1、Automobile Manufacture Profession Application High-tech Following ten high-tech certainly are not the nowadays automobileindustry high-tech complete, but they will be basic may represent theworld automobile future 20 years development situation. Therefore,makes a comprehensive understanding to these

2、 high-tech also to be ableto be able dynamically to grasp the world automobile for you thescience and technology to have the help. 1st, V10 engine Development company: BMW Application vehicle type: Valuable horse M5 The new style valuable horse M5 has provided V 10 cylindersnew engines, the V10 engi

3、ne displacement is 5.0L, the peak poweroutput is 378kW (507bhp), the maximum torque is 520Nm. The V10 engineuses the nature inspiration, enters the red area limit from 8250rpm(engine speed boundary). V 8 cylinders engines provides which withprevious generation M5 compare, the V10 output increased 25

4、%,guaranteed the 1L displacement to surpass 100bhp the output, thisenable M5 to have the vehicle race unusual performance。The V10 engine in order to balance the crank the revolution, established the air cylinder 90; In order to guarantee bearsexplodes the cylinder, high revolves and the vibration ri

5、gidity, itscrank case has used the rudder core skeleton structure. Supports thecrank the bearing to have 6, this company uses the support structureon V engine, still was for the first time. V10 engine each aircylinder has 4 valves, provides bi-VANOS (invariable valve structure). This engine necessar

6、y use gear box is 7 fast automatic MTSMG. The characteristic reduced the speed change time, compared withbefore SMG, the speed change time reduced about 20%. Moreover, it alsoestablished the coordinate movement pattern 11 kinds to select andmatch the way. V 10 cylinders engines are same with other s

7、pecialengines, is located the German Munich in this company the factory useflexible production line production After 2nd, hangs the curving car axle & WATTS connecting rod Development company: Plum Si runs quickly Application vehicle type: A-Class Plum side Sis ran quickly the company recently to an

8、nouncecomprehensively improved A-Class the small vehicle, and the autumnwill start in 2004 to go on the market. The new style A-Class theautomobile body size is long 3838mm, extends 1764mm, high 1593mm, thespread of axies is 2568mm. With the existing design similarity was thevehicle commander, Che K

9、uan and the spread of axies separatelyincreased 232mm, 45mm and 145mm. This is because has used the newdevelopment curving car axle after its automobile body as well as mayact according to the different conversion weaken strength the shockabsorber. This causes the new style A-Class when the ordinary

10、 travelhad the good absorption of shock effect, but when high speed curveenhanced the vehicles stability. Should say about that, new style A-Class behind was hanging has usedthe unprecedented form - is uses one kind to be able directly toconnect the wheel hub rigid car axle, then let the weight by b

11、elocated nearby the wheel hub the spring and the shock absorberundertakes together. This kind of car axle large is curving to front,the car axle central design has undertakes the tare center ofresistance. Behind is hanging about two sides crosswise each designto have, the position is slightly higher

12、 than the car axle.Looked from the plane that, two connections uses to theautomobile body installment spot is the WATTS type. Therefore, only toautomobile body transmission not after any change about strength around, but nearly does not transmit the strength. In otherwords, the crosswise rigidity hi

13、gh but around is low to the rigidity,belongs ideally is hanging the characteristic. In fact, latter washanging uses the rigid + WATTS connecting rod the design in Ma Zidathe first generation RX-7 and so on in the vehicle type also oncehas had the precedent, but all did not have A-Class to display so

14、clearly, after moreover A-Class has also avoided was hanging a side wheel hub before the direction for the axis rotation thisquestion. Latter hung the curving car axle center also to coordinatein the Monaka structure to use two steel plates, about the WATTSconnecting rod has used is high pulls takes

15、 shape (High DrawForm), but WATTS connecting rod central connecting rod for casting.3rd, steel aluminum built-up section automobile body Development company: BMW Application vehicle type: Valuable horse new 5 departments The new 5 departments are in the world first section use theinnovation the stee

