Abstract
A system for determining accumulation of Silicone dioxide (SiO) in an aftertreatment system of an engine includes a pressure sensor arrangement having at least one pressure sensor therein. The pressure sensor is fluidly coupled to an exhaust pipe associated with the aftertreatment system. A controller is disposed in communication with the pressure sensor. The controller is configured to monitor back pressure of the aftertreatment system from at least one signal output by the pressure sensor arrangement and determine a level of accumulation of Sift in the aftertreatment system based on the monitored back pressure of the aftertreatment system. Based on the determination of the level of accumulation of Sift in the aftertreatment system by the controller, the controller outputs a signal to a notification device for facilitating the notification device to notify an operator of the level of accumulation of SiOin the aftertreatment system.
