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 pre-encendido a baja velocidad (LSPI) que tiene uno o más de una amidina, o un beta-amino alcanol que tiene la estructura (ver Fórmula). R1, R2, R3 y R4 se seleccionan cada uno independientemente de hidrógeno, anillo aromático y un grupo alquilo de C1-C20 y R5 es hidrógeno o un alcohol que tiene la estructura -(CH)R6-OH. R6 es hidrógeno, un grupo alquilo de C1-C10 o un grupo alquenilo de C1-C10, o una sal del mismo.
