초록

A method of diverting flow with a valve through a first filter and a second filter to purify exhaust gas with at least one of the filters and to regenerate at least one of the filters with the exhaust gas. Positioning the valve in a first operative position purifies the exhaust gas with the first filter and regenerates the second filter with the exhaust gas. Positioning the valve in a second operative position that is different that the first operative position purifies the exhaust gas with the second filter and regenerates the first filter with the exha...
