Abstract
A throttle body and an air control system that integrates the electronic engine control modules, sensors, actuators, and associated wiring on a throttle body is disclosed. In one version of the invention, there is provided a throttle body including a throttle body wall defining an airflow passage in the throttle body, a movable throttle plate that substantially conforms to the interior dimensions of the air flow passage, an engine control device (such as a sensor or an actuator) attached to the throttle body wall, and engine control electronics mounted to the throttle body wall in spaced apart relationship with the engine control device, the engine control electronics being electrically connected with the engine control device. In another version of the invention, there is provided an air control system including a throttle body having a wall defining a first airflow passage in the throttle body, a movable throttle plate substantially conforming to the interior dimensions of the first airflow passage, an air intake manifold having a wall defining a second airflow passage, the air intake manifold being attached to the throttle body such that the first airflow passage and the second …
