  • Patent number: 10138835
    Abstract: A vehicle comprising a (diesel or gasoline) engine and aftertreatment system includes a powertrain control unit that identifies engine operating conditions expected to fulfill a demand for output from the engine. A first operating condition is expected to fulfill the demand with an exhaust stream having a first amount of NOx. A second operating condition is expected to fulfill the demand with an exhaust stream having a reduced amount of NOx as compared to the first amount of NOx. The powertrain control unit receives duty cycle information to control the engine to fulfill the demand per the second operating condition, yielding the reduced amount of NOx in the exhaust. Duty cycle information may include vehicle speed, location, a position sensor, a rotation sensor, ambient temperature, a characteristic feature of the duty cycle, dependency of load vs. time, information regarding an historical duty cycle, and temporal dependence of demand.

  • Patent number: 10125701
    Abstract: A method for operating an internal combustion engine using an external exhaust-gas recirculation device with a recirculation setting device to set the flow rate of the recirculated exhaust gas and using a closing time setting device to adjust the closing time of the at least one inlet valve of the internal combustion engine. For the reduction of nitrogen oxides emitted by the internal combustion engine, it is possible, by way of the closing time setting device, for a nitrogen oxide reduction cycle to be set in which the at least one inlet valve of the internal combustion engine closes earlier or later than in the basic cycle.
