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.

摘要： A fuel vapor handling apparatus supplies a purging air to a canister by using a purge pump and purges fuel desorbed from the canister into an intake pipe. A controller intermittently operates the purge so that the canister internal temperature recovers from a reduced level caused by the latent heat of vaporization of fuel during an operating period of the purge pump. Therefore, desorption of fuel from the canister during an operating period is facilitated. Since the actual operating time of the purge pump is reduced, the life of a motor that is a power unit of the purge pump becomes longer.
