Abstract: An exhaust system (16) of a diesel engine (10) has a diesel particulate filter (18) for treating exhaust gas. When trapped soot has accumulated to an extent that may affect performance of the filter, an engine control system (12) forces combustion of trapped soot by increasing exhaust back-pressure using a control device (20) such as a back-pressure control valve or vanes of a variable geometry turbocharger.

Abstract: A control system (Figure 4) for controlling regeneration of a DPF (42) comprises a favorable-condition-based control section (52), a regular control section (54), and a regeneration termination control section (56). Section (54) initiates regeneration when the actual soot loading (CDPF_DELTA_P) of the DPF becomes sufficiently large to mandate initiation of regeneration. Section (52) initiates regeneration when the actual soot loading (CDPF_DELTA_P) reaches an amount (SOOTLOADING) less than the amount at which section (54) mandates regeneration, provided that selected engine operating conditions (MFDES, ENGINE_SPEED) disclose conditions favorable for regeneration. Section (56) terminates regeneration when soot loading (CDPF_DELTA_P) is reduced to some minimum amount (DELTA_P_MIN) or when conditions for continuing regeneration become unfavorable. By burning trapped soot during favorable conditions, the mandatory regeneration is postponed. This can lower the average amount of trapped soot in the CDPF, thereby lowering the average back-pressure on the engine (20).
Abstract translation: 用于控制DPF（42）的再生的控制系统（图4）包括有利条件的控制部分（52），常规控制部分（54）和再生终止控制部分（56）。 当DPF的实际烟灰负载（CDPF_DELTA_P）变得足够大以致授权再生开始时，部分（54）启动再生。 如果选择的发动机运行条件（MFDES，ENGINE_SPEED）公开了有利于再生的条件，则当实际烟炱负载（CDPF_DELTA_P）达到小于部分（54）强制再生的量的量（SOOTLOADING）时，部分（52）开始再生。 当烟炱装载（CDPF_DELTA_P）减少到一些最小量（DELTA_P_MIN）时，或当持续再生的条件变得不利时，部分（56）终止再生。 通过在有利条件下燃烧捕获的烟灰，强制性再生被推迟。 这可以降低CDPF中的平均烟灰量，从而降低发动机（20）的平均背压。

Abstract: Un sistema de control (Figura 4) para controlar la regeneracion de un filtro de particulas de diesel (DPF) (42) comprende una seccion (52) de control basada en una condicion favorable, una seccion (54) de control regular, y una seccion (56) de control de terminacion de regeneracion. La seccion (54) inicia la regeneracion cuando la carga de hollin real (CPDF_DELTA_P) del DPF llega a ser suficientemente grande para mandar la iniciacion de la regeneracion. La seccion (52) inicia la regeneracion cuando la carga del hollin real (CDPF_DELTA_P) llega a una cantidad (SOOTLOAADING) menor que la cantidad a la cual la seccion (54) ordena la regeneracion, siempre y cuando las condiciones (MFDES, ENGINE_SPEED) revelen condiciones favorables para la regeneracion. La seccion (56) termina la regeneracion cuando la carga del hollin (CDPF_DELTA_P) se reduce a alguna cantidad minima (DELTA_P_MIN) o cuando las condiciones para continuar la regeneracion llegan a ser desfavorables. Por quemar el hollin atrapado, durante las condicione favorables, se pospone la regeneracion obligada. Esto puede disminuir la cantidad promedio del hollin atrapado en el CDPF, disminuyendo asi la retropresion promedio en el motor (20).
