Abstract

EN UN DISPOSITIVO PARA CONTROL DE DESCONEXION DE UNA VALVULA DE INYECCION EN MOTORES DE COMBUSTION INTERNA EN VEHICULOS INDUSTRIALES, CON MEDIOS PARA EL REGISTRO DE LA TEMPERATURA DEL CATALIZADOR DEL GAS DE EXHAUSTACION, SE DISPONE DE ELEMENTOS PARA EL SUMINISTRO DE LA CANTIDAD DE INYECCION NECESARIA PARA LA ELEVACION DE LA TEMPERATURA DEL CATALIZADOR DE GAS DE ESCAPE MOMENTANEO. ESTA CANTIDAD DE INYECCION PREVIAMENTE DADA SE INYECTA DURANTE UN CONTROL DE DESCONEXION AL MENOS PARCIALMENTE, CUANDO LA TEMPERATURA DEL CATALIZADOR DE GAS DE EXHAUSTACION SE ENCUENTRA POR DEBAJO DE UN VALOR UMBRAL PREVIAMENTE DADO.
