Abstract

En un motor de combustible flexible que puede utilizar combustible que contiene alcohol como combustible que es quemado en un cilindro (11), la relación de compresión geométrica se ajusta a 12 o más, el motor se pone en marcha mediante el uso de combustible que contiene alcohol, una temporización de cierre de válvulas de admisión en un tiempo de arranque del motor se ajusta a un lado de ángulo adelantado que una primera temporización de referencia (L1) que es una temporización que corresponde a una posición de ángulo más retrasado de las temporizaciones de cierre de válvulas de admisión que pueden poner en marcha el motor en la quema de combustible de 100% de alcohol en el cilindro a una primera temperatura de admisión, y se ajusta a una temporización en un lado de ángulo retrasado que una segunda temporización de referencia (L2) que es una temporización que corresponde a una posición de ángulo más adelantado de las temporizaciones de cierre de válvulas de admisión que pueden evitar la pre-ignición en la quema de combustible de 100% de gasolina en un tiempo de arranque del motor a una segunda temperatura de admisión.
