Pump-umlomo wombhobho: ngezigaba kanye ukulungisa

Minyaka yonke isidingo injini diesel ngokuvumelana nezimfuno ezifana amandla, ngemvelo futhi umnotho kuphela ezikhulayo. Futhi nje ukwakheka esiphelele ingxube oluvuthayo onganelisa lezi zidingo. Ngakho-ke, sonke isimiso fuel umjovo usebenza kahle, ukuhlinzeka ngomzuzu wafutha ngaphansi kwengcindezi okusezingeni eliphezulu.

uhlelo ezinjalo, elihlanganisa kwelinye iyunithi fuel injector kanye futha, futha-atomizer. Ngokufanayo, futha umfutho ophakeme, futha-injector sifaka ethile nenye ngesikhathi esifanele. Ngenxa yokuthi ngayinye amasilinda yenjini kukhona eyodwa injector, e isimiso esinjalo akukho futha fuel injection.

Iinsetjenziswa Imibhobho esemzimbeni zibandakanya ikhanda isilinda ngokufanele udizili iyunithi injector. Ngibalethe amandla phezu camshaft 4 has a cam ekhethekile. Ibutho phezu plungers iyunithi injectors idluliselwa ngokusebenzisa rocker. Ngenxa iphrofayili olukhethekile iyunithi injector rocker cam ukushayela wokuqala ngqo liphume, bese uwela ngobumnene.

Okwamanje uma kukhona ukwanda kokutheleleka kudlange yengalo rocker, le plunger icindezelwa ngesivinini phansi kakhulu. Ngakho-ke, kukhona high blood pressure. Lapho ingalo rocker iqale ukuhlakazeka kancane, njengoba plunger iqala ukubambezela futhi ukunyakaza iyunifomu phezulu. ukwakhiwa okunjalo ivumela fuel ukungena ophezulu ekamelweni ngokushelela, kungekho kumiswa air Bubbles. Isikhathi kanye nokulawula umjovo Solenoid ukulawula valve iyunithi injector. Ngenxa yale njongo, ngokusebenzisa electronic control unit bephethe voltage. Ngisho ngeziphambeko ezincane isitshalo imingcele kwenzeke spray petrol, injini uqala "umsindo."

Udizili injector futha kungaba izinhlobo ezintathu: piezoelectric, kagesi, electrohydraulic. Nge Solenoid umphini umlomo wombhobho hlela njengeringithoni uphethiloli kanye diesel, futhi ilungiselelo elula: umlomo wombhobho kanye valve Solenoid ngenaliti spray. Electro-injector kuphela efakwe diesel, okuyinto kunamathuba amaningi okuthi ukusebenza ohlelweni Caumont Ryle. Piezoelectric wacabangela diesel eziphambili kakhulu. iyunithi injector okunjalo kwabangela izikhathi 4 ngesivinini esingaphezu Solenoid, kanye Ukweqiwa injected fuel ngokunemba esiphezulu.

Ukulungisa of injectors kufanele kwenziwe uma kukhona zimpawu ezilandelayo: anda petrol kakhulu, behluleka uma thepha igesi isinyathelo, nophethiloli ukuvuza noma kokuphuma ohlelweni qeda. -Singles isivinini imoto engazinzile: inaliti tachometer njalo ukuthi "gxuma" ngaphandle kwesizathu. Ihlola Imibhobho esemzimbeni futhi ukulungisa yabo ukwenziwa zezitsha ekhethekile, ngakho-ke kunzima ukulungisa kubo ngokuzimela: ukusetha ingcindezi kwezingu-% 10 kuphela ngaphezu okuzisholo siyimbangela ukwehluleka in injini. Futhi ngisho noma umsebenzi kohlelo fuel akukuniki isizathu sokukhathazeka, injector ukuhlola - inqubo Kunconywa ngemva km 60 000-70 000 run izimoto.
