Abstract
Abstract
Alternative fuels have been developed for standard spark ignition engines. The fuels, which contain generic bio-components, maintain all the advantages of ethanol, i.e. the ability to increase considerably the octane number of gasoline and to reduce the amount of harmful pollutants in the exhaust emissions of engines operating on such blends. In contrast with ethanol the new fuel components do not increase the vapour pressure of gasoline-ethanol blends, have a better tolerance to water, and do not increase the fuel consumption. The bio-component-based fuels also compare favourably with mineral-sourced octane boosters such as methyl tert-butyl ether. Additionally reformulation of the base gasoline becomes unnecessary.
