Ford researchers suggest using higher ethanol blends to boost the minimum octane number of regular-grade gasoline

Green Car Congress

Using higher volume blends of ethanol to leverage the alcohol’s inherent high octane rating to produce ethanol-gasoline blends with higher octane numbers could yield “substantial societal benefits”, according to a team of researchers from Ford Motor Company. Anderson and colleagues suggest in a new paper published in the journal Fuel.

Concept: Downsized and Supercharged Hybrid Pneumatic Engine for 30%+ Reduction in Fuel Consumption

Green Car Congress

Schematic of downsized and supercharged four-stroke hybrid pneumatic spark injection engine. The reduction in fuel consumption is obtained mainly through enabling the effective use of a heavily downsized engine, rather than from regenerative efficiency. The major part of this gain is due to downsizing the engine. Earlier post.).

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. These include: Lower energy content than that of gasoline. Earlier post.)
