摘要： An exhaust gas purification system for an engineering machine is provided which is capable of avoiding decreases in working efficiency during regeneration control by burning off a deposit of particulate matter from a filter (11) efficiently during a work pause time of the engineering machine. An operating section (17) of a display monitor (16) is assigned a function that sets a work pause time for a hydraulic excavator, and has a work pause switch (13) that notifies to a vehicle body control unit (21) that the hydraulic excavator has entered a work pause state. Upon receiving the notice of the fact that the hydraulic excavator has entered the work pause state, the vehicle body control unit (21) calculates the time required for a regenerating device to burn off the current amount of particulate matter deposited on the filter (11), and when the fact that the engineering machine has entered the work pause state is notified and the calculated time is longer than the preset work pause time, then activates a regeneration controller (4a) of an engine control unit (4), and switches a solenoid control valve (15) to a closed position during the preset work pause time.

摘要： Provided is a working machine that is equipped with a manual regeneration system that can simply be controlled and enables warm-up in a short time.
After a manual regeneration switch (22) is shifted to an ON-position and when cooling water temperature is lower than flame-out prevention temperature T1, a load control section (66) keeps at least one of the revolution speed (N) of an engine (1), the displacement volume (q) and discharge pressure (P) of a hydraulic pressure pump (11) at a corresponding first target value (N1, q1, or P1). In addition, after the manual regeneration switch is shifted to the ON-position and when the cooling water temperature is equal to or higher than T1, the load control section keeps at least one of the revolution speed (N) of the engine, the displacement volume (q) and discharge pressure (P) of the hydraulic pressure pump at a corresponding second target value (N2, q2, or P2). On the other hand, a regeneration control section (67) starts the compulsory regeneration after the manual regeneration switch (22) has been shifted to the ON-position and when the cooling water temperature is equal to or higher than T1.

摘要： During automatic regeneration, the gate lock lever (5) may be in a locked state and work may be not performed. In such a case, when exhaust gas temperature is lower than the threshold value, temperature-rising assistance is started. The minimum engine output PS1 (pump discharge pressure P1 and pump discharge amount Q1) is brought to engine output PS2 (pump discharge pressure P2 and pump discharge amount Q2). In this way, a hydraulic load is applied to an engine to thereby increase exhaust gas temperature. In a case where the work is resumed during the regeneration, when an operator pulls down the gate lock lever (5) to the first position A, the engine output PS2 is returned to the minimum engine output PS1 (pump discharge pressure P1 and pump discharge amount Q1). Thus, the temperature-rising assistance is stopped. Even if the temperature-rising assistance is stopped, the automatic regeneration is continued.
