Abstract

Se proporcionan métodos y sistemas para suministrar combustible gaseoso a modo de inyecciones múltiples de combustible divididas en una carrera de admisión, una carrera de compresión y/o una carrera motriz para acelerar el calentamiento del catalizador de escape durante un arranque en frío del motor. El combustible inyectado en la carrera de admisión y la carrera de compresión se enciende y combustiona. Las inyecciones de combustible en la carrera motriz se combustionan en el orificio de escape para aumentar la temperatura de escape y la presión para lograr un encendido más rápido del catalizador.
