Claims9
A particle filter assembly for a motor vehicle, comprising:
- a particle filter;
- an exhaust-gas-conducting line which opens into the particle filter;
- and
- a secondary air supply, wherein the secondary air supply is formed separately from the exhaust-gas-conducting line and wherein fresh air is suppliable to the particle filter via the secondary air supply, wherein the secondary air supply is not connected in terms of flow to an intake tract of an internal combustion engine, wherein a pump is disposed in the secondary air supply, wherein the pump is a suction jet pump, wherein a throttle valve is disposed in the secondary air supply downstream of the pump in a direction of flow of the fresh air, wherein a measuring section is disposed in the secondary air supply downstream of the throttle valve in the direction of flow of the fresh air, and wherein the particle filter has an exhaust gas inlet and an air inlet and wherein the air inlet is formed separately from the exhaust gas inlet.
