摘要: Disclosed is a lubricating engine oil composition comprising a lubricating oil base stock as a major component, and at least one metal or metalloid hydrogen atom donor compound. Also disclosed is a method for preventing or reducing low speed pre-ignition in a direct injected, boosted, spark ignited internal combustion engine, and the use of at least one metal or metalloid hydrogen atom donor compound in a lubricating engine oil composition for preventing or reducing low speed pre-ignition in a direct injected, boosted, spark ignited internal combustion engine.

摘要: Fuel and lubricant compositions are provided that contain a primary low-speed pre-ignition (LSPI)-reducing additive comprising (i) an amino additive, (ii) an amine additive, (iii) a triazole additive, (iv) a benzamidinium additive, (v) a benzoxazole additive, or (vi) a N═C—X motif additive. Methods for preventing or reducing low speed pre-ignition events in spark-ignited engines using these compositions are also provided.

摘要: Disclosed is a lubricating engine oil composition for use in down-sized boosted engines comprising a lubricating oil base stock as a major component, and at least one silane-containing compound. Also disclosed is a method for preventing or reducing low speed pre-ignition in a direct injected, boosted, spark ignited internal combustion engine, and the use of at least one silane-containing compound in a lubricating engine oil composition for preventing or reducing low speed pre-ignition in a direct injected, boosted, spark ignited internal combustion engine.

摘要: Disclosed herein is a fuel composition having (1) greater than 50 wt % of a hydrocarbon fuel boiling in the gasoline or diesel range and (2) a minor amount of a low-speed pre-ignition (LSPI)-reducing additive having one or more of an amidine, or a beta-amino alkanol having the structure R1, R2, R3, and R4 are each independently selected from hydrogen, aromatic ring, and a C1-C20 alkyl group and R5 is hydrogen or an alcohol having the structure —(CH)R6—OH. R6 is hydrogen, a C1-C10 alkyl group, or a C1-C10 alkenyl group, or a salt thereof.
