Abstract

The utility model relates to an air-drive turbine pressure intensifier device with round casing, which takes the air for drive. The cavity of the round casing is provided with eleven air inlets, one special air inlet and twelve air inlet guide plates inside. The turbine of the device is a radial-inward turbine with a plurality of vanes, and each vane has a radial part and an axial part. The air after filtrating by starting the engine can synchronously drive the radial part of each vane. A bundle of high speed airflow is collected to directly enter the special air inlet when the car runs, which makes the turbine during rotating repeatedly add a drive. So the outlet of the device outputs the air with the atmospheric pressure value larger than one and the rotating airflow in high speed to the air inlet system of the engine.

Description

Garden housing aerodynamic turbosupercharging devic 3

The utility model relates to the motor car engine supercharger arrangement that a kind of air is a power, especially to the garden housing aerodynamic turbosupercharging devic 3 of engine aspirating system input greater than the high speed rotating air-flow of 1 atmospheric pressure value.

The engine booster apparatus has several, and at home and abroad Ding Xing product mainly is the exhaust-gas turbocharger device.The motor of every installation exhaust-gas turbocharger device can both increase the mean effective pressure (Pe) of motor, has improved the engine combustion performance preferably, and function is clear and definite.But the problem of existence is that the power that promotes the turbine rotation is high-temp waste gas.For this reason, the average operating temperature of hydrostatic bearing in the device and floating axle all is not less than 450 ℃, makes the easy gum deposit matter of oil channel hole of floating axle stop up oil channel hole, causes floating axle not float and axis.The durable reliability of device is poor, and the relatively advanced country of this problem world car industry so far also is the problem that is difficult to resolve.What turbine adopted is high-quality refractory steel, and blade shape complexity, technology difficulty are big, for this reason the price of import exhaust-gas turbocharger device: 3000 yuan /～6000 yuan/, and costliness.And for example: " automobile powerful economizer " of " the whirlwind economizer " of Korea S, China, and " space wheel ", the said goods is claimed and is the pressurized machine working principle of walking back and forth.Device can both increase the charging efficiency of motor in automobile is used, and can effectively improve the engine combustion performance.The problem that exists is the limiting value of effect, still can not satisfy more best performance value of motor.During supporting installation, need matching and debugging hell to pay one by one, unstable properties.The patent No.; 991155625 " aerodynamic turbosupercharging devic 3 " and the patent No.s: 022024301 " four suction port wind turbine supercharger arrangements ", the effect of device all is clear and definite.But, the problem of existence: the structural design reason, the performance of turbine acceleration, revolution preferred values is had any problem in the device; Big and the inevitable big bad solution of contradiction of housing of device air inlet; Supporting connection is complicated.

The utility model purpose provides the garden housing aerodynamic turbosupercharging devic 3 that a kind of air is a power, in housing footpath, garden portion chamber 11 suction ports is set, 1 special suction port and 12 air inlet guide plates.Turbine is the multiple-blade centripetal turbine in the device, each blade all has warp-wise in the multiple-blade, when axial component starts when motor car engine one, air after the filtration is by air guide cover before the device, back air guide cover air just enters into 11 suction ports in the device case footpath portion chamber, 1 special suction port, effect at 11 air inlet guide plates, air after the filtration can drive the radial part of each blade in the multiple-blade simultaneously, so, the turbine acceleration is big, the rotation that revolution is high, make the air after the filtration form swirling eddy in the axial flow motion device outlet plenum of each blade in the multiple-blade again, when automobile running, gather a branch of high velocity air again at Che Nei through particular filter, special suction port in the straight inletting device, make the turbine that is the rotating driving force that superposes again, so, the turbine acceleration is bigger, revolution is higher, forming high speed rotating in the device outlet plenum this moment just enters in the automotive engine air intake system for the air greater than 1 atmospheric pressure value, effectively raise the mean effective pressure value (Pe) of motor, improved the engine combustion performance, supporting connection is simple.

The utility model purpose be achieved in that since device case be designed to the garden housing, so, in housing footpath, the garden portion chamber, be easy to, be provided with uniformly 11 suction ports, 1 special suction port and 12 air inlet guide plates.The radial part that has realized each blade in the multiple-blade turbine can receive driving force simultaneously, so turbine ability acceleration is big, revolution is high in rotation.Automobile driving speed is 60 kilometers/hour, the about strong breeze speed of wind speed on the vehicle body, 100 kilometers/hour of speeds of operation, the vehicle body wind speed reaches storm speed approximately after tested, so a branch of air of gathering on the car is a high velocity air, so the turbine acceleration is bigger in the device, revolution is higher.Because device is provided with back air guide cover, supporting connection is simple especially.

Owing to adopted such scheme, not only acceleration is bigger, revolution is higher for the multiple-blade centripetal turbine in the device; The device air inflow is big, volume is little, and convenient supporting connection, so the structure of device is simple especially.

Below in conjunction with drawings and Examples the utility model is further specified.
