Abstract
A catalytic converter arrangement incorporated in an exhaust system of an internal combustion engine includes an exhaust manifold for ducting emissions from the engine; and first and second catalytic converters. The first catalytic converter is connected to and positioned immediately downstream from the exhaust manifold. The first catalytic converter has a ceramic catalyst support on an upstream side thereof and a metal catalyst support on a downstream side thereof. The second catalytic converter is connected to the first catalytic converter through an exhaust pipe and positioned downstream from the first catalytic converter. The second catalytic converter has a ceramic catalyst support. Thus, overheating of the metal catalyst support of the first catalytic converter can be prevented due to absorption of heat from emissions by the ceramic catalyst support of the first catalytic converter.
