摘要: A vapor storage canister incorporates a liquid trap that protects the carbon bed, but which avoids purging liquid directly out of the trap. The trap consists of a cup that forms an interior cavity at the bottom of, and surrounded by, the carbon bed. The purge tube does not enter the trap directly, but instead runs to a plenum that draws from the bottom face of the carbon bed. The trap, in turn, is open to the interior of the carbon bed only through a screen mesh grid. Consequently, vapor can be pulled from the trap at purge, but not liquid.

摘要: A canister adapted to store fuel vapor discharged from a fuel tank has an inlet chamber that forms a trap for liquid fuel. Fuel is purged from the canister through a purge tube that has a small liquid purge hole at the bottom of the chamber and a large vapor purge hole spaced above the bottom of the chamber.

摘要: A purge control device for an evaporative control system comprises a single housing having two solenoid actuated valves controlling parallel orifices leading from an inlet chamber to an exit flow path. The two solenoid valves have different sized orifices to provide different flow capacities. Purge flow is controlled by an electronic control module which regulates the duty cycle of the solenoids. Each valve receives its own signal so that the flow through the orifices is individually controlled.

摘要: A variable purge orifice assembly for an evaporative emission system of a vehicle includes a housing for fluid connection to a vapor canister and a purge solenoid of the evaporative emission system. The housing has a purge orifice therein. The variable purge orifice assembly also includes a regulating device connected to the housing and for connection to an engine of the vehicle. The regulating device is actuated by manifold vacuum from the engine to vary flow of fuel vapor through the purge orifice from the vapor canister to the purge solenoid.

摘要: In a system for delivering air from an air pump to an exhaust system and accessories for an internal combustion engine, an air flow control unit has a high pressure relief valve, an outlet open to the exhaust system, a vent open to the atmosphere and an outlet open to the accessories with a check valve therein. A valve member is movable in response to an engine signal between a first position closing the exhaust system outlet and a second position closing the vent; and a low pressure relief valve is included in the vent to maintain a minimum low pressure in the unit when the valve member is in its first position.

摘要: In a system for delivering air from an air pump to the exhaust system of an internal combustion engine, an air diverter valve assembly has a regulating control responsive to air pump discharge pressure which positions the diverter valve member to divert excess air flow away from the exhaust system when the pressure exceeds a selected value. The assembly also has a timed anti-backfire provision effective to override the regulating control and divert all air flow to the atmosphere upon a sudden decrease in induction manifold pressure.
