Patent number: 9952124Abstract: A system for taking exhaust gas samples from internal combustion engines includes an exhaust gas duct comprising an outflow cross section and an exhaust gas inlet. The exhaust gas duct communicates with an exhaust gas source via the exhaust gas inlet. An air duct takes in ambient air via a filter. The outflow cross section is concentric in the air duct. A mixing zone is arranged downstream of the outflow cross section. A dilution tunnel has an exhaust gas/air mixture flow therethrough. An annular orifice is arranged downstream of the outflow cross section in the dilution tunnel. A flow deflection device is arranged upstream of the annular orifice and downstream of the outflow cross section. The flow deflection device deflects the exhaust gas/air mixture so that it departs from a center axis of the dilution tunnel immediately downstream of the flow deflection device in an axially symmetrical manner.Type: GrantFiled: March 12, 2013Date of Patent: April 24, 2018Assignee: AVL EMISSION TEST SYSTEMS GMBHInventors: Achim Dickow, Rainer Ballik, Sascha Willich

Patent number: 8820138Abstract: A system for taking an exhaust gas sample includes a first exhaust gas channel fluidically connected to a first exhaust gas source via a first exhaust gas inlet. A first air channel with a first air filter is configured to suck in ambient air. The first exhaust gas channel meets the first air channel in a first mixing zone, where a first exhaust gas is mixed with the ambient air to obtain a diluted exhaust gas/air mixture. A second exhaust gas channel is fluidically connected to a second exhaust gas source via a second exhaust gas inlet, and a second mixing zone. A control device and a measurement device are configured to respectively control and measure mass flows. The diluted exhaust gas/air mixture flows either from the first exhaust gas source or from the second exhaust gas source into the dilution tunnel and to at least one sampling probe.Type: GrantFiled: March 2, 2010Date of Patent: September 2, 2014Assignee: AVL Emission Test Systems GmbHInventor: Achim Dickow

Patent number: 5546788Abstract: A method and apparatus for measuring the concentration of particles in the exhaust gas of an internal combustion engine in which the exhaust gas is mixed and diluted with air in a mixing chamber (6) and supplied to a measuring filter (4) during a measurement phase. In order to establish the dilution ratio of the exhaust gas in the mixture of exhaust gases and air, valves (10, 11) are operated to supply air from an air line (13) to a bypass line (12) during a second phase. The quantity of air flow in the air line (13) is equal to the flow quantity of the exhaust gas to the mixing chamber (6). Thereby, the ratio of the quantity of particles measured by the filter (4) to the air flow in the air line (13) represents the concentration of the particles in the exhaust gas.Type: GrantFiled: January 24, 1995Date of Patent: August 20, 1996Assignee: Pierburg GmbHInventor: Achim Dickow
