Motor vehicle e.g. passenger car, has shaft, bearing shells and bearing ring that are supplied with liquid medium of exhaust gas after-treatment device by lubricant supply device, where medium is supplied as lubricant

摘要

The vehicle has an exhaust gas after-treatment device for loading exhaust gas of an internal combustion engine e.g. petrol engine and diesel engine, of the vehicle with liquid medium i.e. aqueous urea solution, for denitrification of the exhaust gas. A shaft (14), bearing shells (32, 34, 42, 44) and a bearing ring (38) are moved relative to each other and supplied with the liquid medium of the exhaust gas after-treatment device by a lubricant supply device, where the medium is supplied as lubricant. The aqueous urea solution comprises 33 percent of urea contents. An independent claim is also included for a method for operating a motor vehicle.
