Description
Technical field：
The present invention relates to variable-area turbocharger, is divided by International Patent Classification (IPC) (IPC) and belongs to mechanical engineering；Illumination；
Heating；Weapon；Explosion portion；Common engineering branch, fluid pressure actuator；General hydraulic technique and pneumatics big class, one
As fluid operating system；Fluid pressure actuator, such as servo motor；The Fluid pressure part group of other classes is excluded, is had
There is the servo motor of follow-up action, i.e. the wherein position of driven member big group consistent with control unit；There is reciprocating or pendulum
Dynamic formula servo motor group technique field.
Background technology：
There is variable throat turbocharger at this stage, efficiency is low；Tongue shape baffle plate variable section turbocharger, flow losses are big, adjust
Adjusting range has certain limitations, and supercharger aggregate efficiency is low；Variable nozzle ring whirlpool supercharger (VNT) range of accommodation is wide, increases in low speed
The aggregate efficiency of depressor is high, but complex structure, and material requirements is high, high cost.
Content of the invention：
1 the object of the invention：With simple structure, low cost, the full-time maximum performance of variable-area turbocharger full speed section is reached
Charging efficiency, bigger energy-saving and emission-reduction.Solved because EGT is high simultaneously, variable-area turbocharger material requirements is high-leveled and difficult to ask
Topic.
2 technical solutions：Shown in Fig. 1：Comb shape tongue piece (1) on the upside of scroll (5) by rotating shaft (4) device.Shown in Fig. 2：
Waste gas drainage (8) is divided into high-speed eddy (3) and low speed vortex (7) by comb shape tongue piece (1), and the rotating speed of turbine (2) is by high-speed eddy
(3) flow rate regulation.The throw of comb shape tongue piece (1) by waste gas drainage (8) and the pressure difference of low speed vortex (7), lead by rotating shaft (4)
Gravitation, the quality three dynamic balance of comb shape tongue piece (1) determine.During low engine speed, waste gas drainage (8) and low speed vortex (7)
Pressure difference is little, and comb shape tongue piece (1) throw is little；During high engine speeds, waste gas drainage (8) and low speed vortex (7) pressure difference are big, comb shape
Tongue piece (1) throw is big.Waste gas drainage (8) and low speed vortex (7) pressure difference adjust high-speed eddy for a range of variable
(3) sectional area implementation.
3 technique effects：The social effect that can reach of the present invention can greatly energy-saving and emission-reduction, by apparatus of the present invention
Test on certain picking-up vehicle domestic, its diesel motor is 28TC, high speed oil consumption changes the outfit before the present invention as 7 .6L/100KM, changes
It is 6 .8L/100KM after dress；City oil consumption changes the outfit before the present invention as 8 .8L/100KM, is 8L/100KM after changing the outfit.Technical requirements
Very simple, and material is common, and high exhaust temperatures have no effect on charging efficiency to the miniature deformation of material.
Description of the drawings：
Accompanying drawing provides comb shape tongue piece shunting variable section turbocharger structural representation of the present invention.
Fig. 1 is that comb shape tongue piece shunting variable section turbocharger comb shape tongue piece of the present invention faces structural representation in scroll
Figure.
Fig. 2 is comb shape tongue piece shunting variable section turbocharger side-looking internal structure schematic diagram of the present invention.
7 low speed vortex, 8 waste gas row on the downside of 6 scrolls on the upside of 1 comb shape tongue piece, 2 turbine, 3 high-speed eddy, 4 rotating shaft, 5 scroll
Flow 9 volute inlet smallest cross-sectional, 10 split point scroll flow area, 11 volute.
Specific embodiment：
In Fig. 1, if comb shape tongue piece (1) tooth with rotating shaft (4) sectional area and with the ratio of split point scroll actual internal area (10) is
K, K=181/432；If comb shape tongue piece (1) tooth gross mass (gram) is accumulated with tooth shaft section and (square millimeter) ratio is N, N=(11/
1086)；Split point scroll flow area (10) is square, if its length of side is a, comb shape tongue piece (1) tooth is hollow cylinder tooth, if
Tine length is b, b/a=8/9.
In Fig. 2, vehicle-mounted installation is vertical with wheel axis grade separation using the central axis that need to meet rotating shaft (4), on the downside of scroll
(6) aerofluxuss to 15 degree of car four-wheel axial plane angle, on the upside of scroll, (5) are symmetrical with downside (6), volute inlet minimum sectional area
(9) it is 2/3 with the ratio of split point scroll actual internal area (10).
Comb shape tongue piece of the present invention shunting variable section turbocharger device is tested on certain picking-up vehicle domestic by inventor, its
Diesel motor is 28TC. according to Actual measurement, by comb shape tongue piece (1) tooth and rotating shaft (4) sectional area and be set as 545 (square
Millimeter), split point scroll flow area (9) area is set as that 1295 (square millimeters), comb gross mass are set as 5 .5
Gram, comb length (b) is set as 31mm, and the split point scroll flow area square length of side (a) is 36mm.Test effect electromotor
Before noise is significantly lower than installation, accelerate without turbocharging slow phenomenon during engine bed speed, response is quick, high speed oil consumption changes the outfit comb
It is 7 .6L/100KM before shape tongue piece shunting variable section turbocharger, is 6 .8L/100KM after changing the outfit；City oil consumption changes the outfit
It is 8 .8L/100KM before of the invention, is 8L/100KM after changing the outfit.No matter engine temperature height does not affect charging efficiency.
