    摘要： 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.

    摘要： An arrangement for removing soot particles from the exhaust stream of a diesel internal combustion engine in such a manner that the soot particles are caught between conductor elements disposed at different potential, produce a short circuit and thereby burn off. In order to be able to realize a purification of the exhaust gas stream without a significant increase of the exhaust gas counterpressure, a centrifugal separator is connected to the exhaust gas line, which passes over into a soot particle collecting chamber constructed axially symmetrical to the longitudinal axis thereof; a predetermined number of electrodes is arranged in turn in the soot particle collecting chamber at a slight distance to the casing interior surface whereby the electrodes among one another or the electrodes and the soot particle collecting chamber itself are at a different potential.

    摘要： A fuel-injected internal combustion engine wherein fuel is injected in dependence upon a quantity or volume of air supplied to the engine. A throttle valve controls the airflow rate with an O.sub.2 probe, arranged in an exhaust manifold, controlling a timing valve through a control device for enabling a timed relief of injection pressure of the fuel. An ignition starter switch is connected to the control device in such a manner that the timing valve is fully open during an operation of the ignition starter switch so as to enable a starting boost. An adjustable timing member is coupled to an operating switch provided in the control device, which operating switch closes automatically after a termination of the starting process. The timing member maintains the timing valve in a fully open position during a specific time span so as to provide for an after-start boost. An additional timing member is adapted to maintain the timing valve in a fully open position during a short time span so as to enable an acceleration enrichment. The control device renders the start boost, after-start boost, and acceleration enrichment ineffective upon the probe reaching its normal operating temperature.
