Abstract
A port fuel injection system for an automotive engine has injectors delivering fuel across an air gallery and through subsonic nozzles into the engine inlet manifold to provide enhanced mixing of air and fuel for combustion in the engine. A staged throttle mechanism operates a primary throttle controlling air flow through the air gallery and a secondary throttle controlling air flow directly into the manifold so that the air gallery provides substantially the entire air flow required for low speed light load engine operation.
