Abstract (en)
[origin: EP0512246A1] The invention relates to a device for the regeneration of a soot burn-off filter (7) in an exhaust conduit (6) of a diesel engine by means of a fuel/air mixture which is ignited at least partially in the combustion space (3) of at least one cylinder (1) and which, from the combustion space (3), can be directed through a gas passage in the cylinder head (2) in a controlled manner by means of a bypass valve (10) into the exhaust conduit (6) upstream of the soot burn-off filter (7). It is the object of the invention to provide a simple and economical device of this kind which is suitable for reliable ignition of a soot burn-off filter (7) relatively remote from the engine. The object is achieved by virtue of the fact that the bypass valve (10) can be operated by the driver for the purpose of increasing the engine braking power and can be switched to an open position by a control unit (13) as a function of parameters describing the regeneration phase. <IMAGE>
