Impulzni motor

[M-Fan]

Ja, tkole sm pr?u do teme. S prijatlam sma danes razglabljala o impulznih motorjih. Pa sm brsku po internetu pa sm vidu da jih uporabljajo celo pri avtomobilih. Zdej mam pa en problem..... Ne vem ?e sva midva iste motorje mela v mislih kot je tale na prvi sliki; (midva sva se pogovarjala o impulznih motorjih ki se uporabljajo pri letalih-tudi pri tistih na daljinsko vodenje).

 

Motor deluje takole(posplo?eno)

 

Ima polnilno komoro kjer se inducira plin(ne vem kter plin)potem pa ima dva izpuha; enega manj?ega in drugega, ki je ve?ji. v polnilni komori je uplinja?(deva iskro po doma?e)........ Potem pa ne vem ve? to?no. vem samo da so dve eksploziji in da so mo?i abnormalne.

 

?e kdo kaj ve? ve, ima kak znanstveni ?lanek oz. kej podobnega bi ga lepo prosu ?e lahk prpopa!

 

Hvala

 

P.S.

 

Sm mislu u slikarji narisat priblji?no sliko pa ne morm pripet. Jebat ga!

[wiperboy]

zanimiva tema bom malo pobrskal po netu pa te obvestim

[dravni]

Ta raketa V-1 je imela tak motor, nisem pa siguren ?igava je to pogruntav??ina

[komar]

Mislim, da nemcev....

[Marko_mx-3]

a ni to en nemec pogruntal in potem u?el v ZDA, kjer je pomagal pri programu Apolo. Kako mu je ime pa sem pozabil.

 

Pa ?e kdo gleda na Discovery-ju ko na odpadu delajo razna vozila in pripomo?ke, tam so imeli ta motor ki so ga morali sestavit iz odpadkov na odpadu in potem so tekmovali z njim.

[dravni]

Mislim, da nemcev....

 

Ja rakete jasno, ni pa nujno, da tudi motorja

[Symon]

Mislim, da nemcev....

 

Saj Wankel e bil tudi ?vab. Pa ga poglejte zdaj.

[poky]

Saj Wankel e bil tudi ?vab. Pa ga poglejte zdaj.

 

[Sishi]

Saj Wankel e bil tudi ?vab. Pa ga poglejte zdaj.

 

KVA TO POMEN ?!?!

[Boss]

a ni to en nemec pogruntal in potem u?el v ZDA, kjer je pomagal pri programu Apolo. Kako mu je ime pa sem pozabil.

 

a ni bil to en von, mislim, da se je pisal Braun - Werner von Braun al neki tazga :ne vem:

[Symon]

KVA TO POMEN ?!?!

 

Ni? slabega?

[Marko_mx-3]

Da je bil nemec zdaj pa ga delajo japonci ker nemci nimajo posluha zanj

[M-Fan]

Ker ta motor dela neposredno (brez vsakr?nih prenosov), me prou zanima kako ma pol avto to spelan - ?e ma to pod "haubo" pol ma 2m roru spelanih ?ez celo podvozje? Mal ?udno se mi zdi. A kdo ve?

 

Pri telem ?e zastopm, kaj pa pri obi?nih avtomobilih?!!!

[Symon]

Sam ne bi znal bolje napisati.

Nemci imajo posluh predvsem za dizle.

Pomoje imajo speljano preko turbine, da plini poganjajo lopatice ti pa potem avto

Pojasnila v zvezi z impulsnim (novim) sistemom za otto motorje so za?le v napa?no smer. Tu ne gre za turbinske motorje, ampak za nov na?in polnjenja motorjev s toplej?im zrakom in hlajenjem motorjev z ni?jo delovno temperaturo hladilne teko?ine.

Hot Air Induction and Cold Water

 

NEW induction and cooling system uses hot air and cold water

 

Hot air induction is used to increase the speed and pressure of combustion and when used in conjunction with cold water it maintains the optimum combustion temperature needed to maximise power with the larger volume of hot air forced into the engine by the Negative Supercharging process.

Hot air induction with cold water produces more power

If hot air induction is used with hot water, the combustion temperature becomes too hot which reduces the speed and pressure of combustion which reduces power. For this reason a cold water temperature between 45-50°C (113-122°F) must be used to keep the combustion temperature at the optimum level with the larger volume of hot air forced into the engine by the Negative Supercharging process. This allows hot air induction to increase the speed and pressure of combustion to produce more torque and horsepower. However, the much faster burn produced by hot air induction requires using the Negative Supercharging ignition timing which uses a unique advance curve with less total advance to prevent pre-ignition (pinging).

