0042 Isixhumi Esivaliwe I-LPG CNG Yokubuyisela Ikhoyili ye-Solenoid

Ikhoyili yevalvu ye-solenoid ingama-29mm ukuphakama no-9mm ububanzi bangaphakathi.
1. Izimo zokwahlulela izinsalela zekhoyili yokufafaza kaloliwe: Hlola ukuthi akukho yini ukuvuza komoya empandeni yezintambo zocingo nokuthi ukumelana kwamakhoyili amane kuphakathi kuka-9 no-3 ohms.

Okwesibili, umkhiqizo uhlanganiswe nezinto ze-thermoplastic noma i-flame retardant kanye ne-resin ukumelana nokushisa okuphezulu, enokumelana okuhle kakhulu nokushisa okuphezulu nokumelana nomswakama. Isetshenziswa kakhulu kusistimu yokufaka kabusha i-LPG/CNG yemoto, ujantshi ojwayelekile wegesi, idivayisi yesithuthuthu, kanye ne-voltage resistor DC12V.

III: ① Isakhiwo namapharamitha wobuchwepheshe womjovo ojwayelekile wesitimela

1, isakhiwo somumo

Isetshenziswa kakhulu kuma-injection kaphethiloli ezimoto ezithengiswayo, ezikwazi ukuthola amafomu amathathu omjovo: umjovo wangaphambili, umjovo omkhulu kanye nomjovo wangemuva. Ubuningi bomjovo kaphethiloli kanye nobude bomjovo kaphethiloli kunqunywa ingcindezi yesistimu namandla ngesikhathi, futhi kuqhutshwa iyunithi yokulawula ye-elekthronikhi. Njengamanje, ama-injection ezimoto ezithengiswayo ikakhulukazi akumafomu alandelayo;

2. Imingcele yezobuchwepheshe eyinhloko

Ukumelana nekhoyili: 230mΩ

Isikhathi esiphezulu samandla: 4ms

Ubukhulu bengcindezi yesitimela yokusebenza: 1600bar

② Umgomo wokusebenza womjovo wesitimela ovamile

isimiso sokusebenza

Vala (awukho umjovo) = > Vuliwe (qala umjovo) = > Ukuvuleka okugcwele (umjovo) = > Valiwe (ukuncipha komthamo womjovo) = > Ukuvala ngokugcwele (umjovo wokumisa)

③ Ukwehluleka okujwayelekile kwama-injection kaloliwe ajwayelekile kanye nezindlela zawo zokucwasa ngaphambilini.

1. Ukugqwala kwangaphakathi kukaphethiloli

njectorIzimpawu zeFault: injini isebenza kabi, futhi kukhishwa intuthu emnyama lapho kufakwa uphethiloli emnyango;

Imbangela yokwehluleka: amanzi amaningi kuphethiloli;

Isixazululo: 1. Qinisekisa izinga likaphethiloli; 2. Khipha amanzi njalo futhi uqinisekise ikhwalithi yesihlukanisi samanzi samafutha;

2. Indawo yokuhlala yangaphakathi yomjovo igqokile.

Isenzo sephutha: ukukhanya kwephutha kuvuliwe, umusi omnyama ukhishwa lapho umnyango wegesi ugcwaliswa, futhi amandla awanele;

Imbangela yokwehluleka: uphethiloli uqukethe inani elikhulu lezinhlayiya ezinhle;

Isixazululo: Qinisekisa ikhwalithi yesihlungi, ikakhulukazi ikhwalithi yokuhlunga okuhle. Faka idivayisi yokuhlunga embotsheni yokukhipha umoya yethangi likawoyela ukuze ugweme indawo yangaphandle ekungcoliseni uphethiloli futhi uqinisekise ikhwalithi yamafutha.

3, i-copper gasket seal ayilungile, i-cylinder gas channeling.

Izimpawu zephutha: amandla enjini anganele, igesi evuthayo ebalekela emafutheni abuyayo;

Isizathu sokwehluleka: i-gasket yethusi yayiboshwe yizinhlayiya futhi yayingakwazi ukuvaleka;

Isixazululo: Qinisekisa ukuhlanzeka kwe-gasket yethusi, imbobo yokufaka injini kanye nomjovo lapho ufaka i-injector.

I-gasket yethusi ayikwazi ukuphinda isetshenziswe. U-Bosch uncoma ukusebenzisa i-gasket eyodwa yethusi ukuze ugweme ukusebenzisa ama-gasket amaningi.

4, ukuncibilika kwekhoyili ye-electromagnetic valve electromagnetic

Uphawu lwephutha: i-injector ayikwazi ukusebenza ngokujwayelekile;

Imbangela yokwehluleka: ikhoyili ye-solenoid valve iyancibilika ngenxa yamandla kagesi aphezulu kakhulu noma isikhathi eside samandla;

Isixazululo: Akuvunyelwe ukufaka amandla ngokwenziwa komshini wokujova uphethiloli;

5, umonakalo owenziwe ngomshini

Uphawu lwephutha: Umjovo awukwazi ukusebenza ngokujwayelekile ngenxa yokulimala kwemishini, futhi injini ayizinzile.

Isizathu sokwehluleka: ukusebenza okungalungile nokufakwa okungenangqondo.

Isixazululo: 1. Qinisa isivalo sevalvu ye-solenoid, isiphetho kanye nepulaki yenqwaba ukuze ugweme ukusebenza kanzima; 2. Faka umjovo kaphethiloli ngokuhambisana ngokuqinile nencwadi yeziqondiso;

IV: Umdwebo wesakhiwo se-solenoid valve common rail injector
. I-valve ye-solenoid yokulawula yamanje iheha i-armature, futhi i-armature ishayela isiqu se-valve nombhangqwana wevalve yenaliti yokuvula umjovo kaphethiloli ukuze umjove uphethiloli.

Ngakho-ke, ukulawula i-injector kaphethiloli ukulawula i-valve ye-solenoid yesijojo sikaphethiloli. I-valve ye-solenoid ilingana nekhoyili, ekhiqiza amandla kazibuthe kagesi ngokudlula amandla kukhoyili. Uma umsinga mkhulu, amandla kazibuthe kagesi abe mkhulu kuze kube yilapho izikhali zingakhangwa. Ekusetshenzisweni okungokoqobo, i-injector ivamise ukuvulwa nge-current enkulu kuqala, bese i-valve ye-solenoid igcinwa nge-current ephansi.
