Abstract

An improved throttle body fuel injection system having a single electrically controlled type of fuel injector in combination with a throttle bypass air circuit to provide favorable fuel preparation at substantially closed-throttle positions such as idle and deceleration while providing good cylinder-to-cylinder air/fuel distributions at wide-open-throttle. Fuel is introduced downstream of the throttle at idle and upstream of the throttle at full load.
