Abstract
A method and apparatus for controlling the ratio of ambient air to recirculated gases in an internal combustion engine, wherein an gas injector includes a intake air conduit defining a ambient air flow path, an actuator connected to the intake air conduit, a recirculated gas conduit operatively coupled and disposed within the intake air conduit defining a recirculated gas flow path and a valve apparatus operatively coupled to the intake air conduit and recirculated gas conduit. The valve apparatus includes; a shaft, a throttle valve coupled to the shaft and in fluid communication with the ambient air flow and a recirculated gas valve coupled to the shaft in fluid communication with the recirculated gas flow. The shaft rotates one of the throttle valve and the recirculated gas valve independent of the rotation of the other one of throttle valve and said recirculated gas valve.
