Abstract: A flame detection system is disclosed. The system may have a flame chamber and a filter, wherein the filter includes filter media configured to collect matter from an engine exhaust. Additionally, the filter may be disposed downstream of the flame chamber. An ignition device may be disposed in the flame chamber and may be configured to ignite a flame in the flame chamber to regenerate the filter. A sensor may be disposed proximate the ignition device, and may be configured to sense a change in electrical conductivity that is indicative of a presence of the flame in the flame chamber.

Abstract: An emissions control system includes a Selective Catalytic Reduction (SCR) device, one or more monitoring devices and one or more sensors. The system further includes a controller configured to determine an operating emissions gas conversion ratio of the SCR device. The controller is further configured to determine an injection amount of a reduction agent to maintain an operating emissions gas conversion ratio of the SCR device and to adjust the operating emissions gas conversion ratio to a target emissions gas conversion ratio by adjusting the injection amount of the reduction agent to the SCR device. The system utilizes a Time-Temperature model to determine the target emissions gas conversion ratio and/or reduction agent injection ratio. The system further includes a reduction agent injector configured to supply the adjusted injection amount of the reduction agent to the SCR device.
