Ngikuphi okuhlukileko kuneGreyidini injini ezine-unhlangothi - a Luhlatiyo

Yini ehlukanisa injini ezimbili-unhlangothi of ezine unhlangothi? Umehluko ephawuleka kakhulu - ke ezivuthayo ingxube ukuthungela izindlela, okuyinto kungabonwa ngokushesha umsindo. Ababili-unhlangothi injini Likhipha Ukuduma komsindo ephezulu uphonswe ngokuvamile elikhulu kakhulu, kuyilapho isici ezine-unhlangothi we Purr nenokuthula.

isicelo

Ezimweni eziningi, umehluko futhi ikakhulu iyunithi umsebenzi nophethiloli yayo kahle. Ngo ezimbili-unhlangothi izinjini, ukuthungela kwenzeka yonke inguqula-mbuso crankshaft, ngakho amandla kabili-unhlangothi ezine, lapho ingxube ephakamayo kuphela ngemva ngokushintshana.

Ezine-unhlangothi izinjini ukonga ngaphezulu, kodwa usinde ezibizayo. Zivame ogibele izimoto nemishini, kuyilapho kumadivayisi ezifana utshani mowers, Scooters nezikebhe ukukhanya, kaningi emfishane ezimbili-unhlangothi onobuhle. Kodwa uphethiloli generator, isibonelo, kungachazwa njengendlela ezimbili-unhlangothi, ezine-unhlangothi futhi. scooter injini nakho kungaba kwanoma yiluphi uhlobo. Umgomo we operation lezi izinjini ngokuyinhloko okufanayo, umehluko kuphela inqubo kanye nekusebenta energy conversion.

Kuyini wayeshaywe unhlangothi?

Nokusebenzisa kabusho imikhiqizo esisebenzile uphethiloli kuzo zombili lezi zinhlobo motors ephethwe ngabantu abane ukubulawa ezilandelanayo izinqubo ezihlukahlukene, eyaziwa ngokuthi imijikelezo. Ijubane lapho injini sidlula nemigoqo, - yilokhu ihlukile injini ezine-unhlangothi.

Umjovo lokuqala ikhono lokungacasuli. Lapho piston wehlela uMbhalo bese valve itheku kuvula ukuvuma emoyeni-fuel ingxube ekamelweni amandla omlilo. Okulandelayo kuba unhlangothi kokucindezelwa. Ngalesi unhlangothi valve itheku uvala kanye piston ihamba phezulu uMbhalo, ukugxisha amagesi iqhele khona. unhlangothi mjikelezo uqala lapho ingxube ephakamayo. Kulesi inhlansi kusuka inhlansi wokhela amagesi onomfutho, okuholela ukuqhuma, amandla awo odlulela piston phansi. Udaba zokugcina ikhono lokungacasuli: i-piston evuka uMbhalo, futhi valve esidayisa kuvula ukuvumela qeda amagesi ophumayo esuka egumbini amandla omlilo bakwazi ukuqala futhi inqubo. Reciprocating piston uzungeza a crankshaft, torque zazo udluliselwa izingxenye ukusebenza zedivayisi. Lokhu kwenzeka omlilo amandla is ibe ezinyakazayo Translational.

Sebenza ezine-unhlangothi izinjini

Ngo indinganiso ezine-unhlangothi izinjini ingxube ephakamayo ngamunye crankshaft revolution yesibili. Ukuzungelezisa shaft ashukumisa isethi eziyinkimbinkimbi izindlela ngoba undiza ukubulawa ukulandelana imijikelezo. Ukuvulwa kwe-eyanele noma qeda valve esebenzisa umgodi cam okuyinto yanjalo depresses le rocker. Buyela isikhundla avaliwe valve kwenziwa entwasahlobo. Ukuze ugweme ukulahlekelwa kokucindezelwa, kubalulekile ukuthi valve Abut ikhanda isilinda.

Umsebenzi ezimbili-unhlangothi injini

Manje ake sibone ukuthi yini lihlukile injini ezine-unhlangothi ngokuvumelana nesimiso umsebenzi. Ngo ezine-unhlangothi izinjini, zonke izenzo yenziwa ngesikhathi umjikelezo eyodwa crankshaft, ngesikhathi unhlangothi piston kusukela phezulu iphuzu efile kuya phansi, bese isipele. Exhaust (ukukhipha) fuel injection futhi kuhlanganiswe iwashi umjikelezo owodwa, ngemva kwalokho ingxube wokhela futhi amandla okuholela ekutheni piston phansi. Lo mklamo kungabi nesidingo mshini valve.

