  • Patent number: 9581099
    Abstract: An exhaust diagnostic system. The system includes a diesel engine having an exhaust system with a diesel particulate filter (DPF), a diesel oxidation catalyst (DOC), a selective catalytic reduction (SCR) catalyst, a first NOx sensor located upstream of the SCR catalyst and a second NOx sensor located downstream of the SCR catalyst. In addition, an engine control unit (ECU) is in electronic communication with the first NOx sensor and the second NOx sensor. An SCR coordinator can be included and be configured to execute a non-intrusive SCR deNOx efficiency test, an intrusive SCR/DOC deNOx efficiency test and an intrusive DOC non-methane hydrocarbon (NMHC) conversion efficiency test on the exhaust system. As a result of the conversion efficiency tests, a distinction can be made as to whether the SCR catalyst or DOC is failing.

  • Patent number: 9574482
    Abstract: A method of operating components for exhaust gas after-treatment disposed in the exhaust gas tract of a turbocharged internal combustion engine. A partial exhaust gas stream is removed from the main exhaust gas stream upstream of at least one exhaust gas turbine. The partial exhaust gas stream is fed back into the main exhaust gas stream downstream of the at least one exhaust gas turbine.

  • Patent number: 9567869
    Abstract: The invention relates to a method for detecting icing and other loadings on blades of wind turbines. Advantageously, the method utilizes existing wind turbine actuators, for example pitch actuators, far excitation of blade vibrations.

  • Patent number: 9567975
    Abstract: A method for operating a wind turbine (10). The wind turbine (10) is operated with variable rotational speed between predeterminable minimum and maximum rotational speeds. A characteristic variable (51) of an oscillation of the wind turbine (10) is detected. The wind turbine (10) includes a tower (14) and a rotor (13). An open-loop or closed-loop control device (36, 50) provides open-loop control or closed-loop control of the rotational speed of the rotor (13) between a minimum rotational speed and a maximum rotational speed during a power-supplying operation of the wind turbine. A sensor (40) detects a characteristic variable (51) of an oscillation of the wind turbine (10) and the minimum rotational speed is changed depending on the characteristic value (51) of the oscillation. The minimum rotational speed is altered depending on the characteristic variable (51) of the oscillation by the open-loop or closed-loop control device (36, 50).

  • Patent number: 9567889
    Abstract: In an internal combustion engine, an exhaust purification catalyst and a hydrocarbon feed valve are arranged in an exhaust passage. When the air-fuel ratio of the exhaust gas which flows into the exhaust purification catalyst should be made rich, rich control, which makes the air-fuel ratio of the exhaust gas which is exhausted from the combustion chamber rich, is performed. In order to prevent clogging of the hydrocarbon feed valve, clogging preventing injection which injects hydrocarbons from the hydrocarbon feed valve by an injection interval ?tCB is performed. The exhaust purification catalyst has an oxygen storage ability. At the initial period of rich control, clogging preventing injection is performed by a shorter injection interval ?tCS.
