ジンの窒素酸化物除去機構。[Claims for Utility Model Registration] (1) A branch pipe branching from the exhaust pipe of a diesel engine, a switching means for switching the flow of exhaust gas to the branch pipe, and a switching means connected to the branch pipe for switching the flow of exhaust gas to the branch pipe. Nitrogen oxide removal for a diesel engine, comprising a catalytic converter filled with a TiO 2 catalyst for reducing NOx with NH 3 and an NH 3 supply means for supplying NH 3 upstream of the catalytic converter. mechanism. (2) The switching means is characterized in that the switching means is controlled so that the exhaust gas flows into the branch pipe when the exhaust gas of the diesel engine has a low black smoke content or when the exhaust temperature is suitable for the catalyst. A nitrogen oxide removal mechanism for a diesel engine according to claim 1 of the utility model registration.
