The growing concern with environmental impact is a major drive in the search of alternatives to conventional fossil fuels. In this context, the blending of some quantity of biodiesel in diesel as a mean of reducing CO2 emission levels is being increasingly adopted. Brazil, for example, has determined a steady increase from 2% (2008) up to 12% (2020) in blend rate with no signs of stop or reversion on the tendency. Nevertheless, the expected impact of this fuel evolution on engine pollutant emissions raises questions on how an ageing Diesel fleet will react and how new calibrations may be efficiently developed. |
