Abstract (en)
[origin: WO0136799A1] The subject invention is a throttle body assembly having an elliptically shaped airflow passage and throttle valve such that the overall height of the throttle body is reduced. The air passage includes a contoured bore that allows the airflow passage to be fabricated to reduce the height of the throttle body. The throttle valve rotates between an open and closed position to regulate airflow through the airflow passage. The airflow passage includes a contoured shape and the throttle valve includes a periphery. The contoured shape is disposed in the airflow passage such that a predetermined distance between the edge of the throttle valve and the airflow passage is maintained for a predetermined amount of rotation of the throttle valve.
