Kodi mafuta amafuta amagwira ntchito bwanji m'galimoto yamakono?

Magalimoto asintha kwambiri pazaka khumi zapitazi, ndipo vuto lalikulu lomwe opanga athana ndi izi ndi kuchuluka kwa mafuta omwe injini imagwiritsa ntchito. Chifukwa chake, machitidwe amafuta amagalimoto amakono amatha kukhala ovuta kwambiri. Mwamwayi, njira zovuta kwambiri zopulumutsira mafuta m'magalimoto zimaphatikizapo kukonza ECU. Mwakuthupi, pansi pa hoods za magalimoto amakono mungapeze njira zochepa chabe za dongosolo la mafuta.

imayamba ndi pompa

Tanki yamafuta agalimoto ndi yomwe ili ndi udindo wosunga mafuta ambiri mumafuta. Tanki iyi imatha kudzazidwa kuchokera kunja kudzera pa kabowo kakang'ono komwe kamamata ndi kapu ya gasi pomwe sikugwiritsidwa ntchito. Gasi ndiye amadutsa magawo angapo asanafike pa injini:

• Choyamba, gasi amalowa mpope mafuta. Pampu yamafuta ndi yomwe imatulutsa mafuta kuchokera mu tanki yamafuta. Magalimoto ena amakhala ndi mapampu angapo amafuta (kapena matanki angapo amafuta), koma makinawa amagwirabe ntchito. Ubwino wokhala ndi mapampu angapo ndikuti mafuta sangathe kutsika kuchokera kumapeto kwa thanki kupita kwina potembenuka kapena kuyendetsa potsetsereka ndikusiya mapampu amafuta owuma. Pampu imodzi idzaperekedwa ndi mafuta nthawi iliyonse.

• Pampu imatulutsa mafuta mizere yamafuta. Magalimoto ambiri amakhala ndi mizere yolimba yachitsulo yomwe imawongolera mafuta kuchokera ku tanki kupita ku injini. Amathamangira mbali zina za galimoto momwe sangawonekere kwambiri ndi zinthu ndipo sangatenthe kwambiri chifukwa cha utsi kapena zinthu zina.

• Asanalowe mu injini, gasi ayenera kudutsa fyuluta yamafuta. Fyuluta yamafuta imachotsa zonyansa zilizonse kapena zinyalala mu petulo isanalowe mu injini. Ichi ndi sitepe yofunika kwambiri ndipo fyuluta yoyera yamafuta ndiye chinsinsi cha injini yayitali komanso yoyera.

• Pomalizira pake, gasiyo amafika pa injini. Koma zimalowa bwanji m'chipinda choyaka moto?

Zodabwitsa za jekeseni wamafuta

Kwa zaka zambiri za zaka za m'ma 20, ma carburetor adatenga mafuta a petulo ndikusakaniza ndi mpweya woyenerera kuti uyatse m'chipinda choyaka. Carburetor imadalira mphamvu yokoka yomwe imapangidwa ndi injini yokhayo kuti ikoke mpweya. Mpweya uwu umanyamula mafuta, omwe amapezekanso mu carburetor. Mapangidwe osavutawa amagwira ntchito bwino, koma amavutika pamene zofunikira za injini zimasiyanasiyana pa RPMs. Chifukwa throttle imatsimikizira kuchuluka kwa mpweya / mafuta omwe carburetor amalola kulowa mu injini, mafuta amalowetsedwa m'njira yofananira, yokhala ndi mphamvu yofananira ndi mafuta ambiri. Mwachitsanzo, ngati injini ikufunika 30% mafuta ochulukirapo pa 5,000 rpm kusiyana ndi 4,000 rpm, zidzakhala zovuta kuti carburetor ikhale ikuyenda bwino.

Makina opangira mafuta

Pofuna kuthetsa vutoli, jekeseni wamafuta anapangidwa. M'malo molola injini kuti itenge gasi pa mphamvu yake yokha, jakisoni wamafuta amagetsi amagwiritsa ntchito chowongolera mafuta kuti asunge mpweya wosasunthika womwe umapereka mafuta ku ma jekeseni amafuta, omwe amapopera nkhungu m'zipinda zoyatsira moto. Pali njira imodzi ya jakisoni wamafuta omwe amabaya mafuta m'thupi la throttle osakanikirana ndi mpweya. Kusakaniza kwamafuta a mpweya kumeneku kumapita kuzipinda zonse zoyaka ngati pakufunika. Makina a jakisoni wamafuta (omwe amatchedwanso port fuel injection) ali ndi majekeseni omwe amatumiza mafuta molunjika kuzipinda zoyatsira ndipo amakhala ndi jekeseni imodzi pa silinda imodzi.

Jekeseni wamafuta wamakina

Mofanana ndi mawotchi a pamanja, jakisoni wamafuta akhoza kukhala wamagetsi kapena wamakina. Jakisoni wamafuta amakina pano si wotchuka kwambiri chifukwa umafunika kukonza bwino ndipo amatenga nthawi yayitali kuti muyitanitse pulogalamu inayake. Jekeseni wamafuta amakina amagwira ntchito poyezera mwamakina kuchuluka kwa mpweya womwe ukulowa mu injini ndi kuchuluka kwa mafuta omwe amalowa mu majekeseni. Izi zimapangitsa kusanja kukhala kovuta.

Pakompyuta jekeseni wamafuta

Jakisoni wamafuta amagetsi amatha kukonzedwa kuti azigwira bwino ntchito inayake, monga kuthamanga kapena kukoka, ndipo kusintha kwamagetsi uku kumatenga nthawi yocheperako poyerekeza ndi jakisoni wamafuta wamakina ndipo sikufuna kukonzanso ngati makina a carbureted.

Pamapeto pake, dongosolo mafuta magalimoto amakono akulamulidwa ndi ECU, monga ena ambiri. Komabe, izi sizoyipa, chifukwa mavuto a injini ndi zovuta zina zimatha kuthetsedwa ndikusintha pulogalamu. Kuphatikiza apo, kuwongolera zamagetsi kumalola makina kuti azipeza mosavuta komanso mosasintha kuchokera ku injini. Jakisoni wamafuta amagetsi amathandizira ogula kugwiritsa ntchito bwino mafuta komanso magwiridwe antchito osasinthasintha.
