Rail Common - kuyini? Umgomo we operation

Eminyakeni yamuva, abashayeli abaningi bakhetha ukusebenzisa udizili izimoto. Ngaphambilini, le izinjini efakiwe kuphela izimoto kwezohwebo. Nokho, manje kabanzi izimoto ezithwala, ikakhulukazi e-Europe. Ngokuqinisekile ngamunye wethu ayezwile isimiso esinjalo, njengoba Common Rail. Kuyini futhi asebenze kanjani, esizoyicabangela kulesi sihloko.

sici

"Common Ryle" - uhlelo fuel injection ngoba udizili. isimiso sayo wokusebenza kusekelwe supply uphalafini injectors we ezivamile wesitimela ingcindezi. Uhlelo yasungulwa ngochwepheshe German inkampani "Bosch". Common Rail Bosch evame ukusetshenziswa izimoto ezifana "Volvo", "Mercedes", BMW nabanye.

Kuyini ekhethekile?

The main lolwehlukanisa uhlelo - ikhono ukunikeza amandla oyifunayo ne ubuncane petrol. Common Rail fuel futhi kungaba ukunciphisa izinga qeda kwekhabhoni. Izibuyekezo abashayeli bathi imoto nge fuel uhlelo lomjovo ethulile kakhulu (akukho 'uyabhonga "enjalo isici, efana diesel ubudala). "Common Rail" has a ezahlukene ingcindezi isiqondiso nophethiloli umjovo isiqalo zikhathi.

kudivayisi

Le miklamo Common Rail uhlelo wesifunda ephezulu ingcindezi. Lapho injini Kwenziwa umjovo oqondile uphethiloli (ngamanye amazwi, nophethiloli ihlinzekwa ngqo ekamelweni isilinda). Kukhona izakhi eziningana ezihlobene umsebenzi Common Rail uhlelo. Yiziphi lezi zingxenye? Eyokuqala i umfutho ophakeme fuel futha. It is libuye lisetshenziswe valve nokushintsha kokudla nokufakwa kanye somthetho ingcindezi. Ngaphezu kwalokho, kukhona fuel ujantshi injector design. Rail Common - uhlelo kunalokho eyinkimbinkimbi ukuqonda ukusebenza yayo isimiso, cabangela izici ingxenye ngayinye.

futha

Ngakho, ophezulu futha. Le ndlela yokwenza isetshenziswa ukudala i ophezulu uketshezi. Level incike injini umthwalo futhi ngomzuzu we crankshaft. Njengoba wazi, isivinini diesel kungukuthi kulawulwa kuvulwa valve mpintsha, okungukuthi ingxenye fuel kokuba enikeziwe. Ukuze lokhu, lihlangabezana lo ophezulu futha. Idivayisi kuyinto kunalokho eziyinkimbinkimbi, ngakho lapho lesi sakhi - ingxenye eqolo imoto udizili (phezu, ngaphandle Izingxenye eziyisisekelo, ezifana yangaphakathi omlilo izinjini kanye PPC).

Regulator kanye valve Common Rail

Kuyini lokhu isici? Valve isetshenziswa ukulawula inani uphethiloli yanikezwa futha. timphawu tesakhiwo ngokuhlanganiswa futha. Kukhona Regulator fuel ingcindezi. It efakwe kule wesitimela fuel, futhi ilawula motor kuye komthwalo wayo.

limes

Le yunithi wenza imisebenzi eminingana. Lokhu ukuqongelela fuel ngaphansi kwengcindezi okusezingeni eliphezulu ukunciphisa ingcindezi oscillations nophethiloli ukusatshalaliswa Imibhobho esemzimbeni. Kuyinto yesimiso eyanele.

Imibhobho esemzimbeni

Kuyaphawuleka ukuthi labo ezibekwa njengoba uphethiloli (injector), kanye diesel. Nokho, umehluko yabo eyinhloko - kungcono ingcindezi ukuthi ukudala. Kulokhu injector "Common Rail" futhi ilawula inani uphethiloli sidla ngqo uMbhalo. I element ixhunyiwe ngqo kummango. Okwamanje, izinhlobo ezimbili ezahlukene Imibhobho esemzimbeni:

• I injectors Piezo ( "Bosch").
• Electro (umkhiqizi main - "Delfi").

