    摘要： A four barrel carburetor is provided with apparatus that operates automatically during predetermined engine deceleration operating conditions to crack open the secondary induction passage throttle valve to supply a quantity of fuel and air to the engine that is supplemental to that being supplied through the primary induction system, to decrease the output of harmful emissions by causing a cleaner burn.

    摘要： A downdraft type carburetor has an idle system discharge port that is straddled by the normal idle speed and closed throttle positions of the throttle valve so as to permit idle speed fuel and air flow in one position and no flow in the other position; a third beyond normal idle, or fast idle speed position is provided for engine startup; the three positions are controlled by a servo operatively engaging the throttle valve; the servo operation is controlled by intake manifold vacuum to initially close the throttle valve upon engine shut off, with a subsequent return of the throttle valve to its fast idle position for engine restarting, or to return the throttle valve to a normal idle position upon release of the vehicle accelerator pedal during engine operation.

    摘要： Apparatus for automatic control of the throttle valve of an internal combustion engine comprises an adjusting mechanism for the throttle valve idle position operated by the negative pressure in an air inlet pipe via a negative pressure operated mechanism so that the idling position of the throttle valve can be adjusted. A temperature sensitive valve apparatus is operated by engine temperature and is interposed in a communicating passage between the inlet pipe and the negative pressure operated apparatus. The valve apparatus is so constructed that the negative pressure operated apparatus is brought into its operating condition by being in communication with the inlet pipe when the engine temperature is low, but is brought into inoperative condition by being in communication with the ambient air when the engine is heated to a predetermined temperature.

    摘要： A fuel supply system for an internal combustion engine utilizing an automatic transmission including a torque converter and a gear train has a carburetor with an inlet passage and a throttle valve therein. A sensing member is in a first position when the gear train is in a neutral position and a second position when the gear train is in a drive position. A throttle valve control slightly opens or closes the throttle valve in response to the sensing member. The throttle valve control operates to slightly open the throttle valve to hold the idling speed of the engine to a predetermined value when the gear train is in the drive position, thereby preventing the engine speed from decreasing due to the load.

    摘要： An engine idle speed governor arranged in a preferred embodiment to be operated by hydraulic pressure developed by restricting the power steering pump return flow line. A hydraulic diaphragm actuator motor operates the throttle and incorporates a dashpot to provide a throttle return check operative after manual actuation of the throttle. A control unit in the power steering pump circuit incorporates the restrictive orifice as well as various valves and mechanisms to provide governor damping, limit throttle opening travel upon oil flow failure and hold a fast idle position during cold starting and warm-up.

    摘要： An integrated anti-stall and idle-speed adjustment mechanism for an internal combustion engine including a dashpot means for arresting or time delaying the final closing movement of an engine throttle valve to prevent stalling of the internal combustion engine. This dashpot includes adjustment means for setting the stroke of the dashpot and for stopping the closing movement of the throttle valve to thereby set the idle speed position of the throttle and the internal combustion engine.

    摘要： The carburetor has a fuel/air mixture supply circuit constituted by the sequence of an ascending channel connected to a float chamber through an immersed calibrated orifice and a descending channel with an opening into the intake pipe of the carburetor downstream of the main throttle member of this pipe. The descending channel is controlled by a member which opens it only during periods of deceleration of the engine. The linking zone between the two channels is above the constant level of the float chamber and connected through an air passage having a second calibrated orifice, to an air intake zone of the carburetor other than that connected to the upper portion of the float chamber. The ascending channel has a further calibrated orifice above the constant level and communicates with the space above the constant level through a passage of small cross-section opening into the ascending channel between its two calibrated orifices and also itself above the constant level. The assembly reduces the suction in the ascending channel to an extent insufficient or sufficient to stop the fuel being sucked into the descending channel according as the closure member is open or not.
