    摘要: A sealing valve 28 that controls a communication state between a fuel tank 10 and a canister 26 is provided. During stop of an internal combustion engine, the sealing valve 28 is generally closed, and the canister 26 is opened to the atmosphere. The sealing valve 28 is opened when the internal combustion engine is stopped, and differential pressure exceeding a valve opening determination value is generated between tank internal pressure and atmospheric pressure. A change in the tank internal pressure generated between before and after the sealing valve 28 is opened is detected. When the change in the tank internal pressure is below a predetermined determination value, closing failure of the sealing valve is determined.

    摘要: A fuel-vapor emission-control system for an internal combustion engine which is capable of achieving both a reduction of the exhaust of vapor into the atmosphere and the prevention of an excessive increase in pressure within the fuel tank, regardless of the amount of internal pressure in the fuel tank, by providing on an atmospheric release port of the canister which adsorbs vapor adsorbed from the fuel tank of the internal combustion engine, thereby preventing release of the vapor into the atmosphere, an atmospheric release surface area changing valve which changes the surface area of an aperture to the atmosphere. The atmospheric release surface area valve operates to make the atmospheric release surface area larger when the internal pressure in the fuel tank is large than when the internal pressure in the fuel tank is small. The atmospheric release surface area changing valve can be configured as a mechanical type of pressure-sensitive valve which opens when the internal pressure in the canister exceeds a set value, and can also be configured as an electromagnetic valve, the degree of opening of which can be electrically varied in response to a detected value of vapor pressure within the system to thereby change the atmospheric release surface area.

    摘要: An apparatus for preventing discharge of fuel vapor has a differential pressure valve. Before a fuel tank opens to the atmosphere due to removal of a fuel cap, the apparatus leads fuel vapor in the lower pressure chamber of the differential pressure valve to a canister for processing therein and opens the differential pressure valve to lead fuel vapor in the fuel tank to the canister for processing therein. The fuel tank is connected to the canister via the differential pressure valve. The lower pressure chamber of the differential pressure valve is connected to the canister via a connection pipe, a communication valve, and a connection pipe. When a fuel lid is opened, the communication valve is opened to lead fuel vapor in the lower pressure chamber of the differential pressure valve to the canister. At this time, a pressure difference is produced between the lower pressure chamber and the high pressure chamber of the differential pressure valve, so that the differential pressure valve is opened to lead fuel vapor in the fuel tank to the canister for processing therein.

    摘要: An apparatus for controlling the evaporated fuel of an internal combustion engine secures the working capacities of the canisters and properly controls an air-fuel ratio when resuming the purging of evaporated fuel into the engine.The apparatus has the first and second canisters for adsorbing evaporated fuel produced in a fuel tank. The canisters are connected in series between an atmospheric hole of the first canister and an intake duct of the engine. Air from the atmospheric hole passes through the canisters and releases the fuel adsorbed by the canisters. The air and released fuel are purged into the intake duct. During the operation of the engine, a path guides evaporated fuel from the fuel tank into an adsorption material disposed in the second canister, so that the fuel adsorption state of the adsorption material is substantially unchanged between a given purge operation and the next purge operation around a path for purging air and fuel from the second canister into the intake duct. The apparatus also has a fuel supply controller that uses the concentration of purged fuel of a first purge operation when calculating, at a second purge operation, a fuel injection quantity to achieve a target air-fuel ratio.

    摘要: A fuel vapor emission control system for connection to an engine having a fuel tank, so as to purge fuel vapor introduced thereto into the engine, comprises primary and secondary adsorbing layers for temporarily adsorbing fuel vapor introduced thereto. The primary and the secondary layers are connected in series. The air is introduced into, in turn, the primary and the secondary layers so that the air passing therethrough desorbs fuel vapor therefrom, and then into the engine, together with fuel vapor desorbed from the primary and the secondary layers, when the engine is running. During an engine fuelling operation, fuel vapor is introduced from the fuel tank to the primary layer. When the engine is running, fuel vapor is introduced, from the fuel tank, into the engine by bypassing the primary and the secondary layers.
