An internal-combustion-engine supercharger includes a centrifugal compressor, a pre-compression flow path, a post-compression flow path, a bypass passage, and a control valve. The centrifugal compressor is disposed in an intake passage of an internal combustion engine and has an impeller to compress and discharge intake air using a radial centrifugal force generated by rotating the impeller. The intake air in the post-compression flow path is to be recirculated to the pre-compression flow path via the bypass passage. A connecting portion between the bypass passage and the pre-compression flow path is disposed at a position other than an extreme-bottom surface portion located at a lowest portion in a flow path section of the pre-compression flow path in a state where the internal-combustion-engine supercharger is installed in a vehicle. The control valve is disposed in the bypass passage to control a recirculation flow rate of the intake air.

A vehicular suction noise transmission system includes a first intake apparatus, a second intake apparatus, a fuel recirculation apparatus, and a suction noise transmission apparatus. The first intake apparatus is connected to an internal combustion engine mounted in a vehicular engine compartment. The second intake apparatus is connected to the internal combustion engine. The suction noise transmission apparatus includes a first suction noise transmission end, a second suction noise transmission end, and a vibrating body. The first suction noise transmission end is connected to the second intake apparatus. The second suction noise transmission end is in communication with a vehicle interior. The vibrating body is provided to separate a second intake apparatus side and a vehicle interior side and configured to vibrate according to an intake pulsation so as to transmit a suction noise of the internal combustion engine to the vehicle interior.

An internal combustion engine exhaust system supporting structure includes a body fastening portion, an exhaust fastening portion, a bracket, and a stay. The body fastening portion is provided on a power plant or a vehicle body located on a side of an exhaust passage extending from an internal combustion engine to a rear of a vehicle so that exhaust emissions flow from the internal combustion engine to the rear of the vehicle. The bracket is fastened to the body fastening portion. The stay is fastened to the exhaust fastening portion and has lower stiffness than the bracket. The bracket and the stay are fastened to each other at a connecting portion so that a vertical distance between the exhaust fastening portion and the connecting portion in a vertical direction is greater than a vertical distance between the body fastening portion and the connecting portion in the vertical direction.

A gasket is provided that can effectively alleviate stresses arising therein when at high temperatures. A substantially annular gasketused in coupling an outletof a turbocharger; the gasketincludes a gasket facethat is an abutting face of the gasketthat abuts a flangewhen the gasket is in a state fitted to the flangeof an outlet; and the gasket faceis an annular shape having the plurality of fastener holesA,A,A andA, and in an area between one fastener hole and another fastener hole, the width of a portion H that reaches the highest temperature by exhaust gas channeled by the W/G valveimpinging thereon is formed to be the narrowest, and the width gradually increases as approaching towards the one fastener hole or the other fastener hole from the portion.

An exhaust apparatus for an internal combustion engine includes a first exhaust collecting section, a first exhaust passage, a first exhaust sensor, and a rib. The first exhaust passage is connected to the first exhaust collecting section and has a curved shape to change a flow direction of the exhaust gas from a direction in which the exhaust gas is ejected from each of first cylinders. The first exhaust passage includes an outer wall provided on a radially outer side of the curved shape. The rib is provided on the outer wall of the first exhaust passage and extends along a direction perpendicular to a direction in which the exhaust gas flows. The rib is positioned downstream from the first exhaust sensor.

The present invention employed an elevating device for a window glass provided in a door of a vehicle, including: a guiding device which is provided in the door; a career plate which engages with the guiding device and slidably moves in an elevating direction of the window glass in relation to the guiding device; and a driving device which raises and lowers the career plate. The career plate is provided with a stopper which abuts on the guiding device when the career plate reaches an elevation-limiting position. The stopper is provided with an attaching portion which is attached to the career plate, and an abutting portion which abuts on the guiding device and elastically deforms when the stopper reaches the elevation-limiting position. The abutting portion is formed such that a width thereof becomes wider than the attaching portion and such that the width becomes smaller toward a distal end side.

Elevating device for window glass

A recirculation exhaust gas extracted from the exhaust passage of an internal combustion engine and flowing through a recirculation passage. A recirculation control valve ( ) controls the flow of the recirculation exhaust gas in the recirculation passage. A recirculation pipe ( ) forming the recirculation passage has a hot or contact section ( ) extending near and along an exhaust manifold ( ). The recirculation pipe ( ) and the exhaust manifold ( ) are covered with a heat-insulation cover ( ). The drop of the temperature of the recirculation exhaust gas flowing through the recirculation passage is suppressed and the deposition of deposits including carbon in the recirculation control valve ( ) is suppressed.
