    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.

    摘要： A method of operating a diesel engine assembly having a combustion chamber is disclosed. The method includes the step of determining a desired level of NO.sub.x for exhaust gases exiting the combustion chamber and generating a fuel control signal in response thereto. The method further includes the steps of injecting an amount of combustor fuel into a combustor based on the fuel control signal and combusting the amount of combustor fuel in the combustor so as to produce combustion products. The method yet further includes the steps of advancing the combustion products into the combustion chamber during an intake stoke of the diesel engine and injecting diesel fuel with a fuel injector into the combustion chamber while the combustion products are located in the combustion chamber during a compression stroke. The method still further includes the step of combusting a mixture of the diesel fuel and the combustion products so as to produce exhaust gases during a power stroke. An engine assembly is also disclosed.

    摘要： Internal combustion engines have been developed having regeneration mechanisms for increasing efficiency and reducing emissions. Previous regeneration mechanisms have been complicated and costly. The present invention provides a simple regeneration member which is attached within a piston assembly.
