摘要： An emission control catalyst that exhibits improved CO and HC reduction performance includes a supported platinum-based catalyst, and a supported palladium-gold catalyst. The two catalysts are coated onto different layers, zones, or monoliths of the substrate for the emission control catalyst such that the platinum-based catalyst encounters the exhaust stream before the palladium-gold catalyst. Zeolite may be added to the emission control catalyst as a hydrocarbon absorbing component to boost the oxidation activity of the palladium-gold catalyst.

The filter 19 is formed in a substantially short column-shape and is provided with a central through-hole 21 and a pair of exhaust ducts 26. The filter 19 is situated within an outer cylindrical casing 4 on an axis perpendicular to the axis of the outer cylindrical casing 4. Exhaust gas 1 discharged from a diesel engine flows from an outer periphery 22 side of the filter 19 to the central through-hole 21 side, wherein the carbon particles PM contained in the exhaust gas 1 are captured, burned and reduced. A plurality of filters 19, each formed in a hollow cylinder-shape, can also be provided side by side in the same direction as the axis of the outer cylindrical casing 4.

摘要： In an exhaust gas purification system with a continuous regeneration type DPF device, when a collecting quantity (ΔPm) of PM exceeds a predetermined judgment collecting quantity (ΔPm0), a number-of-regeneration-times coefficient (Rc) serving as an index of the number of regeneration times to a travel distance is compared with a predetermined judgment coefficient value (R0). When the number-of-regeneration-times coefficient (Rc) is smaller than the predetermined judgment coefficient value (R0), automatic traveling regeneration is performed. If this condition is not met, manual regeneration is performed.
