    摘要: An intake manifold (2) for an internal combustion engine equipped with an exhaust gas recirculation (EGR) system for recirculating a part of the exhaust gas to the intake system, having a V-shaped rib (13) formed on the inner surface thereof with the vertex (13a) directed upstream with respect to the flow of the intake air. The V-shaped rib is positioned upstream of the EGR gas outlet (10) of the EGR system so that oil contained in blow-by gas supplied by a positive crankcase ventilation (PCV) system or charged-air supplied by a turbocharger into the intake manifold (2) does not flow into the EGR gas outlet (10), but flows away from the EGR gas outlet (10). Therefore, the deposition of sludge around the EGR gas outlet (10) is prevented and a sufficient EGR rate is secured.

    摘要: A semiconductor light emitting device comprises a metallic support plate 1; a light-reflective reflector 3 mounted on the support plate 1 and formed with a hole 3a; a semiconductor light emitting element 2 mounted on the support plate 1 within the hole 3a of the reflector 3, and a plastic encapsulant 6 for sealing an outer periphery of the reflector 3 and an upper surface 1c of the support plate 1. As the reflector 3 is electrically connected to a wiring conductor 5 or a lead wire 8 extends through a notch 3k formed in the reflector 3 to electrically connect the semiconductor light emitting element 2 and wiring conductor 5, wiring span of the lead wire 8 can be shortened to prevent deformation of the lead wire 8. Simultaneously, diameter of the reflective surface 3c in the reflector 3 is reduced and height of the reflector 3 is increased to improve directivity and axial brightness of light from the semiconductor light emitting device. Also, formation of the hole 3a effectively prevents further thermal degradation of heat-resistible plastic encapsulant 6 or other resin components.

    摘要: An intake manifold (2) for an internal combustion engine equipped with an exhaust gas recirculation (EGR) system capable of recirculation a part of the exhaust gas to the intake system, having a configuration capable of preventing oil contained in the blow-by gas supplied by a positive crankcase ventilation (PCV) system or the air supplied by a turbocharger from flowing into the EGR gas outlet (10) of the EGR system opened to the intake manifold (2). The EGR outlet (10) is formed in the upper section of the interior of the intake manifold (2) so that the flow of oil into the EGR gas outlet (10) is impeded.
