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.

Flame detection system for particulate filter regeneration

A method of controlling an operation of a mechanism is provided. A first rate limit is assigned to a first input device that is operable to generate a first signal to control the operation of the mechanism. A second rate limit is assigned to a second input device that is operable to generate a second signal to control the operation of the mechanism. At least one of the first and second input devices are manipulated to effect a desired change in the operation of the mechanism. A maximum allowable rate of change in the operation of the mechanism is identified based on the first and second signals and the first and second rate limits. A rate of change in the operation of the mechanism to achieve the desired change in the operation of the mechanism is determined based on a comparison of the maximum allowable rate of change in the operation of the mechanism with a last used rate of change in the operation of the mechanism.

Rate limiting control system

In many applications, it is desirable to have work machines automatically maintain a desired speed and heading. Provided is an electronic control connected with left and right hydraulic motor assemblies that drive left and right ground engaging propulsion mechanisms, left and right speed sensors, and on operator input.
