Rail Common - he aha te mea te reira? parau tumu o te mahi

I roto i nga tau tata nei, hiahia ake me te ake kaitaraiwa ki te whakamahi i waka diesel. I mua, kua tāutatia enei motors anake i runga i waka arumoni. Heoi, kei te inaianei whānui e whakamahia ana e ratou i roto i waka pāhihi, rawa i roto i Europe. Pono i rongo ia o tatou o te pūnaha taua, pera i te Common Rail. He aha te mea me pehea e mahi i te reira, whakaaro tatou i roto i tenei tuhinga.

āhuatanga

"Common Ryle" - he pūnaha wahie werohia hoki engine diesel. hāngai Ko tōna parau tumu o te mahi i runga i te supply o wahie ki te injectors o te pēhanga tereina noa. I whakawhanakehia e te pūnaha e tohunga Tiamana o te kamupene "Bosch". Common Rail Bosch kei te whakamahia i roto i taua waka kia rite ki "Volvo", "Mercedes", BMW me etahi atu.

He aha te mea motuhake?

Ko te āhuatanga matua o te pūnaha - te kaha ki te hoatu i te mana e hiahiatia ana ki te kohi wahie iti. wahie Rail Common taea whakaiti hoki te taumata o te pira whakapau. Reviews o kaitaraiwa mea e te motokā ki te pūnaha werohia wahie he nui Ingarangi (kahore taua āhuatanga "haruru", rite engines diesel tawhito). "Common Rail" kua he whānui o te pēhanga ture me te wahie tīmatanga werohia taime ngā.

pūrere

Ko nga whakaaro o te pūnaha Common Rail ko te taiawhio nui-pēhanga. A, no te kawea te pūkaha i roto i te werohanga tika o te wahie (i.e., tukua wahie te tika ki te ruma rango). He maha ngā āhuatanga e kua e pā ana ki te mahi o te pūnaha Common Rail. He aha e enei wae? Ko te tuatahi ko te wahie papu pēhanga teitei. Kei te whakamahia hoki te reira i roto i te piha dosing me te regulator pēhanga. I tua atu, i reira ko te wahie tereina me te injector hoahoa. Rail Common - he pūnaha kaua uaua, me ki matau ona parau tumu mahi, whakaaro nga āhuatanga o ia wae.

papu

Ko te kupu, ko te papu pēhanga teitei. whakamahia ana tēnei tikanga te ki te waihanga i tētahi pēhanga teitei inu. Tei Taumata runga kawenga pūkaha me te rpm o te kawau hake. Ka rite ki matau koutou, e kore e engines tere diesel whakaritea e te whakatuwheratanga o te piha kātere, ara te tukua te wahi o te wahie. Hoki tenei, a ka tutaki te reira i te papu pēhanga teitei. Ko te pūrere kaua uaua, na tenei huānga - te wāhanga tino utu i roto i te motokā diesel (runga, nga wae taketake, pērā i engines ngingiha ā-me te PPC anake).

Regulator me takirere Common Rail

He aha te mea tenei āhuatanga? whakamahia te takirere te ki te whakahaere i te nui o te wahie tukua ki te papu. āhuatanga hanganga ngā ki te papu. He he ano hoki te regulator pēhanga wahie. Kei te tāuta i te reira i roto i te tereina wahie, a ka whakahaere te pūkaha i runga i tona kawenga rānei.

poporo

Tenei kōwae mahi e rave rahi mahi. Tenei haaputuputuraa o te wahie i raro i pēhanga teitei oscillations pēhanga mitigating me nozzles wahie tohatoha. Ko reira wahi o te pūnaha horomanga.

nozzles

E tano ia tapao e whakaturia te hunga e rite penehīni (injector), me hoki engines diesel. Heoi, ratou rerekētanga matua - te reira te pēhanga e hanga e ratou. I roto i tenei injector take "Common Rail" whakahaere ano te nui o te wahie whangai e te tika ki te puoto. hono te huānga kei te hāngai ki te rōnaki. I te kau, e rua rerekē momo o nozzles:

• Ko te injectors piezo ( "Bosch").
• Electro (te kaihanga matua - "Delfi").

