Abstract:
A fuel composition for a direct fuel injected gasoline engine comprising, a method for improving performance of fuel injectors and a method for cleaning fuel injectors for an internal combustion gasoline engine. The fuel composition includes a major amount of fuel and a minor, effective amount of a quaternary ammonium salt having a thermogravimetric analysis (TGA) weight loss of greater than 50 wt.% at 350° C. The amount of quaternary ammonium salt present in the fuel is sufficient to improve performance of the direct fuel injected engine having combusted the composition compared to the performance of such engine having combusted a fuel composition that does not contain the quaternary ammonium salt.

Abstract:
The present invention relates to diesel fuel and lubrication oil defoaming agents, and crude oil demulsifiers, as well as methods for using same. In particular, the defoaming agents and demulsifiers are comprised of copolymers which have structures constituting a backbone of polysiloxane onto which is grafted an organic group. These structures comprise a polymer of the formula MDxD'yD"zM, where M is O.5Si(CH3)3, D is a OSi(CH3)2, D' is OSi(CH3)R, D" is OSi(CH3)R', R is a polyhydric C6-C28 organic group, R' is a phenol derivative or a long chain aliphatic group or polyethers, z is between 0 and 80, x+y+z is between 10-200, x/z is >/= 1, and x/(y+z) is between about 1 and about 5, or formula M'DaM' where M' is O.5Si(CH3)2R, a is between 4-10, and R and D are the same as defined above.
Abstract:
Emissions of pollutants from diesel engines (10) are reduced by a regimen for catalytically treating engine exhaust and, preferably, also the combustion of the fuel. The balance point of a diesel trap (30) is reduced to permit more efficient regeneration, preferably self-regeneration, while also reducing emissions of carbon monoxide and hydrocarbons by a combination of mechanical devices and fuel additives. The regimen requires the introduction of from 0.05 to 1 ppm of a platinum group metal catalyst (based on the volume of fuel combusted) into the particulates, by introducing at least half of the platinum group metal catalyst (50) directly into the hot exhaust gases (52, 20). Preferably, the platinum group metal catalyst is employed with a combustible organic liquid to aid in either progressively loading the trap (30) with the combustible organics or to combust in the hot combustion gases to facilitate burning of the particulates on the trap (30) for more effective regeneration. The judicious selection and use of an auxiliary catalyst metal (e.g., copper), preferably adding at least half of its total to the fuel as a fuel additive, is a preferred part of the regimen to achieve the lowest trap balance point.
Abstract:
Oil-soluble dispersant additives are disclosed. The additives comprise the reaction product of a functionalized 1-butene copolymer and at least one nucleophilic reactant selected from amines, amino alcohols, alcohols, and reactive metal compounds. The functionalized copolymer has within its structure at least one acyl functional group selected from the group consisting of C4 to C10 dicarboxylic acids and derivatives thereof and C3 to C10 monocarboxylic acids and derivatives thereof. The 1-butene copolymer is derived from 1-butene and at least one other alpha -olefin of the formula CH2=CHR', wherein R' is methyl or a C3 to C12 linear or branched alkyl group. The copolymer has a number average molecular weight of at least about 700, a molecular weight distribution of less than 5, and ethenylidene groups terminating at least about 30 % of all polymer chains. The dispersant additives are useful in oleaginous compositions including lubricating oil compositions and concentrates and fuel compositions.
