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： The amount of flow in a canister is controlled, in a fuel-vapor emission-control system, in response to the operating condition of an engine, control being performed of the size of a release port on the canister responsive to the amount of purge, thereby enabling a large purging amount. An electromagnetic valve capable of changing the surface area of the port is provided at the atmospheric side of a port of the canister. The degree of opening of this electromagnetic valve is varied, depending on the conditions of refueling, traveling, and parking, and during a purge, the opening of the electromagnetic valve when the amount of purge is large is made larger then when the amount of purge is small. By doing this, the recovery of hydrocarbons from the canister when purging is done is speed up, thus improving the working capacity of the canister.

摘要： An exhaust purifying apparatus for an internal combustion engine includes an exhaust purifying mechanism, a fuel adding device, an electronic control device. The exhaust purifying mechanism is located in an exhaust passage and traps particulate matter. The fuel adding device adds fuel to exhaust gas that passes through the mechanism. The electronic control device detects a pressure difference between a section upstream and a section downstream of the exhaust purifying mechanism. While the fuel adding device is adding fuel to exhaust gas, the electronic control device compares the pressure difference that is detected at a predetermined point in time with the pressure difference reference value. When the pressure difference exceeds the pressure difference reference value, the electronic control device sets the manner of adding fuel to intermittent fuel addition. As a result, the exhaust purifying apparatus decreases the amount of particulate matter that remains in the exhaust purifying mechanism.

摘要： An exhaust purifying apparatus for an internal combustion engine includes execution means, wherein, when an accumulation amount of particulate matter about a catalyst becomes less than a first determination value after a PM elimination control is started, the execution means executes burn-up control. Stopping means stops the PM elimination control based on an end of the burn-up control. Forcibly ending means forcibly ends the burn-up control when time elapsed since the accumulation amount of particulate matter about the catalyst has dropped to a second determination value reaches a predetermined time. Therefore, the exhaust purifying apparatus is capable of completely burning particulate matter in a PM filter, and suppresses degradation of fuel economy.

摘要： A three-way catalyst device having an oxygen absorbing/releasing capability is provided in an exhaust passage of an internal combustion engine. An upstream-side air-fuel ratio sensor that outputs an output value in accordance with the air-fuel ratio of exhaust gas is provided in the exhaust passage upstream of the three-way catalyst device. A downstream-side air-fuel ratio sensor that outputs an output value in accordance with the air-fuel ratio of exhaust gas is provided in the exhaust passage downstream of the three-way catalyst device. A comparison value is calculated by comparing the length of an output locus formed by output values of the upstream-side air-fuel ratio sensor and the length of an output locus formed by output values of the downstream-side air-fuel ratio sensor. By comparing the comparison value with a predetermined criterion, it is determined whether the three-way catalyst device has deteriorated. At least one of the downstream-side air-fuel ratio sensor output value and the predetermined criterion is corrected in accordance with the downstream-side air-fuel ratio sensor output value. Therefore, deterioration of the three-way catalyst device can be determined with high precision.
