摘要：
An exhaust purification apparatus for an engine comprises an upstream casing that has a cylindrical shape and accommodates a particulate filter; an exhaust gas outlet that is formed in a side wall of the upstream casing and discharges the exhaust gas that has passed through the particulate filter; a urea-water injector that is fixed to the upstream casing located in a position opposite to the exhaust gas outlet and injects urea-water toward the exhaust gas outlet; and a downstream casing that accommodates an ammonia selective reduction-type NOx catalyst into which the exhaust gas discharged from the exhaust gas outlet flows.
