Rail Common - waa maxay? Mabda 'hawlgalka

Sanadihii la soo dhaafay, darawallada iyo aad u badan waxay door bidaan in ay isticmaalaan baabuurta naaftada. Markii hore, matoorrada, kuwaas oo loo xiraa kaliya on baabuurta ganacsiga. Si kastaba ha ahaatee, ay hadda si weyn loo isticmaalaa in baabuurta rakaabka, gaar ahaan Yurub. Waxa hubaal ah in mid kasta oo inaga mid ah ka maqlay nidaamka noocan oo kale ah, sida Rail Common. Waa maxay iyo sida uu u shaqeeyo, in aan tixgelin doonna in this article.

feature

"Common Ryle" - nidaamka duro shidaalka ah engine naaftada. Its mabda 'ee hawlgalka ku salaysan yahay sahayda shidaalka u injectors ee cadaadiska rail caadi ah. Nidaamka waxaa la sameeyey by khubaro Jarmal ee shirkadda "Bosch". Common Rail Bosch waxaa caadi loo isticmaalaa in gaadiidka sida "Volvo", "Mercedes", BMW iyo kuwa kale.

Waa maxay gaarka ah?

feature ugu muhiimsan ee lagu garan nidaamka - awood u leh inay siiyaan awood la doonayo taagdarro shidaal yaraan. shidaalka Rail Common sidoo kale hoos u dhigi karaa heerka qiiqa dhammayn. Reviews of darawallada ayaa sheegaya in baabuur la isku duro nidaamka shidaalka ah waa badan aamusan (ma sifo "guuxeen" sida, sida matoorada naaftada jir). "Common Rail" ayaa tiro balaadhan oo ah xeerka cadaadiska iyo shidaalka duro bilowday daqiiqado.

qalab

The naqshado nidaamka Common Rail waa circuit-kar ah. Marka engine ah waa la fuliyay duray si toos ah shidaalka (i.e., shidaalka si toos ah bixisey galay qolkii dhululubo ah). Waxaa jira dhowr cunsur in xiriirka la leh shaqada ee nidaamka Common Rail. Maxay yihiin qaybaha kuwanu? Ka hore waa bamka shidaalka saaran yahay cadaadis sare. Waxaa sidoo kale loo isticmaalaa in waalka kacmaha iyo jaangooyaha cadaadis ah. Intaa waxaa dheer, waxaa jira design rail shidaalka iyo Injector ah. Rail Common - nidaam halkii adag, iyo in la fahmo mabda shaqada ay, tixgeli sifooyinka ah ee qayb kasta.

bamka

Sayidka, bamka cadaadis sare. farsamo waxaa loo isticmaalaa si ay u abuuraan cadaadis sare dheecaanka. Heerka ku xiran tahay load engine iyo rpm of crankshaft ah. Sida aad ogtahay, matoorada naaftada xawaaraha ku jira lama ilaaliyo by furitaanka waalka ceejinta ah, kuwaas oo qayb ka mid ah shidaalka la bixisey. Waayo, kanu, oo ay la kulanto bamka cadaadis sare. Qalabka wuxuu u yahay halkii u adag, sidaas element this - qayb ugu qaalisan baabuurta naaftada ah (in ka badan, marka laga reebo unugyada aasaasiga ah, sida matoorada sari gudaha iyo PPC).

Jaangooyaha iyo waalka Common Rail

Waa maxay element this? waalka waxaa loo isticmaalaa si loo xakameeyo lacagta shidaalka bixisey in bamka. xubno Dhismayaasha weheliso bamka. Waxa kale oo jira jaangooyaha cadaadis shidaalka ah. Waxaa loo xiraa in tareenka shidaalka, oo ay gacanta ku motor ku xiran ay load.

Nuurad

Cutubkan waxa ku qabata dhowr hawlood. Tani raasamaal shidaalka hoos oscillations cadaadis ah aya cadaadiska sare iyo nozzles qaybinta shidaalka. Waa qayb ka mid ah nidaamka qaadashada waa.

nozzles

Waxaa xusid mudan in kuwa lagu wadaa sida baatrool (Injector), iyo matoorada naaftada. Si kastaba ha ahaatee, ay kala duwan yihiin ugu weyn - waa cadaadis in ay abuuraan. In Injector kiiskan "Common Rail" ayaa sidoo kale gacanta ku cadadka shidaalka ee si toos ah quudiyey galay dhululubo ah. element waxaa toos ah ugu xiran sagxada ah. Waqtigan xaadirka ah, oo laba nooc oo kala duwan oo nozzles:

• injectors piezo The ( "Bosch").
• Korontada (soo saare ugu weyn ee - "Delfi").

