Influence of fuel components, injection parameters and nano blends on CRDI engine characteristics fuelled with palm and jatropha methyl esters

Abstract

The present study emphasises on the influence of fuel components and multiple injection parameters on engine characteristics of CRDI engines fuelled by B100 blends of jatropha, palm methyl esters and their nano-blends (MWCNT). At full load conditions, in regard to combustion characteristics, at 10⁰ bTDC and 600 bar, POMWCNT exhibited a 4.5% and 2.4% decrease of NHRR, in the case of performance, JOMWCNT demonstrated a 2.4% BTE increase,1.5% decrease of BSFC at 10⁰ bTDC 800 bar and subject to emissions, for POMWCNT there is a further decrease of 6.66% CO, 0.449% NO_x and 9.4% smoke at 10⁰ bTDC, 5.88% CO, 0.736% NO_x at 700 bar, 3.27% smoke opacity at 800 bar. Therefore, the present study shows that the CRDI engine characteristics could be enhanced by varying injection parameters and nano blending. Additionally, it also reflects on the impact of fuel components on engine characteristics.
