摘要： Methods and systems are provided for HP-EGR and LP-EGR. In one example, a method includes selecting a HP-EGR mode or a LP-EGR mode in response to a first difference calculated between ammonia desired during the two modes, and a second difference calculated between NOx emitted during the two modes.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
