Abstract (en)
[origin: DE19647554A1] The invention relates to an operating fluid which can be efficiently used for lifetime lubrication and cooling of an internal combustion engine. As basic liquid, said fluid contains a polyalkylene glycol obtained from ethylen oxide and propylen oxide and an additive compound, consisting of a) 0.012 -1.0 wt.% of a reaction product from diphenylamine and 2.4.4.-trymethylpentene; b) 0.01-1.0 wt.% of a pentaerythrite partially or totally esterified with an alkyl-substituting p-hydroxy propionic acid; c) 0.01-1.0 wt.% of a mono- or di-(C4-C8)alkyl phosphoric acid-(C10-C15) alkylamide; d) 0.01-1.0 wt.% of the triphenylthiophosphate; e) 0.01-0.1 wt.% of a tolutriazole aminoethylized with a straight chain or branched alkyl group with 2-10 carbon atoms and/or f) 0.01-0.1 wt.% of the 1H-benzotriazole.
