INozzle Yomjovo Omusha Kadizili Osezingeni Eliphezulu DLLA144P2273 0433172273 0 433 172 273 Imbobo Yomjovo Ovamile Wesitimela Wezingxenye Eziyisipele ze-Bosch

Inqubo yokuhlola i-fuel injector

Ukuhlolwa komhlangano we-valve yenaliti kuhlanganisa: ukuhlolwa okubonakalayo okungaphezulu, ukuhlolwa kokuslayida, ukuhlolwa kokuvala uphawu nokuhlola isifutho, njll.

3.1 Indawo eyisilinda engumhlahlandlela yevalvu yenaliti kanye nomzimba womjovo akumele kube nomonakalo osobala wokungqubuzana nokuklwebheka, futhi indawo yekhoni yokuvala iphelele.

3.2 Tshekisa i-valve yenaliti endaweni engu-45°, donsa ivalvu yenaliti iphume emzimbeni wevalvu cishe ngo-1/3, futhi ingashelela kancane ingene emzimbeni wevalvu ngaphansi kwesenzo sesisindo sayo ngaphandle kwanoma iyiphi into enamathelayo.

3.3 Faka umjovo kaphethiloli ohlanganisiwe kusihloli somjovo kaphethiloli, bese ulungisa umfutho wasentwasahlobo ube phezulu kancane kunomfutho wokuvula ojwayelekile womjovo kaphethiloli womjovo kaphethiloli (ngokuvamile u-12~14MPa ngaphezu kuka-3~5MPa). Uma umfutho kawoyela ukhuphukela ku-20MPa, linganisa isikhathi esisithathayo ukuze umfutho kawoyela wehle usuka ku-20MPa uye ku-18MPa, hhayi ngaphansi kuka-9~12s.

Uma kungenjalo, ukusebenza kokuvala kubi, futhi akumele kube namaconsi kawoyela asobala eduze kwembobo yombhobho. Uma singekho isihloli se-fuel injector, isitofu esikhandwayo somjovo singafakwa ngqo empompini yomjovo kaphethiloli yenjini ye-diesel ukuze sihlolwe.

3.4 Lungisa ingcindezi eshiwo yomjovo kaphethiloli engu-12MPa, bese umpompa uwoyela ngesivinini sepompo cishe izikhathi ezingama-60～70/min. Uphethiloli ofuthwe kufanele ucoliseke futhi ufane ne-athomu, futhi kube nemisindo yokutshiyoza eqabulayo nephakathi. Ayikho into econsisa uwoyela, futhi akukho ukuvuza okubucayi eduze kwembobo yembobo yomzimba womjovo.

Beka ucezu lwephepha elimhlophe eliqhele ngo-10 ~ 20cm ukusuka emlonyeni ngaphansi komjovo, bese ukala ibanga elingu-h ukusuka emlonyeni ukuya ebaleni likawoyela kanye nobubanzi d bebala likawoyela. Bese ubala ngokwefomula.

Thola i-engeli kusukela kumsebenzi we-trigonometric, futhi i-engeli ephindwe kabili i-engeli yekhoni yomjovo kaphethiloli. Uma izidingo zingakwazi ukufezwa ngalo msebenzi ongenhla, kufanele kushintshwe umjovo kaphethiloli omusha.

Okokugcina, amaphuzu alandelayo kufanele aqashelwe:

(1) Naka ikhodi engenhla lapho usebenzisa isijojo sikaphethiloli ukuze ugweme ukusisebenzisa kabi. Uma kungenjalo, izidingo ezifanelekile ngeke zitholakale, uphethiloli uzoshiswa ngokungaphelele noma ungashiswa, umusi omnyama uzokhishwa ku-exhaust, uphethiloli uzochithwa, futhi amandla azothinteka.

(2) Uma ulungisa ukucindezela komjovo kaphethiloli, ungalinge uvumele isikhumba noma iminwe isondele eduze kwembobo yombhobho bese ijovwa ngesibaseli esijovwe. Ngenxa yokuthi uwoyela we-diesel onengcindezi ephezulu ungena esikhunjeni futhi ugeleze emithanjeni yegazi, uzoba nomthelela onobuthi emzimbeni womuntu. Kufanele kuqashelwe ngokukhethekile ukuze ungalokothi ubukele isimo sokujova uphethiloli eduze kakhulu ukuvimbela ukulimala kwamehlo.
