  • Automatic regeneration control device for particulate filter
    Patent number: 9850793
    Abstract: An automatic regeneration controller for a particular filter comprises an engine controller, a unit controller, and a load application cancellation switch. With filter regeneration being started by determination of particulate accumulation and with an idling or light-load operation being conducted, load request to a work unit is outputted from the engine controller to the unit controller. Then, when load application is not possible or the load application cancellation switch is on and, in addition, exhaust temperature is not maintainable with no load application, a regeneration stop signal is outputted from the unit controller to the engine controller and a regeneration stop signal reception process is conducted in the engine controller, and with no forced load application to a hydraulic unit, fuel addition is stopped to stop automatic regeneration control.
