摘要： Aspects of the present invention relate to an exhaust system (207) for exhausting combustion gases from an internal combustion engine (101). The exhaust system (207) includes an exhaust conduit (215) for conveying exhaust gases from the internal combustion engine (101). A particulate filter (214) is providing for filtering particulates from the exhaust gases conveyed by the exhaust conduit (207). A supply inlet (216) is arranged to introduce gas into the particulate filter (214) to promote regeneration. The supply inlet (216) is disposed upstream of the particulate filter (214) and downstream of a catalytic convertor (209). A control valve (218) is provided for controlling the supply of gas to the particulate filter (214) to control regeneration. Aspects of the present invention also relate to a vehicle (100) incorporating a controller (104); and a method of controlling operation of the control valve (218) to control regeneration of the particulate filter (214).
