摘要： A hydrocarbon trapping layer (25) is formed by coating a hydrocarbon trapping material onto a carrier (21A). A number of exhaust gas passages (34) are formed in the carrier (21A) and a plurality of slits (22) are formed on the carrier (21A) to cross the passages (24) in a transverse orientation. The slits (22) delay temperature increases in the downstream hydrocarbon trapping layer (25) and delay the release of trapped hydrocarbons therefrom. This is due to blocking the transmission of heat to the downstream hydrocarbon trapping layer (25) from the upstream hydrocarbon trapping layer (25). The slits (22) further produce a turbulent flow in the flow of exhaust gas and promote diffusion of exhaust gas over the entire surface of the carrier (21A).

摘要： A catalytic converter is interposed in an exhaust passage of an internal combustion engine. In the converter, a plurality of carriers are disposed in series with gaps. Each carrier comprises a hydrocarbon trapping layer, a three-way catalyst layer and a number of passages facing the three-way catalyst layer. The gaps interrupts heat transfer between the carriers in order to retard temperature increase in the hydrocarbon trapping layer and promotes a turbulence in exhaust gas flow in the converter in order to homogenize the exhaust gas dispersion in a radial direction, thereby enhancing the hydrocarbon purification performance of the converter.

摘要： An air intake structure is provided with an air intake control valve disposed in the air intake passage. The air intake control valve has a valve element pivotally mounted at one end adjacent to a passage wall of the air intake passage. The air intake control valve is configured to control a gas flow based on the rotational position of the valve element. At least one horizontal partitioning plate extends along the flow direction of an intake air. The horizontal partitioning plate can be stationary or moveable with the valve element. Optionally, the valve element has a swirl-producing notch and a vertical partitioning plate extends substantially perpendicular to the horizontal partitioning plate from a position corresponding to a vertical side edge of the swirl-producing notch when the air intake control valve is fully closed. The vertical partitioning plate can be stationary or moveable with the valve element.

An auxiliary catalytic converter is mounted in the downstream bypass exhaust passage.
