A method for regenerating an Otto particle filter of an internal combustion engine of a vehicle includes identifying a loading state of the Otto particle filter above a regeneration threshold and operating the internal combustion engine in a heating mode for the purposes of heating the Otto particle filter to a temperature threshold. The method further includes switching a first cylinder of the internal combustion engine from a fuel supply to an air supply, and continuing to operate at least one further cylinder of the internal combustion engine with the fuel supply.

Method for regenerating an Otto particle filter of an internal combustion engine of a vehicle

A method for operating an internal combustion engine () that has at least one cylinder row () with first and second exhaust-gas turbochargers (). Charge air is provided by the first exhaust-gas turbocharger () in single-charger operation, but is provided by the first and second exhaust-gas turbocharger () in two-charger operation. To switch from single-charger to two-charger operation above a load threshold value of the internal combustion engine (), when a speed of the internal combustion engine () reaches or overshoots a threshold value, a charge pressure is increased to build up a torque reserve and a charge pressure reserve and to maintain a driver demand torque. When the charge pressure reaches or overshoots a threshold value, a switch is made from single-charger operation to two-charger operation, and subsequently, the torque reserve and the charge pressure reserve are eliminated.

Method and control device for operating an internal combustion engine

A method for controlling an internal combustion engine of a motor vehicle includes interrupting a fuel supply in an overrun mode of the motor vehicle above a switch-off rotational speed of the internal combustion engine. The fuel supply is switched on again when a starting rotational speed (n1) is reached or undershot. A brake pressure gradient of a brake system of the motor vehicle is detected and the starting rotational speed (n1) is varied as a function of the brake pressure gradient.

Method and device for controlling an internal combustion engine

A control device of a motor vehicle having a noise transmission system and an exhaust system, wherein the noise transmission system has, for manipulating an interior noise of the motor vehicle, at least one intake noise transmission device which can be coupled via a first tubular connecting element to an air intake pipe leading to an internal combustion engine, the first tubular connecting element being assigned a switchable shut-off device, and which can be coupled via a second tubular connecting element to a vehicle interior, wherein the exhaust system has at least one switchable shut-off device for manipulating an exterior noise of the motor vehicle, and wherein the control device manipulates the operation of the noise transmission system and of the exhaust system jointly as a function of an actuation of a common operating element by the driver.