I roto i te take whakamutunga, whakaputaina te supply wahie e te mahi o te piha solenoid. He kawenga mō tenei tioata motuhake nga injectors piezo. Ko te tere o enei āhuatanga, ko te nui teitei, na ko ratou ake noa. Heoi, e kore te mea e taea te hanga o Common Rail (seti) ki te whakaputa i o ratou ringa ake e tika ki te matatini o te hoahoa me te kita pai. Na reira, kei te kawea mahi tiaki katoa i runga i te pūnaha i anake i teihana motuhake. Ko te drawback matua o taua waka tenei.

Pehea e mahi i te reira?

te mana mahi te pūnaha mana pūnaha diesel i werohia. ngā te hou actuators, pūoko me ECU. Tango ki pūkete tawhā katoa - tūnga o te whakatere, te pāmahana coolant, te nui o te rangi, me te ara te hanganga o te haurehu whakapau (i te uiuia lambda). Ki te whakaute ki te actuators, ko ratou te runga ake-whakahuatia pupuha rōnaki, wahie papu, regulator me vaolo. Na, me pehea te pūnaha mahi? I runga i nga tohu e whakahaere nga pūoko mohio a, i hanga te pūnaha te nui e hiahiatia ana o wahie. Kei te whangai te reira i roto i te piha kia inea te. Fuel tae te papu, a ka haere te pēhanga ki runga i te ara rōnaki. Te pēhanga e hiahiatia ana i roto i te regulator motuhake mau. I te tahi vahi, e tango te rorohiko he tohu i nga injectors, me te hunga whakamana i roto i te whakatuwheratanga o te takere i te tetahi wā o te wā. Tei runga i te aratau o mahi o te pūkaha, me te pēhanga wahie e taea te huri i aunoa i te pūnaha i runga i te pūtake o ngā raraunga i te pūoko hāora. Heoi, kia iti i te oma. Nui ine tohu hara ki te pūnaha "Common Rail".

Ngā momo o te werohanga Common Rail

He aha te mea te reira? He maha ngā momo o te werohanga wahie i roto i te pūnaha:

• Tuatahi.
• Main.
• Kōwhiringa.

Ko te tuatahi e wahi i mua i te tuatahi i roto i te tikanga ki te whakapiki ake i te pēhanga me te pāmahana i roto i te ruma ngingiha. Heoi kawea autoignition vitiviti tiaki matua, me te whakaiti haruru pūkaha. kia rerekē mua-werohia, i runga i te huru whakahaere pūkaha rānei. Ko te kupu, i te mangere e whakaputaina reira rua. Ki te whakanui ake i te kawenga - kotahi. e kore te mua i werohia-whakatinana i kawenga tonu. Ko te whakaaro o te werohanga matua - whakarato tika te pūkaha. Momoroto, e kore e wehea ia. kaimahi werohanga atu ki te whakaiti i hau whakapau te tāoke. Ko te kupu, mai i te pūoko hāora e tango mōhiohio i runga i te rorohiko, a ka tukua ki tetahi atu wahi o te wahie. matū kino afterburned i roto i te whakakōkī (ngā huaina ano a reira i te tātari korakora diesel).

Generation "Common Rail"

E tano ia tapao e puta te whakatupuranga tuatahi o te pūnaha i te 1999 tau. Te reira i te pēhanga putanga o 145 MPa. muri ka haere mai E rua tau te pūnaha whakatupuranga muri (160 MPa). 3 Common Rail whakawhanakehia i roto i te 2005 tau. I te kau, e rite rawa waka ki te pūnaha o "Common Rail" wha whakatupuranga. Ko te nozzles mahi i te pēhanga o 220 MPa. He aha kia nui aro utua ki te pēhanga? Ko te teitei te score, kua patia te atu wahie ki te puoto. Fakatatau ki ai, mo te tetahi wā o te wā kei te mohio te reira atu piki te mana tōtika pūkaha.

mutunga

Na, ka kitea e matou i roto i te mea i te pūnaha werohia tika, me pehea te whakarite i te reira, a pehea te mahi i te reira. E tano ia tapao e whakamahia te "Common Rail" Kei roto i te nuinga o waka diesel, ngā i roto i Europe. Te pūnaha, i roto i te i te noa'tu o tona whīwhiwhi, he pūmanawa nui.
