摘要： A balance vent for an internally vented float fuel bowl type carburetor in order to dampen pulse signal fluctuation to the internal vent that is created upon an excess vacuum buildup in the float bowl. The balance vent is a restricted passageway that communicates at one end with the internal vent circuitry and at its opposite end with the atmosphere external of the carburetor. The balance vent is sized so that the vacuum in the fuel bowl is bled off to the atmosphere only to a certain extent to permit an overall bowl vacuum to remain so that the characteristics of the internal bowl vent are maintained.

摘要： A fuel supply system for a two cycle crankcase compression internal combustion engine embodying direct cylinder injection and carburetors for supplying a fuel air mixture to the crankcase chambers of the engine for high speed cooling. The direct fuel injectors supply the fuel at the low speed operation and a fixed amount of fuel at mid range and high speed, while the carburetor supplies only the mid range and high speed requirements of the engine in combination with the fuel injectors. Fuel is supplied first to the fuel bowls of the carburetors which have a vapor vent and then from the fuel bowls to the fuel injectors so as to avoid the necessity of a separate vapor separator for the fuel injectors.

摘要： A carburetor for an internal combustion engine is provided. The carburetor float bowl is internally vented through a venting path that leads from the carburetor throat, via the primer chamber, to the airspace above the float bowl. An annular lip is provided on the primer bulb that acts as a check valve and seals off the venting passageway when the primer bulb is depressed, thereby insuring that the primer charge passes into the float bowl and is not lost through the venting passageway.

摘要： 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.

摘要： A fuel vapor control device having a valve opening and closing a passage connecting a carburetor and a charcoal canister according to a predetermined temperature. A first coil spring formed by a "shape memory effect" alloy is provided to urge the valve to open the passage when the temperature is high. A second coil spring urges the valve to close the passage. A solenoid is provided to urge an armature against the valve to close the passage against the force of the first coil spring when the engine is running. The solenoid heats the first coil spring to generate a spring force therein when the engine is running. When the engine is turned off, the solenoid is deactivated, and the force of the first spring overcomes the force of the second spring to open the passage until such time as the temperature of the first spring drops below the predetermined temperature.
