摘要： An evaporative emission control apparatus for a motor vehicle includes a fuel tank having a tank shell to store fuel therein, a canister disposed completely within the fuel tank to adsorb and temporarily store evaporative fuel generated in the fuel tank, and a bracket that is secured to the fuel tank to support the canister apart from the tank shell. The outer surface of the canister is set apart from the inner surface of the tank shell, so that the canister is less influenced by the environment temperature around the fuel tank, and so that the adsorption of the evaporative fuel is kept stable.

摘要： A zero emissions fuel system includes a fuel tank fluidly interconnected with a fuel vapor containment and absorption canister. The canister is further interconnected with an engine intake manifold via a purge solenoid valve that controls the extent to which a vacuum in the intake manifold affects the canister. The canister is also interconnected with the ambient environment via at least one selectively operable valve. During normal operation of the engine, the purge solenoid valve allows the intake manifold to draw fuel vapor from the canister for consumption by the engine. At a predetermined vacuum pressure, the at least one valve opens, thereby allowing outside air to flow into the system through the vacuum relief valve to facilitate purging of the canister.

摘要： A vapor passage 20 that makes communication between a fuel tank 10 and a canister 26 is provided. A purge passage 34 that makes communication between the canister 26 and an intake passage 38 of an internal combustion engine is provided. A sealing valve 28 that controls a communication state of the vapor passage 20 and a purge VSV 36 that controls a communication state of the purge passage 34 are provided. A tank internal pressure sensor 12 detects tank internal pressure Pt. The purge VSV 36 is controlled to purge evaporated fuel into the intake passage 38 during operation of the internal combustion engine. The sealing valve 28 is opened/closed depending on whether a predetermined purge is performed in an area where the tank internal pressure Pt is positive.

摘要： When purge control of fuel vapor, which is released from a fuel tank and is then adsorbed and retained in a fuel adsorption layer of a canister, is performed through ON/OFF control of a purge valve, ON/OFF of a heater plate received in the canister is controlled based on a purge fuel vapor concentration estimated through air-fuel ratio control operation of an engine. In this way, a sensor for measuring the purge fuel vapor concentration of the fuel vapor conducted from the canister to an intake passage of the engine can be eliminated.

摘要： A shut valve is provided in an intake line farther upstream than a throttle valve of the intake line and farther downstream than an air cleaner. This shut valve is opened by a signal or the like from an ECU when an engine is operating. Further, the shut valve closes when the engine is stopped so as to suppress evaporative fuel inside the intake line from flowing outside through the air cleaner. The evaporative fuel trapped inside the intake line passes through a bypass passage that provides communication between the intake line and the canister, and is then adsorbed with an adsorbent in the canister. A blow-by line is also connected to the intake line that is closed off by the shut valve. Because the blow-by line is closed off by a blow-by valve, which is closed during normal operation, when the engine is stopped, sticking of the shut valve and the throttle valve and the like due to the inflow of blow-by gas into the intake line is inhibited.

摘要： A fuel feed pipe 1 having a branch pipe 6 for releasing evaporated fuel to a canister is provided, wherein the fuel feed pipe 1 is provided with a branch pipe blocking mechanism 8 for blocking an opening of the branch pipe 6 by being mechanically linked with the motion of inserting a fuel feed gun G. The branch pipe blocking mechanism 8 consists of a leaf spring 9 made of stainless steel and a rubber seal 10. A base end section of the leaf spring 9 is secured to a fuel feed guide 3 and a top side of the leaf spring 9 is provided with the rubber seal 10. When a shutter valve 4 is rotated by the insertion of the fuel feed gun G, the leaf spring 9 is elastically deformed by being mechanically linked with the rotation of the shutter valve 4 to allow the rubber seal 10 to close the opening of the branch pipe 6.
