Papu-pupuha: whakarōpū me te hanga

Katoa tau Kei te anake tipu te tono mo te engine diesel rite ki paearu pērā i te mana, rauropi ōhanga me te. Na anake te hanganga tino o te ranunga pūkākā taea makona enei whakaritenga. Na reira, i te pūnaha wahie i werohia katoa ko ki te mahi pai, whakarato meneti maputia i raro i te pēhanga teitei.

he pūnaha taua, e fakatahai i kotahi injector wae wahie, me te papu, te papu-atomizer. Waihoki, ko te papu pēhanga teitei, injects te papu-injector te nui etahi o ranunga i te kau tika. Nā ki te meka e mo ia o nga ipurau o te pūkaha i reira he kotahi wae injector, i roto i te pūnaha taua i reira he kore papu wahie i werohia.

nozzles taputapu ngā te matenga rango pai wae diesel injector. Hei kawe ia ratou ki te kaha i runga i te huri kawau 4 he haere motuhake. Ko te kaha i runga i te injectors plungers kōwae tuku te roto i te rocker. Nā ki te kōtaha motuhake te wae injector rocker cam taraiwa o te tuatahi koi ara ake, a ka taka ata.

I te kau, ka reira te mea he ara koi o te ringa rocker, aki te plunger te ki iho tere nui. Na reira, i reira he pēhanga toto tiketike. A, no te tīmata te ringa rocker ki āta hinga, rite te plunger tīmata ki te pōturi me te kaupapa kākahu whakarunga. he hanga taua taea te wahie ki te tomo i te ruma pēhanga tiketike pai, ki kore hanganga o mirumiru rangi. Ko te wā te wā, me te mana i werohia mana takirere solenoid wae injector. Hoki tenei whakaaro, i roto i te hiko wae mana tukua ki te ngaohiko. Ahakoa ine iti i roto i te tipu tawhā puta i rehu kohi wahie, ka tīmata te engine ki "haruru."

Ka taea e diesel injector papu kia o ngā momo e toru: piezoelectric, hiko, electrohydraulic. Ki te piha solenoid whakaturia pupuha rite penehīni me te diesel engines, a ka kua te whakaritenga ohie: te pupuha me te piha solenoid ki te ngira te rehu. Kei te anake tāuta te hiko-injector i runga i engines diesel, e he pea atu ki te mahi i runga i te pūnaha Caumont Ryle. whakaaro Piezoelectric nga engines diesel tino matatau. rongo te injector taua wae te ki 4 nga wa tere atu i te solenoid, me pota patia wahie ki te tika mōrahi.

kia mahi Repair o injectors ka reira ko nga tohu e whai ake nei: nui haere wahie kohi tino, kore ina pato koe i runga i te hau teka, leakage wahie tarapeke i roto i te pūnaha whakapau ranei. Takitahi tere waka iu: ko tonu te ngira tachometer "peke" kahore he take. Taki nga nozzles me whakamana ratou te hanga i runga i tu motuhake, na he reira uaua ki te hanga takitahi ratou: te whakatakoto i te pēhanga o te% 10 anake i runga i te iti, ko te take o rahunga i roto i te pūkaha. A ara, ki te te mahi o te pūnaha wahie e kore e hoatu take mo te āwangawanga, te tātaritanga injector - he tukanga tūtohutia e te i muri i nga 60 000-70 000 km o waka oma.
