•Maximum engine performance was obtained at 2000rpm for all fuel blends.•IRGALUBE 349 additive is enhances diesel engine performance.•Reduction of CO and NOx considerably using anti-corrosion additive except HC.•Engine wear decreases with using blended fuels with anti-corrosion additive. This study evaluates the effect of anti-corrosion additives such as 8% and 16% (vol.%) palm olein oil (PO) with ordinary diesel (OD) fuel on engine operation, emission behavior, engine part wear, and lubrication characteristics. This experiment was conducted on 4-cylinder and 4-stroke IDI diesel engine at different engine speed ranging from 1200 to 2800RPM with 30% throttle setting under full load condition. The properties of the palm olein oil blends meet the ASTM D6751 and EN 14214 standards. At 2000rpm, the experimental results revealed that the POD8A (0.2% Additive+8% PO+92% OD) and POD16A (0.2% Additive+16% PO+84% OD) blended fuels produced 0.5% and 0.51% higher brake power as well as 1.45% and 1.25% higher torque than same blends without additive, respectively. In comparison with ODF, the brake specific fuel consumption (BSFC) was found 1.8% and 3.1% higher for POD8A and POD16A blends, respectively. Anti-corrosion additive is found more effectual in enhancing the engine performance as such additive helps in timely ignition for complete burn in the combustion chamber. The results from engine emission indicated that POD8A and POD16A blended fuel reduced CO emissions by 11% and 6.6% and NOx emission by 2.5% and 1.09%, respectively in compared with OD fuel. Although HC emissions for all blended fuel and OD fuel increased at higher engine speed, the average HC emissions of all blended fuel were not higher than OD fuel. The application of anti-corrosion additives in POD blends reduced ferrous (Fe) wear debris concentration (WBC) by 17.3%. The reductions in WBC were about 16.1%, 10.8%, and 19.3%, 17.6% for copper (Cu) and aluminum (Al), respectively. An exception was lead (Pb) which yielded higher WBC for all POD blended fuels in compared with OD fuel. Finally, it can be concluded that palm olein oil with additives gives better engine performance, reduces unnecessary exhaust emissions and wear debris concentration of engine parts.
