Abstract

Procedimiento para reducir la cantidad de combustible en vehículos equipados con inyectores de combustible y que se pueden abastecer con más de un combustible, que comprenden un paso de pilotaje de uno o más inyectores (3) con una presión real pr, a través de una unidad de control (1) y una bomba de alta presión (2), en donde la unidad de control (1) recibe una señal entrante de presión de retroalimentación entrante Pf desde un sensor de presión (4) caracterizado en que se concibe un paso de emulación del sensor de presión (4) que consiste en alterar la función de transferencia de un bucle de retroalimentación sobre el que se ubica el sensor de presión (4) de conformidad con la ley: Pf=pr • k(pv), en donde pv son parámetros de control de motor tipicos k(pv) es una función de los mismos, con k(pv)>1, es decir, Pf=pr> y pr = pt / k(pv), es decir pr=pt en donde pt es la presión objetivo de dicha unidad de control (1).
