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.

摘要: A controller for an engine including a fuel vapor processing mechanism. The controller determines the amount of fuel vapor drawn into an intake passage based on the concentration of fuel vapor purged into the purge passage. The controller corrects the fuel injection amount of a fuel injection valve in accordance with the determined amount of fuel vapor. The controller starts correcting the fuel injection amount from the cylinder that is undergoing an intake stroke when the crankshaft is rotated to a certain crank angle.

摘要: A shut off valve is provided in an intake line farther upstream than a throttle valve of the intake passage and farther downstream than an air cleaner. This shut off valve is opened by a signal or the like from an ECU when an engine is operating. Further, the shut off valve closes when the engine is stopped so as to suppress evaporative fuel inside the intake passage from flowing outside through the air cleaner. The evaporative fuel trapped inside the intake passage passes through a bypass passage that provides communication between the intake passage and the canister, and is then adsorbed with an adsorbent in the canister. A blow-by passage is also connected to the intake passage that is closed off by the shut off valve. Because the blow-by passage is closed off by a blow-by valve, which is closed during normal operation when the engine is stopped, sticking of the shut off valve and the throttle valve and the like due to the inflow of blow-by gas into the intake passage is inhibited.
摘要翻译: 在比进气通道的节流阀更上游的进气管线处设置截止阀,并且比空气滤清器更下游。 当发动机运行时,该关闭阀由来自ECU的信号等打开。 此外,当发动机停止时,截止阀关闭,以便抑制进气通道内部的蒸发燃料流过空气净化器。 捕集在进气通道内部的蒸发燃料通过旁通通道,该通道提供进气通道和罐之间的连通,然后吸附在罐中。 吹气通道还连接到由截止阀关闭的进气通道。 因为窜缸通过在发动机停止时的正常运转时关闭的窜气阀闭合,所以由于窜气的流入而使截止阀和节流阀等粘附 进入通道被禁止。

摘要: In a double-acting diaphragm pump, a diaphragm is provided to divide a pump body into two pump chambers. An electromagnetic-type reciprocating actuator is provided in a housing hermetically integrated with the pump body. Different from an electric-type pump, the actuator is integrally mounted on the double-acting diaphragm pump and an entire system is hermetically sealed. Therefore, even if the diaphragm is torn, fuel vapor is prevented from leaking outside. Additionally, four check valves are provided to control the discharge of vapor from a canister side to an engine side. These check valves may employ a reed to control vapor flow or a spring and plate to control flow. In addition, since the pump may be a double-acting type, a large discharge volume is obtained and the pump can be made smaller. The pump may also be a non double-acting type.

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: A fuel vapor leakage inspection apparatus utilizes a fuel tank, an adsorption container which houses an adsorbent for adsorbing fuel vapor generated in the fuel tank, and an exhaust device for communicating between the adsorption container and an intake pipe. Furthermore, the apparatus utilizes a pressure means that pressurizes or depressurizes a fuel vapor path formed from the fuel tank through the adsorption container to the exhaust device. A leakage detection means detects leakage from the fuel vapor path after the fuel vapor path is pressurized or depressurized by the pressure means while a calculation means calculates an amount of fuel vapor adsorbed, and a control means determines if the pressure means should execute leakage inspection of the fuel vapor path in accordance with the amount of the fuel vapor calculated by the calculation means.

摘要: An evaporated fuel adsorbing apparatus for an engine intake passage includes a layer of activated carbon disposed in the engine intake passage for adsorbing evaporated fuel. The activated carbon includes activated carbon pellets having pores. At least one of an average pellet size and an average pore size of the activated carbon is varied in an intake gas flow direction of the engine intake passage. More particularly, an average pore size of a first portion of the activated carbon located in an atmosphere side portion of the layer is greater than an average pore size of a second portion of the activated carbon located in an engine side of the layer. An average pellet size of the first portion of the activated carbon is smaller than an average pellet size of the second portion of the activated carbon.

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.
