Effect of additivized biodiesel blends on diesel engine performance, emission, tribological characteristics, and lubricant tribology
Abstract: This research work focuses on investigating the lubricity and analyzing the engine characteristics of diesel–biodiesel blends with fuel additives (titanium dioxide (TiO2) and dimethyl carbonate (DMC)) and their effect on the tribological properties of a mineral lubricant. A blend of pal...

| Summary: | Abstract: This research work focuses on investigating the lubricity and analyzing the engine
characteristics of diesel–biodiesel blends with fuel additives (titanium dioxide (TiO2) and dimethyl
carbonate (DMC)) and their effect on the tribological properties of a mineral lubricant. A blend
of palm–sesame oil was used to produce biodiesel using ultrasound-assisted transesterification.
B30 (30% biodiesel + 70% diesel) fuel was selected as the base fuel. The additives used in the current
study to prepare ternary fuel blends were TiO2 and DMC. B30 + TiO2 showed a significant reduction
of 6.72% in the coefficient of friction (COF) compared to B30. B10 (Malaysian commercial diesel)
exhibited very poor lubricity and COF among all tested fuels. Both ternary fuel blends showed a
promising reduction in wear rate. All contaminated lubricant samples showed an increment in COF
due to the dilution of combustible fuels. Lub + B10 (lubricant + B10) showed the highest increment
of 42.29% in COF among all contaminated lubricant samples. B30 + TiO2 showed the maximum
reduction (6.76%) in brake-specific fuel consumption (BSFC). B30 + DMC showed the maximum
increment (8.01%) in brake thermal efficiency (BTE). B30 + DMC exhibited a considerable decline of
32.09% and 25.4% in CO and HC emissions, respectively. The B30 + TiO2 fuel blend showed better
lubricity and a significant improvement in engine characteristics. |
