Method of controlling exhaust emission of machine

Abstract

A method of controlling exhaust emission of a machine is provided. The method includes coupling a control unit with an engine of the machine. The method also includes connecting at least one aftertreatment device to the engine of the machine. The at least one aftertreatment device is adapted to control the exhaust emission of the machine. The method further includes receiving, by the control unit, an input signal from the at least one aftertreatment device The method includes identifying the at least one aftertreatment device based on the input signal. The method also includes correlating the input signal with the data stored in the data storage module. The method further includes selecting a mode of operation associated with the at least one aftertreatment device. The method includes controlling the exhaust emission of the machine based on the mode of operation.

What is claimed is: 
     
         1 . A method of controlling exhaust emission of a machine, the method comprising:
 coupling a control unit with an engine of the machine, wherein the control unit comprises a data storage module for storing data associated with operation of one or more aftertreatment devices;   connecting at least one aftertreatment device to the engine of the machine, wherein the at least one aftertreatment device is adapted to control the exhaust emission of the machine:   receiving, by the control unit, an input signal from the at least one aftertreatment device;   identifying the at least one aftertreatment device based on the input signal;   correlating the input signal with the data stored in the data storage module;   selecting a mode of operation associated with the at least one aftertreatment device; and   controlling the exhaust emission of the machine based on the mode of operation.
