Description
Technical field
The invention belongs to motor-vehicle tail-gas to post-process catalysis and purification technology field, and in particular to a kind of adjusting exhaust gas shunt volume
Device and method.
Background technique
Currently, the upgrading with emission regulation gradually, in diesel car tail gas refining field, using the vehicle of SCR technology route
It rises year by year.And traditional liquid used urea SCR system is faced with urea low temperature crystallization, urea nozzle easily blocks, urea coking material
The problems such as SCR postprocessor are blocked, these all seriously affect the usage experience of user, increase use and maintenance cost,
Negative impact is also produced to main engine plants simultaneously.And the SSCR system based on solid ammonia storage material can be fundamentally effective
It solves the above problems.
The on-board ammonia source material of solid form during the work time, needs to heat ammonia-storing material, and solid stores up ammonia material
Material reaches the release that certain temperature realizes ammonia.Currently, there are mainly three types of the heating methods that can be provided on vehicle, one is
It is heated using engine exhaust tail gas, one is using engine coolant to be heated, then having is exactly to use electric heating
Mode.Tail gas heating, which has, in these three modes takes heat convenient, and heat is in liberal supply, improves the advantages such as engine thermal efficiency.
Therefore, it is the selection of economic and reliable that solid ammonia storage device, which uses engine exhaust waste heat as heat source,.But in practical practical process
In, the required heat of solid ammonia storage device be it is certain, and the heat of waste gas residual heat be it is much superfluous, ammonia storage device can be given
Security risk is brought, therefore, suitable extraction flow controller is selected just to be particularly important.
Chinese patent 103711966A discloses a kind of flow rate control valve structure of automatic adjustment, including center valve body, in
Heart valve body bracket, valve shell, spring, inlet end, exhaust end；Wherein: the connection of the left end of inlet end and valve shell, exhaust end
It is connect with the right end of valve shell, center valve body is mounted on inside valve shell by centre valve body support frame and spring；Centre valve
Between body and the inner wall of valve shell, cyclic annular choke zone is formed.Chinese patent 105179071A is disclosed by a kind of high-temperature gas
Through-current capacity regulating mechanism, when engine speed is higher, swivel plate is rotated clockwise, and bypass pipe necking rate becomes larger, and is put before turbine
Gas is more；When the engine speed is lower, swivel plate rotates counterclockwise, and bypass pipe necking rate becomes smaller, and deflates before turbine less.In
State patent 103133156A discloses a kind of exhaust gas recirculation quantity regulating device, for by a part of exhaust gas from internal combustion engine back into
The exhaust gas recirculation equipment of tracheae.But not only structure is complicated for device mentioned by above three patent, after also improving the whole series
The cost of reason system is not particularly suited for as the control device adjusted for solid ammonia storage device exhaust gas flow.
Summary of the invention
The object of the invention is that in view of the above shortcomings of the prior art, providing a kind of dress for adjusting exhaust gas shunt volume
It sets, the automatic adjustment to extraction flow can be realized according to delivery temperature.Another object of the present invention is to provide a kind of adjust to give up
The method of gas shunt volume.The exhaust pipe of engine or the escape pipe of SCR postprocessor are passed through a T-type tee tube by the present invention
It is divided into a and b two-way, thermo bimetal's valve block that warpage can be carried out according to delivery temperature is installed at line portals wherein all the way,
The degree of thermo bimetal's valve block warpage is different, at tube outlet can the sectional area size of outlet can also change correspondingly, i.e., with row
The raising of temperature degree, sectional area become larger, and can flow out tolerance and increase, and delivery temperature reduces, and sectional area becomes smaller, the tolerance drop that can be flowed out
It is low.And the throughput of another way is then inversely proportional with the height of delivery temperature.
