    摘要: An exhaust gas control apparatus for an internal combustion engine includes an exhaust gas purification catalyst device provided in an exhaust passage for the engine; an HC adsorption portion, provided in the exhaust passage, which adsorbs hydrocarbon in exhaust gas; a passage switching portion that selectively closes/opens a second passage bypassing the HC adsorption portion using an intake pipe negative pressure in the engine so that the exhaust gas flows in a first passage provided with the HC adsorption portion, or in the first passage and the second passage; and a control portion that controls the negative pressure so that the second passage is closed, when a predetermined condition is satisfied at the time of start of the engine. The control portion executes at least one of a control that advances the valve timing of an intake valve, and a control that reduces the opening amount of a throttle valve.

    摘要: In an exhaust passage, a pressure detection means is provided on the upstream side of a filter, and an exhaust throttle valve is provided on the downstream side of the filter. And, when the operational state of the internal combustion engine is a steady operational state (in a step S101), the opening amount of an exhaust throttle valve is controlled so that the upstream pressure detected by the pressure detection means becomes a constant value (in a step S103).

    摘要: An exhaust gas throttle valve disposed in the exhaust system of an engine, wherein the center axis of rotation of a valve shaft 5 is set at a position deviated from the center axis of the exhaust gas passage, and two recessed portions 11 are symmetrically formed in the circumferential portion of a valve body 4 by cutting the surface thereof. The positions where the recessed portions 11 are formed are on the side of the center axis of the exhaust gas passage beyond the center axis 12 of rotation, and at where the peripheral portion of the valve body 4 faces the edge portions 9 where insertion holes 8 for the valve shaft 5 are opened in the exhaust gas passage. At these positions, the distance is a minimum between the peripheral portion of the valve body 4 and the edge portions 9. The recessed portions 11 work to increase the gap relative to the edge portions 9 at that positions. It is therefore made possible to approximate the peripheral portion of the valve body 4 to the tubular wall of the exhaust gas passage 2 when the exhaust gas throttle valve is closed preventing the valve body 4 and the edge portions 9 from coming in contact together despite of the thermal expansion.
