Injector ya Mafuta Apamwamba Apamwamba a Dizilo 370-7287 Common Rail Fuel Injector 3707287 ya Denso ya Caterpillar CAT C4 Engine

Majekeseni abwino kwambiri amafuta amathandiza injini kutulutsa mphamvu zambiri kwinaku akuchepetsa kugwiritsa ntchito mafuta komanso kuchepetsa kuipitsidwa. Majekeseni amafuta okhala ndi ukadaulo waposachedwa amathandizira kuchepetsa kutulutsa mpweya wa kaboni ndi wowonjezera kutentha popereka mafuta olondola ndi kusanganikirana kwa mpweya. Nkhaniyi ikufotokoza za jekeseni wamafuta ndi momwe imagwirira ntchito mu injini za dizilo, gasi, ndi haidrojeni komanso m'magalimoto amafuta a hydrogen.

KODI IJEKIKTA WA MAFUTA AMACHITA CHIYANI?

Injector yamafuta imayang'anira jekeseni wamafuta muchipinda choyatsira mkati mwa injini momwe amasakanikirana ndi mpweya ndikuyatsa. Chipinda choyaka moto ndi pomwe mphamvu zamagetsi mu dizilo, haidrojeni, ndi gasi wachilengedwe zimasinthidwa kukhala mphamvu yagalimoto. Ikayendetsedwa ndi gawo loyang'anira zamagetsi (ECU), jekeseniyo imapereka kuchuluka kwake kwamafuta kuti zitsimikizire kuyaka bwino.

KODI IJEKITA WA DIESEL AMAGWIRA BWANJI?

Injector yamafuta mu injini ya dizilo imakhala ndi solenoid (mtundu wa electromagnet), nozzle, ndi singano mkati mwa jekeseni. Ma injini a dizilo amakono ndi jakisoni wachindunji, kutanthauza kuti mafuta amaperekedwa mwachindunji muchipinda choyaka.

Mu silinda, mpweya umapanikizidwa ndi kukwera kwa pistoni. Pamene pisitoni imayandikira pamwamba pa njira yake, chizindikiro chamagetsi chimatumizidwa ku solenoid, kuchititsa kuti singano ya jekeseni ikwezeke, ndikulola kuti mafuta othamanga kwambiri (mpaka 37,000 psi) ayendetse mumphuno ndi kulowa m'chipinda choyaka kuti asakanize. mpweya. Chifukwa cha kutentha kokwezeka komwe kumabwera chifukwa cha kuponderezana, mafuta osakanikirana a mpweya amayaka moto, kupanga mphamvu ndikuyendetsa ma pistoni a injini.

Kuphatikizika kwa kuthamanga kwamafuta ambiri komanso mabowo abwino kwambiri ojambulira nozzle kumapangitsa kusakanikirana bwino kwa mpweya ndi mafuta kuti zikwaniritse miyezo yokhwima yotulutsa mpweya. Mu injini za dizilo, jekeseni wamafuta amatha kuyatsa ma pulse angapo pamagetsi amodzi omwe angagwiritsidwe ntchito pochepetsa phokoso komanso kuwongolera mpweya.
