摘要： Disclosed is an exhaust gas recirculation apparatus for an internal combustion engine, which has a vacuum operated flow control valve arranged on pipe means connecting the exhaust manifold of the engine with the intake manifold of the engine. When the throttle valve is opened from its idle position during the operation of the engine, the flow control valve is opened in order to recirculate exhaust gas from the exhaust manifold to the intake manifold. The apparatus further has means for opening the flow control valve when so-called "dieseling" takes place after the operation of the engine is stopped. The exhaust gas due to the dieseling can be recirculated and, thus, the dieseling is instantly stopped.

In the housing, a fuel adsorption filter is arranged downstream of the air filter in such manner as to intersect an air passage. An open portion and a sheet-like adsorption portion are vertically defined in an outer frame of the fuel adsorption filter. The adsorption portion has a fuel adsorbing function. A weir is provided in a boundary between the open portion and the adsorption portion. The weir limits air flow from the upstream side of the adsorption portion to the upstream side of the open portion. A flow straightening plate having a flow straightening function is provided in the open portion.

摘要： An intake system (10, 20) for a vehicle internal combustion engine is provided in which a first air intake duct (16), having an air intake inlet (16a) to inhale external air, is connected to an air cleaner box (14). A second air intake duct (17, 27) is also connected to the air cleaner box. The air intake inlet is closer to the air cleaner box than the second air intake duct is. The cross section area of a second air intake duct is greater than the cross section area of the first air intake duct. The center axis of the second air intake duct at an end on the side of a second air intake opening (12, 22) intersects with the center axis of the first air intake duct at an end on the side of a first air intake opening (11).

摘要： An evaporated fuel adsorbing mechanism for an internal combustion engine includes an adsorbing member provided in an intake passage of the internal combustion engine to adsorb evaporated fuel that flows back through the intake passage when the engine is stopped. The adsorbing member includes a connecting portion connected to an inner peripheral surface of the intake passage, an end portion that is away from the inner peripheral surface, and that is disposed downstream of the connecting portion in an intake-air flow direction in which intake air flows, and an upstream-side surface that faces toward an upstream side in the intake-air flow direction, and a downstream-side surface that faces toward a downstream side in the intake-air flow direction. The upstream-side surface and the downstream-side surface extend from the connecting portion to the end portion.
