Method for operating a sensor for recording particles in a gas stream and device for implementing the method

Procedure and device to regenerate an exhaust gas purification system

Method and device for implementing a method for ascertaining the load condition of a component arranged in an exhaust-gas region of an internal combustion engine

Integrated particle sensor operation, e.g. resistive particle sensor, for use in motor vehicle, involves determining exhaust gas flow rate in sensor, and considering cross sensitivity of sensor in comparison with different gas flows

Method for temporarily raising the temperature in the exhaust gas of an internal combustion engine comprises increasing the stream of fresh air and/or exhaust gas passing through bypasses using adjusting elements

Exhaust gas after-treatment system operating method for use in exhaust duct of internal combustion engine i.e. diesel engine, involves implementing regulation of temperature of exhaust gas before particle filter