Kulo mBhalo, the supply fuel kuveza ukusebenza kwe -valve Solenoid. I injectors Piezo banesibopho lokhu zinhlayiya ekhethekile. Ijubane lezi zinto iphezulu kakhulu, ngakho kuvamile. Nokho, ukukhanda Common Rail (Jets) ukukhiqiza izandla zabo akunakwenzeka ngenxa yokuba yinkimbinkimbi design futhi ukuhleleka kwayo. Ngakho-ke, wonke umsebenzi yesondlo ohlelweni abazenzi kuphela eziteshini ezikhethekile. Lona ethile eyinhloko izimoto anjalo.

Isebenza kanjani?

Umsebenzi ilawulwa udizili umjovo elawula uhlelo uhlelo. Okwamuva zihlanganisa actuators, izinzwa ECU. Ikhumbula zonke imingcele - isikhundla namafutha, izinga lokushisa Isibandisi, inani emoyeni ngisho ukubunjwa amagesi qeda (uphenyo lambda). Mayelana the actuators, zingabantu oshiwo ngenhla umlomo wombhobho kummango, nophethiloli futha, Umlawuli valve. Ngakho, indlela uhlelo lusebenza? Ngokusekelwe amasignali ukuthi ukulawula izinzwa okucatshangelwayo uhlelo kwakhiwa ngenani elithandekayo nophethiloli. It is fed nge valve metering. Okokhelekayo ifinyelela futha, bese ingcindezi ukhuphuka kummango. Ingcindezi angadingeki agcinwayo Regulator ekhethekile. Ngesinye isikhathi esededelwe, computer ithola isiginali kusuka injectors, nalabo lwenziwa kuvulwa iziteshi inkathi ethile yesikhathi. Kuye mode wokusebenza yenjini, nophethiloli ingcindezi ngokuzenzakalela Ungashintsha uhlelo ngesisekelo idatha kusuka inzwa umoya-mpilo. Nokho, run kufanele kube encane. ngeziphambeko Obalulekile ukhombise amaphutha kanye "Common Rail" uhlelo.

Izinhlobo umjovo Common Rail

Kuyini lokhu? Kunezinhlobo eziningana fuel injection ohlelweni:

• Olwandulelayo.
• Main.
• Akuphoqelekile.

Eyokuqala senzeka phambi eyinhloko ukuze kwandise ingcindezi yokufuna futhi izinga lokushisa ekamelweni amandla omlilo. Ngakho eyenziwa autoignition esasizosheshisa icala main futhi ukwehlisa umsindo injini. Oku-umjovo zingase zihluke, kuye ngesimo injini yokusebenza. Ngakho, ngo-kokungenzi lutho ukuthi likhiqizwa kabili. Njengoba kwanda umthwalo - kanye. pre-umjovo ayisetshenziswa at umthwalo omningi. Injongo umjovo main - ngqo ukunikeza injini. Subtypes, akakhulumi ihlukaniswe. umjovo engeziwe kusiza ekunciphiseni qeda amagesi ubuthi. Ngakho, kusukela ngo-inzwa-mpilo uthola ulwazi kwi-computer, bese enikeziwe kwenye ingxenye nophethiloli. izinto ezilimazayo afterburned e ekwandeni (kungcono futhi ngokuthi esebenzisa udizili particulate ukuhlunga).

Generation "Common Rail"

Kuyaphawuleka ukuthi isizukulwane sokuqala uhlelo uvele ngonyaka 1999. It ingcindezi okukhipha 145 MPA. ngemva kweminyaka emibili kwafika uhlelo isizukulwane esilandelayo (160 MPA). 3 Common Rail ithuthukiswe ngonyaka 2005. Okwamanje, izimoto anemisila isimiso "Common Rail" kwesizukulwane sesine. I Imibhobho esemzimbeni sokuqhuba ukucindezela 220 MPA. Kungani kangaka abayinakanga ingcindezi? Ayanda score, uphethiloli ngaphezulu injected uMbhalo. Ngakho, isikhathi esithile it is baqaphela ngokwengeziwe amandla inyuka injini kahle.

isiphetho

Ngakho, lapho sathola khona ukuthi ngqo umjovo uhlelo, it is indlela okuhlelwa futhi ukuthi isebenza kanjani. Kuyaphawuleka ukuthi "Common Rail" isetshenziswa izimoto kakhulu diesel, ikakhulukazi e-Europe. Uhlelo, naphezu yinkimbinkimbi kwako isethubeni elikhulu.
