Ivalve yenaliti yesitofu samafutha ayivalwanga ngokuqinileyo ngomzimba wevalvu kwaye iyabanjwa
Iimpawu zokungaphumeleli: i-low-pressure oil circuit ayivaliwe, injini ye-diesel ijikeleziswa emva kokuba isibambo sokulawula isantya sibekwe kwindawo yokubonelela ngeoyile, isandi se-fuel injection ye-injector ye-fuel ayinakuviwa kwezinye iisilinda, kunye nomsi omhlophe. ikhutshwe kumbhobho wokukhupha, ngoko kunzima ukubamba umlilo.Xa i-injini ye-diesel ivutha, umbhobho wokukhupha ukhupha umsi, isantya sokuhamba asizinzanga, sikhatshwa sisandi esiphefumlayo esithi "Teng, Teng", kwaye kukho isandi esicacileyo sokunkqonkqoza ngesantya esiphezulu kunye ne-throttle.Xa ukushisa kwe-injini ye-diesel kuphakama, umbhobho wokukhupha ukhupha umsi omnyama, i-injector ye-fuel ishushu, kwaye umlilo "ulahlekelwa imilenze".Nqamula umbhobho we-oyile woxinzelelo oluphezulu lwe-cylinder yomlenze ongekhoyo.Umbhobho wokukhupha umoya we-injini ye-diesel awusakhuphi umsi, kwaye nesandi sokunkqonkqoza kombhobho siyanyamalala.Nangona kunjalo, kukho i-exhaust phenomenon kwi-high-pressure oil pipe joint ye-injector, kwaye i-foam iyakhutshwa.
Ukusilela uhlalutyo lwesizathu: (1) Ngexesha lenkqubo yokusebenza ye-injini ye-diesel, i-oyile ye-diesel yoxinzelelo oluphezulu empontshelwa ngaphandle kwimpompo yokutofa kwe-fuel ithwala ukungcola komatshini, ingene kwi-injector ye-fuel kwaye ibambelele kumphezulu wekhowuni yokutywina ye-valve yesivalo somzimba. , okubangela ukukhonkwana, ukugoba, kunye noqhagamshelwano Aluqinanga (2) Ngenxa yokukhutshwa kwegesi ephezulu yoxinzelelo kunye nobushushu obuphezulu kwigumbi lokutsha, kunye nokukhukuliseka rhoqo kokungcola komatshini kumafutha, imingxuma kunye nemingxuma ibonakala ekutywinweni. iringi phakathi kwevalve yenaliti kunye nomzimba wevalufa yenaliti, ebangela ivalve yenaliti kunye nevalve Umsebenzi wokutywina phakathi kwemizimba iwohloka, kwaye into eyenzekayo kukuba umthamo wokubuyisela i-oyile kumngxuma wokubuya kwe-oyile we-oyile uyenyuka.Ngale ndlela, i-high-pressure kunye ne-high-temperature gas kwigumbi lokutsha iya kungena kwigumbi le-oyile ye-annular ye-injector ngexesha lokusebenza.Ngaphantsi kwesenzo sobushushu obuphezulu, ivalve yenaliti yokutofa kunye nomzimba wevalvu ziyafudunyezwa kwaye zandise kwaye zilumane zide zife.(3) Kuninzi kakhulu ukungcola komatshini kwi-oyile ye-diesel, okuya kubangela ukuba ukungcola kungene phakathi kwevalve yenaliti kunye nomphezulu wesikhokelo somzimba wevalvu kunye nokuluma ukufa.Ngenxa yokuba ivalve yenaliti ye-injector ibambelele kumzimba wevalve, ukusebenza kwe-atomization yeoli ye-diesel kuyancipha, ixesha lokutofa kwe-fuel lifutshane kakhulu kwaye libuyela umva kancinci, okukhokelela kwisantya esifutshane kakhulu sokutshisa kunye nexesha lokutsha, elenza ukuba i-valve ye-injector ibambeke. I-injini ye-diesel isebenza rhabaxa, ngoko ke injini ye-diesel ikhupha " i-Teng, i-Teng isandi kunye nesandi esicacileyo se-cylinder esinkqonkqoza. Igesi yeqondo lokushisa kwigumbi lokutshisa ingena kwigumbi le-oyile ye-annular ye-injector, iya kubangela ukuba i-injector ibe shushu.Ukuba injini ye-diesel iguqulelwe kulo mbuso, umoya oxinzelelweyo owenziwe kwi-cylinder uya kungena kwigumbi le-oyile ye-annular kunye ne-oyile yokuhamba. ngomngxuma womlomo ovulekileyo, kwaye ukhutshwe kumbhobho we-oyile woxinzelelo oluphezulu, ngaloo ndlela ibonise ukukhutshelwa kombhobho we-oyile woxinzelelo oluphezulu.
