Description
Technical field
The utility model is related to the technical fields of GPF grain catchers, and low regeneration temperature can be achieved more particularly to one kind
Completely new GPF granule capturing monitoring systems.
Background technology
There are strict requirements to exhaust particulate in six B/ Europe of state, six D emission regulations, traditional after-treatment device can not be filtered
Carbon particle in removing exhaust gas, so GPF grain catchers are widely used in the vehicle discharge exploitation of six B/ Europe of state, six D, but
Due to arrangement etc., GPF positions are often in lower channel position, and distant with engine, particulate matter is low in GPF
In the case of oxygen concentration, particulate regeneration is extremely difficult to the more demanding of temperature, GPF and engine hypertelorism, temperature
Regeneration requirements.
Utility model content
The utility model is in view of the problems of the existing technology and insufficient, provides a kind of GPF of novel low regeneration temperature
Granule capturing monitors system, and realizing increases oxygen concentration in GPF, can effectively reduce regeneration temperature.
The utility model is to solve above-mentioned technical problem by following technical proposals：
The utility model provides a kind of GPF granule capturings monitoring system of low regeneration temperature, and feature is, including one
GPF grain catchers, a venturi system, a by-passing valve and a check valve, the check valve be set to booster after, before charge air cooler
Pipeline on, which connects with the venturi system pipeline, which connects with the by-passing valve pipeline, this article mound
In system and the by-passing valve connect with the GPF grain catcher pipelines；
GPF granule capturings monitoring system further includes one for detecting the pressure difference sensing of the pressure of the GPF grain catchers
Device and one is used to receive pressure value and send a by-passing valve shutdown signal when the pressure value reaches a setting value to the by-passing valve
Controller, which connect with the inlet and outlet of the GPF grain catchers, the differential pressure pickup and the by-passing valve
It is connect with the controller.
Preferably, the controller is ECU (electronic control unit).
On the basis of common knowledge of the art, above-mentioned each optimum condition, can arbitrarily combine to get the utility model respectively compared with
Good example.
The positive effect of the utility model is：
The utility model increases a set of making-up air device on the basis of traditional GPF granule capturings system, by booster
Afterwards, the high temperature and pressure fresh air before charge air cooler introduces GPF front ends, so as to fulfill the enriching of oxygen concentration in GPF, reduces regeneration
Temperature.
Description of the drawings
Fig. 1 is that the GPF granule capturings of the utility model preferred embodiment monitor the schematic diagram of system.
Specific embodiment
Purpose, technical scheme and advantage to make the utility model embodiment are clearer, new below in conjunction with this practicality
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, those of ordinary skill in the art's all other embodiments obtained under the premise of creative work is not made all belong to
In the range of the utility model protection.
As shown in Figure 1, the GPF granule capturings the present embodiment provides a kind of low regeneration temperature monitor system, including a GPF
Grain catcher 1, a venturi system 2, a by-passing valve 3, a check valve 4, a differential pressure pickup Δ P and an ECU 5, this is unidirectional
Valve 4 be set to booster after, on the pipeline before charge air cooler, which connects with 2 pipeline of venturi system, the venturi
System 2 is connected with 3 pipeline of by-passing valve, and the venturi system 2 and the by-passing valve 3 connect with 1 pipeline of GPF grain catchers
It connects, which connect with the inlet and outlet of the GPF grain catchers 1, the differential pressure pickup Δ P and the bypass
Valve 3 is connect with the ECU 5.
The present embodiment increases a set of making-up air device on the basis of traditional GPF granule capturings system.By after booster,
High temperature and pressure fresh air before charge air cooler introduces GPF front ends, so as to fulfill the enriching of oxygen concentration in GPF, reduces regeneration temperature
Degree.Meanwhile by venturi system, it is low that the part that the swiftly flowing gas in venturi system generates is bypassed using exhaust pipe
Pressure before gas is drawn to GPF from the pipeline before charge air cooler, and inhibits exhaust gas recirculation using check valve 4.
In the control module, the pressure of GPF grain catchers 1 is detected by the differential pressure pickup Δ P before and after GPF, so as to
Judge carbon particle accumulation, when carbon particle reaches constant weight, signal is sent out by ECU 5, control by-passing valve 3 is closed, literary mound
In system 2 start to work, be evacuated from air inlet pipe, increase oxygen concentration, realize low-temp recovery, GPF grain catchers 1 are front and rear to press
Power restores normal, and by-passing valve 3 is opened, and venturi system 2 is stopped, normal exhaust, so recycles.
Although the foregoing describe specific embodiment of the present utility model, it will be appreciated by those of skill in the art that
These are merely examples, and the scope of protection of the utility model is defined by the appended claims.Those skilled in the art
Member can make these embodiments numerous variations or repair under the premise of the principle and essence without departing substantially from the utility model
Change, but these change and modification each fall within the scope of protection of the utility model.