16、l aluminum built-up section automobile. Thevehicles front part uses the aluminum material, the first sidekneading board and the front cover also use the aluminum materialmanufacture, around the A column automobile body other parts is madeby the steel products. Also, the first side kneading board and

17、 thefront cover also are uses the aluminum material to make. This newtechnical use, caused the entire vehicle weight (to regard vehicletype to be different) reduced 75 kilograms most much compared to itsrespective front generation of vehicle type. Because has used including the brand-new design alum

18、inum system/steelsystem automobile body structure, the consummation whole innovationscience and technology idea, the valuable horse is new 5 takes to theuser the splendid incomparable dynamic driving experience. The summarymentions, new 5 is the passenger vehicle while reduces the entirevehicle weig

19、ht, enhanced the use space and comfortableness,strengthened the fuel oil efficiency and has provided the strongerpower performance, simultaneously, the vehicle bridge loaddistribution is also more reasonable, achieves perfectly 50:50. The valuable horse new 5 departments chassis continued the BMW 7s

20、eries entire aluminum chassis in the very great degree, the rear axleof car has also manifested has come from the BMW7 series integral typeprinciple of design new characteristic, causes 5 departments thevehicle bridge structures definitely could satisfy from allbasic requests, like extremely good li

21、ne control and travel pleasureand so on.4th, GloCar changes color the automobile Development company: Ford Motor Company Application vehicle type: Ford wild horse The Ford Motor Company published to this April 24 has beenallowed to change the body color at will using LED the concept vehicleGloCar. T

22、his vehicle automobile body covered to project formed the translucentplastic kneading board, might use its internal the LED changeautomobile body exterior color. Its merit on roughly has two points,first is the security which at night goes. Because shines theautomobile body very easily looks at by o

23、ther vehicles clearly,therefore not only can reduce in the intersection and so on place thetraffic accident, moreover the automobile body 外板also may serve asgets on the brakes and changes and so on the indicating lamp. Moreoverrear area, but also may use in to tell the driver to pay attention tothe

24、maintenance distance between vehicles. Another merit is itsdesign, the automobile body may become outside the black any color. In addition, but also hopeful simplification production process.Because does not have to spray paint, therefore not only can simplifythe production process, but also can red

25、uce the air pollution.Simultaneously because the vehicle 外板only has one kind of color,but also can give the circulation and the sale brings conveniently5th, VOLVO fertile automobile peaceful brand-new measure Development company: Rich and powerful people car company Application vehicle type: VOLOV S

26、CC security conceptvehicle Statistics have indicated, the whole world has 500,000 peopleto die every year of the traffic accident, but is injured thepopulation is reaches as high as , this exactly is equal toBeijing at present the fixed population total! Therefore anoutstanding automobile first must

27、 pursue the security performancewhich is stands up to the most rigorous test, next is other functions.Although in world not that official organization in world mostsecurity automobile the title awards for VLOVO, but VOLOV indeed is the auto safety uncrowned king, even so VOLOV isfertile unceasingly

28、is promoting the new security measure as before,causes the automobile to become the humanity safest transportationvehicle.VOLOV the fertile newest initiative safety system has thebreakthrough in following two aspects: One is the world originates maycover the scotoma the camera supervisory system; Tw

29、o is the belt isaway from the monitor function the intelligent cruise constant speedsystem; Three, appears when the collision danger may send out thepolice to show and the automatic enhancement installment.So-called scotoma information system the main use is carries thecamera supervisory system with

30、 a vehicle, unceasingly monitors thevehicles two sides and the behind situations. Before in order toreduce the blind spot generally all above the rear view mirror todispose a wide angle attachment rear view mirror in outside a driverside vehicle, this was we frequently a small circular mirror which

