20140093434 | Metering System - The invention relates to an electronically controlled metering system having at least one sensor for injection of a reducing agent, especially a urea solution, into the exhaust gas stream of an internal combustion engine for selective catalytic reduction, the metering system being connected/connectable to a tank from which the reducing agent can be taken, the reducing agent being conveyed by means of a pump, the metering system having a first line which carries the reducing agent and the metering system having a compressed air supply and a second line which carries compressed air and at least one nozzle which is coupled to both lines and by which the reducing agent together with the compressed air can be injected into the exhaust gas stream, the metering system in the line which carries the reducing agent having at least one damping element for equalization of pressure fluctuations. | 04-03-2014 |
20150047327 | COMPONENT CARRIER FOR A DOSING SYSTEM - A component carrier of a dosing system including a plurality of components for injecting a urea solution into the exhaust gas flow of an internal combustion engine comprises a base plate forming the component carrier, a plurality of inner flow channels integrated into the base plate, and an inlet port and an outlet port connecting the inner flow channels with the coolant circuit of the internal combustion engine. The component carrier is heated by flowing a fluid having an elevated temperature and circulating in the coolant circuit from the inlet port to the outlet port passing through the inner flow channels and transferring the heat from the fluid to the component carrier. The components of the dosing system mounted on the component carrier and in thermal contact with the component carrier are heated by heat transfer from the heated component carrier. | 02-19-2015 |
