4-unhlangothi injini: ukusebenza

imishini amandla uhlobo kubalulekile okukhethiwe. 4-sohlangothi 2-stroke - Namuhla, kukhona ezimbili ongakhetha kukhona.

Izici

imishini Power usebenza esekelwe ukunwetshwa amagesi ngesikhathi Ukushisa okwenzeka phezu ukuthungela uphethiloli bengena ingaphakathi isilinda. Abaningi banomuzwa wokuthi injini 4-stroke Briggs Stratton linikeza ukusebenza okungcono. Ukuze uthole impendulo esiqondile, kubalulekile ukuqonda izici zombili izinhlobo umsebenzi.

Crank design futhi indlela obhekene nokusatshalaliswa igesi - lawa izingxenye eziyinhloko ohlelweni yilezi kubaluleke ukuqinisekisa ukuthi izingxenye okugcotshwayo ukuthungela namandla.

kudivayisi Crank okuhambisa ukuchayeka oyifunayo ekwandiseni amagesi, kuyilapho mshini owabayo kubo eletha uphethiloli esikhaleni isilinda.

4-unhlangothi injini libhekene ukonga uphethiloli ukusetshenziswa, akukho ingxube ezivuthayo ku qeda, ezingeni engaphansi eliphezulu umsindo lidlalwa, kanye imvelo, ngakho wathenga ukusabalala izinkampani eziningi wahlanganyela ukukhiqizwa izimoto.

Kanjani ezimbili-unhlangothi injini

Yonke inqubo kusekelwe unhlangothi zokusebenza kanye kokucindezelwa.

I piston ngokuyisisekelo ezikhundleni ezimbili - iphuzu efile aphansi kanye engenhla. Lapho usuka eyodwa kuya kwenye, futhi baprofetha yanjalo ohlabayo uphuma khona, khona-ke iqala cindezela samanje igesi uMbhalo. Ngalesi sikhathi, ingxube fuel ephuma port itheku futhi ekamelweni crank indlela, kwaba yena abangena kamuva uzobe onomfutho.

Uma umoya nophethiloli evala ukufinyelela esiphezulu zlib isilinganiso, i- inhlansi kagesi, ivela inhlansi wokhela kubo. Ngalesi sikhathi, kwakheka ingcindezi, ukukhuthaza ukuhamba piston iphuzu aphansi ngenxa waba ukwanda okukhulu kwezincwadi igesi ingxube lokushisa. Phakathi ukunyakaza kuvula port esidayisa kanye nemikhiqizo elise amandla omlilo. Ingxube onomfutho njengoba uhamba piston ephendukela egumbini amandla omlilo, kanyekanye kuvula ifasitela ukuzwakalisa.

ngezici ezinhle nezimbi

Mshini kuyahluka isamba elanele nemibi, phakathi lapho uphethiloli okusezingeni eliphezulu ukusetshenziswa, njengoba iningi usuke udlale ngesikhathi. Lokhu kungenxa ukukhululwa olungaphelele ingxube umusi ngesikhathi kuvulwa ngesikhathi esisodwa qeda kanye behlwaya nezimbobo. Kufanele futhi wazi ukuthi okuqhubekayo ukugeleza uwoyela, njengoba kuyingxenye mix, futhi ngaphandle ngeke kube injini. Esinye isici negative itholakala okuqhubekayo kuhlangana nophethiloli.

Mshini push-silingo has a isisindo amancane Ubukhulu kuka abakwazi ukuqhosha injini 4-stroke. Kodwa ngokuhamba ukusebenza imoto, iletha izinkinga ezingaphezu, yingakho le okufana kuvamile emkhakheni yokumodela, okuyinto ugcizelela zonke amakhilogramu owengeziwe.

Kanjani-injini ezine

Kuyinto ehluke ngokuphelele kweyabanye sabafowabo ukuxegiselwa. Isimiso 4-unhlangothi injini umjikelezo yakhiwa ngokulandelana eyanele, kokucindezelwa and qeda unhlangothi, lapho kutholakala ukusetshenziswa kwaso, uhlelo valve.

I piston kuvula itheku yokuhamba phansi, bese le ngxube ezivuthayo ingena uMbhalo ngesikhathi esifanayo, ingxube ukusebenza ngemva ukuxubana esele wokuqamba asetshenziswe.

Izinqubo ehlelekile ukuphinda, in the ukulandelana ebekiwe Kungumsebenti umjikelezo, zenzeka kuwo wonke amasilinda futhi unikeze ubambe umsebenzi mechanical ngenxa energy conversion.

isithunzi

Injini emotweni ezivamile usebenza ngesisekelo umjikelezo ezine-sigaba, kutawenteka ngesikhatsi ukunyakaza ezine piston noma ezimbili linemibhikisho we crankshaft.

