Abstract: An internal combustion engine including a carburetor. The internal combustion engine includes a choke valve disposed within the carburetor, and a choke lever interconnected with the choke valve for movement with the choke valve. The engine also includes a throttle valve disposed within the carburetor and a throttle lever interconnected with the throttle valve for movement therewith. An intermediate lever is disposed between the throttle lever and the choke lever for movement with the choke and throttle levers. In one embodiment, the engine includes a connecting link coupled between the choke and intermediate levers, the connecting link movable with movement of the choke lever such that movement of the choke lever is translated into movement of the intermediate lever.

Abstract: A choke valve is controlled finely suited to the running state of an engine. A throttle valve 8 and a choke valve 9 are provided in series on an intake pipe 6, and the opening degree of the choke valve 9 is controlled by a stepping motor 11. A choke valve opening degree upon start of engine (start opening degree) is determined depending on the engine temperature. The start opening degree judging unit 27 judges whether the start opening degree is closer to the fully closed side or fully opened side. The motor initializing unit 28 initializes the stepping motor 11 at the fully closed side or the fully opened side if the start opening degree is at the fully closed side or the fully opened side, respectively. After choke release, a driving signal in a specified number of steps is issued periodically.

Abstract: An automatic choke for a small internal combustion engine uses an air vane responsive to an air flow created by a radial fan to position the choke valve during engine starting. A return spring or gravity may be used to reset the automatic choke after the engine has been stopped. The automatic choke includes a thermally-responsive device that keeps the choke at least partially open during hot restarts of the engine.

Abstract: A mounting arrangement for an accelerator pump and a choke actuation mechanism, which are used in conjunction with a plurality of charge formers, minimizes the girth of the engine while making these components more accessible and easing assembly. An actuator and a choke solenoid of the choke actuation system are mounted proximate to one another and partially between adjacent induction pipes of an induction system. This position allows these components to be located on an exterior side of the induction system without interfering with the protective cowling of the motor. The accelerator pump is mounted at the end of a series of charge formers, proximate to a throttle linkage which controls throttling devices of the charge formers. This position of the accelerator pump eases the installation of this component without increasing the girth of the engine.

Abstract: An automatic priming system for an outboard marine engine includes a pneumatic cylinder operably connected to the recoil pulley of the engine. The pneumatic cylinder is charged by the rotation of the pulley and the increased pressure is communicated to a second pneumatic cylinder that is operably connected to the primer button of the engine. Thus, rotation of the recoil pulley results in an automatic depressing of the primer button.

Abstract: While an exhaust gas sensor having an output characteristic linear with respect to the concentration of a specific component in exhaust gases from an internal combustion engine, the opening of an automatic choke valve is controlled in response to the degree of warming-up of the engine. From the time of activation of the exhaust gas sensor to the time of completion of warming-up of the engine, the automatic choke valve and an air-fuel ratio control valve arranged in an air passage bypassing a throttle valve in an intake passage of the engine, are driven so as to achieve a desired air-fuel ratio, respectively, when the difference between the desired air-fuel ratio and actual one is larger than a predetermined value, and when the difference is smaller than the predetermined value. After completion of warming-up of the engine, the air-fuel ratio control valve is driven in response to operating conditions of the engine so as to achieve the desired air-fuel ratio.

Abstract: A selector valve device for controlling the opening and closing of a fluid passageway in response to both the input current signal and the ambient temperature, especially used for a carbureter outer vent controller of vehicle engines. The valve device is equipped with a metal heat transfer member which contacts with both the core member of an electromagnet for supplying the input current signal and a temperature sensing spring for biasing the valve in the direction for opening the valve, thereby to transfer the heat generated by excitation of the electromagnet to the temperature sensing spring so that the difference between the temperature in the carbureter float chamber and the ambient temperature sensed by the spring is reduced.

Abstract: An apparatus for controlling the opening degree of a throttle valve during starting and warming up of an internal combustion engine, has the following constituents: a fast idle cam which operates to progressively decrease the opening degree of the throttle valve as the warming up of the engine proceeds; a starting cam provided separately from the fast idle cam and adapted to maintain a large opening degree of the throttle valve; a first means for bringing, while the engine is not operating, the starting cam into operative position for holding the throttle valve, in response to a throttle opening operation; and a second means for releasing, when a predetermined engine temperature is reached after the starting of the engine, the holding of the throttle valve by the starting cam and insteadly bringing the fast idle cam into operation for controlling the opening degree of the throttle valve.
