Abstract
An exhaust purification apparatus which comprises: a first processing unit for removing particulate matter; a second processing unit for reducing nitrogen oxide; a communication pipe for guiding exhaust from an exhaust outlet of the first processing unit to an exhaust inlet of the second processing unit; and a reducing agent supply unit on the communication pipe. The first and second processing units are arranged in parallel such that the exhaust outlet and the exhaust inlet are on the sides facing each other. The communication pipe is arranged between the first and second processing units where the processing units are closest to each other such that the upstream part of the communication pipe extends from the exhaust outlet along the outer circumferential surface of the first processing unit and the downstream part of the communication pipe extends along the outer circumferential surface of the second processing unit to the exhaust inlet.