Xaalada danbe, sahayda shidaalka waxaa soo saaray hawlgalka waalka solenoid. injectors piezo ayaa ka mas'uul ah this kiristaalo gaar ah. xawaaraha walxahaasi waa badan, si ay u badan yihiin. Si kastaba ha ahaatee, dayactirka ee Common Rail (Diyaaradaha) in ay soo saaraan gacmaha iyaga u gaar ah suurtogal ma aha sabab u ah dhibka ka mid ah design iyo daafigaw wanaagsan. Sidaa darteed, dhammaan shaqo dayactir ah oo ku saabsan nidaamka la fuliyaa oo keliya saldhigyada gaar ah. Tani waa khasaare ugu weyn ee gaadiidka sida.

Sidee u shaqeeyaan?

Work waxaa ay gacanta ku habka nidaamka duro naaftada gacanta. ugu dambeeyay waxaa ka mid ah actuators, dareemayaal iyo ECU. Iyada oo la tixgelinayo kasta oo lagu cabbiro - jago ee xawaaraha, heerkulka coolant ah, lacagta hawada iyo xitaa ka kooban of gaasas qaaca (baaritaan lambda a). Marka la eego actuators ah, ay yihiin kor ku xusan sagxada biiyaha, bamka shidaalka, jaangooyaha iyo khaanadaha. Sidaas, sida nidaamku u shaqeeyo? Iyada oo ku saleysan signalada kontoroola ah dareemayaal gartay, nidaam sameeyay lacagta la doonayo shidaalka. Waxaa lagu quudin jiray iyada oo waalka Electricity-ka. Shiidaalka gaadho bamka, ka dibna cadaadis kor u kaco sagxada ah. cadaadis loo baahan yahay in jaangooyaha ku ceshan gaar ah. Halkaa marka ay marayso qaar ka mid ah, computer helo signal ka injectors ah, iyo kuwa sameeyaa furitaanka channels muddo waqti go'an. Iyada oo ku xidhan habka hawlgalka ee engine ah, iyo cadaadiska shidaalka si toos ah bedeli kartaa habka ku saleysan xogta laga shidma oxygen ah. Si kastaba ha ahaatee, orod waa in ay ahaataa yar yar. leexashooyinkaasi weyn ayaa tilmaamaya unu la nidaamka "Common Rail".

Noocyada duro Common Rail

Waa maxay? Waxaa jira dhawr nooc oo isku duro shidaalka ee nidaamka:

• Hordhaca ah.
• Main.
• Ikhtiyaar.

Midkii kowaad wuxuu dhacaa ka hor inta aasaasiga ah si ay u kordhiyaan u cadaadiska iyo heerkulka ahaa qolladdiisii oo ku sari. Sidaas qaadeen autoignition dedejiyey kharash ugu weyn iyo yaraynta qaylada engine. Pre-duro waxaa laga yaabaa kala duwan, taas oo ku xidhan xaaladiisu engine ah. Sidaas darteed, at ula taagtaagan waxaa la soo saaray laba jeer. Iyada oo sii kordhaya load - mar. pre-duro aan la fulin at load buuxa. Ujeedada ugu weyn ee laga muday - si toos ah u siiyaan engine ah. Nooc hoosaad, waxa uu lama kala. duro dheeraad ah u adeegta si loo yareeyo gaasas dhammayn sumoobo. Sidaas darteed, tan iyo shidma ogsijiin helo macluumaad ku saabsan computer ka, ka dibna bixisey in qayb kale oo ka mid ah shidaalka. waxyaabo waxyeello afterburned in Hannaan ah (waxaa kaloo loo yaqaan filter naaftada particulate a).

Generation "Common Rail"

Waxaa xusid mudan in jiilka koowaad ee nidaamka u muuqday sanadkii 1999 sano. Waa cadaadiska wax soo saarka ee 145 MPA. Laba sano ka dib yimid nidaamka jiilka soo socda (160 MPA). 3 Common Rail horumariyo 2005 sano. Waqtigan xaadirka ah, baabuurta waxay leeyihiin nidaam "Common Rail" qarniga afraad. nozzles The shaqeeyaan at cadaadis ka mid ah 220 MPA. Waa maxay sababta aad u badan dareenka bixisay in cadaadiska? The sare score ah, shidaalka ayaa in ka badan waxaa lagu duraa dhululubo ah. Iyadoo la raacayo, muddo waqti go'an waxaa la ogaaday awood dheeraad ah korodhka oolnimada engine.

gunaanad

Sidaas daraaddeed, waxaan ka helay waxa nidaamka si toos ah isku duro, sida loo diyaarin iyo sida ay u shaqayso. Waxaa xusid mudan in "Common Rail" waxaa loo isticmaalaa in baabuurta naaftada ugu, gaar ahaan Yurub. Nidaamka, in kasta oo ay kakanaanta, ay leedahay awood weyn.
