Pampu yamafuta yagalimotoyo yasweka ndipo ili ndi zizindikiro izi.
1. Kuthamanga kofooka ndi kukhumudwa pamene mukuwonjezera mafuta.
2. Sikophweka kuyamba poyambira, ndipo zimatenga nthawi yayitali kukanikiza makiyi.
3. Kumamveka phokoso pamene mukuyendetsa galimoto.
4. Kuwala kwa injini kumayaka.Injini ikugwedezeka.

Zoyambitsa zapompa mafutakuwonongeka:
1. Mafuta akakhala osauka, thanki yamafuta idzadzazidwa ndi zonyansa zosiyanasiyana kapena zinthu zakunja.Ngakhale pampu yamafuta ili ndi sefa yosefera mafuta, imatha kutsekereza tinthu tambiri ta zonyansa.Tizidutswa tating'ono ta zonyansa timayamwa mu injini yapampu yamafuta, zomwe zingayambitse kuwonongeka kwa mpope wamafuta pakapita nthawi.
2. Fyuluta yamafuta sinasinthidwe kwa nthawi yayitali, ndipo makina opangira mafuta amafuta amatsekedwa mwamphamvu, zomwe zimapangitsa kuti pakhale zovuta kupopera mafuta.Kulemera kwa nthawi yayitali kumayambitsa kuwonongeka kwa pampu ya petulo.
Malinga ndi njira zosiyanasiyana zoyendetsera, mapampu amafuta amatha kugawidwa m'makina a diaphragm ndi mtundu wamagetsi amagetsi.
1. Pampu yamafuta amtundu wa diaphragm ndi mawonekedwe oyimira injini yamtundu wa carburetor.Mfundo yake yogwirira ntchito imayendetsedwa ndi gudumu la eccentric pa camshaft.Mfundo yake yogwirira ntchito ndi yakuti panthawi yozungulira camshaft yoyamwa mafuta, pamene mkono wogwedezeka pamwamba pa eccentric umakokera pansi ndodo ya pampu, diaphragm imatsika, imatulutsa kuyamwa, ndipo mafuta amatulutsidwa mu thanki yamafuta, ndiyeno amadutsa paipi yamafuta, fyuluta yamafuta, ndodo ya mpope diaphragm ndi chipangizo chopopera mafuta chimatulutsa kuyamwa.
2. Pampu yamagetsi yamagetsi simayendetsedwa ndi camshaft, koma imadalira mphamvu yamagetsi kuti imayamwa mobwerezabwereza pampu.

Kodi pampu iyenera kusinthidwa kangati:
Palibe njira yokhazikika yosinthira mapampu amafuta.Nthawi zambiri, galimoto ikayenda mtunda wa makilomita pafupifupi 100,000, pampu ya petulo imatha kukhala yachilendo.Komabe, fyuluta mafuta akhoza m'malo pafupifupi 40,000 makilomita.Mukayang'ana ndikusunga pampu yamafuta agalimoto, muyenera kupita ku malo ogulitsa akatswiri kuti mupewe zovuta panthawi ya disassembly, zomwe zingayambitse kulephera kwakukulu komanso kutayika kosafunikira.
