Abstract:
A fuel composition is disclosed comprising a major portion, in the order of 94% by weight, of a liquid fuel such as gasoline mixed with a minor portion, in the order of 6% by weight, of particulates generally similar to particulates of polyvinyl alcohol of about 10 to 40 microns in size. These particulates are suspended in and are small enough to be metered along with the liquid fuel in a conventional automobile carburetor and when this fuel composition is burned in the combustion chamber of internal combustion engines, the particulates function as nuclei for droplets of the carrier fuel which act as combustion promotion agents in the dry vapor charge at the instant of combustion to intensify the burning process to extend the low lean limit of consistent and regular engine firing and to reduce NO.sub.x. A similar composition of liquid fuel in open flame combustion results in a much improved heat transfer efficiency of the energy in the fuel.
Abstract:
Hydroxylated polymeric additives useful as additives, for example as dispersants for lubricants and hydrocarbon fuels, and multi-functional dispersant-viscosity index improvers for lubricants, can be prepared by the reaction of metal salts of polyols with a halogen containing olefin polymer, particularly ethylene containing polymers, such as: the halogenated terpolymer of ethylene, a C.sub.3 to C.sub.18 straight or branched chain .alpha.-olefin and a C.sub.5 to C.sub.14 acyclic or alicyclic nonconjugated diolefin; a terpolymer of ethylene, a C.sub.3 to C.sub.18 alpha olefin and a C.sub.5 to C.sub.14 halogen-containing olefin; halogenated copolymers of ethylene and a C.sub.3 to C.sub.18 straight or branched chain .alpha.-olefin; etc.
Abstract:
Combinations of (A) polymers of C3-C4 olefins having a molecular weight in the range of about 400 to about 1400; and (B) polyoxyalkylene compounds of the formula
wherein R is an alkyl group of 1 to 20 carbon atoms and wherein x has an average value of 4 to 20; are effective as anti-icing additives, as carburetor detergents and in some instances as intake valve deposit modifiers.
Abstract:
An additive having detergency and lubricity properties for incorporation in petroleum hydrocarbon and petroleum hydrocarbon compositions containing said additive. The additive is the condensation product of a polyetherpolyester polyol containing from 2 to about 12 hydroxyl groups and a monocarboxylic acid wherein about 85-100 percent of the hydroxyl groups of the polyol are esterified by condensation with the monocarboxylic acid. The additive is generally incorporated in hydrocarbon fuels and hydrocarbon lubricating oils, but its greatest utility is in hydrocarbon lubricating oils. The preferred lubricating oil composition is a two-cycle engine oil comprising a major proportion of a hydrocarbon lubricating oil and a minor proportion of the additive of this invention.
