Abstract

Con el propósito de suprimir el paro abrupto y la fluctuación rotacional del motor después del arranque del motor en un motor de combustión interna capaz de usar un combustible que contiene alcohol, un PCM (50) corrige la cantidad de inyección de combustible de un inyector (11) cuando la cantidad de fluctuación en la velocidad de motor detectada por el sensor de velocidad de motor (SW2) durante la marcha lenta después del arranque del motor hasta que el sensor lineal de relación de aire-combustible (SW4) es activado es más grande que o igual a un umbral, la corrección es realizada incrementando la misma de la cantidad inicial de inyección de combustible después del arranque del motor a una cantidad de inyección de combustible que sería establecida si la concentración de alcohol en el combustible estuviera en un máximo o en una concentración dentro de un intervalo prescrito del máximo. Cuando la cantidad de fluctuación en la velocidad de motor detectada por el sensor de velocidad de motor (SW2) es más grande o igual al umbral una vez que es incrementada la cantidad de inyección de combustible, la cantidad incrementada de inyección de combustible es corregida al disminuir repetidamente la misma mediante cantidades de corrección más pequeñas que durante la corrección mediante el incremento hasta que la cantidad de fluctuación se vuelva menor que el umbral.
