Diesel particulate oxidizer regeneration system
In a diesel engine having a fuel injection pump and fuel control means for controlling the injection volume or injection timing of the fuel injection pump, a diesel particulate oxidizer regeneration system is described including: a diesel particulate oxidizer disposed in an exhaust system of the diesel engine and having a trap carrier for collecting unburnt fine particles contained in exhaust gas, a regeneration means for burning the unburnt fine particles collected in the diesel particulate oxidizer; a regeneration timing control means for detecting the quantity of the unburnt fine particles deposited in the diesel particulate oxidizer and providing a signal to the regeneration means for operating the latter when the detected value is above a predetermined value; and a regeneration end control means for detecting that the quantity of the unburnt fine particles collected and deposited in the diesel particulate oxidizer has become less than the predetermined value after combustion, and producing a signal for stopping the operation of the regeneration means.
