Pump-nozzle: gulu ndi kukonza

Chaka chilichonse kufunika kwa injini dizilo malinga ndi muyezo monga mphamvu, zachilengedwe ndi zachuma ndi kukula. Ndipo chabe mapangidwe wangwiro wa osakaniza flammable akhoza zinthu zimenezi. Choncho, dongosolo lonse la mafuta jekeseni ndi ntchito efficiently, kupereka mphindi sprayed pansi kuthamanga.

Chotero dongosolo, chomwe chili mu umodzi wagawo mafuta injector ndi mpope, mpope-atomizer. Mofananamo, kuthamanga mpope, mpope-injector injects wina kuchuluka kwa osakaniza pa nthawi yoyenera. Chifukwa chakuti aliyense wa zonenepa a injini pali wina wagawo injector, mu dongosolo palibe mpope mafuta jekeseni.

Zida nozzles monga mutu yamphamvu oyenerera dizilo wagawo injector. Kuwalowetsa mphamvu pa camshaft 4 ali ndi kamera wapadera. Mphamvu pa injectors plungers wagawo kamafalikira kudzera rocker lapansi. Chifukwa mbiri wapadera wa unit injector rocker kamera galimoto woyamba zikuchepa likutuluka, ndipo ndiye kugwa pang'onopang'ono.

Pa nthawi imene pali kuwuka kwake mkono rocker, plunger ndi mbamuikha ndi lalikulu liwiro pansi. Choncho, pali kuthamanga magazi. Pamene dzanja rocker wayamba kugwa pang'onopang'ono, ngati plunger Umayamba kusokoneza ndi yunifolomu kayendedwe oposa. Chotero kumanga pa zochitika mafuta kulowa kuthamanga chipinda bwino, popanda mapangidwe mpweya thovu. Nthawi ndi jekeseni ulamuliro solenoid vavu ulamuliro wagawo injector. Chifukwa chaichi, kudzera pakompyuta ulamuliro wagawo aziwapatsa voteji. Ngakhale zolakwika ang'onoang'ono magawo zomera amapezeka pa kutsitsi mafuta, injini akuyamba "phokoso."

Dizilo injector mpope angakhale mitundu itatu: piezoelectric, atomu, electrohydraulic. Ndi solenoid vavu nozzle ngati mafuta ndi dizilo injini, ndipo ali ndi dongosolo losavuta: pa nozzle ndi solenoid valavu ndi singano kutsitsi. The zamagetsi-injector waikidwa yekha injini dizilo, amene zambiri ntchito pa dongosolo Caumont Ryle. Piezoelectric ankaona zotsogola injini dizilo. Chotero unit injector kumayambika nthawi 4 mofulumira kuposa solenoid, ndipo Mlingo wa jekeseni mafuta molondola pazipita.

Kukonza injectors zizichitidwa pamene pali zizindikiro zotsatirazi: kuchuluka mafuta kwambiri, kulephera pomwe ndikupeza pa mpweya ngo, mafuta kutayikira kapena kumatuluka mu dongosolo utsi. Yekha galimoto liwiro wosakhazikika: ndi tachometer singano zonse "kudumpha" popanda chifukwa. Poona nozzles ndi kukonza awo amachitidwa pa nthandala wapadera, kotero n'zovuta kuzikonza paokha: atakhala ndi mavuto% 10 okha pamwamba mwadzina ndi chifukwa cha zolakwa za mu injini. Ndipo ngakhale ntchito ya dongosolo mafuta sapereka kalipokalipo, injector diagnostics - ndondomeko imene tikulimbikitsidwa iliyonse 60 000-70 000 Km wa athamangadi magalimoto.
