ABSTRACT:
An internal combustion engine system has an internal combustion engine with an intake for air and an exhaust for products of combustion. The engine has a turbocharger for pressurizing intake air in response to passage of the products of combustion. An exhaust aftertreatment device receives the exhaust from the engine to filter diesel particulates. A device for regenerating the exhaust aftertreatment device has a feed line and nozzle for injecting duel upstream of the exhaust aftertreatment device on a periodic basis. A system and method for purging the fuel line and the nozzle utilizes pressurized air from the engine turbocharger via an air tank when the regenerating device is not injecting fuel.
