| Abstract: | The
quasi-stationary (Q-S), spherically symmetric combustion of the isolated
multi-component droplets of oxygenated diesel fuel has been modelled using a variable mechanism, which has been developed and
validated against several independent data sets. The composition of three-component motor fuel,
consisting of fossil diesel (DF), rapeseed oil methyl ester (hereinafter RME; B100)
and dehydrated ethyl alcohol (DEA), closing to DF by its ignition delay
characteristic is established. Numerical simulation results show that in
contrast to RME, the additive of dehydrated ethyl alcohol to DF/RME blend tends
to increase a time of ignition delay. Striving for improving of the combustion
process strained by bigger volumes of fossil diesel being replaced by
oxygenated biofuels to meet ecological behavior and economical independence on
imported fuels, as well as simultaneously omitting any regulatory
adjustment, leads to combining of dehydrated ethyl alcohol and rapeseed oil
methyl ester to compound the conventional diesel fuel. |
