Abstract:
1. A control system enabling operator intervention in regeneration cycles for a diesel exhaust particulate filter, the system comprising: a controller area network; an engine controller connected to the controller area network; a diesel engine and exhaust system operating under the control of the engine controller; an ignition switch for controlling on and off states of the diesel engine, a diesel particulate filter connected into the exhaust system, regeneration of the diesel particulate filter occurring by varying engine operation under the control of the engine controller with the engine controller being programmed to initiate regeneration of the diesel particulate filter automatically responsive to particular conditions; and an operator interface providing an operator actuated regeneration inhibit switch and an operator actuated forced regeneration switch and further providing a visual display for indicating regeneration status, the operator interface communicating with the engine controller over the controller area network, the engine controller being responsive an inhibit indication from the operator actuated regeneration switch for suspending automatic response to the particular conditions.
