Detailed description of the invention
Fig. 1 applies to the structure chart of the modular hydrogen EGR of fuel cell car.
As it can be seen, hydrogen EGR 10 includes: the residual gas being recycled to fuel cell pack 2 is pressurizeed, and with
Supplied by hydrogen gas tank 1, flow through the injector module 11 mixed mutually with hydrogen of hydrogen line 3；And, divide in fuel cell pack 2 rear end
, and be connected with flow valve 4 rear end controlling to be supplied amounts of hydrogen by hydrogen gas tank 1, form residual gas flow path again
Circular route 13.
Above-mentioned injector module 11 is arranged on the rear end controlling to be supplied the flow valve 4 of amounts of hydrogen by hydrogen gas tank 1.
Above-mentioned injector module 11 is pressurizeed by by nozzle and diffuser structure, and to the high pressure of hydrogen gas tank 1 supply
(10bar) hydrogen injection, improves the injector 11a of pressure hydrogen pressure；High-speed motor is utilized to improve the pressure hydrogen of rotary blade
The air blast 11b of pressure；Between the outlet and entrance of injector 11a, the inside of closed-loop path is formed after air blast 11b is installed
The line of return 12 forms.
The suction of above-mentioned air blast 11b is arranged to by the present embodiment be enough to, by flowing out from injector 11a outlet, flow into combustion
The air-flow of material battery pile 2 is converted into the degree of the internal line of return 12.
But, after the above-mentioned internal line of return 12 sets up closure valve, injector 11a outlet both can with re-circulation line 13 even
Logical, it is also possible to connect with hydrogen line 3.
Above-mentioned closure valve is by controller control.

Region extends to middle load (middle flow) region, and the criterion in centering load (middle flow) region is that air blast 11b is to residue
Gas fully pressurizes and returns the starting point of performance.
It practice, the standard in centering load (middle flow) region changes along with the change of air blast 11b specification.
Meanwhile, Fig. 2 (b) is the running status in hydrogen EGR high load capacity (high flow capacity) region.
If as it can be seen, hydrogen EGR 10 is at high load capacity (high flow capacity) area operation, from fuel cell pack 2 rear end
The residual gas flowed out supplies the porch to injector module 11 by re-circulation line 13.
Supply will flow into injector 11a to the residual gas of above-mentioned injector module 11 porch, flow into injector 11a's
Residual gas flows out from exit after injector 11a internal pressurization.
Now, air blast 11b does not runs, and the gas-pressurized thus flowed out from injector 11a exit is supplied by hydrogen line 3
To fuel cell pack 2.
If the internal line of return 12 is equipped with closure valve, above-mentioned closure valve can be cut off the internal line of return 12 and open hydrogen line 3, turns
Shift to injector 11a and export the state being interconnected with hydrogen line 3, fuel cell pack 2.
This is because not in the case of air blast (11b) pressurizes, remain to reality only by injector (11a) pressurization
Existing pressurizing performance giving full play in high load capacity (high flow capacity) region.
Even if especially it is possible to being solved the air blast run to greatest extent in high load capacity (high flow capacity) region by These characteristics
Machine 11b can not meet recirculating mass, but causes the shortcoming problem recycling the serial mixed power mode of degraded performance；
And reduction consumption power can also be run by stopping air blast 11b.
As it has been described above, the hydrogen EGR 10 that the present embodiment relates to, by injector 11a branch (to from fuel cell
The injector of the residual gas pressurization that heap 2 recycles) and reconnect injector 11a, the inside being simultaneously equipped with air blast 11b is returned
Injector module 11 that loop line 12 is formed, the re-circulation line 13 being connected to injector module 11 from fuel cell pack 2 rear end form.
During operation, if underload (low discharge) region can carry out twice pressurized treatments by injector 11a and air blast 11b, as
Fruit is to pressurize merely with injector 11a in high load capacity (high flow capacity) region, had both reduced air blast and has run the power consumption caused, also
Decrease noise, especially by the modularization of injector 11a Yu air blast 11b, decrease amount of parts, and achieve cloth
