Abstract
The utility model relates to an exhaust-gas turbocharger, comprising a moving turbo-disk. Turbo-bodies on both sides of the turbo-disk are respectively assembled with two static turbo-disks to compose a compressor and an exhaust-gas expander. The utility model has the advantages that the compression ratio is hardly changed with flow variation, surging and flow blockage do not occur; the flow variation is only relevant with rotating speed.
Description
The utility model relates to a kind of volume type exhaust eddy type pressurized machine.
The development of modern science technology promotes internal combustion engine development to new level, and correspondingly, the supercharging of internal combustion engine technology has also had great development.In recent years, energy-conservation more and more important, fuel consumption falls in an urgent demand significantly; Adiabatic engine also adopts the waste gas pressurization system to utilize exhaust energy, and all these impels the supercharging of internal combustion engine technology to develop rapidly.The supercharging of internal combustion engine technology promptly expands to internal-combustion engine of middle low power, to be applicable to car combustion engine and engineering machinery internal combustion engine just from the heavy duty scope at present.
In the supercharging of internal combustion engine technology, exhaust-gas turbocharger is used comparatively extensive.Exhaust-gas turbocharger is to promote turbo-expander with the waste gas of internal-combustion engine to drive gas compressor, reaching pressurized air, and the purpose of air intake pressurized, such pressurized machine adopts one-stage centrifugal formula gas compressor and single stage turbine decompressor more.Diesel engine and exhaust-gas turbocharger can occur when incorrect supporting: diesel engine does not reach the pressurized effect of expection; The pressurized machine job insecurity, surge appears in gas compressor; Exhaust gas turbine occur flow blockage (" supercharging of internal combustion engine technology ", Shen Quanbian, Chinese railway industry publishing house, November nineteen ninety version).
Since the eighties, convolute-hydrodynamic mechanics has obtained Application and Development, and scroll machine has the efficient height, and working medium is leaked hardly, and air-breathing and exhaust are not contacted directly, and valve need be set, the reliability height, and amount of parts is few, and characteristics such as can run up.
The purpose of this utility model is at the advantage of scroll machine and the deficiency of exhaust-gas turbocharger, a kind of waste gas eddy type pressurized machine is proposed, it is a kind of displacement fluid mechanism, comprise an eddy type gas compressor and a scroll expansion machine, has pressure ratio not with changes in flow rate, gas compressor surge can not occur, and the variation of flow is the rpm-dependent variation characteristics only.
Accompanying drawing is a structure principle chart of the present utility model.
Below in conjunction with accompanying drawing structural principle of the present utility model and working principle are done detailed explanation.
With reference to accompanying drawing, the utility model comprises a moving scroll 5, the both sides vortex body of moving scroll 5 is formed the active chamber of gas compressor and waste gas exapnsion machine respectively with fixed scroll 1 and 4 configurations, the center cavity a of fixed scroll 1 is connected with outlet pipe 2, the air aspiration cavity b of fixed scroll 1 is connected with suction tude 3, the center cavity c of fixed scroll 4 is connected with waste gas inlet pipe 6, and the exhaust cavity d of fixed scroll 4 is connected with outlet pipe 7.Dispose slide block 8 on the fixed scroll 4, slide block 8 matches with pin 9, pin 9 and moving scroll 5 Joints, and fixed scroll 4 also disposes crank pin 10, and crank pin 10 matches with moving scroll 5.
Working principle of the present utility model is: the exhaust that suction tude 6 sucks from internal-combustion engine vent-pipe, enter center cavity c, and outer gradually moving behind the formation enclosed volume, expansion working, exhaust gas pressure and temperature constantly reduce, and at last by exhaust cavity d, enter atmosphere through outlet pipe 7.Suction tude 3 sucks fresh charges, forms enclosed volume, and moves gradually, and power pressure constantly raises, reach predetermined pressure ratio after, enter the induction chamber of internal-combustion engine through outlet pipe 2 by center cavity a.
The merit that useless guide expansion is done equals the merit of gas compressor pressurized gas, and stable operation.
The revolution translational motion of moving scroll 5 is by two crank pins, or two slide blocks, or a crank pin and a slide block are realized.Crank pin 10 can be realized by sliding bearing or rolling bearing movingly with moving scroll 5 and fixed scroll 4.
