Description
Technical field
A kind of engine and assembly are the utility model is related to, relates generally to a kind of air motor.
Background technology
Air pollution has become international environmental problem, and motor vehicle exhaust emission turns into the major urban atmosphere in the world
The arch-criminal of pollution, therefore, everybody is ceaselessly exploring new-energy automobile.The mankind always have exhaustless marvellous idea：
Electric energy, Hydrogen Energy, solar energy, wind energy, nuclear energy, biomass energy, gas energy ... are wherein most noticeable will to count air-powered car
.
Air-powered car relies on air motor, and pressure energy is converted into mechanical energy, so as to drive vehicle forward.Early stage
Air motor is all the structure for employing similar steam engine, bulky, operating efficiency is low, can not meet to actually use need
Ask.Current research direction is that development structure is compact, the small pneumatic engine of high efficient and reliable.There is U.S. in addition to China in the world at present
The country such as state, Britain and France is carrying out the research of air motor and aerodynamic force car, is mostly advanced development in experiment,
There is not large-scale business application also.
Washington, DC university have developed an air using liquid nitrogen as power for 1997 under the subsidy of USDOE
Power prototype vehicle.Its used air engine has an old five cylinders array piston engine transformation.And U.S. north moral
Ke Sasi state universities have also carried out the research of liquid nitrogen power vehicle under the support of state cash technological project fund, are passed through using liquid nitrogen
The high pressure nitrogen that over-heat-exchanger obtains, a pneumatic vane motor job is supplied, be converted into mechanical work driving running car.
Carry fluid reservoir to be fully loaded with the case of 48 gallons of (about 182L) liquid nitrogen, travel 15 kilometers with 20kmph speed per hour, efficiency is low.
Professor C.J.Marquand of London University of Westminster devises the two-stage bias leaf of a prototype version
Chip air motor, the air motor weight 50KG, operating pressure 4.5MPa, using the eccentric leaf of each 12 blades of two-stage
Piece rotor, heat-pipe heat exchange system is applied on the air motor, and high pressure air is needed one before engine is entered
Demi-inflation is to absorb the heat provided by surrounding air in individual long tube type aluminum-made heat exchanger, and finally, efficiency is still lowly this
The problem of engine.
1991, French engineer Gury Negre obtained the patent of compressed-air power engine, its operation principle
It is to be advanced using the piston movement in the high pressure air driving engine cylinder body stored on car and then driving automobile, this is most
Close to air-powered car truly.French MDI companies have been set up under Gury Negre leader, it is special to develop pneumatically
Automobile, air-powered car AIRPOD of its achievement in research applied to TATA groups of India, 2.13 meters of vehicle commander, 275 kilograms of car weight, most
The big people of handling capacity of passengers 3, F-Zero are 70 kilometers.In-car puts a gas tank that can load 30MPa compressed airs, and 175 liters of volume is single
The secondary maximum driving range full of gas is in 200 kms.
The domestic research for air-powered car start it is later, the input product testing stage it is also less, wherein CCTV exists
In May, 2015 is reported auspicious day air-powered car.From the point of view of its operation principle, the power of auspicious day air force bus passes
Lead and have passed through a series of " compressed air-engine-generator-motor " this flow, than European MDI (by French engineering
Teacher Gury Negre are founded) air-powered car it is more complicated, therefore during the energy that loses it is also more.Therefore, air
The efficiency for being critically depend on air (gas) engine of power car.
Most of air engines are applied on the basis of original piston engine or vane pump, and pass through heat
The heated conversion for realizing energy of exchanger, realizes power output, not only complicated, it is important to which that efficiency is low, it is difficult to meet continuation of the journey
The requirement of ability.
Chinese document CN201410167469.4 discloses a kind of jet-propelled air engine of transformation, including blade wheel chamber and leaf
Take turns, the steam vent for spraying into hole and spraying compressed gas for spraying into compressed gas is provided with blade wheel chamber, impeller is installed by rotating shaft
In blade wheel chamber, impeller includes coordinating along the inner surface air gap for rotating side face and blade wheel chamber, and the inner surface of blade wheel chamber is additionally provided with change
Jet groove is pressed, is more than a space width along the distance between the rotation direction transformation jet groove of impeller and adjacent penetrating hole, when
Two working chambers before and after some leaf-teeth are connected by the transformation jet groove.By setting transformation jet groove so that spray into
The gas that hole sprays into can also do work again before being sprayed from tap.Efficiency that being intended that of the document improves engine and dynamic
Power, but the structure is similar to vane pump, efficiency is low.Meanwhile the setting of the transformation jet groove causes the air engine rotating speed
It is low, or even can not rotate.
