摘要: Flammable fine particles (particulates) consisting principally of carbon and hydrocarbons are discharged from a diesel engine to its exhaust system. A diesel particulate oxidizer (DPO) is disposed in the exhaust passage for collecting and burning the particulates without allowing the particulates to be discharged directly to the atmosphere.
This DPO comprises a ceramic foam with catalyst When the quantity of particulates collected is above a predetermined value, the DPO will undergo clogging. To prevent this, a high temperature gas containing oxygen is fed to the DPO to burn (regenerate) the collected particulates.
In order to accelerate the normal regeneration of the DPO, there are provided a regeneration means for making a retard control of the fuel injection timing in the diesel engine, and a regeneration timing control means for controlling the operation of the regeneration means.
Further, there is provided a regeneration timing detection means for detecting the regeneration timing of the DPO
Moreover, there is provided a retard inhibition means for inhibiting the retard control for a fuel injection timing adjusting means by the regeneration timing control means according to the engine operating condition.
Additionally, there are provided a forced regeneration control means forcibly regenerating the DPO under a predetermined operating condition of the engine at a regeneration timing, and a particulate combustion suppressing means for suppressing the combustion of the particulates-
