Abstract
An intake manifold and an exhaust manifold, both for use with an internal combustion engine, are provided with a common wall for transmission of heat from the hot exhaust gases to the air-fuel mixture in the intake manifold. A movable baffle is provided for varying the amount of heat transfered to the air-fuel mixture, and the operation of this baffle is controlled by a first device responsive to ambient temperature outside said manifolds, and also by a second device responsive to the intensity of intake vacuum pressure. The baffle may be mounted in either manifold and may be mounted to swing or slide with respect to the stationary heat transmitting wall which separates the manifolds.
