ABSTRACT:
The induction tube of an internal combustion engine is provided with a bypass conduit which feeds additional fresh air to the induction tube downstream of the carburetor and the main throttle plate. The flow through the bypass is controlled by a pneumatic control valve which is actuated by selective admission of a mixture of pressures taken from the main induction tube and from ambient sources. The selection takes place on the basis of transducer signals related to engine conditions which are processed by a regulator.
