  • Patent number: 9567856
    Abstract: An apparatus for extracting energy from a fluid flow including a secondary fluid channel, a fluid driveable generator unit and a primary fluid channel. The primary fluid channel comprises a fluid intake in fluid communication with a throat. The throat is configured to increase the flow velocity and reduce the pressure of the primary fluid flowing through the primary fluid channel and includes at least one plenum in the interior of the throat configured to further reduce the pressure of the primary fluid flowing through the primary fluid channel. The plenum includes at least one perforation through its exterior surface in fluid communication with the secondary fluid channel. As such, the flow of primary fluid through the primary fluid channel draws the secondary fluid into the primary fluid channel through the secondary fluid channel and the perforation and thereby into driving engagement with the generator.

  • Patent number: 9567891
    Abstract: A method is disclosed for controlling a concentration of oxygen that is measured by an oxygen sensor of an after-treatment system of an internal combustion engine when a regeneration of an after-treatment device is required. The method may be a computer-implement method. An oxygen sensor target value is lowered in a stepped phase as a function of an exhaust gas flow speed as the exhaust gas passes through the after-treatment system. The oxygen sensor target value is lowered evenly as a function of the exhaust gas flow speed and by a filter phase when a measured air/fuel ratio value is less than or equal to an AFR threshold value and until the oxygen sensor target value is equal to an oxygen sensor final target value. The oxygen concentration is controlled by applying the oxygen sensor target value.

  • Patent number: 9562452
    Abstract: A method for controlling regeneration within an after-treatment component of an engine comprises receiving a signal indicative of whether the engine is in an operating state or a non-operating state and detecting, based on the signal, when the engine has departed an operating state and entered a non-operating state. When the engine has departed an operating state and entered a non-operating state, a regeneration event is initiated. The regeneration event comprises causing a stream of air to flow through the after-treatment component and initiating a flow of fuel into the stream of air.
