Biokomponentidega fossiilsete mootorikütuste kasutamisel ja hoiustamisel on teatud
piirangud. Käesoleva töö eesmärgiks oli selgitada kirjanduse põhjal fossiilsete
biokomponentidega mootorikütuste kasutamisel ja hoiustamisel tekkivaid probleeme ning
kontrollida neid katseliselt. Töö käigus uuritakse erinevatelt mootorikütuste jaemüüjatelt
võetud kütuseproove - mootoribensiin E10 95, diislikütus B7 ning erimärgistatud
diislikütus B7. Mõõdetakse kütuseproovide olulisemaid kvaliteedinäitajaid nii enne kui
pärast 6-kuulist hoiustamisperioodi ning võrreldakse tulemusi proovide
vastavussertifikaatidel antud tulemustega ja standarditega kehtestatud nõuetega. Saadud
katsetulemustest selgus, et mitmed biokomponentidega fossiilkütuste kvaliteedinäitajad
halvenesid. Mootoribensiin sidus hoiustamisel endaga vett, diislikütustel oli peamiseks
probleemiks sademe tekkimine. Pool aastat õhutihedalt suletud metallkanistrites
hoiustatud biokomponentidega mootorikütused enam sihtotstarbeliselt kasutamiseks ei
sobi.
There are certain restrictions on the use and storage of fossil fuels with biocomponents. The aim of this work was to elucidate the problems arising from the use and storage of engine fuels with biocomponents on the basis of the literature and to test them experimentally. In the course of the work, fuel samples taken from different fuel retailers are examined - gasoline E10 95, diesel fuel B7 and special-purpose diesel fuel B7. The most important quality parameters of the fuel samples are measured both before and after the 6-month storage period and the results are compared with the requirements established in the standards and values on the certificates of conformity. The experimental results showed that several quality indicators of fossil fuels with biocomponents deteriorated. Gasoline absorbed water during storage, while diesel fuels had the main problem of precipitation. Fuels with biocomponents stored in hermetically sealed metal canisters for half a year are no longer suitable for their intended use.
