biodiesel fuelled CIDI engine

ABSTRACT

In this experimental investigation, graphene nano additive was used at different proportions from 25 to 100ppm with an interval of 25ppm. It was then dispersed into the neat diesel and 20% Calophyllum inophyllum blend and its properties were determined. Further, experimentation was conducted for selected fuels in a CI engine. The discussions revealed that BTHE increased by 0.54 and 0.03% for CI20 with GNA of 25 and 50ppm. VE was decreased by 0.19, 0.32, 0.59, and 0.70%. EGT was decreased by 7.69, 7.57, 6.71, 6.81, and 7.55% for CI20 with GNA of 25 to 100 ppm. CO emissions were decreased by 12.8, 10.37, 8.71, and 1.65%, HC emissions were lessened by 72.44, 74.48, 75.5, and 76.5%, NO_x emissions were reduced by 19.34, 17.56, 19.53, and 16.88%, opacity reduced by 7.1, 5.13, 4.47, and 4.07% for CI20 with GNA of 25 to 100ppm. The maximum cylinder pressure was reduced by 0.76, 1.02, 1.55, and 0.36%, RPR was increased by 36.58%, 33.69%, 38.82%, and 35.33% for CI20 with GNA of 25 to 100ppm. 90% MFB was taken for all blends at the difference of approximately 1°CA from that of diesel. Therefore, CI20 with GNA proportions is a promising substitute for diesel fuel.
