摘要

The performance assessment and vehicle verification of nano-alumina (Al2O3) engine oil (NAEO) were conducted in this study. The NAEO was produced by mixing Al2O3 nanoparticles with engine oil using a two-step synthesis method. The weight fractions of the Al2O3 nanoparticles in the four test samples were 0 (base oil), 0.5, 1.5, and 2.5 wt. %. The measurement of basic properties included: (1) density; (2) viscosity at various sample temperatures (20-80 °C). A rotary tribology testing machine with a pin-on-disk apparatus was used for the wear test. The measurement of the before-and-after difference of specimen (disk) weight (wear test) indicates that the NAEO with 1.5 wt. % Al2O3 nanoparticles (1.5 wt. % NAEO) was the chosen candidate for further study. For the scooter verification on an auto-pilot dynamometer, there were three tests, including: (1) the European Driving Cycle (ECE40) driving cycle; (2) constant speed (50 km/h); and (3) constant throttle positions (20%, 40%, 60%, and 90%). For the ECE40 driving cycle and the constant speed tests, the fuel consumption was decreased on average by 2.75%, while it was decreased by 3.57% for the constant throttle case. The experimental results prove that the engine oil with added Al2O3 nanoparticles significantly decreased the fuel consumption. In the future, experiments with property tests of other nano-engine oils and a performance assessment of the nano-engine-fuel will be conducted.
