Internal combustion engine system and method |
摘要 |
<p>An internal combustion engine system has an internal combustion engine (10) with an intake for air and an exhaust for products of combustion. The engine (10) has a turbocharger (12) for pressurizing intake air in response to passage of the products of combustion. An exhaust aftertreatment device (32) receives the exhaust from the engine (10) to filter diesel particulates. A device for regenerating the exhaust aftertreatment device (32) has a fuel line (54) and nozzle (38) for injecting fuel upstream of the exhaust aftertreatment device (32) on a periodic basis. A system and method for purging the fuel line (54) and the nozzle (38) utilizes pressurized air from the engine turbocharger (12) via an air tank (62) when the regenerating device is not injecting fuel.</p> |
