Description
Technical field
The utility model belongs to failure monitoring and the protected mode field of motor vehicle exhaustion system particulate filter, especially relates to a kind of Motor Vehicle particulate filter abating protection device.
Background technique
Atmosphere environment PM2.5 pollution problem is the environmental protection focus that current country shows great attention to, as an important emission source of PM2.5, the granular material discharged technological difficulties being automobile industry always and putting forth effort to solve of Motor Vehicle, along with current China vehicles number increases fast, how effectively to reduce the discharge quantity of particulate matter of Motor Vehicle, meet national legislation requirement, and take into account energy-conservation and environmental protection, become the day by day urgent task of needing to solve.Granular material discharged control of current employing diesel-oil vehicle particulate filter (DPF) to diesel-oil vehicle becomes a generally acknowledged effective external purification technology.And for in-cylinder direct injection (GDI) petrol engine, correlative study shows, the fine grained emission problem of GDI petrol engine can not be ignored, GDI petrol engine is also an important PM2.5 emission source, therefore with reference to the DPF technology of diesel engine, it is also an effective particulate matter external purification technology that GDI petrol engine installs additional petrol engine particulate filter (GPF).
The working principle of particulate filter, all adopt the particulate matter in filtering effect collection motor-vehicle tail-gas, along with the growth of operating time, the particulate matter that particulate filter is piled up can get more and more, and causes plugged filter exhaust back pressure to raise, and oil consumption raises, affect the normal working of motor, serious also can cause engine damage, and therefore for particulate filter, filter regeneration is the technological scheme that must consider.Regenerated way is divided into initiative regeneration and passive regeneration.Initiative regeneration refers to utilize outside energy to improve particulate filter temperature, makes particulate matter ignition.Passive regeneration refers to more than uniform temperature, and not by outside energy, some oxide in exhaust, as NO
2and O
2deng also can particulate matter voluntarily in oxidize particulate matter filter, thus realize the object of particulate regeneration.Therefore, when under certain abnormal condition, regenerative process do not carry out or out of control time, particulate matter or can constantly accumulate in the filter, causes final blocking, otherwise one may to be that regeneration is overheated cause after-treatment system to sinter to damage, thus blocking exhaust, cause engine failure, therefore, how to avoid plugged filter to cause engine failure to be focus of the present invention
Summary of the invention
In view of this, the utility model is intended to propose a kind of Motor Vehicle particulate filter abating protection device, repairs maintenance in time, avoid engine damage and discharge to exceed standard to realize Motor Vehicle.
For achieving the above object, the technical solution of the utility model is achieved in that
A kind of Motor Vehicle particulate filter abating protection device, the bypassed exhaust gas pipeline 4 comprising the particulate filter 1 be arranged in motor blowdown piping, be connected to the sensor at described particulate filter 1 two ends, be arranged in parallel with described particulate filter 1, the stopper 2 being arranged at described particulate filter 1 entrance, the bypass cock 3 being arranged at described bypassed exhaust gas pipeline 4 entrance, the control module 7 be connected with described sensor, bypass cock 3, stopper 2 and motor.
Further, described sensor comprises pressure transducer 5 and temperature transducer 6.
Further, described stopper 2 is stop valve.
Further, described bypass cock 3 is bypass valve.
Relative to prior art, a kind of Motor Vehicle particulate filter abating protection device described in the utility model has following advantage: when particulate filter occurring and regenerating abnormal or plugging fault, engine control module forces motor to enter limping pattern, simultaneously by closing stop valve, open bypass valve, avoid particulate filter to damage further or cause engine operating condition abnormal owing to being vented smooth fault, compared to conventional particles thing filter, effectively can avoid the damage of filter and the motor caused when particulate filter fault, improve the safety in utilization of particulate filter, simultaneously the utility model and engine aftertreatment system combining structure simple, cost is low, be applicable to all Motor Vehicle particulate filter forms.

Description of reference numerals:
1-particulate filter, 2-stopper, 3-bypass cock, 4-bypassed exhaust gas pipeline, 5-pressure transducer, 6-temperature transducer, 7-control module.
Embodiment
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As shown in Figure 1; a kind of Motor Vehicle particulate filter abating protection device, the bypassed exhaust gas pipeline 4 comprising the particulate filter 1 be arranged in motor blowdown piping, be connected to the sensor at described particulate filter 1 two ends, be arranged in parallel with described particulate filter 1, the stopper 2 being arranged at described particulate filter 1 entrance, the bypass cock 3 being arranged at described bypassed exhaust gas pipeline 4 entrance, the control module 7 be connected with described sensor, bypass cock 3, stopper 2 and motor.Sensor comprises pressure transducer 5 and temperature transducer 6.Stopper 2 is stop valve.Bypass cock 3 is bypass valve.
Sensor determination particulate matter load level, judges particulate filter 1 state simultaneously, and determining whether needs regeneration and failure condition; When judging that particulate filter 1 needs regeneration, start reproducer; When judging particulate filter 1 abnormal state, opening bypass cock 3 and closing stopper 2, being vented and being flowed out by bypassed exhaust gas pipeline 4, make vehicle enter limping pattern by controller.
Control module 7 is based on flow, temperature, differential pressure information determination present granule thing load level, control particulate filter 1 to regenerate, judge regeneration effect simultaneously, control bypass cock 3 is opened stopper 2 and is closed, simultaneously by information feed back to engine controller, perform limping mode command and light fault indicating lamp simultaneously.
Working procedure of the present utility model is as follows, arranges pressure transducer 5 before and after particulate filter 1, and in order to measure particulate filter 1 particulate matter load level, control module 7 judges regeneration situation and judges fault simultaneously; Temperature transducer 6 is arranged before and after particulate filter 1, before and after monitoring particulate filter 1, delivery temperature carries out Regeneration control simultaneously, if detect that two ends pressure reduction is excessive, exceed normal pressure difference limit value, or the row's of import and export temperature exceeds regular regeneration scope, control module 7 closes discharge line valve, opens exhaust by-pass valve simultaneously, makes exhaust stream through bypassed exhaust gas pipeline 4; The granular material discharged deterioration of Motor Vehicle can be caused owing to being vented the untreated air that directly enters, when triggering bypass, control module 7 is to engine controller feedback trouble signal, Engine ECU enters the limp-home mode of low-load, low emission by controlling motor, light vehicular meter warning lamp simultaneously and propose warning to driver; After regenerative process terminates, again judge particulate filter 1 state, as found, fault carries out above-mentioned measure.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
