摘要： A diesel engine is provided with a soot particle catcher. When the soot particle catcher is heavy with accumulation of soot, while the engine is operating a combustion chamber thereof is supplied with a purging supply of diesel fuel at a timing point at which heat produced by combustion of this diesel fuel within the combustion chamber is not substantially converted into mechanical work, but is vented to the exhaust system in the exhaust gases substantially completely. Thus the soot catcher is heated up, and is purged by combusting the accumulation of soot particles in it. This timing point may be the later part of the expansion stroke of the piston of the combustion chamber. The amount of this purging fuel supply may be arranged to be just enough completely to use up by combustion all excess oxygen in the combustion chamber at the timing point. Apparatus for performing this method of fuel supply may include first and second fuel injection pumps for supplying the normal type powering fuel injection pulses into the combustion chamber and also for selectively supplying such purging pulses, or may alternatively include a combination fuel injection pump of a novel sort both for supplying such powering pulses and also for selectively supplying such purging pulses.

摘要： This invention provides improvements in method of and apparatus for reducing an emitted amount of particulates by collecting the particulates contained in the exhaust gas from a diesel engine by a trapper. According to the invention, firstly, an excess amount of the particulates which have adhered to the trapper is detected, and thereafter, temperature of the trapper being within a range of self-burning temperature of the particulates is detected. When necessity for regenerating the trapper is ascertained based on the both detections described above, the inlet side of the trapper is heated to a range of igniting temperature of the particulates, whereby a large igniting energy required for propagating combustion is accumulated. Thereafter, secondary air is supplied to the trapper to ignite the particulates, and combustion is propagated to the particulates being within the range of self-burning temperature thereof by the secondary air continuously supplied, to thereby regenerate the trapper.
