    摘要: Several embodiments of high-efficiency catalytic converters and associated systems and methods are disclosed. In one embodiment, a catalytic converter for treating a flow of exhaust gas comprising a reaction chamber, a heating enclosure enclosing at least a portion of the reaction chamber, and an optional coolant channel encasing the heating enclosure. The reaction chamber can have a first end section through which the exhaust gas flows into the reaction chamber and a second end section from which the exhaust gas exits the reaction chamber. The heating enclosure is configured to contain heated gas along the exterior of the reaction chamber, and the optional coolant channel is configured to contain a flow of coolant around the heating enclosure. The catalytic converter can further include a catalytic element in the reaction chamber.

    摘要: A method and an arrangement for cleaning a particulate filter in a vehicle provided with an internal combustion engine is provided. The particulate filter is mounted in an operative position inside an exhaust muffler under normal operation of the engine. The method involves performing a cleaning process including disassembling and removing the particulate filter from a first end of the muffler; reversing and reassembling the particulate filter a cleaning position at the first end of the muffler; starting and operating the engine by controlling the engine speed according to a predefined cycle until a predetermined condition is fulfilled; and stopping the engine and returning the particulate filter to its operative position inside the exhaust muffler.
