摘要： A fuel adsorption layer formed in a canister is partitioned into an upper adsorption layer and a lower adsorption layer by a partition plate in which a heater is embedded. The relation between a heating value of the heater and thickness X of the upper and lower adsorption layers is set so that the temperature of a part closest to the heater heating face of the fuel adsorption layer is lower than a fire point of the fuel, and the temperature of a part farthest from the heater heating face is higher than the boiling point of the fuel. With the configuration, by heating the fuel adsorption layer by the heater, the desorption performance of activated carbon is improved, and almost all of the fuel vapors adsorbed can be desorbed.

摘要： An evaporated fuel adsorbed by an adsorbing member of a canister is compulsively desorbed by driving of a purge pump and is introduced into an intake passage of an internal combustion engine. In this instance, intake pulsation of the intake passage of an internal combustion engine is introduced into a driving chamber of the purge pump and a partition is moved, so that the capacity of a pump chamber is varied. In other words, the purge pump conducts its pump operation by utilizing the movement of the partition resulting from the introduction of intake pulsation of the intake passage of the internal combustion engine, and a power loss can be thus reduced. When a pressure difference is small between the intake pressure inside the intake passage of the internal combustion engine and the pressure on the canister side, too, a desired purge flow rate can be secured in accordance with the operating condition of the internal combustion engine.

摘要： An absorbent, such as, for example, an active carbon, is provided in an intake air passage, for example, in an air cleaner, to efficiently adsorb fuel vapor. To ensure that fuel vapor adsorbed into the intake air passage can be efficiently desorbed even when there is only a small amount of the intake air, an intake throttle valve is provided upstream of the adsorbent and an opening of the intake throttle valve is throttled so as to decompress an area near the adsorbent. Desorption of fuel vapor also can be efficiently promoted by using a heater to directly heat the adsorbent in the intake air passage or by heating the intake air to indirectly heat the adsorbent.

摘要： An apparatus detects leak in a fuel vapor treatment system which is referred to as an evaporation system. The apparatus measures a required time T2 that is required for decreasing pressure in the evaporation system from P0 to P1 while opening a base leak hole that provides known amount of leak. Then, a required time T1 that is required for decreasing pressure from P0 to P1 is measured while closing the base leak hole. The apparatus compares the required times T1 and T2 in order to detect a leak other than the base leak hole. In this process, a specified coefficient that is defined in accordance with the base leak hole is taken into consideration. It is possible to detect the leak of the evaporation system with high accuracy even when the amount of remaining fuel is extremely large.

摘要： A PCV valve is arranged in an outflow passage. An ECU controls rotation of a motor such that an opening degree of the PCV valve increases in response to an increase in an opening degree of a throttle valve. The outflow passage connects an interior of a head cover of an engine to a portion of an intake air passage located on a downstream side of the throttle valve. The outflow passage recirculates blow-by gas leaked from a combustion chamber into an interior of a crankcase to the portion of the intake air passage located on the downstream side of the throttle valve. An inflow passage connects the interior of the head cover to a portion of the intake air passage located on an upstream side of the throttle valve. The inflow passage conducts intake air from the intake air passage to the interior of the head cover.
