Abstract:
The present invention relates to a catalyst purification device for the engine of a vehicle capable of purifying ammonia slip using an ammonia oxidation catalyst (AOC) according to the structure of an exhaust gas path and a control method thereof. More specifically, the present invention can oxidize the ammonia slip used not to be oxidized to a catalyst or an SCR catalyst by purifying the ammonia slip of exhaust gas caused from an engine for a vehicle, which is operated by each of fuel for a spark ignition engine and liquid ammonia fuel or mixing them, using an AOC catalyst device according to the set conditions of a vehicle and the exhaust gas, and can emit the lower amount of NOX caused when ammonia is oxidized than the emission standard of harmful ingredients of the exhaust gas because the minimum amount of the NOX is emitted to the outside by purifying the NOX using a second catalyst device; thereby preventing environmental contamination. Also, the present invention can minimize the amount of the ammonia emitted to the atmosphere since the activation hours of the catalyst is reduced by positioning an AOC catalyst close to the engine with a primary catalyst, and can extend the life of the catalyst since the catalyst is protected by changing the path if there is a possibility that the AOC catalyst is damaged by the high temperature of the exhaust gas.
