Injini injini isebenza kanjani?

Isistimu yokunikezwa kwamandla ye injini ye- injection noma, ukumane ubeke, umjovo uyisistimu yokudla okusetshenziselwa uphethiloli esetshenziselwa izinjini eziqhuba uphethiloli futhi inezinzuzo ngaphezu kwezinjini ze-carburettor.

Injini injini iqala kalula imoto kungakhathaliseki ukuthi yiziphi izimo zezulu. Isistimu enjalo ingakwazi ukuzilungisa ngesikhathi sokusebenza, iguqule ngokuguquguqukayo imingcele yokupheka, ingxube ye-fuel-fuel, ngokusekelwe kokufundwa kwezinzwa, ulwazi olunikezwa ku-unit control unit (ECU).

Kuze kube manje, injini ye -jectjector isiphelile ngokuphelele ukusetshenziswa kwesistimu ye-carburetor yangemva kwesikhathi. Ngokubonakala kwayo, ukuguqulwa kwe-overclocking kuye kwanda kakhulu, inani lezinto ezinobungozi ezikhishwe emkhathini liye lahleka, ukusetshenziswa kwamandla kagesi kuye kwehla. Ngokushesha uyaphendula ngisho nezinguquko ezincane kulo mthwalo.

Izinqubo zokujova zihlukaniswa ngokuya ngesimo kanye nenani lama-injection. Njengamanje, ethandwa kakhulu yiyona injini ye-injection enejola elishiyelwayo, lapho umbhobho ngamunye uhlinzekwa nge-cylinder ngayinye. Zonke injectors zixhunywe kumgwaqo lapho uphethiloli uphansi kwengcindezi. Yakha ipompo kagesi kagesi. Inani lamapayipi okujova ngaphakathi ohlelweni kuncike esikhathini sokuvula se-injection.

Kuzoze kube nini ukuvula, kulungisa i-computer (isilawuli). Idivayisi ye injini ye-injection iwukuthi, ngokusekelwe emphumela wokucubungula ukufundwa kusuka ezinjenini ezihlukahlukene, i-ECU iqala injini yokujola. Inzwa yokugeleza kwamanzi isetshenziselwa ukubala umjikelezo wokugcwalisa amasilinda. Umthamo we-air consumed ulinganiswa, bese i- unit control unit ivuselela emjikelezweni we-cylinder ukugcwalisa. Amandla engena injini anyuke abe ngu-10% ngenxa yokugcwaliswa kwama-cylinders, isikhathi sokushisa esiphezulu, esivumelana nemodi yokusebenza yenjini. Uma inzwa iphula, izibalo zenzelwe amatafula athile.

Inzwa yesimo se-throttle isetshenziselwa ukubala umthwalo esithombeni. Uma kwenzeka ushintsho ekusebenzeni kwenjini, umjikelezo we-cylinder ukugcwalisa i-angle of rotation ye-valttle valve.

Inzwa yokushisa ye-coolant isetshenziselwa ukunqunywa ukulungiswa kokunikezwa kwamafutha emingcele yokushisa nokulawula umshini kagesi. Uma ihluleka, ukufundwa akucatshangelwa, imingcele, kuye ngokuthi injini isebenza isikhathi esingakanani, ithathwe kuthebula eliphuthumayo.

Ukuze uhlelo lusebenze ngokuvumelanisa, isisindo se-polar esinquma isikhundla se- crankshaft sisetshenziselwa ukunquma ijubane lejinini, isikhundla se-crankshaft ngezikhathi ezithile . Uma injini yejectjector ingashintshi kahle, imane nje ayiqali. Uma le senzwa iphula, uhlelo ngeke lusebenze. Kubaluleke kakhulu, futhi uma, ngokuhluleka kwamanye abalawuli, imoto ingahamba, ngaphandle kwayo imoto ngeke iqale.

Esikhathini sokufaka injection kukhona impendulo - ohlelweni lokukhipha, ngokushesha ngaphambi kokuba i-catalyst, inzwa ye-oksijeni yokuqukethwe emagesi okukhipha imoto (ebizwa ngokuthi i-lambda probe) ifakiwe. Ulwazi olunikezayo lisetshenziselwa uhlelo ukulungisa inani elifanele lephethiloli elinikezwa ohlelweni lokujova, ukugcina ngokunembile imingcele edingekayo yenhlanganisela yokusebenza, ngakho-ke, ukusetshenziswa kwamapayipi kuyaba ukonga ngokweqile, kanti izinga lokushukela lokukhipha igesi liyancipha.

Nazi izinzwa eziyinhloko ezidingekayo ekusebenzeni kwesistimu yejectjector. Isistimu yokunikezwa kwamandla ye injini yejectjector, kuye ngokuthi iyiphi injini efakiwe emotweni yakho, ingahlonywa ngabalawuli abahlukahlukene.
