Abstract: A choke valve regulator means for internal combustion engines is provided with a diaphragm box containing a diaphragm arranged capable of opening or closing the choke valve. The diaphragm box is connected to a source of vacuum by a suction conduit having a check valve and a orifice. A by-pass passage to allow air to enter the diaphram box is connected to the suction conduit and the by-pass passage is controlled by a solenoid switch valve so that the diaphragm will be operated to open the choke valve when the engine is warmed up and the vehicle reaches a certain speed.

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.

Abstract: Choke valve opening and timing of the fast idle cam of a carburetor are set so that a certain angular difference is provided therebetween with the fast idle means kept operative for some time after the choke valve has fully opened. Engine idling during warmup is sufficiently stabilized for emission control, thus contributing to prevention of atmospheric pollution.

Abstract: In providing a separate supply of fuel to an internal combustion engine when it is started up from a cold condition or as it idles following a cold start up, an additional supply of fuel is withdrawn from the engine carburetor float chamber and is passed through a valve operated fuel well into a fuel chamber. The fuel well is opened when the intake manifold of the engine is at atmospheric pressure for passing fuel into the fuel chamber. A fuel line connects the fuel chamber to the venturi tube for supplying fuel to the engine and a branch pipe, communicating with the fuel line, adds air to the fuel as it is directed into the venturi tube. The passage of fuel through the fuel line is discontinued in response to a temperature sensing arrangement which checks the engine temperature and, when a predetermined temperature level is reached, cuts off the flow through the fuel line to the venturi tube.

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.
