Estimating the term…
An apparatus for the regeneration of a soot-particle filter is located in the exhaust-gas line of an air-compression, fuel-injected internal-combustion engine. The apparatus regenerates the filter using a process which burns off the soot particles in the filter. A device in the intake line is actuable as a function of the engine load and engine speed and controls the cross-section of the intake line. To prevent damage to the soot-particle filter body during a transition of the internal-combustion engine into the deceleration mode, immediately after the transition into the deceleration mode of the internal-combustion engine, the process and apparatus move the device for controlling the intake-line cross-section first out of its open position into a position to reduce the line cross-section to a minimum and thereafter continuously into its open position.
A process for the regeneration of a soot-particle filter in an exhaust-gas line of an air-compression fuel-injected internal-combustion engine by the burning off of the soot particles comprising the steps of:
