FSI (Volkswagen) injini - hlobo luni injini, izici

Injini ye-FSI iwuhlelo lwesimanjemanje futhi oluhambisana nemvelo, esilwazi kangcono njengomjovo oqondile. Lolu hlelo lwasungulwa ngasekuqaleni kwawo-2000 ngabakwaVolkswagen futhi lwasetshenziswa ezimotweni zakwa-Audi. Abanye abakhiqizi bezimoto baye benza intuthuko yabo kule ndlela, futhi izinjini zabo zisetshenziselwa ezinye izifinyezo:

I-Renault - IDE;
I-Alfa Romeo - JTS;
Mercedes - CGI;
iMitsubishi – GDI;
Ford - EcoBoost nokunye.

Kodwa zonke lezi zinjini zakhiwe ngesimiso esifanayo.

Izici zalolu hlobo lwenjini zimi kanje:

ukuba khona kwamaphethini amabili okugeleza kukaphethiloli - izifunda eziphansi neziphezulu zokucindezela;
iphampu kaphethiloli efakwe ngqo ethangini iphampa uphethiloli ohlelweni ngengcindezi ecishe ibe ngu-0,5 MPa, ukusebenza kwepompo kulawulwa yiyunithi yokulawula;
i-fuel fuel iphampu kuphela inani elilinganiselwe likaphethiloli, leli nani libalwa yiyunithi yokulawula ngokusekelwe kudatha evela kuzinzwa ezihlukahlukene, ama-pulses angena epompo awenza asebenze ngamandla amaningi noma amancane.

I-high pressure circuit ibhekene ngqo nokuhlinzeka nge-cylinder block ngephethiloli. Uphethiloli uphonswa kujantshi ngepompo yomfutho ophezulu. Ukucindezela ohlelweni lapha kufinyelela inkomba ye-10-11 MPa. Irempu iyishubhu elihambisa uphethiloli elinezimbobo ekugcineni, umlomo wombhobho ngamunye ngaphansi kwengcindezi enkulu ujova inani elidingekayo likaphethiloli ngokuqondile egunjini elivuthayo lamapiston. Uphethiloli uxubene nomoya osuvele usegunjini lomlilo, hhayi ezindaweni eziningi eziwuthathayo, njengasezinjini ze-carburetor ne-injection yakudala. Ku-cylinder block, ingxube ye-air-fuel iqhuma ngaphansi kwesenzo somfutho ophezulu kanye nenhlansi, futhi imisa amaphistoni anyakaze.

Izinto ezibalulekile zesekethe ye-high pressure yilezi:

i-fuel pressure regulator - inikeza isilinganiso esinembile sikaphethiloli;
ama-valve okuphepha kanye ne-bypass - akuvumela ukuthi ugweme ukwanda ngokweqile kwengcindezi ohlelweni, ukukhishwa kwenzeka ngokukhulula igesi noma uphethiloli ngokweqile ohlelweni;
inzwa yokucindezela - ikala izinga lokucindezela ohlelweni futhi iphakele lolu lwazi kuyunithi yokulawula.

Njengoba ubona, ngenxa yohlelo olunjalo lwedivayisi, kwaba nokwenzeka ukulondoloza kakhulu inani likaphethiloli elisetshenzisiwe. Nokho, ukuze umsebenzi ohlanganiswe kahle, kwakudingeka udale izinhlelo zokulawula eziyinkimbinkimbi futhi ugxilise imoto ngazo zonke izinhlobo zezinzwa. Ukwehluleka ekusebenzeni kweyunithi yokulawula noma yiziphi izinzwa kungaholela ezimeni ezingalindelekile.

Futhi, izinjini zomjovo oqondile zizwela kakhulu izinga lokuhlanza uphethiloli, ngakho-ke izihlungi zamafutha eziphakeme zibekwe phezu kwezihlungi zikaphethiloli, okufanele zishintshwe ngokuhambisana neziqondiso ezisebhukwini lemoto.

Kubalulekile futhi ukuthi izinjini ezinjalo zinikeze ukusha kukaphethiloli cishe okuphelele, ngokulandelana, inani elincane lezinto eziyingozi likhishwa emoyeni kanye namagesi okukhipha umoya. Ngenxa yokusungulwa okunjalo, kwakungenzeka ukuthuthukisa kakhulu isimo semvelo emazweni aseYurophu, eNyakatho Melika naseNingizimu-mpumalanga ye-Asia.

Kule vidiyo uzobona futhi uzwe ukuthi injini ye-FSI engu-2 litre efudumele isebenza kanjani ne-run 100 km.
