The system includes a controller to determine one or more aging parameters of the engine, and to control one or more operating parameters of the engine, at least, based on the one or more aging parameters, such that the emissions from the engine are maintained to be substantially constant during a useful life of the engine. Method and non-transitory computer readable media for controlling emissions of an engine are also disclosed. ## Claims ### Claim 1 A system for controlling emissions of an engine, comprising: a controller to determine one or more aging parameters of the engine, control one or more operating parameters of the engine, at least, based on the one or more aging parameters to maintain the emissions from the engine substantially constant during a useful life of the engine, and reset the one or more operating parameters to a corresponding determined value on receiving a reset signal when the engine is overhauled. ### Claim 2 (depends on 1) The system of claim 1, wherein the engine is configured such that, at the beginning of the useful life of the engine, the emissions from the engine are maintained in a range greater than about 80 percent of a target limit and less than the target limit. ### Claim 3 (depends on 1) The system of claim 1, wherein the one or more aging parameters comprise operating hours of the engine, change in the emissions, deviation in a quantity of a fuel being dispensed by a fuel nozzle, or combinations thereof. ### Claim 4 (depends on 3) The system of claim 3, wherein the controller is further configured to receive one or more signals indicative of the emissions, or the quantity of the fuel being dispensed by the fuel nozzle, from one or more sensors. ### Claim 5 (depends on 4) The system of claim 4, further comprising one or more sensors to: generate the one or more signals indicative of the emissions, the quantity of the fuel being dispensed by the fuel nozzle, or combinations thereof; and communicate the generated one or more signals to the controller. ### Claim 6 (depends on 1) The system of claim 1, wherein the one or more operating parameters comprise injection timing, intake oxygen concentration, oxygen to fuel ratio, cylinder pressure, quantity of fuel to be injected, fuel injection pressure, injection pattern, or combinations thereof. ### Claim 7 (depends on 1) The system of claim 1, wherein the engine is an internal combustion engine. ### Claim 8 (depends on 1) The system of claim 1, wherein the engine is a locomotive engine. ### Claim 9 A system, comprising: an engine; and a controller to determine one or more aging parameters of the engine, control one or more operating parameters of the engine, at least, based on the one or more aging parameters to maintain emissions from the engine substantially constant during a useful life of the engine, and reset the one or more operating parameters to a corresponding determined value on receiving a reset signal when the engine is overhauled. ### Claim 10 A method for controlling emissions of an engine, comprising: determining one or more aging parameters of the engine; controlling one or more operating parameters of the engine, at least, based on the one or more aging parameters, such that the emissions from the engine are maintained to be substantially constant during a useful life of the engine; and resetting the one or more operating parameters to a corresponding determined value on receiving a reset signal when the engine is overhauled. ### Claim 11 (depends on 10) The method of claim 10, further comprising maintaining the emissions from the engine in a range greater than about 80 percent of a target limit and less than the target limit. ### Claim 12 (depends on 10) The method of claim 10, wherein the one or more operating parameters comprise injection timing, intake oxygen concentration, oxygen to fuel ratio, cylinder pressure, quantity of fuel to be injected, fuel injection pressure, injection pattern, or combinations thereof. ### Claim 13 (depends on 10) The method of claim 10, wherein the one or more aging parameters comprise operating hours of the engine, change in the emissions, deviation in a quantity of a fuel being dispensed by a fuel nozzle, or combinations thereof. ### Claim 14 (depends on 13) The method of claim 13, further comprising receiving one or more signals indicative of the emissions, or the quantity of the fuel being dispensed by the fuel nozzle, from one or more sensors. ### Claim 15 A non-transitory computer readable media storing an executable code to perform method of: determining one or more aging parameters of an engine; controlling one or more operating parameters of the engine, at least, based on the one or more aging parameters, such that emissions from the engine are maintained to be substantially constant during a useful life of the engine; and resetting the one or more operating parameters to a corresponding determined value on receiving a reset signal when the engine is overhauled. ### Claim 16 (depends on 15) The non-transitory computer readable media of claim 15, further comprising an executable code to maintain the emissions from the engine in a range greater than about 80 percent of a target limit and less than the target limit.
