Taraiwa pūnaha wahie engine i te ki Z. Scheme pūnaha wahie o te pūkaha diesel me te pūkaha penehīni

pūnaha Fuel - he konga mahu'inga o tetahi motokā hou. Ko whakarato reira te ahua o te wahie i roto i te ipurau pūkaha. Na reira, whakaaro te wahie e tetahi o nga wae matua o te hoahoa mīhini katoa. I roto i te te i teie mahana hoahoa tuhinga o te pūnaha wahie ka kia whakaaro, tona hanganga me mahi.

whakarite

Ko te mahi matua o tenei wae ko ki te homai i te ngingiha pūkaha ā-he nui etahi o te wahie. I mua i te reira i mua i haere te reira i roto i te maha o ngā kaupae purenga me te whangai i roto i te puoto pressurized.

pūrere kōpuku

Oddly nui, engari te kaupapa o te pūnaha wahie pūkaha diesel ko te tino rite ki ritenga penehīni. Ko te rerekētanga anake i waenganui ia ratou takoto i roto i te pūnaha werohia. Ko atu i runga i taua i muri mai, engari mo inaianei kia titiro a ki te hoahoa o te pae.

Ko te kupu, presupposes te kaupapa pūnaha wahie te oraraa o te huānga hoahoa e whai ake nei:

• Ko te tank hau. Ka taea te hangaia i tēnei huānga i te whārangi maitai ranei i te polypropylene rawa mātotoru. I roto i te waka pāhihi me atu-ara wahie tank eke i runga i te raro. I roto i te waka utanga, i roto i ngā tarakihana, kua titia reira ki te tautoko motuhake i waenganui i te auri muri, me te mua (mahue matau ranei). Ko te tank wahie he piha ārai wahie matamua atahanga o te waka.
• Filler pōtae. Tenei tūemi kua he miro motuhake, e āhei te kokoru rangi i tona hono vete '. Otiia ki te kaiarataki i reira watea ki te tango i te potae ki runga te mea i te whainiho motuhake. Ano hoki tenei huānga kua he piha haumaru e, ka tomo te waka i roto i te pēhanga tamarū i hokohoko aituā i roto i te tank. Ratau, i roto i te mīhini hou ki exhausts paerewa "Euro-2" me te ake tomo ki o wahie kohu ki te huru e kore e tukua. Na reira, ki te hopu i a ratou i roto i tāuta i te pūnaha te he adsorber waro motuhake.
• papu Fuel. Tenei huānga he puku hiko me te kei roto te tank. whakahaere te papu te wae mana hiko. I roto i te whakautu ki te kōrero i homai e te tānga motuhake. A, no te tahuri te taraiwa te ON pātīmata, mahi reira he tetahi wa (kaua e neke atu i te 4-5 hēkona), reira whakarato te pēhanga e hiahiatia ana i roto i te pūnaha ki te tīmata i te pūkaha. utu te tuhituhi hoki ko e te matao o te papu te penehīni. Na reira, mahi ana ki te tank kau kia tūkino reira.
• tātari Fuel. E mea pinepine, rite rawa te motokā i te rua ngā momo o ngā huānga raraunga. Tenei tikanga o pai, me te makaka combustible. Ko te strainer eke i runga i te whare wahie papu. Ko te ngako o tona mahi takoto i roto i te manawapa ki o paranga e kia tomo te pūkaha me te hanga i ngarahu te taikaha. Ano, te tātari tautururaa tino whakapiki i te ora whakahaere, te ārai i te reira i te contamination auau. Kei tikanga horoi pai i runga i te raro o te tinana, e anga te whakatārewatanga waka muri. hāngai ana tēnei momo o te tātari te i runga i te huānga pepa i te mea nehenehe ki te pupuri matūriki paru, uku me te waipara, e taea e tūkino i te pūnaha wahie.

taumata wahie pūoko

Kei te takoto te reira i runga i te kōwae papu. Na roto i te hoahoa, te pūoko taumata wahie ko te pūnaha iti arā, o te manu, me te tāupe tikanga resistance whakapā ki nairona. Tei runga i te maha o tirotiro i te tank wahie, te parenga o te huringa huānga, e ata te ngira i roto i te rōpū mauhaa i roto i te piha. Me kï reira e kore te e raruraru te pūoko wahie i te kounga rawakore o tāpiritanga wahie, me te kore e whatiia, ka auau huringa pāmahana me te pēhanga i roto i te tank.

poporo

Kei tēnei huānga o wha nozzles, ia o nei he kōmata whakaratohia. tāuta te rōnaki te i te maha horomanga, a ka mahi i te mahi o te supply wahie ki ia rango.

nozzles

Ko tenei taipitopito o faufaa ngā mo te waka, mai i tei reira ki runga ki te āhua o te kounga o te parariraa o te ranunga wahie-rangi, me te kohi mana o te waka. Ko te pupuha ko te tikanga iti ki te piha solenoid. Whakamutunga te mana e te ECU. A, no te faaue i te kōwae mana te supply mana ki te pupuha awhiowhio te, oroko piha pōro katia me rere te wahie i roto i te nebulizers pereti pupuha. Ratau, He rua e kua whakamahia ki te whakatika i te kohi wahie te pereti. Kei te patia Fuel ki te hongere pupuha o te maha vaolo kokoru. Nō reira, evaporates reira i mua i tomo i te ruma ngingiha.

