  • Patent number: 10837341
    Abstract: Methods and systems are provided for an exhaust tract for vehicles having an internal combustion engine, the exhaust tract including a first exhaust gas aftertreatment device and a metering device arranged downstream therefrom. In one example, a region of the first exhaust gas aftertreatment device which is situated downstream is designed as an SCR region. Further, the metering device is designed to spray a reducing agent onto a side of the first exhaust gas aftertreatment device which faces the metering device, counter to a main direction of flow of an exhaust gas.

  • Patent number: 10029671
    Abstract: An operating method for a motor vehicle having a hybrid drivetrain includes, during a demand check, comparing at least one value which characterizes a current state of an exhaust-gas after-treatment device, with a setpoint value of the exhaust-gas after-treatment device. In response to the comparison indicating a deviation of the value characterizing the current state of the exhaust-gas after-treatment device from the setpoint value, a demand for a measure is indicated. The measure includes supplying charge gas, which includes recirculated exhaust gas, to the internal combustion engine during overrun operation. In addition, a capability check is carried out to detect conditions suitable for implementing the operating method.

  • Patent number: 9630497
    Abstract: An immobilizer system for a motor vehicle having an starter mechanism and a substance detector for detecting impairing drugs/substances in a driver's bode, the allowing the vehicle to be started/operated only when the substance detector delivers a result which is below a limit value. An electronic controller of the immobilizer system is programmed by the driver to pre-specify which restrictions the starter mechanism is subject to if the substance detector delivers a positive test result (above a limit level). The immobilizer may be programmed to either a) prevent operation of the vehicle, or b) allow operation but present a notification to the driver. The driver may set a future time interval during which a selection of option a) cannot be changed by the driver.

  • Publication number: 20160251012
    Abstract: The present disclosure relates to an operating method for a motor vehicle having a hybrid drivetrain where in a demand check, at least one exhaust-gas after-treatment actual value, which characterizes a current exhaust-gas after-treatment actual state, is compared with an exhaust-gas after-treatment setpoint value, and if, in the event of a deviation of the exhaust-gas after-treatment actual value from the exhaust-gas after-treatment setpoint value, a demand for a measure is detected. The measure comprises supplying charge gas, which has recirculated exhaust gas, to the internal combustion engine during overrun operation. Also a capability check is carried out to detect conditions suitable for implementing the operating method.

  • Patent number: 9416746
    Abstract: A method for operating an internal combustion engine having a lean NOx trap connected downstream is provided. The method comprises in a normal operating mode, operating the internal combustion engine with a lean fuel/air mixture, and in a special operating mode, operating the internal combustion engine with a rich fuel/air mixture in order to bring about regeneration of the lean NOx trap, wherein a changeover from the normal operating mode to the special operating mode takes place when switching off of the internal combustion engine is expected.
