Využití biobutanolu ve vznětových motorech a jeho vliv na parametry motorové nafty
Klíčová slova:butanol, ethanol, motorová nafta, destilační křivka, mazivost
Biobutanol can replace bioethanol used in gasoline and it can be also added as admixture to diesel oil. Although butanol is more often considered for use in gasoline, this article evaluates blends of butanol with diesel oil from the viewpoint of fuel properties and technical adjustment of the fuel system. The EN 590 standard for diesel fuel is well maintained by a single butanol amount parameter in diesel oil without other additives. The obtained parameters of diesel oil with the butanol content below 30 vol.% are suitable for unmodified engines.
