Abstract: In a device operated in response to the pressure in the intake manifold of a gasoline engine, the interior of a housing is divided into an air chamber and a pair of vacuum compartments separated by a diaphragm. The vacuum compartments are connected by a small opening through the diaphragm. One of the vacuum compartments is connected to the intake manifold. A valve is mounted within the housing for regulating flow of atmospheric air through the air chamber to the intake manifold. The valve is connected to the diaphragm and variations in the pressure within the two compartments results in a displacement of the valve for changing the flow of secondary air into the intake manifold. In addition to the intake manifold pressure other engine conditions can be checked and used for supplying the secondary air.

Abstract: An intake manifold for an internal combustion engine utilizing a carburetor having dual passages includes a manifold housing which also has dual passages in communication with the carburetor dual passages. One of the passages in the manifold housing is heated in a positive manner to facilitate vaporization of fuel in the heated manifold passage, thereby improving operability of the engine during warm-up and also reducing the noxious components in the exhaust gas.
