  • Patent number: 10487715
    Abstract: Embodiments for regeneration a particulate filter in a motor vehicle having a self-control mode for the autonomous control of a drive mode and having a diesel particulate filter disposed in the exhaust system of a diesel engine of the motor vehicle are provided. In one example, a method for protecting the diesel particulate filter from overheating and premature aging comprises: starting the self-control mode, starting/verifying a regeneration process of the diesel particulate filter with combustion of the soot particles adsorbed on the diesel particulate filter, and monitoring a temperature of the diesel particulate filter and/or of the exhaust gas directed through the diesel particulate filter during the regeneration process. Depending on a monitoring result of the monitoring, a control for the self-control mode of the motor vehicle can be adjusted.

  • Publication number: 20190284978
    Abstract: Methods and systems are provided for partially regenerating a lean NOx trap in response to an engine shutdown request. In one example, an engine shutdown is delayed so that a low-temperature storing region of the lean NOx trap is regenerated without regenerating a high-temperature storing region of the lean NOx trap. A battery charge is replenished during the shutdown, wherein the charge may be consumed during a subsequent engine operation.

  • Patent number: 10378404
    Abstract: The present subject matter relates to a method and a treatment system monitor for monitoring an engine exhaust after-treatment system containing more than one Lean NOx Traps (LNT). The method includes receiving an exhaust gas of a desired air-fuel ratio upstream of a respective LNT. The LNT is further regenerated using a richer than stoichiometric exhaust air-fuel ratio and subsequently an air-fuel ratio received downstream of the LNT is evaluated. Further, a working state of a respective LNT is determined based on the monitoring of the air-fuel ratio and oxygen level upstream and downstream of the LNT.

  • Patent number: 10337432
    Abstract: A vehicle and method for controlling a vehicle having a variable displacement engine with an auxiliary machine connected directly to the engine crankshaft and to an energy storage device includes switching from a cylinder disablement (VDE) mode to a normal mode when the torque demand and engine speed lie outside an outer range defined by a first threshold (Tout), and switching from the normal mode to the VDE mode when the torque demand and engine speed lie within an inner range, which lies within the outer range and defined by a second threshold (Tin). When operating in a band between the two thresholds, the auxiliary machine draws energy from the energy storage device and supplements the output torque from the engine if operating in the VDE mode, and derives torque from the engine crankshaft to recharge the energy storage device if operating in the normal mode.

  • Patent number: 10240502
    Abstract: The subject matter of the disclosure relates to a method of diagnosing NOx storage catalyst during the operation of a motor vehicle. The method uses two diagnosis sub-methods having various sensitivities with respect to sulfur contamination of the NOx storage catalyst. The results of the two sub-methods are used to ascertain proportions of aging of the NOx storage catalyst resulting from thermal aging and sulfur contamination.

  • Patent number: 10240505
    Abstract: A method is provided for controlling nitrogen oxide emissions in the exhaust gas of an internal combustion engine by means of successive actuation of catalytic converters in the exhaust tract and of the internal combustion engine, wherein the catalytic converters or the internal combustion engine are actuated in succession if the actuation of a first device is not sufficient for reducing the nitrogen oxide emissions. An arrangement for carrying out the method is also provided.

  • Patent number: 10202945
    Abstract: Embodiments are provided herein for controlling a motor-vehicle internal combustion engine fitted with a fuel injection system and an exhaust gas recirculation system. In one example, in a deceleration phase a closed exhaust gas recirculation circuit is formed, a mass (mcirc) of an air quantity enclosed therein is determined, a first oxygen content (O2,exh1, O2,man1) of the air quantity is detected, a test injection is carried out with an injection valve, a second oxygen content (O2,exh2, O2,man2) of the air quantity is detected, and the fuel mass (mfuel) injected in the test injection is determined from the mass (mcirc) of the air quantity and the first and the second oxygen content (O2,exh1, O2,man1, O2,exh2, O2,man2). The disclosure also relates to a corresponding device for controlling a motor-vehicle internal combustion engine fitted with a fuel injection system and an exhaust gas recirculation system.

  • Patent number: 10040454
    Abstract: A method is provided for controlling a NOx storage catalytic converter that is disposed in the exhaust system of an internal combustion engine of a motor vehicle with an adaptive cruise control system, wherein regeneration of the NOx storage catalytic converter is started depending on the distance to a vehicle ahead. For this the motor vehicle is accelerated in a rich mode for regeneration if the distance to the vehicle ahead is large enough so that the regeneration will be completed during an acceleration phase in which the distance is reduced.

  • 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.
