Kodi kupaka mafuta kumagwira ntchito bwanji?

Pankhani ya magwiridwe antchito a injini, pali zinthu zochepa zofunika kwambiri kuposa kutumiza mafuta. Mpweya wonse womwe mungathe kuukakamiza kulowa m'masilinda sungachite chilichonse popanda mafuta okwanira kuti awotchedwe. Pamene injini zinakula m'zaka zonse za m'ma XNUMX, panafika nthawi pamene ma carburetors anakhala ofooka kwambiri pofalitsa potengera mphamvu komanso kudalirika. Jekeseni wamafuta kuyambira pamenepo wakhala chinthu chokhazikika mugalimoto iliyonse yatsopano.

Mafuta ojambulira atomize gasi, kupereka mowonjezereka komanso mosasinthasintha m'chipinda choyaka. Mosiyana ndi ma carburetors, omwe amadalira vacuum yomwe imapangidwa ndi injini kuti ipereke mafuta kumasilinda, makina ojambulira mafuta amatulutsa molondola kuchuluka kwamafuta nthawi zonse. Magalimoto amakono amagwiritsa ntchito makina ojambulira mafuta amagetsi omwe amayendetsedwa ndi ECU.

Kukula kwa jekeseni wamafuta kunali kodziwikiratu monga kukwera kwa kutchuka kwa magalimoto omwewo. Kumayambiriro kwa zaka za m'ma 20, zinali zosaneneka kuti galimoto ifike 60 mph. Kumayambiriro kwa zaka za m’ma 21, anthu anali kubuula chifukwa cha kuchulukana kwa magalimoto m’misewu ikuluikulu pamtunda wa makilomita 60 pa ola limodzi. Masiku ano magalimoto ndi odalirika kwambiri ndipo amakonzedwa kuti azitha kuyenda bwino komanso kuti azikhala otetezeka kuposa mmene aliyense akanaganizira zaka XNUMX zapitazo.

Kodi jekeseni wamafuta ndi chiyani?

Makina a jakisoni wamafuta adaperekedwa ngati kukweza kwa ma carburetor pomwe adawonekera koyamba ndikukhalabe m'gawolo mpaka m'ma 1980 pomwe adakhala zida zokhazikika pagalimoto iliyonse yatsopano. Jekeseni wamafuta umapereka maubwino angapo kuposa carburetor, koma pamapeto pake mtengo wopangirawo unapha carburetor.

Kwa nthawi yayitali, ma carburetor akhala njira yosavuta komanso yotsika mtengo kwambiri kwa opanga magalimoto kuti azipereka mafuta kumasilinda a injini zawo. Kuchepa kwa mafuta m'zaka za m'ma 1970 kunakakamiza boma kuti likhazikitse kayendetsedwe ka mafuta agalimoto. Pamene opanga amafunikira kupanga mapangidwe abwino kwambiri a carburetor ndikupanga zida zovuta kwambiri, mtengo wopangira magalimoto opangidwa ndi carburetor udakwera kwambiri kotero kuti jakisoni wamafuta adakhala njira yotsika mtengo.

Kwa ogula, iyi inali nkhani yabwino. Magalimoto okhala ndi jekeseni wamafuta amayendetsa mosasinthasintha ndipo amafuna kusamalidwa komanso kusinthidwa pang'ono. Kutulutsa kwamafuta kumakhala kosavuta kuwongolera ndipo kuchuluka kwamafuta kumachulukira chifukwa chopereka mafuta moyenera. Pali njira zambiri zoyatsira mafuta, koma zonse zitha kugawidwa m'magulu awiri: jakisoni wamafuta wamakina ndi jakisoni wamafuta amagetsi.

Jekeseni wamafuta wamagetsi (EFI)

Jekeseni wamafuta amagetsi amalola kuwongolera molondola kuchuluka kwamafuta omwe amabadwira mu masilinda. Zimatsatira njira yosavuta:

1. Mafuta amatuluka mu thanki yamafuta mpope mafuta. Imadutsa mumizere yamafuta kupita ku injini.

2. Kagawo makina kuwongolera kuthamanga kwamafuta amachepetsa kuyenda kwa mafuta ndipo amangodutsa ndalama zowerengeka kwa ma injectors.

3. Wowongolera kuthamanga kwamafuta amadziwa kuchuluka kwamafuta oti apereke kwa ma injectors, malinga ndi chizindikiro chochokera mass air flow sensor (MAF). Sensa iyi imayang'anira kuchuluka kwa mpweya womwe ukulowa mu injini nthawi iliyonse. Kuchuluka kwa mpweya wolowa mu injini, pamodzi ndi chiŵerengero choyenera cha mpweya / mafuta chokhazikitsidwa ndi wopanga, chimapereka zamagetsi zamagetsi (ECU) zambiri zokwanira kuwerengera kuchuluka kwamafuta omwe injini imafunikira.

4. Majekeseni amafuta amatseguka kuti alole mpweya wa atomu kulowa muchipinda choyaka kapena kulowa m'thupi.

Jekeseni wamafuta wamakina

Jekeseni wamafuta wamakina adapangidwa EFI isanachitike ndipo idatsegula njira yopangira ukadaulo wa EFI. Kusiyana kwakukulu pakati pa machitidwe awiriwa ndikuti makina ojambulira mafuta amakina amagwiritsa ntchito zida zamakina kuti apereke kuchuluka kwamafuta oyenera mu injini. Makinawa amayenera kukonzedwa kuti agwire bwino ntchito, monga ma carburetors, komanso kupereka mafuta kudzera majekeseni.

Kuwonjezera pa kukhala olondola kwambiri, machitidwewa sanali osiyana kwambiri ndi anzawo a carbureted. Komabe, zinali zothandiza kwambiri kwa injini za ndege. Ma carburettor sagwira ntchito bwino motsutsana ndi mphamvu yokoka. Pofuna kuthana ndi mphamvu za g zopangidwa ndi ndege, jakisoni wamafuta adapangidwa. Popanda jakisoni wamafuta, kusowa kwamafuta kungapangitse injini zandege zambiri kuzimitsa panthawi zovuta.

Jekeseni wamafuta amtsogolo

M'tsogolomu, jekeseni wamafuta adzakhala wolondola kwambiri komanso wodalirika komanso wotetezeka kwambiri. Chaka chilichonse injini zimakhala ndi mphamvu zambiri za akavalo ndipo zimatulutsa zinyalala zochepa pa mphamvu ya akavalo.