Ko nga momo o ngā pūnaha wahie tuku

Ki te rā, ki te wehewehe i waenganui i te maha momo o ngā pūnaha wahie, e kua whakamahia i roto i te diesel me penehīni engines. I roto i ngā, e tahuri iho atu te pūnaha wahie supply pūkaha ngingiha ā-penehīni ki e rua momo me kia he Carburetor injector ranei. momo rua i ratou rerekētanga i roto i te hoahoa me te mahi.

Āhuatanga Carburetor

Ko o smeseobrazovatelya rawa te rerekētanga matua o tenei pūnaha i te injector wahie. Ingoa ia - te Carburetor. Tenei ko te wahi i reira ko te faaineineraa o te ranunga wahie-rangi. Kia anga te Carburetor i runga i te maha horomanga. Ki reira he wahie whangai te maputia e te i roto i te heke mai i te tikanga o seti me hanumi ki te rangi. Kei te whangai te ranunga oti ki te maha i roto i te piha kātere. Ko te tūranga o te muri, tei runga i te taumata o te kawenga pūkaha me te maha o ona takaí. Ratau, whakaaturia te wahie supply hoahoa pūnaha o te pūkaha penehīni te i roto i te pikitia i raro nei:

Ka rite ki a koutou e taea te kite, i roto i te akoranga o te ranunga faaineineraa me parariraa wahie whakahohe te pera maha pūoko hiko. O te faufaa ngā mo te waka tohu te pūoko tūnga kātere me nga huringa kawau hake.

Kia mōhio hoki e te ara iahiko pūnaha wahie (UAZ "taro" tae atu) te momo hāhira rerekē te taumata pēhanga iti, i hanga nei e i roto i te werohanga o te wahie. Ko te penehīni supply rawa ano ki te ipurau pūkaha whakamana e mahara, i.e. i tukupu te pēhanga i roto i te ruma parariraa i roto i te whakawhitinga o te kōkeke i BDC.

Āhuatanga o te injector

pūnaha wahie Scheme ( "Mercedes E200" tae atu) momo werohia he rerekētanga taketake i te Carburetor tairitenga:

• Tuatahi, ko te tank wahie e tukua ai ki te rōnaki, e kua hono ki te pupuha te rehu.
• Tuarua, tukua te rangi i roto i te ruma ngingiha pūkaha te roto i te pūrere kātere motuhake.
• A toru, te taumata o te pēhanga hangaia e te papu i roto i te pūnaha, i ngā wā atu i te e hanga Carburetor tikanga. faataa tēnei āhuatanga e te hiahia ki te whakarite wahie nohopuku werohanga pupuha ki te ruma ngingiha.

Otiia e kore e anake te mea rerekē i te pūnaha Carburetor wahie i werohia tenei. "Chevrolet Niva" (hoahoa o tona wahie tohua i roto i te whakaahua i raro nei), me te tahi atu waka hou, kua ki tona tikanga te pera-ka karanga "roro hiko", e ko te ki te mea ECU. Last kawenga mō te kohi me te tukatuka mōhiohio i pūoko ngā katoa i roto i te motokā.

Na, whakahaere hoki i te ECU wahie i werohia. Tei runga i te aratau o te hikohiko whakatau te aha kia whangai ahua o ranunga ki te rango - rawakore whai taonga ranei. Otiia e kore e anake tenei hoahoa rerekē pūnaha wahie ( "Ford Transit» CDi tae) momo werohia. kia whai te reira i te maha rerekē o nozzles. Ka tenei kia kōrero i roto i te wāhanga o muri.

Scheme werohanga wahie i te waka i werohia

Ki te rā, i reira e rua ngā momo o ngā pūnaha werohia:

• Monovpryskovye.
• Ki te werohanga maha.

I roto i te take tuatahi, ko te supply wahie ki ipurau katoa te meatia e te whakamahi i kotahi pupuha. I tenei wāhi e whakauaua pūnaha monovpryskovye whakamahia i roto i waka hou, e kore e taea te mea e pā ana ki ngā waka ki te werohanga tohaina. Āhuatanga o taua injectors ko e mo ia rango whakaturia ona ake, pupuha takitahi. Ko te tino pono tenei hoahoa tāutanga, engari no te mea kei te whakamahia ia e te automakers hou katoa.

