Detailed description of the invention
It is better understood from the utility model for the ease of those skilled in the art, below in conjunction with the accompanying drawings with specific embodiment to this reality
Being described in further details with novel, following is only exemplary not limit protection domain of the present utility model.
As it is shown in figure 1, the utility model discloses a kind of heavy-duty car dpf regeneration control system, including the 5th, engine increases
Depressor the 1st, charge air cooler the 2nd, intake-air throttle valve the 3rd, HC injection apparatus the 6th, DOC the 8th, DPF the 10th, crankshaft rotational speed sensor and being arranged at is driven
Sailing the regeneration request switch of indoor, the compressor blade of booster 1 is arranged in engine air inlet tube, wormwheel blade is arranged at and sends out
It in motivation blast pipe, after charge air cooler 2 and intake-air throttle valve 3 are positioned at booster and is set in turn in air inlet pipe along airintake direction
On, HC injection apparatus the 6th, DOC 8 and DPF 10 is set in turn on blast pipe along discharge directions, HC injection apparatus 6 and DOC 8 it
Between be provided with DOC upstream temperature sensor 7, be provided with DPF upstream temperature sensor 9 between DOC 8 and DPF 10, air inlet pipe with
It is provided with EGR valve 4 between blast pipe；Described crankshaft rotational speed sensor, regeneration request switch, intake-air throttle valve the 3rd, EGR valve the 4th, HC
Injection apparatus the 6th, DOC upstream temperature sensor 7 and DPF upstream temperature sensor 9 all electrically connects with the ECU of vehicle.When activate again
During raw request switch, ECU sprays advance angle, distributive value and main jet advance angle and intake-air throttle valve 3 and EGR valve 4 after adjusting
Aperture, control DOC 8 upstream temperature；By HC injection apparatus 6, the upstream temperature of control DPF 10, to complete regeneration.
The specific works process of the utility model heavy-duty car dpf regeneration control system is as follows:
1st, the temperature rise period: vehicle is parked in a certain place, start engine, press regeneration request switch, then ECU control is started
Machine rotating speed maintains a certain higher rotation speed, adjusts the corresponding rear spray advance angle of this rotating speed, distributive value and main jet advance angle, same to time control
(general EGR valve 4 completely closes the aperture of intake-air throttle valve 3 processed and EGR valve 4, and i.e. zero exhausted air quantity enters engine air inlet tube, anti-
Only EGT runs off；Intake-air throttle valve 3 closes more than 50%, i.e. closes a part of FAI Fresh Air Intake amount, to play insulation
Effect), make DOC 8 upstream temperature temperature control in 350 DEG C-400 DEG C, ECU internal timer is when pressing regeneration request switch
Start timing, this stage duration T1.
2nd, regeneration stage: after the temperature rise period terminates, ECU control engine speed maintains a certain higher rotation speed, and HC sprays
Device 6 sprays into diesel oil in the exhaust pipe of engine, improves temperature through DOC 8, makes carbon granule in DPF 10 burn (in order to ensure
The abundant burning of carbon granule, DPF upstream temperature controls at about 600 DEG C).ECU internal timer is opened after the temperature rise period terminates
Beginning timing, this stage duration T2, described T2 can be configured according to road conditions before regeneration intervals duration twice and regeneration etc..
3rd, temperature-fall period: after regeneration stage terminates, ECU control engine returns to idling, controls intake-air throttle valve 3 complete simultaneously
Opening, i.e. maximum FAI Fresh Air Intake amount enters engine air inlet tube, and ECU detects the upstream temperature of DOC 8 and the upper of DPF 10
Trip temperature, when below setting value, then it is assumed that lower the temperature successfully.After lowering the temperature successfully, complete regenerative process, enter properly functioning mould
Formula.
Above only describes general principle of the present utility model and preferred embodiment, those skilled in the art can be according to above-mentioned
Many changes may be made and improves in description, and these changes and improvements should belong to protection domain of the present utility model.
