Embodiment
Shown in please refer to the drawing 1, the utility model discloses a kind of urea injection system 100, and it can be applied in the vent gas treatment of motor 200.Described urea injection system 100 comprises urea tank 1, the sensor integrated device 2 be connected with described urea tank 1, the filter 3 being connected to described sensor integrated device 2 downstream, the fluid delivery system 4 in order to outwards to be extracted out by the urea liquid in described urea tank 1, the common rail 5 be connected with described fluid delivery system 4 and the nozzle 6 be connected with described common rail 5.Described fluid delivery system 4 comprises the pump 42 of extracted urea solution from described urea tank 1 and the controller 41 in order to control described urea injection system 100.In the illustrated mode of execution of the utility model, described controller 41 is arranged in described fluid delivery system 4, and certainly, in other embodiments, described controller 41 also can be arranged on other places.
Described motor 200 is that power is generally more than the high output diesel engine of 500 kilowatts.Correspondingly, can be understood as the utility model and relate to a kind of common rail 5 be applied in high output diesel engine.Because the power of described motor 200 is comparatively large, in order to realize good vent gas treatment, in the illustrated mode of execution of the utility model, described nozzle 6 has multiple.Under the control of described controller 41, described nozzle 6 in order to spray urea liquid in outlet pipe 201.Urea liquid after atomization is broken down into ammonia in described outlet pipe 201, and described ammonia can react with the oxynitrides in motor exhaust, thus reduces the discharge of oxynitrides.In view of the principle of this tail gas disposal technique is known described those skilled in the art, the utility model does not repeat them here.
Shown in please refer to the drawing 2 to Fig. 8, described common rail 5 is in order to regulate the pressure in urea injection system.Particularly, described common rail 5 inlet union 53 that comprises housing 50, be arranged on pressure-detecting device 51 on described housing 50 and pressure regulator 52, be connected with described fluid conveying device 4 by high pressure pipe line and the outlet connection 54 that is connected with described urea tank 1 by reflux line 300.
Shown in please refer to the drawing 6, described housing 50 is roughly in cuboid, and it comprises the first end face 501, second end face 502, the 3rd end face 503, the 4th end face 504, front 505 and the back side 506 with described vis-a-vis.Wherein, described first end face 501 is oppositely arranged with described second end face 502; Described 3rd end face 503 and the 4th end face 504 are oppositely arranged; Described front 505 is all vertical with described first end face 501, second end face 502, the 3rd end face 503 and the 4th end face 504.Shown in please refer to the drawing 4, four corners in described front 505 all have mounting hole 5051.Shown in please refer to the drawing 8 and Fig. 2, the described back side 506 is provided with mounting groove 5061 and is positioned at a pair mounting plate 5062 of described mounting groove 5061 both sides.Described common rail 5 is also provided with the screw 5052 with described mounting hole 5051 phase snap close, described common rail 5 to be fixed on described mounting plate 5062.Described inlet union 53 is installed on described first end face 501 and/or described second end face 502 with described outlet connection 54.In the illustrated mode of execution of the utility model, described inlet union 53 is installed on described first end face 501 with described outlet connection 54.Described second end face 502 is provided with tapped hole 5021, and in the illustrated mode of execution of the utility model, described pressure-detecting device 51 is pressure transducer, and it to be installed on described second end face 502 and to be communicated with described inlet passage 531.In the illustrated mode of execution of the utility model, described pressure regulator 52 is pressure controlled valve, and it to be installed in described mounting groove 5061 and between described mounting plate 5062.Setting like this, described mounting plate 5062 can play a protective role to described pressure controlled valve.Functionally, described pressure controlled valve is connected between described inlet passage 531 and described outlet passage 541, and described inlet passage 531 can be communicated with described outlet passage 541 or block by described pressure controlled valve.Such as, when the pressure that described pressure transducer detects in described inlet passage 531 is greater than setting value, described pressure controlled valve is opened by described controller 41, thus realizes decompression function.
Shown in please refer to the drawing 6, be very different in common rail 5 of the present utility model from existing fuel-injected common rail.First, through a large amount of data analyses, the utility model is applied in the pressure that bears required for the common rail 5 in urea injection system much smaller than fuel-injected common rail.Based on this analysis, the rectangular housing 50 that the utility model discloses possesses good processability.What is more important, this is that the scheme be integrated in described common rail 5 provides feasibility by outlet passage 541.Certainly, in the illustrated mode of execution of the utility model, the diameter of described inlet passage 531 is greater than the diameter of described outlet passage 541.The reason of this design is, by scientific analysis, finds that described inlet passage 531 needs the pressure born also to be different from described outlet passage 541.