Nahea te injector?

Ko te parau tumu o tenei pūnaha ko tino māmā. whangai Fuel i te tank i te papu e ki whakakorekore (reira he tonu wahie i te pēhanga teitei). Next haere reira ki te injector, i roto i nei te maputia ki te ruma ngingiha. Me kï reira e kore te mea pūmau, me i etahi wā te werohanga. I te wa ano te supply o wahie i roto i te rangi tomo te pūnaha. Kia puta te hanganga ranunga wahie i roto i te tetahi rahi, tomo te reira i te ruma ngingiha. Tukanga mō te faaineine i te ranunga o injectors e rave rahi taime tere atu i engines penehīni. mōhio hoki e te mahi o te riringi nozzles whakahaere he maha o pūoko atu. Anake ratou tohu te wae mana hiko whakahau te werohanga wahie. Ka rite ki a koutou e taea te kite, he rerekē i te Carburetor te pūnaha iahiko werohia-momo wahie. Tuatahi o te katoa, i reira he nozzles motuhake e rave nei i roto i te wahie i werohia ki te ruma ngingiha. A atu, pera i roto i waka penehīni, me te plug mura tahuri i runga i te huringa ngingiha kawea i roto i, ka ko e tahuri ki te patu kōkeke.

pūnaha peia o te wahie pūkaha diesel

He ona ake āhuatanga pūkaha diesel pūnaha wahie supply. Tuatahi, kawea te supply wahie ki te ruma ngingiha i roto i raro i pupuha pēhanga rahi. Mau, e tika ana ki tenei, tahuna te ranunga i roto i te ipurau. I te taua engines werohanga ranunga i marama e te tikanga o te mura i hanga e te plug korakora. Tuarua, ko te pēhanga i roto i te pūnaha hanga he papu wahie (nui-pēhanga wahie papu).

Ko, te ara iahiko pūnaha wahie (MAZ KamAZov me tae atu) he taua e kotahi rua naos whakamahia mō te werohia. Kotahi pēhanga iti, te tuarua - tiketike. Origin (i huaina ano hoki Priming) Kei te tuku wahie i te tank me te whai wāhi tika te supply wahie tuarua i roto i te injector.

Kei raro ko te hoahoa o te pūnaha wahie (KamAz 5320):

Ka rite ki a koutou e taea te kite, whakamahia e te reira i te rota atu āhuatanga atu waka penehīni. E te ara, i runga i te tahi mau putanga o engines KAMAZ te ato'a tāuta te turbocharger. Ko te whakamutunga te mauria i te mahi o te whakaiti tukunga whakapau me i te wa ano e faarahi te katoa te kaha o te pūkaha ngingiha ā-. he kaupapa pērā o te pūnaha wahie (KamAz 5320-5410) taea te wahie patia i te pēhanga teitei. I roto i tenei take, tonu te tapeke kohi wahie i te taumata kotahi.

te hātepe

Ko te parau tumu o te mahi o ngā pūnaha diesel, he maha hōhonutanga, pērā i te injector. pūnaha wahie Scheme ( "Ford Transit» TDI) pērā e te wahie mā te whakamahi i te papu kai haere i roto i te tātari pai, ka whangai ki te papu i werohia. Reira te reira i raro i te pēhanga nui e haere nei te injector kei roto i te upoko puoto. I te taime tika, kua whakatuwheratia te huarahi, a ka puta ranunga wahie ka maputia i te ruma, tukua nei takirere te mā te rangi motuhake mua-tuku. hoki hoki te wahi i te taikaha o te diesel wahie papu i werohia me pupuha ki te tank (engari e kore e roto i te tātari, me i hongere motuhake - korere Reflux). Ko te kupu, Ko uaua ake te hoahoa pūnaha wahie o te pūkaha diesel me titau atu pū i roto i te faaineineraa o te ranunga combustible. Fakatatau ki ai, he teitei ake i mo te hanga o te werohia taua utu tiaki engines.

mutunga

Heoi puta ngā matou i roto ano he hoahoa o te pūnaha wahie o te pūkaha diesel me penehīni aha titiro reira. Ka rite ki a koutou e taea te kite, e kore e te pūrere kōpuku raraunga rerekē i ia atu, ki te kahore hoki te momo o te wahie papu. Heoi, ahakoa o aha te kaupapa o te pūnaha wahie, he iti rawa te wa o te faaineineraa o te ranunga wahie i roto i te waka hou. Na reira, Me mahi tika, me te pai ngā tikanga katoa rite taea, no te mea e taea e te Rauna iti i roto i to ratou taumahinga meinga tahunga pāhiwihiwi o te wahie, me te arā o te pūkaha ngingiha ā-.
