Abstract: An engine with a supercharger includes a low pressure loop EGR apparatus. An EGR passage having an inlet connected to an exhaust passage downstream of a turbine and an outlet connected to an intake passage upstream of a compressor. An intake bypass passage is provided to bypass the intake passage downstream of the compressor and the intake passage upstream of the compressor, with an ABV in the intake bypass passage. A throttle valve is closed during stop or deceleration operation of the engine. An electronic control unit (ECU) is configured such that, when the ECU determines based on an operation state of the engine that the EGR valve is in a valve-opened state and the engine is in deceleration operation from a supercharging region, the ECU controls an EGR valve to close and the ABV to open from a valve-closed state delayed from start of closing the EGR valve.

Abstract: An engine includes a EGR valve to regulate a EGR flow rate. A blow-by gas recirculation passage allows blow-by gas generated in the engine to flow in a surge tank to return to the engine. A PCV valve operates in response to negative pressure to regulate a blow-by gas flow rate in the recirculation passage. During deceleration fuel cutoff of the engine, an ECU holds a throttle valve at a predetermined slight opening degree and controls the EGR valve to be forcibly opened from a valve-closed state to change intake pressure (negative pressure) in the surge tank and determines whether or not the PCV valve is in sticking failure based on changes in intake amount detected by an air flow meter before and after the negative pressure changes.
Abstract translation: 发动机包括调节EGR流量的EGR阀。 窜气再循环通道允许在发动机中产生的窜气在缓冲罐中流动以返回发动机。 PCV阀响应于负压操作以调节再循环通道中的窜气流量。 在发动机的减速燃料切断期间，ECU将节气门保持在预定的微小开度，并且控制EGR阀从阀关闭状态被强制打开以改变缓冲罐中的进气压力（负压），并确定是否 或者不是基于空气流量计在负压变化之前和之后检测到的进气量的变化而导致PCV阀处于粘附故障。

Abstract: An EGR apparatus for an engine includes an EGR passage, an EGR valve, an accelerator sensor, and an ECU. The ECU compares a change amount (accelerator operating speed) per unit of time of an accelerator opening degree to a predetermined first determination value. When it is determined that a request for deceleration operation or acceleration operation is made to an engine, the ECU issues a fully closing command to the EGR valve. When it is determined that the deceleration or acceleration operation request is continued, the ECU continues to issue the fully closing command. When the deceleration or acceleration operation request is removed and the accelerator opening degree is larger or smaller than a predetermined second determination value, the ECU releases the fully closing command.

Abstract: A supporting structure includes a housing accommodating an all-solid-state battery; and a supporting member interposed between the all-solid-state battery and the housing and supporting the all-solid-state battery while the all-solid-state battery is accommodated in the housing. The supporting member includes a plurality of first spring portions arranged in a first direction orthogonal to a direction in which the all-solid-state battery and the supporting member are arranged. The first spring portions each include a first supporting point portion projecting toward the housing or the all-solid-state battery; a pair of second supporting point portions projecting toward an opposite side to the first supporting point portion at positions spaced from the first supporting point portion in the first direction; and a first cavity portion provided between the pair of second supporting point portions at a position facing the first supporting point portion.

Abstract: An EGR gas distributor includes a gas chamber, a gas inflow passage to introduce EGR gas on its upstream side, gas outflow passages to discharge the EGR gas to branch pipes on their downstream side. An inner wall on a downstream side of the gas chamber is divided into downstream-side divided walls corresponding to the respective gas outflow passages, and the downstream-side divided walls are curved or slanted to be of protrusion-like shape protruding toward the corresponding gas outflow passages. Downstream-side dividing ridges are provided each between the adjacent downstream-side divided walls. An inner wall on the upstream side of the gas chamber is placed to face the downstream-side inner wall and provided with at least one upstream-side ridge protruding toward the downstream-side divided walls in each area corresponding to the downstream-side divided walls.

Abstract: A double eccentric valve: a valve seat; a rotary shaft; a valve gear with a rotary shaft base end portion; a motor rotating the shaft via a valve gear; bearings supporting the shaft in a cantilever manner; a return spring giving, to the valve gear, spring force for rotating the shaft in a valve body closing direction; and a full-close stopper to restrict valve gear rotation with the shaft when the valve body is fully closed. When the motor is not driven, the valve gear partially contacts the full-close stopper by spring force, moment acting on the valve gear is caused to act on the rotary shaft with the contact point serving as a fulcrum, the rotary shaft is tilted toward the valve seat with the contact point between the rotary shaft and the bearing serving as a fulcrum, and thus, the valve body is pressed against the valve seat.

Abstract: The engine system includes: an engine equipped with a supercharger; an electronic throttle device; a low-pressure loop EGR device including an EGR valve; a fresh air introduction device; and an electronic control unit (ECU). The fresh air introduction device includes a fresh air introduction passage and a fresh air introduction valve for introducing fresh air to an intake passage disposed downstream of the electronic throttle device. The electronic throttle device is configured with a DC motor type, and the fresh air introduction valve is configured with a step motor type. Upon determining that the engine is decelerating, the ECU causes the EGR valve to close fully and the fresh air introduction valve to open to a predetermined degree, while also controlling the electronic throttle device to close to a predetermined opening degree, thereby adjusting the total intake amount to the engine.

Abstract: An engine system includes an injector, an EGR device (including an EGR valve having a step motor) to recirculate part of exhaust gas of an engine as EGR gas to the engine, and an electronic control unit (ECU) to control the injector, the EGR valve, and others based on an operating state of the engine. The ECU is configured to diagnose foreign-matter lodging abnormality of the EGR valve and a lodged foreign-matter diameter based on detected intake pressure during engine deceleration. When existence of the abnormality and the foreign-matter diameter are determined, the ECU controls the step motor to hold the EGR valve at a first opening degree smaller than a second opening degree needed to remove a foreign matter before fuel cut to the engine by the injector.

Abstract: An eccentric valve has a drive mechanism, a drive force receiving part, a bearing for supporting a rotary shaft, and a return spring for generating a return spring force. During non-operation of the drive mechanism, the eccentric valve generates a separating-direction urging force to cause the rotary shaft to incline about the bearing serving as a fulcrum and urge the valve element in a direction away from the valve seal, the separating-direction urging force being a force caused by the return spring force. Either the valve element or the valve seat is provided with a sealing member to seal between the valve element and the valve seat during non-operation of the drive mechanism.

Abstract: A valve housing that has a flow passage. Arranged in the flow passage are a valve seat that includes a valve hole, valve body that can be seated on the valve seat, and a section of a rotary shaft with the valve body fixed to the tip thereof. A ring-shaped seat surface is formed in the valve hole of the valve seat. A ring-shaped sealing surface corresponding to the seat surface is formed on the perimeter of the disc-shaped valve body. By rotating the rotary shaft, the valve body rotates open from a closed state in which the valve body is seated on the valve seat and the sealing surface is in contact with the seat surface. A tapered upstream-side flow regulating part is provided in the valve hole of the valve seat, so as to widen from the seat surface toward the upstream side of the EGR gas flow.
