Urea-containing liquid transferring device for nitrogen oxide reduction of exhaust gas of internal combustion engine of motor vehicle, has container accommodating liquid, where container has rib unit that is arranged in sections in channel

摘要

The device (1) has a flow channel (2) for exhaust gas of a motor vehicle, and a container (3) for accommodating urea-containing liquid, where the container has a rib unit (5) for heat transfer between the exhaust gas and the urea-containing liquid. The rib unit is arranged in sections in the flow channel. The rib unit is formed as flow channel-like and/or has a rib wall and/or is formed in sections as a collection chamber for gaseous ammonia-containing mixture. Independent claims are also included for the following: (1) a system comprising a device for transferring urea-containing liquid into gaseous ammonia-containing mixture (2) a method for nitrogen oxide reduction of exhaust gas of a internal combustion engine for a motor vehicle.
