Title Impact of Low Octane Hydrocarbon Blending Streams on the Knock Limit of 'E85.'
Publication Date Apr 2013
Media Count 11p
Personal Author B. H. West J. P. Szybist
Abstract Ethanol is a very attractive fuel from an end-use perspective because it has a high chemical octane number and a high latent heat of vaporization. When an engine is optimized to take advantage of these fuel properties, both efficiency and power can be increased through higher compression ratio, direct fuel injection, higher levels of boost, and a reduced need for enrichment to mitigate knock or protect the engine and aftertreatment system from overheating.
