摘要:
A sheet-like adsorption filter formed by sandwiching particulate activated carbon with heat-resistant nets and non-woven fabric sheets that have a percentage of void of 90% or higher, is disposed at an internal combustion engine side of a filter element.
摘要:
A limiting portion of a support member, which rotatably supports an accelerator pedal, forms a gap between a contacting portion of the accelerator pedal and the limiting portion in a state where the accelerator pedal is rotated in a depressing direction. A cover member is provided to one of the support member and the accelerator pedal and covers the gap at any rotational position of the accelerator pedal within a rotatable range of the accelerator pedal.

A rotation angle detecting unit includes a pedal arm rotated by the pedal force transmitted from an accelerator pedal, an urging device urging the pedal arm in an opposite direction from a direction, in which pedal force is applied to the pedal arm, a pedal rotor engaging the pedal arm to transmit urging force of the urging device to the pedal arm, and a rotation angle detecting device detecting the rotation angle of the accelerator pedal. The rotation angle detecting device includes a movable part attached to the pedal rotor and thereby displaced together with the pedal rotor, and a stator that outputs an electric signal, which is associated with a rotational position of the pedal rotor due to one of magnetic and electric interactions with the movable part.

A spring damper for absorbing vibration of a double coil spring is made of elastic material and composed of a cylindrical body, outer-wall convex portions, and inner-wall convex portions. The spring damper is arranged in an annular space formed between an outer coil spring and an inner coil spring of the double coil spring, so that the outer-wall convex portions push the outer coil spring in a radial outward direction and the inner-wall convex portions push the inner coil spring in a radial inward direction. Longitudinal ends of the cylindrical body are prevented from being hooked by spring wires of the outer or inner coil spring, when the double coil spring is expanded and compressed.
摘要:
An accelerator pedal rotates a pedal rotor when depressed. Rotors located on both sides of the pedal rotor are relatively rotatable to the pedal rotor. Second helical teeth of the rotors project toward the pedal rotor and engage with first helical teeth of the pedal rotor to bias the rotors when the pedal rotor rotates in the accelerator opening direction. The pedal rotor is rotatable to an accelerator full-close position without interfering with the first helical teeth when the pedal rotor rotates in an accelerator closing direction. A first biasing unit biases the rotors in the accelerator closing direction. A second biasing unit biases the accelerator pedal or the pedal rotor in the accelerator closing direction.

摘要:
A throttle valve is opened after stopping an engine to prevent the valve from sticking. Then, when a temperature of the valve has become lower than the polymerization temperature, the valve is closed to seal the vapor of the HCs in a surge tank downstream. Changes in the temperature of the valve are, for example, estimated based on a temperature of an intake air detected by an intake temperature sensor.
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:
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.