 

For example,

 

If the air induction temperature

 

* FALLS below 40°C (104°F), Negative Supercharging will produce less power the colder the air, even if the water temperature is increased to above 82°C (180°F)

* INCREASES from 40°C to 121°C (104°F to 250°F), Negative Supercharging will produce more power the hotter the air, but the water temperature must NOT exceed 50°C (122°F) to maintain the optimum combustion speed and temperature with hot air induction

 

If the water temperature

 

* EXCEEDS 50°C (122°F) with hot air induction, Negative Supercharging will produce less power the hotter the water

* FALLS below 40°C (104°F) with hot air induction, Negative Supercharging will produce less power the colder the water

 

Hot gas explodes with much greater force than cold gas

Hot gas explodes more violently, produces more combustion pressure and reaches its maximum pressure much faster than cold gas.

 

For example,

 

2 equal size gas cylinders filled with the same volume of gas are placed in an open field. The temperature of one gas cylinder is chilled to a cold 10°C (50°F) while the other gas cylinder is heated to a hot 121°C (250°F) or to just before it explodes. A spark is used to ignite the hot and cold gas cylinders and both explode with a tremendous force but the hot gas cylinder leaves a larger crater. The reason for this is, the less dense hot gas reaches its maximum pressure much faster than the more dense cold gas which causes the hot gas to explode with a much greater force.

 

Therefore, the engine is able to produce more power with hot air induction because the increase in power produced by the higher combustion pressure and faster burn of hot gas is much greater than the loss produced by less dense hot air.

 

 

Cold air induction with hot water is less efficient

 

During cold weather, cold air induction and hot water produce the optimum combustion temperature and maximise power. However, as the air induction temperature increases during hot weather so does the combustion temperature. This causes combustion to exceed its optimum temperature with hot water which reduces the speed and pressure of combustion which reduces power. Also, the slow burn produced by cold air induction transfers more heat into an already very hot cooling system which allows the engine to easily overheat during hot weather and produce pre-ignition (pinging).

 

Therefore, combining the fast burn of hot air induction with cold water and special ignition timing, the engine produces more power, runs cooler and during hot weather it eliminates the overheating problems caused by cold air induction and hot water.

Do zme?njave pri dveh vrstah tehnologij so privedli avstralski izumitelji sistema, ki sem ga opisal, s poimenovanjem impulsni sistem, ki (naj) izbolj?uje delovanje Otto motorjev na na?in, kot je zgoraj opisan.

 

Impulsni motor pa je dejansko najbolj enostaven reaktivni (jet) motor, ki je bil uporabljen pri prvi krilati bombi V-1. Deluje pa tako, da se zaradi hitrosti, ki jo je potrebno dose?i s pomo?jo drugega nosilca, skozi sesalni kanal nabija zrak v izgorevalno komoro, kamor se nato vbrizga gorivo in zmes z zrakom v?ge. V komori se tako pojavi velik pritisk, ki zapre ventil za dovod zraka na dovodni cevi za zrak. Edina pot izgorele zmesi je skozi izpu?no cev. Zaradi velikega pritiska se plini z veliko hitrostjo usmerijo skozi izpu?no cev, pri tem pa se ustvari precej?nja reaktivna sila. V komori se zaradi inercije plinov ustvari pod pritisk, v sled katerega se ventil ponovno odpre in zrak ponovno polni izgorevalno komoro in postopek se ponavlja. Motor deluje pribli?no tako kot se gibljejo morski glavono?ci (lignji, sipe...)le, da pri veliko vi?jih hitrostih. V-1 je imela v kratkem ?asu po lansiranju hitrost skoraj 700km/h.

Kako deluje tisti dvocevni pulsirajo?i motor na zemeljskih vozilih, ne vem, vendar si tega sistema ne morem predstavljati brez komprimiranega zraka (jeklenke). Dve cevi pa so verjetno za to, da delujeta izmeni?no in tako zmanj?ata interval med posameznimi impulsi. Taki motorji nimajo prakti?ne uporabnosti, razen za kake dirke naravnost.

Je pa uporaben drugi turbinski motor, omenjen v debati. Ta ima rotirajo?a kompresor in turbino, s katerih osi se preko reduktorja mo? prena?a na mehanski pogon. Motorji, v primerjavi z velikostjo, dajejo veliko mo?, vendar pa so za avtomobilsko uporabo neprimerni, zaradi velike porabe goriva.

enostavno in u?inkovito - zaradi konstantnih pokov je ta raketa oddajala zna?ilen zvok (kot kak zelo po?asi se vrte? diesel ) od katerega je London?anom ledenilo kri v ?ilah...

?e kako izgleda samogradnja turboshaft motorja (turbina s prenosom mo?i na gred). Lahko se kak entuziast preizkusi v izdelavi lastnega motorja.
