Impompo yeoli yelori yophukile kwaye inezi mpawu.
1. Ukukhawuleza okubuthathaka kunye nemvakalelo yokukhathazeka xa ufaka i-refueling.
2. Akukho lula ukuqalisa xa uqala, kwaye kuthatha ixesha elide ukucofa izitshixo.
3. Kukho isandi esingxolayo ngelixa uqhuba.
4. Isibane sempazamo ye-injini sivuliwe.Injini iyashukuma.

Iimbangela zeimpompo yeoliumonakalo:
1. Xa umgangatho we-oyile uphantsi, itanki yamafutha iya kuzaliswa ngokungcola okuhlukeneyo okanye izinto zangaphandle.Nangona impompo ye-oyile inesihluzo sokucoca i-petroli, inokuthintela kuphela amasuntswana amakhulu okungcola.Iincinci ezincinci zokungcola ziya kutsalwa kwi-oil pump motor, eya kubangela umonakalo kwimpompo yeoli ngokuhamba kwexesha.
2. Isihluzo se-petroli asizange sitshintshwe ixesha elide, kwaye inkqubo yokubonelela nge-petroli yokucoca i-petroli ivalwe kakhulu, okubangela ubunzima bokupompa ioli.Iimeko zomthwalo wexesha elide zibangela umonakalo kwipompo yepetroli.
Ngokweendlela ezahlukeneyo zokuqhuba, iimpompo zepetroli zinokwahlulwa zibe yi-diaphragm yomatshini kunye nohlobo lokuqhuba umbane.
1. Ipompo yepetroli yohlobo lwe-diaphragm yindlela emele i-carburetor type engine.Umgaqo wayo wokusebenza uqhutywa yivili le-eccentric kwi-camshaft.Umgaqo wayo wokusebenza kukuba ngexesha lokujikeleza kwe-oyile yokufunxa i-camshaft, xa ingalo ejikelezayo phezulu kwe-eccentric idonsa intonga yepompo ye-diaphragm, i-diaphragm yepompo yehla, ivelisa ukufunxa, kwaye i-petroli ikhutshwe kwitanki yamafutha, kwaye emva koko udlula kumbhobho wepetroli, isihluzo sepetroli, intonga yepompo ye-diaphragm kunye nesixhobo sokumpompa i-oyile senza ukufunxa.
2. Ipompo yepetroli yombane ayiqhutywa yi-camshaft, kodwa ixhomekeke kumandla ombane we-electromagnetic ukumunca ngokuphindaphindiweyo i-membrane yempompo.

Kufuneka kutshintshwe kangaphi impompo:
Akukho mjikelo omiselweyo wokutshintsha iimpompo zepetroli.Ngokuqhelekileyo, emva kokuba isithuthi sihambe malunga neekhilomitha ezili-100,000, impompo yepetroli ingaba yinto engaqhelekanga.Nangona kunjalo, isihluzo sepetroli sinokutshintshwa malunga neekhilomitha ezingama-40,000.Xa uhlola kwaye ugcina ipompo yeoli yemoto, kufuneka uye kwivenkile yokulungisa ingcali ukuze ugweme iingxaki ngexesha lenkqubo yokuqhaqha, enokubangela ukungaphumeleli okukhulu kunye nokulahlekelwa okungafunekiyo.
