Pampu ya petulo
Ntchito ya pampu yamafuta ndikuyamwa mafuta a pekani mafuta a mafuta ndikuwakakamiza chipinda chomenyedwa cha wotchinga papaipi ndi fyuluta yamafuta. Ndi chifukwa cha pampu yamafuta omwe thanki ya mafuta a petulo imatha kuyikidwa kumbuyo kwagalimoto kutali ndi injini ndi pansipa injini.
Mapampu a petulo amatha kugawidwa mu mtundu wamakina a diaphragm ndi mtundu wamagetsi malinga ndi njira zosiyana zoyendetsa.

Kupatula
Mapampu a petulo amatha kugawidwa mu mtundu wamakina a diaphragm ndi mtundu wamagetsi malinga ndi njira zosiyana zoyendetsa.
Pampu ya Diaphragm
Pampogm mafuta pampu ndi nthumwi ya pampu yamagetsi. Imagwiritsidwa ntchito mu injini ya carburetor ndipo nthawi zambiri imayendetsedwa ndi gudumu la eccentric pa camshaft. Makhalidwe ake ndi awa:
① Nthawi yosinthira yamafuta yoyatsira mafuta, pomwe gudumu la engcentric imakankhira mkono wa diaphrargm ndikutulutsa mafuta osokoneza bongo ndikutulutsa chitoliro cha mafuta kudzera mu chitoliro cha mafuta, malo osefera mafuta.
Mafuta owombera pomwe mawilo a eccentric azungulira ngodya inayake ndipo sakankhira mkono wa rockene, ndikuwakakamiza mafuta ku chipinda chopondaponda.
Mapapu a diaphragm phula amadziwika ndi kapangidwe kambiri, koma chifukwa amakhudzidwa ndi kutentha kwa injini, chidwi chake chiyenera kulipidwa kuwonetsetsa kuti mukupopera magwiridwe otentha kwambiri komanso kukhazikika kwa mafuta a mphira ndi mafuta.
Nthawi zambiri, mafuta opangira mafuta pampu mafuta ndi 2,5 mpaka 3.5 mpaka 3.5 mpaka nthawi yayikulu kuposa kugwiritsa ntchito mafuta ambiri. Pamene phula lamafuta wamafuta ndilokulirapo kuposa kugwiritsa ntchito mafuta ndi valavu ya singano yomwe imayandama ya carburetor imatsekedwa, yomwe imaponderezedwa pampu yopanga mafuta, imafupikitsa stroke kapena kuyimitsa ntchitoyo.
Pampu yamagetsi yamagetsi
Pampu yamagetsi yamagetsi imadalira Camshaft kuyendetsa, koma imadalira mphamvu yamagetsi kuti iduleni mutu. Pup yamagetsi yamtunduwu imatha kusankha mwaufulu kukhazikitsa, ndipo imatha kupewa chotsekera mpweya.
Mitundu yayikulu ya mapampu yamagetsi yamagetsi yamagetsi yamagetsi yamagetsi imayikidwa mu bomba la mafuta kapena thanki ya mafuta. Zoyambazo zili ndi kuchuluka kwakukulu, sikufunikira thanki yopangidwa mwapadera, ndipo ndikosavuta kuyiyika ndikusinthana. Komabe, gawo loikika lamafuta lotentha la pampu yamafuta litakhala lalitali, ndizosavuta kupanga mpweya, ndipo phokoso logwira ntchito lilinso lalikulu. Kuphatikiza apo, pamafunika kuti pampu yamafuta sayenera kutayikira. Mtunduwu sugwiritsidwa ntchito pamagalimoto atsopano. Wotsirizayo ali ndi mapaipi a mafuta osavuta, phokoso lotsika, komanso zofunikira zotsika mtengo zingapo, zomwe zimachitika kwambiri.
Mukamagwira ntchito, kuchuluka kwa pampu ya mafuta sikungangopereka chithandizo chomwe chimagwiritsidwa ntchito pochita injiniya, komanso kuonetsetsa kuti mafuta abwezeretse mafuta kuti awonetsetse kukakamiza kwa kukakamiza kwa mafuta.
