DPF SYSTEM AND METHOD OF DPF REGENERATION OF ENGINE TYPE FORKLIFT TRUCK DURING DRIVING OF VEHICLE

摘要

The present specification relates to a DPF regeneration system and a method thereof during operation of an engine-type forklift, and a DPF regeneration system during operation of an engine-type forklift according to an embodiment of the present disclosure includes PM (Particulate) in exhaust gas discharged from an engine to an exhaust passage A DPF regeneration system during operation of an engine-type forklift including a DPF (Diesel Particulate Filter) for collecting matter, comprising: an engine control unit (ECU) for controlling the operation of the engine; An electro-hydraulic pump that discharges hydraulic oil that generates a hydraulic load; When receiving a DPF regeneration request signal from the engine control unit (ECU), the controller determines the state of the forklift, and controls at least one of the hydraulic load of the electro-hydraulic pump or the number of revolutions of the engine according to the determined state of the forklift ; And a diesel oxidation catalyst device (DOC) that regenerates the DPF under the control of the control unit. According to one embodiment of the present specification, by controlling the load and the engine speed of the electro-hydraulic pump in the engine-type forklift, DPF can be regenerated without forcibly regenerating the DPF during operation of the engine forklift, thereby ensuring the performance and safety of work. have.
