Abstract

En la presente se describe una composición de combustible que tiene (1) más de 50 % en peso de un combustible de hidrocarburo que hierve en el intervalo de gasolina o diesel y (2) una cantidad menor de un aditivo reductor de preencendido de baja velocidad (LSPI) que tiene una o más de una amidina, o un beta-amino alcanol que tiene la estructura . R1, R2, R3 y R4 se selecciona cada uno independientemente de hidrógeno, anillo aromático y un grupo alquilo C1-C20 y R5 es hidrógeno o un alcohol que tiene la estructura –(CH)R6-OH. R6 es hidrógeno, un grupo alquilo C1-C10, o un grupo alquenilo C1-C10, o una sal de este.Described herein is a fuel composition having (1) more than 50% by weight of a hydrocarbon fuel boiling in the gasoline or diesel range and (2) a lesser amount of a low speed pre-ignition reducing additive. (LSPI) that has one or more than one amidine, or a beta-amino alkanol that has 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.
