Claims22
A diesel oxidation catalyst, comprising:
- an inlet side having an inlet face;
- an outlet side;
- and
- at least one channel extending from the inlet side to the outlet side, the channel comprising a first, non-catalyzed portion extending from the inlet face to a second, catalyzed portion.
A method of treating engine exhaust gas, comprising introducing gas exhausted from the engine o a channel of a diesel oxidation catalyst, the channel extending from an inlet side to an outlet side of the diesel oxidation catalyst, the inlet side having an inlet face, the channel comprising a first, non-catalyzed portion extending from the inlet face to a second, catalyzed portion.
A diesel oxidation catalyst, comprising:
- an inlet side;
- an outlet side;
- and
- at lest one channel extending from the inlet side to the outlet side and open at the inlet side and the outlet side, the channel comprising a first, non-catalyzed portion extending from the inlet side to a second, catalyzed portion.
A method of treating engine exhaust gas, comprising introducing gas exhausted from the engine into a channel of a diesel oxidation catalyst, the channel extending from an inlet side to an outlet side of the diesel oxidation catalyst and open at the inlet side and the outlet side, the channel comprising a first, non-catalyzed portion extending from the inlet side to a second, catalyzed portion.
