Title:
ATMOSPHERIC AIR PURIFICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/125416
Kind Code:
A1
Abstract:
This atmospheric air purification apparatus is mounted to a vehicle and purifies air in the atmosphere flowing in from the outside of the vehicle. The apparatus is mounted to the vehicle so as to be able to transfer heat from an exhaust manifold that collects exhaust gas discharged from each of the cylinders of an engine of the vehicle. The atmospheric air purification apparatus may comprise a catalyst device which includes a catalyst and purifies the air in the atmosphere flowing in from the outside of the vehicle. The catalyst may be a three-way catalyst and/or an oxidation catalyst. The purification apparatus may be mounted so as to be able to transfer heat from the exhaust manifold so that the temperature of the catalyst rises to 200°C or higher while the vehicle is traveling. The catalyst device may be mounted so as to surround at least a portion of the exhaust manifold. The catalyst device may be mounted so as to be in contact with or spaced apart from the exhaust manifold. The air purification apparatus may further include a guide pipe for guiding the air in the atmosphere outside the vehicle into the catalyst device. In some embodiments, the purification apparatus can be installed inside an engine room of the vehicle.
