FUEL COMPOSITIONS CONTAINING PROPOXILATE |
摘要 |
<p>The invention relates to fuel compositions for internal combustion engines comprising a main quantity of a liquid hydrocarbon fuel and a pure portion of at least one propoxilate additive of formula (I), wherein n is an integer ranging from 10 to 20, and R1 represents a straight-chain or branched C8-C18 alkyl radical or C8-C18 alkenyl radical; optionally in combination with at least one detergent additive such as, for example, a polyalkylamine of formula (II) R2-NH2, wherein R2 represents a straight-chain or branched polyalkyl radical having a numerical average molecular weight ranging from approximately 500 to approximately 5000. The invention also relates to fuel additive compositions which contain propoxilates of formula (I) and optionally contai n additional additives such as said polyalkylamines of formula (II) used as intake valve cleaners.</p> |
