Abstract

En un sistema que selecciona una leva grande como una leva de accionamiento en un tiempo de un inicio de un motor, cuando se emite una solicitud de detener el motor, se determina si existe un cilindro de leva pequeña para el cual se selecciona una leva pequeña como la leva de accionamiento; en un caso donde se determina que existe un cilindro de leva pequeña, se emite un comando de conmutación para conmutar la leva de accionamiento desde la leva pequeña a la leva grande; cuando se emite una solicitud de iniciar motor, se ejecuta nuevamente la determinación anterior; en un caso donde se determina que hay un cilindro de leva pequeña, el comando de conmutación es emitido a todos los actuadores solenoide nuevamente; además, el accionamiento del inyector de combustible es suspendido hasta que se completa la operación de conmutación de la leva de accionamiento para todos los cilindros.
