  • Particle filter assembly for a motor vehicle, motor vehicle, and method for regenerating a particle filter
    Patent number: 11635008
    Abstract: A particle filter assembly for a motor vehicle includes a particle filter, an exhaust-gas-conducting line which opens into the particle filter, and a secondary air supply. The secondary air supply is formed separately from the exhaust-gas-conducting line and fresh air is suppliable to the particle filter via the secondary air supply.
    Type: Grant

  • Exhaust gas routing system having an actuable exhaust gas turbine
    Patent number: 10914248
    Abstract: A method and system for controlling temperature in an exhaust gas routing system of an internal combustion engine is provided. The exhaust gas routing system includes an exhaust gas manifold, an exhaust gas turbine which includes an electric machine arranged downstream of the exhaust gas manifold in the exhaust gas stream, an aftertreatment system arranged downstream of the exhaust gas turbine, and a control means configured to control the operation of the electric machine to adapt an operating mode of the exhaust gas turbine between motor operating, regeneration operating and neutral operating modes control means (50) such that the temperature of the aftertreatment system is controlled based on a target temperature.

  • Internal-combustion engine having a cooled exhaust gas recirculation system as well as an exhaust gas manifold
    Patent number: 7841323
    Abstract: An internal-combustion engine contains at least one piston/cylinder unit containing a combustion chamber, having an intake path leading into the combustion chamber, an exhaust gas path leading out of the combustion chamber, and having an exhaust gas manifold. An exhaust gas recirculation path leads from the exhaust gas manifold into the intake path. A cooling device is provided for cooling the recirculated exhaust gas, wherein the cooling device cools the exhaust gas manifold, and the exhaust gas recirculation path branches off the cooled exhaust gas manifold.
