Abstract
A catalytic converter system for purifying exhaust gas from an internal combustion engine has a catalytic converter of the so-called monolithic type having a catalytic body of a honeycomb shape. The body has an elongated cross-sectional-shaped inlet surface located transverse to the flow of exhaust gas. An exhaust pipe of a relatively small diameter has an end facing the inlet of the catalytic body. In order to direct the exhaust gas to the outermost portion of the elongated inlet of the catalytic body, the exhaust pipe is, on the end facing the inlet, provided with a guiding means for forming one opening on each side of the exhaust pipe in the direction along which the inlet of catalytic body is elongated. The exhaust gas in the exhaust pipe is partly diverted therefrom via the side openings toward the outermost peripheral portion of the inlet of the catalytic body. Accordingly, the catalytic converter can be used to effectively purify exhaust gas.
