The optimization of passenger car efficiency is an important contribution to GHG emissions mitigation. This global warming concern pushing technological solutions reduce vehicle fuel consumption and consequently CO2 emissions. In this work, the impacts engine lubricants with lower viscosity friction modifier additive in a light-vehicle spark ignition were numerically simulated experimentally validated. substitution baseline 5W40 lubricant by 5W20 proposal resulted 2.9% combined cycle. improvement enhanced 6.1% 0W16 modifier. A 1D simulation model based on temperature impact was developed presented good experimental correlation cycle for 5W20, showing 7% advantage than results. numerical 38% results that contains modifier, as not considered mathematical model.

Climate constraints impose greenhouse gas emissions mitigation, and passenger cars have considerable contributions to contribute this. To improve the engine efficiency of vehicles equipped with conventional powertrains, many technologies are available but limited individual contribution. The experimental assessment some technology regarding fuel economy measurement results is sometimes lower than test uncertainties. This study proposes a methodology compensate for two uncertainties: vehicle speed variations battery recharging. proposed method can be applied when investigating effects different design changes, including power cell design. In this work, demonstrated on oils: one 5W40, other 5W20, both without FM. Applying results, expected higher influence oil viscosity urban conditions could observed, presented much better correlation numerical simulation. compensation, savings using 5W20 in comparison 5W40 was 3.5% under 2.0% highways.
