ABSTRACT:
In the regeneration of a filter which filters and collects exhaust-gas particles contained in exhaust gases of an internal combustion engine by combustion, two injection pipes for pressure feeding a fuel to a fuel injection nozzle from a fuel injection pump for a plurality of cylinders are selected, and a proper amount of a pressurized fuel passing through one injection pipe is jetted to a cylinder in the end of an expansion stroke or in an exhaust stroke through another injection pipe, by controlling a changeover valve, and it is discharged to the exhaust of the engine in the unburnt or burnt condition. A valve capable of varying the flowrate is used as the changeover valve.
