EXHAUST GAS CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE MOUNTED ON VEHICLE

摘要

A filter collecting particulate matter in an exhaust gas and a urea supply valve disposed on an exhaust downstream side from the filter and supplying urea water for exhaust gas purification into an exhaust passage are disposed in the exhaust passage of an automotive engine. A control device executes a regeneration processing for regenerating the filter by supplying a fuel into the exhaust passage on an exhaust upstream side from the filter. The control device supplies the urea water from the urea supply valve in a case where an exhaust gas temperature exceeds a predetermined temperature while the regeneration processing for the filter is executed with a vehicle being stopped.
