Pilot control hydraulic system 5 is stated to automatically cut off；
When manually regeneration function is cancelled in selection, control the engine controller 3 to close and enable the granule capturing
Device 4, engine speed recovers normal, and pilot control turn on automatically.
Thus, the Exhaust Control of Engine device can select to carry out according to automatic mode or manual mode according to user
Discharge Regeneration control；When in automatic mode, the Exhaust Control of Engine device 2 reaches fixed in engine operating duration
During cycle time, the pilot control hydraulic system 5 is cut off, and the engine particle is started by engine controller 3 and caught
Storage 4 performs discharge regeneration, while engine keeps discharging the original working speed before regeneration starts；When in manual mode
When, Exhaust Control of Engine device 2 regenerates according to startup discharge is manually selected, while cuts off the pilot control hydraulic system 5,
And when making the execution of the engine grain catcher 4 discharge regeneration, engine is by default fixed rotating speed work set in advance.From
And cause：Firstth, the utility model can enable regeneration function according to operating mode and customer requirement, can voluntarily select automatic-discharging
Regeneration control mode or manual drain Regeneration control mode.Secondth, the utility model controls engine when enabling regeneration function
Controller cuts off pilot operated system, ensure that hydraulic construction machine can not carry out other operational motions, i.e., by pilot operated system
System and grain catcher are locked mutually, and regeneration function is switched off guide's hydraulic pressure when starting, and improves processing safety, also carries
High engine carries grain catcher regeneration function efficiency, and discharge is more environmentally friendly, and control mode is more safe and reliable, and this practicality is newly
Type emission control system is cost-effective.3rd, the utility model Exhaust Control of Engine device be desirably integrated into electrical system must
Must other electric devices in (such as in controller or engineering machinery managing apparatus with control function), only need to be to integrated
The electric device of the function carries out simple design and can be achieved with, using also very simple and convenient.4th, the utility model is in hand
During dynamic model formula, engine is pressed default fixed rotating speed and worked, and the default fixed rotating speed is more than rated speed, can further carry
Operating efficiency during high engine regeneration.
