Ford / AVL study concludes mid-level ethanol blend attractive as a long-term future fuel for use in optimized engines in US

Green Car Congress

A study by a team from Ford Motor Company and AVL has concluded that a mid-level ethanol blend—greater than E20 but less than E40—appears to be attractive as a long-term future fuel for the US for use in engines optimized for the higher octane blend.

MECA report finds additional NOx emission reductions from new heavy-duty trucks achievable and cost-effective

Green Car Congress

CO 2 and NO x certification test data for heavy-duty diesel engines certified from 2002 through 2019. Source of data: US EPA (2019). This has resulted in higher catalyst loading per volume of substrate and led to downsizing of systems from those available in 2010. Chart: MECA.