Isikhundla valve hlala ukuvuleka ezimbili ezindongeni omlilo ekamelweni. Lapho piston ngenxa amandla omlilo amandla ihamba phansi, lo mbhalo osenyameni kuvula ukuvumela qeda amagesi ophumayo esuka egumbini. kwakhiwa Lapho ushayela phansi a cleaner is e uMbhalo, ngenxa okuyinto ngokusebenzisa ndima itheku ngokufanele ngezansi ngaphakathi ungenisa emoyeni nophethiloli ingxube. Lapho piston ihamba phezulu licindezele iziteshi eyeqayo e uMbhalo igesi. Kuleli qophelo, ke kwabangela yenhlansi ipulaki, futhi yonke inqubo echazwe ngenhla okuphindaphindiwe futhi. Okubalulekile, ingxube ephakamayo ku izinjini yalolu hlobo nge Ukujikeleza ngamunye, okuvumela ukuba kukhishwe kuzo amandla amaningi, okungenani okwesikhashana.

Isilinganiso nesisindo namandla

Ababili-unhlangothi izinjini ezisilungele kangcono amadivayisi ukuthi ziyadingeka Ukuvutha fast and ngokuzumayo amandla kunokuba umsebenzi iyunifomu isikhathi eside. Ngokwesibonelo, ski jet nge injini ezimbili-unhlangothi ngesivinini ngesivinini esingaphezu iloli nge-unhlangothi ezine, kodwa yakhelwe uhambo iDemo, kuyilapho iloli angahamba amakhulu amakhilomitha ngaphambi kokuba ukuphumula ababekudinga. Okuphansi ezimbili-unhlangothi ubude msebenzi offset ngumuntu isilinganiso eliphansi isisindo ukuze amandla: lezi izinjini ngokuvamile nesisindo esincane, ngakho ukusebenzisa ngokushesha futhi afinyelele lokushisa ezisebenza. Ukuze ukunyakaza kwabo futhi kudinga amandla kancane.

Yikuphi injini kungcono

Ezimweni eziningi, ezine-unhlangothi izinjini ongasebenza kuphela isikhundla esisodwa, kuyilapho-stroke ezimbili kule ndaba yilena bafune. Lokhu kungenxa yokungabikho yinkimbinkimbi izingxenye ezinyakazayo, kanye umklamo pan uwoyela. a sump ukuhlinzeka Lubrication okunjalo yenjini, ngokuvamile samanje kuphela ezine-unhlangothi amamodeli, futhi kubaluleke kakhulu ngomsebenzi wabo. Ngo ezimbili-unhlangothi izinjini ngokuvamile akudingeki Pallet ezinjalo, ngakho-ke abakwazi usetshenziswe emazingeni sanoma yisiphi isikhundla ngaphandle ingozi uwoyela splattering noma amafutha uphazamisa inqubo. For Amadivayisi ezifana yokusaha, ngamasaha isiyingi namanye amathuluzi ephathekayo, ezifana nokuvumelana nezimo kubaluleke kakhulu.

Okokhelekayo kahle futhi ingxenye kwemvelo

Ngokuvamile kuvela ukuthi izinjini icwecwe futhi okusheshayo engcolisa umoya kakhulu futhi kudle ngophethiloli. Ngesikhathi phuzu ezijulileyo piston lapho ekamelweni omlilo ligcwele inhlanganisela igesi, ezinye fuel kulahleka, ukuwela imbobo yokuxhuma. Lokhu kungabonwa yiwo wonke isibonelo injini; uma ubuka eduze, uzokwenza out emhlabeni ezinemibala izindawo oily. Ngakho lolu hlobo izinjini ezibhekwa nokungabi udoti. Nakuba imodeli ezine-unhlangothi, kancane usinde kancane, kodwa kuzo uphethiloli uyaphakama ngokuphelele.

Izindleko ukuthola kanye nokugcinwa

motors ezincane ngokuvamile engabizi, kokubili ngokoMthetho othenge kulo kanye nesondlo. Noma kunjalo, zenzelwe ukuphila isikhathi eside okungenani. Nakuba zikhona izici ezithile okuhlukile, iningi labo lungadizayinelwe operation okuqhubekayo isikhathi esingaphezu kwamahora ambalwa futhi yakhelwe ukuphila service esikhathini esingeside kakhulu. Ukungabikho ehlukile Lubrication uhlelo futhi kuholela yokuthi ngisho izinjini engcono yalolu hlobo kuqhathaniswa ngokushesha ziguge bese uba engenamsebenzi ngenxa ukulimala izingxenye ezinyakazayo.

Ngokwengxenye ngenxa yokuntuleka Lubrication kule uphethiloli, eklanyelwe ugcwalise ezimbili-unhlangothi injini isikuta, isibonelo, kubalulekile ukuze ungeze ethile amafutha akhethekile. Lokhu kuholela izindleko ezengeziwe futhi kokuhlupheka, kodwa futhi kungadala umonakalo (uma ukhohlwa uphalafini). Motor 4-stroke, ezimweni eziningi kudingeka okungenani ube yesondlo nokunakekela.

Yikuphi injini kungcono

Kulesi etafuleni, kuchazwe kafushane, ihluke injini ezine-unhlangothi.

Iphinde libonisa izici emihle nemibi ngayinye kulezi zinhlobo ezimbili.
