Lubricant Viscosity Impact in Fuel Economy: Experimental Uncertainties Compensation
Abstrak
Climate constraints impose greenhouse gas emissions mitigation and the passenger cars have considerable contributions to give it. To improve engine efficiency of vehicles equipped with conventional powertrains, many technologies are available but with limited individual contribution. The experimental assessment of some technology regarding fuel economy measurement results is sometimes lower than test uncertainties. This study proposes a methodology to compensate the fuel economy for two test uncertainties: vehicle speed variations and battery recharging. The proposed method can be applied when investigating the effects of different vehicle design changes, including engine powercell design, in this work, the proposed method is demonstrated on the test of oils with two different viscosities, which allows a more detailed analysis. Applying the proposed methodology to experimental results changed from a raw 1.3% reduction in fuel consumption measured in the combined cycle to 2.9% compensated by these two uncertainties considering a vehicle numerical simulation model, a more plausible and reliable result.
