Abstract
The performance and emissions of diesel engines using titanium oxide (TiO2) nanoparticles and carbon nanotube (CNT) as fuel-based nanoparticle additives in the plastic pyrolytic oil (PPO)-diesel mixture (B30) were investigated in this work. The fuel mixes were prepared by adding 100 ppm TiO2, 100 ppm CNT, and their combinations to B30, then mechanically stirring the mixtures at high speed and stabilizing them in an ultrasonic bath. Brake specific fuel consumption (BSFC), brake thermal efficiency (BTE), power, torque, carbon monoxide (CO), carbon dioxide (CO2), hydrocarbon (HC), and oxygen (O2) exhaust gas were all evaluated. The engine was run at full load in the 900 to 2400 rpm range. As CNT was added to B30, BTE increased by 7.01 than that of blank B30. Simultaneously, BSFC of B30 dropped with the addition of CNT, TiO2 and their combination, with B30-CNT showed the greatest reduction of 16.00 than that of blank B30. CO2 and HC emissions can be reduced by adding CNT, TiO2, and their combinations with B30. However, as compared to B30, B30-CNT emits the least CO2 and HC, with 30.93 and 82.77 reductions, respectively. As a result, using CNT alone to increase performance and reduce emissions is the best option. © 2021, Malaysian Tribology Society (Mytribos). All rights reserved.
