Abstract
A first selective reduction catalyst including a silver-based catalyst is provided in an exhaust pipe of an engine. An ozone generation device generates ozone by using oxygen in the atmosphere, and a hydrocarbon-based liquid supply device supplies a hydrocarbon-based liquid. A part of NO in the exhaust gas flowing through the exhaust pipe is oxidized to NOwith the ozone generated by the ozone generation device, and said NOis supplied to the first selective reduction catalyst. Also, a part of the hydrocarbon-based liquid supplied by the hydrocarbon-based liquid supply device is partially oxidized, with ozone generated by the ozone generation device, to an active reducing agent including an oxygen-containing hydrocarbon such as aldehyde, and this active reducing agent is supplied to the first selective reduction catalyst.
