    摘要： PURPOSE: A diesel particulate filter (DPF) automatic control device and a control method thereof are provided to make a separate regenerative process unnecessary by automatically performing the regenerative process of a DPF before a car engine stops. CONSTITUTION: A diesel particulate filter (DPF) automatic control device comprises a driving information detection unit (120), a storage unit (130), a driving pattern extracting unit (140), a time setup unit (150), a control unit (170), and a DPF operating unit (160). The storage unit stores the driving information which is detected by the driving information detection unit by classifying the driving information based on each cycle. The driving pattern extracting unit extracts a driving pattern by using the multiple stored cyclic travel information. The time setup unit sets up a first operation time of the DPF according to the extracted driving patterns. The control unit outputs a control signal for the operation of the DPF when the set-up first operation time comes. The DPF operating unit operates the DPF according to the control signal which is output from the control unit.

    摘要： PURPOSE: A system and a method for forcibly regenerating the DPF(Diesel Particulate Filter) of construction machines having hydraulic pumps are provided to burn fine dust inside the DPF by exothermic-reaction between high temperature exhaust gas and DOC. CONSTITUTION: A system and a method for forcibly regenerating the DPF(Diesel Particulate Filter) of construction machines having hydraulic pumps comprises a diesel engine(20), a hydraulic system, a diesel particulate filter, and a DPF regenerating unit. The hydraulic pumps are electric hydraulic pumps, which adjust the discharged flow rate by controlling current in a state that the hydraulic system is sealed. Non-working loads are generated while the discharged flow rate of the electric hydraulic pump increases without driving working machines in a state that the hydraulic system is opened. The temperature of exhaust gas increases as the heat generation rate of the diesel engine increases.

    摘要： PURPOSE: An exhaust gas post-processing system and a control method thereof are provided to prevent abnormal regeneration of a diesel particulate filter during idle state of a vehicle. CONSTITUTION: A control method of an exhaust gas post-processing system comprises following steps. A diesel particulate filter is regenerated by post injection in order to remove collected particulates. The first inlet temperature of the diesel particulate filter is sensed during the regeneration of the diesel particulate filter. The first inner temperature of the diesel particulate filter saved as data is selected according to driving conditions. Whether the first inner temperature and the first inlet temperature cross each other or not is determined. According to engine RPM and the operation of an accelerator pedal, whether the vehicle is in idle state or not is determined. If the first inner temperature and the first inlet temperature cross each other and the vehicle is in idle state, the abnormal regeneration of the diesel particulate filter is suppressed by the control of the oxygen content and exhaust flow rate included in exhaust gas.

    摘要： PURPOSE: An exhaust gas post-processing system and a control method thereof are provided to prevent damage and improve durability by reproducing a diesel particle filter according to the amount of consumed fuel or travelling distance. CONSTITUTION: A control method of an exhaust gas post-processing system comprises followings. The primary differential pressure of the front and rear ends of a diesel particle filter collecting particles included in the exhaust gas is sensed. The amount of the collected particles is sensed according to the first differential pressure. First slope on the amount of the collected particles according to the amount of consumed fuel or travelling distance is sensed. When the first slope is higher than a fixed first value, the diesel particle filter is reproduced using the setup amount of consumed fuel or the setup travelling distance as a cycle.
