Patent number: 8615985Abstract: A method for providing a reducing agent-containing gas flow in the exhaust system of an internal combustion engine includes providing at least one reducing agent precursor, evaporating the precursor to provide a gas flow, at least partially heating the gas flow to temperatures of at least 250° C., at least partially converting the precursor in the gas flow to a reducing agent and adding the reducing agent-containing gas flow to the exhaust of the engine. The method and a device provide a reducing agent-containing gas flow in a quantity being easily controllable and adaptable to dynamic changes especially in exhaust systems of mobile applications such as automobiles. A temperature of a first zone is kept at 150° C. or just below while a temperature of a second zone is kept at more than 300° C. A hydrolysis catalytic converter is hardly cooled upon receiving the precursor as a vapor, positively affecting the method.Type: GrantFiled: April 1, 2009Date of Patent: December 31, 2013Assignee: EMITEC Gesellschaft fuer Emissions Technologies mbHInventors: Rolf Brück, Peter Hirth, Thomas Härig, Marc Brugger

Patent number: 8407990Abstract: An evaporation unit for evaporating an aqueous solution including at least one reducing agent precursor, includes at least one evaporator cavity defined by a wall made of a material containing titanium. A heat-imparting layer disposed outside the evaporator cavity is made of a material having a thermal conductivity of at least 100 W/mK (Watts per meter and Kelvin) and is connected to the evaporator cavity in a heat-conducting manner. A heating layer disposed outside the heat-imparting layer is connected in a materially integral manner to the heat-imparting layer. The evaporator unit can be controlled in a highly dynamic manner, thereby enabling a sufficiently high amount of ammonia to be produced even during rapid load changes and consequently significant increases in the concentration of nitric oxide in the exhaust gas of the internal combustion engine. A device and a motor vehicle having the evaporation unit are also provided.Type: GrantFiled: August 30, 2010Date of Patent: April 2, 2013Assignee: EMITEC Gesellschaft fuer Emissionstechnologie mbHInventors: Rolf Brück, Jan Hodgson, Sven Schepers, Christian Vorsmann, Marc Brugger

Patent number: 8357332Abstract: A device for evaporating at least one of the following reactants: a reducing agent precursor solution and a reducing agent precursor, includes at least one electrically heatable heating zone having at least one electrically operable heating element with a heating resistor that is self-regulated about a significant temperature. A method and the device for evaporating a reactant allow a simple control of an evaporation process, especially of a urea/water solution, to provide a reducing agent, especially in an SCR process. The heating resistors have a significant temperature that corresponds to a control temperature of the heating resistor. The need for additional control electronics can be removed by adjusting a correspondingly steep curve within a range.Type: GrantFiled: April 2, 2009Date of Patent: January 22, 2013Assignee: EMITEC Gesellschaft fuer Emissionstechnologie mbHInventors: Rolf Brück, Peter Hirth, Thomas Härig, Marc Brugger

Patent number: 8155509Abstract: A device and method for providing a gaseous substance mixture which includes at least one reducing agent and/or at least one reducing agent precursor, includes a reservoir for an aqueous solution which includes at least one reducing agent precursor that can be flow connected to an evaporator chamber, and a device for dosing the aqueous solution in the evaporator chamber. A device can heat the evaporator chamber to a temperature higher than or equal to a critical temperature, in which the aqueous solution is at least partially evaporated. The device and method enable reducing agent to be provided for selective catalytic reduction of nitrogen oxides in the exhaust of an internal combustion engine. Preferably, an evaporator unit is configured as the evaporator chamber and a hydrolysis catalytic converter is disposed outside the exhaust system. As a result, the size of the hydrolysis catalytic converter is reduced, allowing compact construction.Type: GrantFiled: November 17, 2008Date of Patent: April 10, 2012Assignee: Emitec Gesellschaft fuer Emissionstechnologie mbHInventors: Rolf Brück, Marc Brugger, Thomas Härig, Peter Hirth, Ulf Klein

Patent number: 7986870Abstract: A device and a method for providing a gaseous substance mixture including at least one of a reducing agent and/or a reducing agent precursor, include a reservoir for an aqueous solution including at least one reducing agent precursor, from which the aqueous solution can be delivered into at least one metering line having a dispensing opening by a delivery device, and a device for heating the metering line above a critical temperature greater than the boiling temperature of water. Complete evaporation of an aqueous solution including urea and subsequent hydrolysis to form a substance mixture including ammonia, are carried out. The substance mixture is metered as a reducing agent into an SCR catalytic converter. Carrying out the evaporation outside the exhaust system uses considerably smaller hydrolysis catalytic converters, which is space-saving and cost-saving compared to conventional devices for providing a reducing agent for selective catalytic reduction of nitrogen oxides.Type: GrantFiled: November 17, 2008Date of Patent: July 26, 2011Assignee: Emitec Gesellschaft fuer Emissionstechnologie mbHInventors: Rolf Brück, Marc Brugger, Thomas Härig, Peter Hirth, Ulf Klein