31、sawabove the rear view mirror. Scotoma information system the principleis separately lays aside two speeds of response extremely high on each vehicle door on the rear view mirror, when anotherautomobile enters in, lays aside nearby the vehicle doorrear view mirror the police shows the lamp to be abl

32、e to glisten. Thedriver may know other vehicle is approaching, thus adopts dodges themeasure. Each the length is 9.5 meters, the widthis 3 meters, the vehicle carries the procedure which in the computersystem establishes regardless of in the daytime or at night all maymonitor all automobiles and the

33、 motorcycle, but cannot to anchor afterthe roadside vehicles, the roadside fence, has object and so onvehicles as well as lamp pole which the accident discards makes theresponse. So long as the vehicles speed surpasses 10 kilometers, thissystem can the volatilization, regarding other vehicles whichm

34、onitors, no matter is the speed this vehicle is slow scope or to bequicker than 70 kilometers/hour vehicles in 20 kilometers/hourvehicles this vehicle, this system all can accurately send out thewarning to the driver.The scotoma information system uses the technology first applies in2001 promotes VL

35、OVO in the fertile SCC security concept vehicle. Intelligent cruise constant speed system the goal is lets harnesswhile can with ease drive the vehicles on the state of roads goodhighway. This system may uninterrupted monitor the distance whichmaintains with the front vehicles between, and automatic

36、 controlvehicle speed in order to and it maintenance suitable safe distance.The driver so long as establishes the maximum speed and which the gooddriving needs is smallest after the front vehicles the time distancethen may activate the intelligent cruise. The time distance refersis defers to current

37、 vehicle speed this vehicle and the front vehiclecontact duration, this parameter may in change 1 to 3 seconds scopesin. If designated the time-gap is 2 seconds, then is 100kilometers/hour automobiles said regarding the speed, the safedistance approximately is 56 meters, but when the speed reduces t

38、o 70kilometers/hour times, the safe distance along with falls toapproximately 39 meters. The intelligent cruise constant speedsystem also can implement the entrance lane in the vehiclesconsideration which passes another vehicle. Coordinates with this set of system, the automobile must install aradar

39、 sensor in front of the vehicle, it may uninterrupted monitorthis vehicle the distance which maintains with the front vehiclesbetween, then adjusts the accelerator to control the engine the power,and when necessity gently activates the braking system to maintainwith the front vehicles between establ

40、ishes the time distance;Moreover the automobile gear box also must be the automatic gear box.Such intelligent cruise constant speed system can automatically actaccording to the transportation condition the change to change thevehicle speed, when the vehicles completely stop steadily up to.The automa

41、tic activation gets on the brakes and has the enhancement toapply the brake the function warning system is VOLOV the fertilenewest research results, mainly prevents follows the accident theoccurrence. This system may in have in the accident process differentstage to activate by the many kinds of way

42、s: When the automobileapproaches static or the movement obstacle but the driver makes theresponse by no means, the police shows the lamp to be able to glistenand to reflect on the windshield glass, simultaneously activates abuzzer. Above these new security measures gradually are applied, among thesc

43、otoma information system will go into production in 2004, and usingin 2005 in design automobile; As for other two kind of facilities atpresent not yet decided in which model Volvo automobile first appliesin. In addition, Volvo in the back sight child safety chair, was madthe curtain inversion in the

44、 board hood racing bicycle securitymeasure as well as the pregnant woman safety vehicle and so on manyrelated auto safeties aspect research all it may be said the ultraacme in the vehicle door the safekeeping of security science andtechnology.6th, hydrogen rotary engine Development company: Ma Zida

45、car company Application vehicle type: MAZDA RX-8 Ma Zida already RX-8 Hydrogen RE on has provided the RENESIShydrogen rotary engine in its use hydrogen and the gasoline two kindof fuels. First, the RENESIS hydrogen rotary engine has installed 4hydrogen spray nozzles in the RX-8 RENESIS engine outer

