Description
Technical field
This utility model is related to turbocharger, especially a kind of turbocharger for gasoline engine.
Background technology
Turbocharger has four major advantages：1. HP, hp/litre is improved, 2. improves the discharge of electromotor, 3. provided
The function of altitude-compensation, 4. improves fuel economy；As turbocharger has four kinds of advantages above, so on home vehicle
Utilization increasingly popularize.
In order to meet market, it is badly in need of now a kind of home vehicle of the high power of low discharge capacity, turbocharger is just essential.
Utility model content
The technical problems to be solved in the utility model is：In order to solve to lack the domestic vehicle of the high power of low discharge capacity on the market
Problem, there is provided a kind of turbocharger for gasoline engine.
This utility model solves the technical scheme adopted by its technical problem：A kind of turbocharger for gasoline engine, including
The compressor being fixedly connected by armature spindle and turbine, are provided with executor at the air inlet of the compressor, described to calm the anger
Impeller cavity of the machine with a placement impeller, the turbine have the turbine cavity of a placement turbine, the compressor
Compressor volute casing with a continuous annular with opening, the compressor volute casing top with diameter greater than bottom
Diameter, and seamlessly transit between the two, the executor is arranged on bigbore side above compressor volute casing, the turbine
Turbine volute casing of the machine also with a continuous annular with opening, the turbine volute casing top with diameter greater than under
The diameter in portion, and seamlessly transitting between the two, the turbine volute casing top heavy caliber direction and compressor volute casing heavy caliber
Direction is consistent, with the side of executor.
In order to reduce the waste of fuel oil, a bypass valve is installed at the gas turbine exhaust mouth.
Used as preferential, the bypass valve is spring air relief valve.
In order to improve the patency that gas flows through, the compressor volute casing and turbine volute casing are coated with ceramic inner layer.
In order to increase the flow of compressed air, the opening on the compressor volute casing and the complete UNICOM of impeller cavity.
In order to improve the flow of waste gas, the opening on the turbine volute casing and the complete UNICOM of turbine cavity.
The beneficial effects of the utility model are that compressor volute casing and turbine volute casing are designed to continuously by this utility model
The annular with opening little cavity, when gas flows through small-bore cavity, gas is compressed, and is then passed through heavy caliber
Expanded during cavity rapidly, form a vacuum environment, increase gas flow.In the case where engine displacement is not improved, but
The power of electromotor is improve, the work efficiency for consuming but improve turbocharger of fuel oil is further reduced.
Description of the drawings
With reference to the accompanying drawings and examples this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure:1. armature spindle, 2. compressor, 3. turbine, 4. executor, 5. impeller, 6. impeller cavity, 7. turbine, 8.
Turbine cavity, 9. compressor volute casing, 10. turbine volute casing, 11. bypass valves.
Specific embodiment
This utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram,
Basic structure of the present utility model is only illustrated in a schematic way, therefore which only shows the composition relevant with this utility model.
A kind of turbocharger for gasoline engine shown in Fig. 1, including the compressor 2 and turbine that are fixedly connected by armature spindle 1
Machine 3, is provided with executor 4, impeller cavity of the compressor 2 with a placement impeller 5 at the air inlet of the compressor 2
6, the turbine 3 has the turbine cavity 8 of a placement turbine 7, and the compressor 2 continuously has opening with one
The compressor volute casing 9 of annular, the diameter with diameter greater than bottom on 9 top of compressor volute casing, and smooth between the two
Transition, the executor 4 are arranged on bigbore side above compressor volute casing 9, and the turbine 3 is also continuous with one
The turbine volute casing 10 of the annular with opening, the diameter with diameter greater than bottom on 10 top of turbine volute casing, and
Seamlessly transit between the two, 10 top heavy caliber direction of the turbine volute casing is consistent with 9 heavy caliber direction of compressor volute casing, together
In the side of executor 4.
Turbine volute casing 10 is designed to into the little cavity of a continuous annular with opening, works as engine efflux
During Jing small-bore cavitys, gas is compressed, and then when through heavy caliber cavity, waste gas expands rapidly, forms a vacuum ring
Border, increases exhaust gas flow, and exhaust gas flow increase means that 7 rotating speed of turbine is faster, and 7 rotating speed of turbine is faster, the leaf of compressor 2
It is faster that wheel 5 also just turns；Compressor volute casing 9 is also designed to the little cavity of the continuously annular with opening, when gas stream
During Jing small-bore cavitys, gas is compressed, and is then passed through being expanded during heavy caliber cavity rapidly, forms a vacuum environment, increase
Charge flow rate, the bigger capacity of air inflow are also bigger, and thus even the home vehicle of small displacement can also be produced enough
Power needed for daily life.
For security consideration, a spring air relief valve is mounted with as bypass valve 11 in the exhaust ports of turbine 3, when
The waste gas that turbine 3 is ejected reaches certain pressure, and spring air relief valve can be blown open, from the waste gas one that turbine 3 is discharged
Branch Jing bypass is discharged, and so as to reduce by 7 rotating speed of turbine, 7 rotating speed of turbine has lowered the rotating speed of 2 impeller 5 of compressor certainly will
Can decline.
Executor 4 be there is also mounted in the entrance of compressor 2 simultaneously, executor 4 is opened compression when emergency brake
Air is discharged, and as executor 4 is arranged on 9 top heavy caliber side of compressor volute casing, aerofluxuss effect can be improved when aerofluxuss
Rate.
With it is above-mentioned according to desirable embodiment of the present utility model as enlightenment, by above-mentioned description, related work people
Member can carry out various change and modification completely in the range of without departing from this utility model technological thought.This reality
The content being not limited to new technical scope in description, it is necessary to its technology is determined according to right
Property scope.
