摘要： An internal combustion engine, wherein fuel vapor adsorbed in a canister (22) is purged into a surge tank (13) through a purge control valve (28). A target value of the fuel vapor rate showing the ratio of the amount of fuel vapor in the purge gas to the amount of fuel injection is stored in advance. At least one of the amount of purge gas or the amount of fuel injection is controlled so that the fuel vapor rate becomes the target value.

摘要： A diagnostic apparatus for a fuel vapor treating apparatus closes a breather to shut a purge system valve during purge. While further continuing the purge, the apparatus detects the purge flow thereby caused and a pressure change occurring in the purge system. Based on the purge flow and the pressure change, the space volume in the purge system is estimated. By comparing the estimated space volume and the actual space volume in the purge system, the apparatus determines whether there is a failure or fault in the purge system.

摘要： An evaporative fuel processing apparatus which can optimally process fuel gas according to navigation information or the like. This apparatus obtains future running information from a navigation system and further predicts an amount quantity of fuel vapor generated in a fuel tank (13) according to the running information. Further, the apparatus determines an amount of fuel vapor to be purged from a canister (14), namely, a valve opening of a purge control valve (142) so that an amount of fuel vapor adsorbed in the canister (14) is not more than a predetermined upper limit and that an amount of fuel adsorbed in the canister (14) after running is almost zero. Thus, an evaporation emission is reduced and the durability of the canister is prolonged by controlling the purge control valve.

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.