46、covering. Whenuse gasoline for fuel travel the engine and old funds RX-8 iscompletely same, uses two sides to enter the exhaust; When usehydrogen for fuel travel, the engine then passable has installed inthe RENESIS outer covering the spray nozzle direct injection hydrogen,because the hydrogen densi

47、ty is small, sprays the quantity to be muchmore than the gasoline, therefore each rotor provides two spraynozzles.When use gasoline RX-8 Hydrogen RE the peak power output is 154kW(210PS), when use hydrogen is 81kW (110PS). Maximum torque aspect,when use gasoline is 222Nm, when the use hydrogen is 12

48、0Nm. Becausemay use the hydrogen, this vehicle also has with the hydrogen relatedspare parts. In drives on the mat, has prepared the cut gasoline andthe hydrogen cut button, Chu Qingguan the pressure gauge (biggest 350standard atmospheric pressure), Chu Qingguan the thermometer (highest80). Moreover

49、, has outside the hydrogen fuel note entrance except theautomobile body on, but also has laid aside Canadian DynetekIndustries Corporations Chu Qingguan in the reserve box (biggest 350standard atmospheric pressure), for guaranteed the security RX-8Hydrogen RE to provide 4 hydrogen revelations instru

50、mentation. MaZida also made the hydrogen engine advanced version. Because thepresent uses time the hydrogen the peak power output will be lower,only has 81kW, therefore future will increase the motor assistance-like turbosupercharger and the oil electricity mixing arrangement onthe hydrogen engine.

51、Ma Zida the turbosupercharger may enhance theturbo-charged efficiency in the low rotational speed area through themotor auxiliary turbine revolution. In high rotational speed area,through ordinary exhaust turbo-charged. Also the equipment has the oilelectricity mixing arrangement, when low rotationa

52、l speed auxiliaryengine revolution.7th, ethyl alcohol examination vehicle key Development company: Saab car company Application vehicle type: Test stage Perhaps from now on one day, the traffic police will carry onthe ethyl alcohol examination in the roadside to the pilot the scenenot to be able aga

53、in to have, will not be because everybody has notdrunk, but was the vehicle owner early step knew the oneself ethylalcohol value surpassed the standard but not to drive started off,because had the Saab automobile wonderful invention - - Alcokey theethyl alcohol examination key.Statistics have indica

54、ted, in cause troubling which last year Europebecause the traffic accident got killed, after has reaches as high as25% is the liquor drives causes, but approaches three tenths in Swedenthis ratio. Therefore, Saab is researching and developing an item ofuniqueness, the volume dexterous strength of al

55、cohol inductor, assiststhe driver to observe the traffic law, after reduces the liquor thetraffic accident probability. Saab researches and develops Alcokeyofficially publishes at the security seminar which August, 2004 Swedenholds, its concept included has designed a small blowpipe on thevehicle ke

56、y, by a group of signals launchers connection to vehicle onelectronic control module, if the driver did the ethyl alcohol airflush test sample was discovered surpassed the legal permission thestandard value, then the system will cause the engine to maintain isunable in the static condition to start.

57、 Alcokey the liquor measuredthe key the concept also is set of precise automatic security systems.When the driver presses down on the remote control to open the gatethe button, the strength of alcohol inductor also along with it start,then the driver is treating the acorn tube mouth air flush, lets

58、thegas contain a group through the blowpipe interior to be similar to theneedle size the sensation, the gas interprets after the process, theresult can shows by way of the inductor on small green light or thesmall red candle. When demonstrated when green light, the key willtransmit all-clear the sig

59、nal to the vehicles electronic controlsystem, also will be measured through the liquor, was allowed to startoff; But if the test result is a red candle, all-clear the signalcannot deliver to the electronic control system, therefore thevehicles will maintain at the fixed condition, even if the keyinsertion also will be unable to start the vehicle. In thevehicle electronic control system immobiliser (start forbidsequipment) the software visible various countrie
