Abstract: This research examines the emissions characteristics of Compression Ignition (CI) engines utilizing a blend of diesel fuel and pyrolysis oil derived from discarded high-density polyethylene (HDPE) and coconut shells. The emissions from the CI engine, encompassing hydrocarbons (HC), carbon dioxide (CO2), carbon monoxide (CO) and nitrogen oxides (NOx), were systematically analysed utilising an RS232 exhaust gas analyser in conjunction with a smoke meter. The findings pertaining to the engine performance under loading conditions of 30%, 60% and 90% were derived from the utilization of a fuel mixture comprising pyrolysis oil blend in the ratios of HDPE oil, coconut shell oil and diesel, specifically 5:5:90, 5:10:85, 10:5:85 and 10:10:80. The emissions profile exhibited variability contingent upon the pyrolysis blending ratios employed. The CI engine operating with a fuel blend of 5:10:85 demonstrated a reduction in NOx and HC emissions. Concurrently, the emissions of CO and CO2 were decreased with the 10:5:85 and 5:5:90 blends, respectively, when compared to 100% Diesel fuel. The optimal fuel blend comprising a ratio of 5:5:90, integrated with nano-additives, aims to mitigate emission behaviour associated with the automotive industry. [ABSTRACT FROM AUTHOR]