4-stroke udizili has a indlela ehlukile ngokuphelele ukuthungela inhlanganisela ezivuthayo futhi lasungulwa njengoba kuqhathaniswa samuntu carbureted. Umehluko omkhulu kule unhlangothi eyanele, njengoba e uMbhalo udizili ingena emoyeni eliwu lokushisa eliphezulu amagugu, kanye nophethiloli is atomized ku ngomzuzu izinhlayiya wokhela bedle ezingeni lokushisa.

4-unhlangothi injini has e oyiyo le sump uwoyela, lesi sici unesibopho zokugcoba, ngokunembile, okwesikhathi khona unomphela ezingeni isethi. I futha uwoyela lidlulisela kwento uhlelo Lubrication futhi ihambisa phezu kwezindonga engaphakathi isilinda. Ngenxa yalokho, ngomshikisho we piston kuyehla amafutha ifilimu elincanyana. annular izakhi bushelelezi Special ukuvimbela ingress uwoyela ketshezi egumbini amandla omlilo yi qeda ukubuya. Kulesi futha uwoyela lisetshenziswa izinjini ephethe namandla 5 l / c. Kwezinye izimo, le igrisi isakazwa inkungu ukuba olunikezwa crankshaft.

Ukuze 4-unhlangothi injini ebangela ezincane umthwalo degree, ngenxa la mafutha ifika njalo lemali edingekayo, ngaleyo ndlela kwande ukuphila inkonzo mshini.

Ngenkathi, eyodwa kuphela igrisi ushintsho. Kufanele kuqashelwe ukuthi kubalulekile ukuba ngezikhathi uhlole izinga uwoyela, nakuba ngeke ngokuzumayo zinyamalale. Namuhla, abakhiqizi kwaba lula umsebenzi abashayeli ifakwe onobuhle yesimanje izinzwa ekhethekile ukulawula ezingeni uwoyela labika isidingo ukulishintsha.

Umehluko omkhulu

Njengoba kuphawulwe ngenhla, izinhlobo ezimbili motor abe umehluko eliyisisekelo lapho itholakala Lubrication yenqubo ezimbili-unhlangothi, ukuze uphethiloli nowoyela ingxube okuyinto kamuva zishiswe. Abanye babo baye uhlelo ekhethekile ufakela uwoyela kuya crankcase, kodwa incazelo ayiguquki - uphethiloli uyaphakama ndawonye ngamafutha. Ngenkathi Chinese 4-unhlangothi injini "Lifan", kanye nanoma yimuphi omunye uhlelo efanayo, ifakwe izindlela ekubuyiseni amafutha egunjini elikhethekile.

uthambise

Uma sicabangela umehluko ekhona in izinjini, uwoyela motor kumelwe zivumelane nalokho okufunwa ahlukahlukene:

• namafutha ezine-unhlangothi indlela okufanele ifa lubricity okusezingeni eliphezulu, okuyinto zihlala zinjalo ngokuhamba kwesikhathi;
• ngoba olunye uhlobo kumele omlilo esiphezulu igrisi nge sakugcina imiphumela asalile ngesimo umule nomlotha.

Njengoba sekuzoqala khona izinjini ezivamile ziphuzo zazihluzwa of petroleum imikhiqizo esetshenziselwa Lubrication zokukhiqiza. Ukwakheka kwaba kokubili ongakhetha okufanayo. Isidingo ukudala amafutha entsha musa kuphakama kusukela lokuthi injini 4-stroke has a amandla ongaphakeme, futhi ngenxa yalokho, ukuguga ongaphakeme nomthwalo ongaphakeme ku izingxenye. Kamuva, esiqiwini isiqediwe izingoma ukwenyuka kancane ngesivinini ngesikhathi ukusebenza kanye nemingcele ezivamile. Le nkinga yaxazululeka ngokusebenzisa izithasiselo - izithasiselo esikhethekile motor amafutha. Namuhla kakhulu ngcono izici igrisi.

amandla

Kukholakala ukuthi namandla kakhulu izinjini 2T ngenxa ukusetshenziswa ngokugcwele uphethiloli amandla phakathi ezimbili linemibhikisho shaft. Lokhu akulona ngempela iqiniso, ngoba kule samuntu uMbhalo, kunokusebenza olunye uhlobo motor ayinakho isakhiwo ebalulekile, futhi ingxenye yalo ewela esidayisa futhi itheku ukuvuleka, ngokulandelana, umthamo ezincane uphethiloli combusted.

Ubulula ngokubulawa 2T indlela okubangwa ukusetshenziswa njengoba inhlanganisela igrisi uphethiloli nowoyela. Ukusebenza ingxube equkethe igrisi elinesimo ongaphakeme amandla ukukhululwa. Design izici eziye zaholela ekubeni ubone kukhucululwe fuel ingxube ukugeleza, okuyinto ebangela ngempela ingxenye enkulu. Ngakho injini 4-unhlangothi-Chinese ine ukubulawa more xaka futhi ngenxa yalokho, inani ezincane Ayisuselwe ezivuthayo. Okungukuthi, 2T izinjini kukhona amandla amaningi kuphela kwibanga emincane.
