Summary:Methods and systems are described for controlling fuel injection in an engine equipped with a dual injector system including a port injector and a direct injector. A ratio of port injected fuel to direct injected fuel is adjusted based at least on intake valve temperature. The proportion of fuel port injected into a cylinder is increased as the intake valve temperature for the given cylinder increases to improve fuel vaporization in the intake port. Se describen métodos y sistemas para controlar la inyección de combustible en un motor equipado con un sistema de inyector dual que incluye un inyector en puerto y un inyector directo. Se ajusta una fracción de combustible inyectado en puerto contra combustible inyectado en forma directa en función de al menos la temperatura de la válvula de admisión. La proporción de combustible en puerto inyectado en un cilindro aumenta a medida que la temperatura de la válvula de admisión de un cilindro determinado aumenta para mejorar la vaporización de combustible en el puerto de admisión.
