Patent ID: 7260927

Claim:
An intelligent, full-featured diesel engine exhaust treatment system for treating engine exhaust discharged by an engine, including an exhaust flowing zone, wherein the exhaust flowing zone comprises separate elements (A, B, C, and D): an intermediate communicating pipe (A), for directing the engine exhaust into the exhaust flowing zone; at least one catalyst converter array (B) to treat hydrocarbon and carbon monoxides in the engine exhaust, said at least one catalyst converter array being directly or indirectly in communication with the intermediate communicating pipe for treating the exhaust from the intermediate communicating pipe; at least one soot filter array (C) to filter soot particles in the engine exhaust, said at least one soot filter array being directly or indirectly in communication with the intermediate communicating pipe for filtering the engine: exhaust from the intermediate communicating pipe; and a main exhaust pipe (D), being directly or indirectly in communication with the at least one soot filter array and said at least one catalyst converter array for discharging the engine exhaust that has been filtered by the at least one soot filter array or treated by the at least one catalyst converter array to atmosphere, wherein: the soot filter array and catalyst converter array are respectively and exclusively constructed to carry out filtering of soot and treatment of hydrocarbons in the engine exhaust, the exhaust flowing zone defines a first exhaust treatment path and a second exhaust treatment path, both the first exhaust treatment path and the second treatment path extending between the intermediate communicating pipe and the main exhaust pipe, the first exhaust treatment path sequentially passes through the intermediate communicating pipe, the at least one soot filter array, and the main exhaust pipe; and the second exhaust treatment path sequentially passes though the intermediate communicating pipe, the at least one catalyst converter array, and the main exhaust pipe; and wherein: the exhaust flowing zone is provided with an exhaust detecting device at an appropriate location for detecting engine exhaust, whereby after the engine exhaust enters the intelligent, full-featured diesel engine exhaust treatment system through the intermediate communicating pipe, a microcomputer processor of the intelligent, full-featured diesel engine exhaust treatment system determines to which of the first exhaust treatment path or the second exhaust treatment path should the engine exhaust be directed based on the engine exhaust data, prior to discharging the engine exhaust into the atmosphere.
