Abstract
An aftertreatment system includes a filtration and reduction unit. The filtration and reduction unit comprises a housing defining an internal volume. A filter is disposed in the internal volume and is configured to substantially remove particulates from the exhaust gas. A selective catalytic reduction system is disposed in the internal volume downstream of the filter and is configured to selectively reduce a portion of the exhaust gas. A first catalyst is formulated to oxidize at least a portion of the exhaust gas. An intake pipe is disposed upstream of the filtration and reduction unit and configured to communicate the exhaust gas to the filtration and reduction unit. The first catalyst is disposed in the intake pipe. An exhaust pipe is disposed downstream of the filtration and reduction unit.
