Abstract
An exhaust gas control apparatus for an engine and a method for producing the same are provided. The exhaust gas control apparatus includes a valve portion, an absorption portion, and a catalyst portion. The valve portion includes a valve that opens/closes a main exhaust passage. The absorption portion includes a hydrocarbon-absorbent that absorbs hydrocarbons. The catalyst portion includes a three-way catalyst that purifies exhaust gas. The valve portion, absorption portion, and the catalyst portion are independent of each other. The valve portion, the absorption portion, and the catalyst portion are connected to each other in series. With this configuration, any individual component can be replaced with another corresponding component that achieves a required level of performance while minimizing the number of other components.
