Abstract:
Methods and systems are provided for filtering particulate matter in an exhaust passage of an engine system. In one example, a method may include during a cold start condition comprising an engine temperature being less than a threshold engine temperature, directing engine exhaust gas to an exhaust particulate filter, and during a warm engine condition, directing engine exhaust gas to bypass the exhaust particulate filter, wherein the warm engine condition comprises the engine temperature being greater than or equal to the threshold engine temperature and fuel being combusted in the engine. In this way, the exhaust particulate filter may be reliably regenerated during engine shutdown events such as DFSOs while reducing filter degradation, and lowering PM emissions.

Claim (Index 9):
A method, comprising:\n in response to an engine temperature being greater than a threshold engine temperature,\n directing exhaust gas to bypass an exhaust particulate filter during engine fuel combustion, and \n heating the exhaust particulate filter when an exhaust particulate filter temperature decreases below a threshold filter temperature; and \n in response to the engine temperature being less than the threshold engine temperature,\n directing exhaust gas to the exhaust particulate filter and stopping the heating of the exhaust particulate filter.
