Alternative propulsion. A Rotary engine: qa'ida ta aiki, ikon yinsa, da kuma ra'ayoyi

Tunanin yadda da yawa motocin akwai a cikin duniya. Kusan 99% na jimlar abin hawa jiragen ruwa na duniya da mover - fistan engine. Wannan engine ne abin dogara da kuma riga na dogon lokaci sarrafa a daban-daban na motoci. Amma baya ga labarin. Bayan da juyin juya halin masana'antu, wadda aka sa ta cikin zuwan tururi engine, duniya garzaya da ƙafafun. Babu wani mai rai tuki da karfi, wanda shi ne quite mai yawa da matsala, don haka shi ne mai tsananin kyau. Amma idan yawa Sauki da mataki na Rotary engine ra'ayi amfani a cikin Mills har yanzu aiki a cikin iska. Just to ba abin mamaki me ya sa haka.

Saboda haka, a haifi more saba mana na fistan engine ya ba da iko ingantaccen tsalle. Mu tuna da manufa na aiki. A daya da kuma guda rufaffiyar sarari dabam matsakaici da kuma aiki girma. By allura na man fetur da kuma iska da aka halitta a cikin aikin fistan. Ya, bi da bi, aka kinematically haɗa ta shaft ta crank inji hadadden tsarin. Translational motsi (fistan modifies ƙarar) ne tuba zuwa cikin rotational motsi na shaft. Idan ka dubi wani Rotary engine, da aiki da ka'ida zai zama da ɗan daban-daban.

A Rotary engine don haka ya kira saboda babban aiki part - wani na'ura mai juyi, ba plunger. A na'ura mai juyi a cikin irin wannan engine da aka gabatar a cikin nau'i na m treugolnikoobraznogo kashi, cikin abin da akwai wani rami tare da hakora. A stator ƙunshi matsanancin harsashi, da gefen zobba da kuma na ciki shaft da ma'abota hakora ne muhimmanci karami diamita. Wannan shi ne daya da irin - da Rotary engine. Ka'idar aiki na na'urar da shi ne da ɗan sabon abu a cikin wannan na'ura mai juyi ne juya asymmetrically dangi da engine cibiyar. Kamar haka a daya juyin juya halin faruwa kamar yadda mutane da yawa kamar uku aiki zagayowar a cika allo (dangi da fistan). Wannan shi ne a cikin wani dunƙule.

Idan, duk da haka, a cikin daki-daki, da manufa na aiki da irin wannan: iska ci, matsawa, man allura, da saki (tsawo). Irin wannan sake zagayowar da aka aiwatar a cikin fistin da ciki konewa engine, amma kawai aikin yi daidai da 6-Silinda ciki konewa engine na fistan irin. Amma me ya sa, sa'an nan, da manufa na Rotary engine ba a sanya juyin juya halin? Amsar mai sauki - ba haka m kamar yadda ya dubi. Wannan irin ciki konewa engine da hannu a kusan dukkan duniya brands, ciki har da na cikin gida. Muna yin duk abin da, amma shi ya juya ga saka a cikin yi a cikin raka'a. Jita-jita da shi cewa Felix Wankel fara aiki a kan engine cikin shekaru 19. Amma wannan shi ne wuya, domin yayin da fasaha ci gaban da aka raunana, masu sana'a da ilimi - a alatu da kuma rarity.

Duk da haka, mun san daga tarihi, cewa ya samu aiki a buga fasaha ɗaba'ar. Wannan aiki shi ne farkon ga Wankel engine a cikin duniya da fasaha. An sani cewa shi ne ya fara rayayye ci gaba da wannan ra'ayin, haka cewa akwai wani sunan da irin wannan engine - da Wankel engine. Baya ga tambaya - don me Rotary injuna bai zama tartsatsi? Amsar za a iya samu a amfani ko rashin amfani da ciki konewa engine makirci.

Abũbuwan amfãni daga aikin da cewa yana da wani Rotary motor (aiki manufa aka bayyana a sama) ƙarya a cikin wadannan abubuwa:

- High ikon fitarwa.

- sauƙi na zane (a kwatanta da fistan).

- ba su da iyaka (matattu) dige;

- ba ka bukatar ƙarin abubuwa (crank inji).

Ko rashin amfani wannan irin:

- wata babbar load a kan bearings da kuma hakora.

- fast zafi fiye da kima;

- haduwar sealing mutum bẽnãye.

Zai ze cewa Rotary engine aiki manufa yana da mafi alhẽri daga wannan wani fistan engine. Ko da more abũbuwan amfãni fiye da disadvantages, kuma suka (amfanin) ne na bayar da muhimmanci. Amma Developers sun gaza mayalwaci kawo barga aiki zuwa aiki zagayowar misali. Duk da haka, akwai ban. A lokacin, abin hawa Ro-80 aka bayar da lakabi "Car na shekara 1987". Kuma shi ke da wannan adadi.

Yau, da kalubalen da fuskantar da injiniyoyi lokacin, quite warware. Sassa za a iya sanya daga composites kuma high-ƙarfi gami. Amma maƙeran abin hawa suna a cikin wani sauri zuwa sababbin abubuwa. Zai yiwu saboda da cewa irin wannan engine aiki ne kawai tare da mafi ikon yayin da ciwon wata babbar kudi. Bambanci da wannan tare da farashin man fetur da kuma reserves na albarkatun, da kuma samun wata babbar hangen zaman gaba, wanda aka yiwuwa ba ƙaddara ta zama wani taro.
