Abstract
An exhaust gas aftertreatment system (10) for a vehicle having an engine (14) includes a fluid passageway (20) extending from the engine to an ambient (18) for fluidly communicating exhaust gas (F). A diesel particulate filter (24) is disposed on the fluid passageway (20) downstream of the engine (14). At least one exhaust throttle valve (30A-30D) is located downstream of the engine (14) on the fluid passageway (20). When the exhaust throttle valve (30A-30D) is actuated, the valve obstructs the flow of exhaust gas (F) and increases the temperature of the exhaust gas. The heated exhaust gas (F) causes regeneration at the diesel particulate filter (24).

Embodiment
Referring to Fig. 1-3, the exhausted gas post-processing system that is used for vehicle is always referred to by reference character 10, and has exhaust piping assembly 12, and this exhaust piping assembly extends to outlet 16 from motor 14, for example discharged to the outlet of environment 18.Exhaust piping assembly 12 forms fluid passage 20, and this fluid passage 20 is used for making waste gas F flow to environment 18 from motor 14.The downstream direction of waste gas streams F is to outlet 16 from motor 14.
The first portion 22 of exhaust piping assembly 12 extends to diesel particulate filter (DPF) 24 from motor 14.DPF24 is the filter that is made of the material of anti-the thermal extremes.DPF24 captures and keeps being discharged into the particulate matter of carrying secretly in the waste gas in the exhausted gas post-processing system 10.DPF24 periodically regenerates, with the backpressure rising that limits exhausted gas post-processing system 10 and the efficient that keeps motor 14.The second portion 26 of exhaust piping assembly 12 extends to outlet 16 from DPF24.Exhaust manifold 28 can be positioned at the upstream of the first portion 22 of exhaust piping assembly 12.Other parts can be arranged on the after-treatment system 10, and for example diesel oil oxidation catalyst converter (not shown) can be positioned at the DPF24 upstream.
Referring now to Fig. 1,, at least one exhaust gas throttle valve 30A be arranged to fluid passage 20 on motor 14 fluids be communicated with and be arranged on the downstream of motor 14.When exhaust gas throttle valve 30A activated, exhaust gas throttle valve 30A hindered waste gas F and flows through fluid passage 20.
Exhaust gas throttle valve 30A can be fly valve 32A, yet the valve of other type also is possible.Fly valve 32A utilizes actuator 34A to regulate waste gas streams F by fluid passage 20, this actuator 34A turns to arbitrary position between open position or closed position or this two positions with fly valve 32A, this open position valve 32A is parallel to waste gas streams F, and closed position valve 32A is perpendicular to waste gas streams F.Fly valve 32A hinders waste gas F and flows through fluid passage 20.At parallel open position, the hole at fly valve 32A place has the largest hole open area that produces the minimal flow obstruction, and in vertical closed position, the hole at fly valve place has the minimum orifice area that produces the maximum fluidity obstruction.In vertical closed position, exhaust gas throttle valve 30A can prevent from being communicated with by the fluid of the second portion 26 of exhaust piping assembly 12 hermetically.
Actuator 34A can be by hydraulic pressure or electric driving.Engine control module (ECM) 36 is according to the pressure and temperature condition in the after-treatment system 10, control exhaust gas throttle valve 30A by actuator 34A.During pressure transducer transmits after-treatment system 10 to ECM36, for example in pressure and the transmission back pressure at exhaust manifold 28 or DPF24 place.Back pressure can be for example variation of the pressure between two positions of DPF24 upstream and downstream of after-treatment system 10.
On the back pressure of predetermined value, DPF can be stopped up by particulate matter under the predetermined temperature of exhaust manifold 28 or DPF24 or in the after-treatment system 10.When sensing the exhaust back-pressure of predetermined value by PFE Exhaust Pressure Transducer 40, perhaps at the DPF24 place, when sensing predetermined temperature at exhaust manifold 28 places or in any position of after-treatment system 10, this exhaust back-pressure or predetermined temperature can be sent to ECM36, activate exhaust gas throttle valve 30A.Pressure and temperature numerical value is sent to ECM36, and ECM order actuating exhaust gas throttle valve 30A partially or fully closes.In one embodiment, fly valve 32A closes about 80-90% of fluid passage 30 mesopores.
Exhaust gas throttle valve 30A opens until activated by actuator 34A.When exhaust gas throttle valve 30A partially or even wholly closed, the waste gas F in the after-treatment system 10 of exhaust gas throttle valve upstream was compressed, caused the temperature of waste gas F to raise.In addition, the resistance of piston 42 need to inject the setting value that cylinder 44 satisfies motor 14 with more substantial fuel.Additional fuel is infused in and produces additional heat energy among the waste gas F.The rising temperature of the waste gas F of exhaust gas throttle valve 30A upstream passes to DPF24 when waste gas flow to DPF downstream.Provide sufficient heat to come in DPF24 place startup regeneration (soot oxidation) through the waste gas F of heating.
Referring now to Fig. 2,, exhaust gas throttle valve 30B and actuator 34B are positioned on the second portion 26 of exhaust piping assembly at the alternative site place in DPF24 downstream.Exhaust gas throttle valve 30B is the equipment identical with the equipment of reference exhaust gas throttle valve 30A description, operate in the mode identical with exhaust gas throttle valve 30A, and throttle valve 30B identical with exhaust gas throttle valve 30A is the part of after-treatment system 10.The difference of exhaust gas throttle valve 30A and 30B is to be positioned at the position on the after-treatment system 10.
When activating exhaust gas throttle valve 30B, the temperature of waste gas F is high in the downstream side at the upstream side ratio of fly valve 32B.In after-treatment system shown in Figure 2, DPF24 stands the waste gas F of higher temperature, because DPF also is positioned at the upstream of exhaust gas throttle valve 30B.Yet DPF24 also stands the higher temperature of exhaust gas throttle valve 30B upstream.
Referring now to Fig. 3,, exhausted gas post-processing system 10 also can comprise two exhaust gas throttle valve 30C, 30D with two actuator 34C, 34D.Exhaust gas throttle valve 30C, 30D are the identical equipment of equipment of describing with reference exhaust gas throttle valve 30A and 30B, and they operate in the mode identical with 30B with exhaust gas throttle valve 30A, and identical with 30B with exhaust gas throttle valve 30A be the part of after-treatment system 10.The difference of exhaust gas throttle valve 30A-30D is to be positioned at the position on the after-treatment system 10.
On fluid passage 20, the first exhaust gas throttle valve 30C is arranged in the upstream and is communicated with the DPF24 fluid, and is communicated with motor 14 and exhaust manifold 28 fluids in the downstream.The second exhaust gas throttle valve 30D 20 is arranged in the downstream and is communicated with the DPF24 fluid in the fluid passage.Be similar to exhaust gas throttle valve 30A and 30B, exhaust gas throttle valve 30C and 30D can be fly valve 32C, 32D, yet the valve of other type also is possible.
