ABSTRACT:
As a device for the purification of exhaust gas, a three-way catalyst A purifying hydrocarbon, carbon monoxide and nitrogen oxide in the vicinity of theoretical air-fuel ratio is disposed at an upstream side of the exhaust gas and an adsorption catalyst B provided with zeolite effective for the adsorption of hydrocarbon is disposed at a downstream side of the exhaust gas.
