摘要： An exhaust gas heating system and method of a direct injection compression ignition internal combustion engine which has a plurality of combustion chambers, an exhaust passage, and one or more direct fuel injection devices, each operable to inject fuel directly into a corresponding one of the combustion chambers. The system also includes a fuel injection controller which is operable to provide to at least one of the direct fuel injection devices, a post fuel injection signal during a corresponding cylinder cycle of the corresponding one of the plurality of combustion chambers. The post fuel injection signal is timed so as to provide exhaust gas heating from a resultant post fuel injection, and the fuel injection controller dynamically determines the particular one or more of the plurality of direct fuel injection devices to which the post fuel injection signal will be applied based on a temperature related engine operating parameter such as a desired amount of exhaust gas heating. The post fuel injection may also be timed and/or shaped such that it does not produce a substantial amount of mechanical energy but instead produces heated exhaust gasses.
