- In this study, Diesel Oxidation Catalyst (DOC) and Diesel Particulate Filter (DPF) after treatment systems integrated 3L diesel engine fueled with BDF20, BDF50, BDF100 biodiesel fuels and JIS#2 diesel fuel are experimentally analyzed at 100 Nm, 200 Nm and full load (294 Nm); while the engine speed and cooling water temperature are constant at 1800 rpm and 80 °C, respectively. The advanced thermodynamic analyses, such as environmental and enviroeconomic analyses with energy, exergy, sustainability, thermoeconomic and exergoeconomic analyses, are applied. It is found that; (i) Utilization of the DOC is effective to reduce the fuel consumption of the BDF50 fuel; while the DOC and DOC + DPF are effective for the BDF100 fuel. (ii) DOC + DPF is more effective for biodiesel fuels. (iii) DOC + DPF decreases the soot concentration of all fuels. (iv) The maximum efficiency is found for the BDF100 fuel. (v) DOC + DPF is generally good option to reduce the CO2 of the fuels, especially for the BDF20 and BDF50. (vi) DOC + DPF is more effective for the BDF20 and BDF50 biodiesel blends; while both of the DOC and DOC + DPF are effective for the BDF50 fuel for reducing the prices of the released CO2. (vii) All fuels are more sustainable at full load.
