Effects on Fuel Consumption and Diesel Engine Deposits from Nano- Particle Oil Additive

摘要

This project evaluated the effects of a nano-particle additive when blended with MIL-PRF-46167D OEA-30 Arctic Oil as a baseline fluid. Baseline and additized oil were tested for CAT 1K/1N deposits, in-vehicle and dynamometer fuel economy, and lab tests for physical properties and wear metals. Results from the CAT 1K/1N test showed a positive impact on deposits when using the nano-particle additive. Results for both the in-vehicle and dynamometer fuel consumption testing did not indicate that there was a change in fuel consumption either when using the nano-particle additive, or from carry-over effects after changing back to MIL-PRF-46167D oil. High Temperature Benchtop Corrosion Testing produced results showing an increase in wear metal concentration, and copper corrosion appearance when utilizing the nano-particle additive.
