Majekiseni emafuta anoita basa rakakosha mumainjini edhiziri. Iyo inonyanya kukonzeresa jekiseni mafuta mukamuri yekupisa injini nekumanikidza chaiko, nguva uye atomization. Kuburikidza nekutonga kwakaringana jekiseni remafuta, inova nechokwadi chekuti mafuta anogona kusanganiswa zvizere nemhepo, nekudaro achiwana kupisa kwakanaka.

Injector yemafuta inogona kunyatsogadzirisa huwandu uye nguva yejojo ​​yemafuta maererano nemamiriro akasiyana-siyana ekushanda kwejini, zvakadai sekukurumidza, mutoro, etc. Isai mafuta nokukurumidza pakutanga kuti uone kupisa kwakanaka; kuwedzera huwandu hwejekiseni yemafuta pamitoro yakakura kuti ipe simba rakakwana; kuderedza kuwanda kwejekiseni remafuta pamitoro yakaderera kuchengetedza mafuta. Kuita kwakanaka kwejekiseni remafuta kunobatsira kuvandudza simba reinjini, hupfumi uye kuita kwekuburitsa. Inogona kuita kuti kupisa kuve kwakakwana, kuderedza kusvibiswa kwemhepo kunokonzerwa nekupisa kusina kukwana, uye zvakare kubvumira injini kuti ibudise simba rine simba rakawanda. Uye zvakare, kunyatso kudzora kwemafuta majekiseni kunogona zvakare kuderedza kushandiswa kwemafuta uye kunatsiridza kushandiswa kwemafuta. Mhando dzakasiyana uye zvirevo zvemajekiseni zvinochinjika kune akasiyana enjini madhizaini uye zvinodiwa zvekushandisa, uye pamwe chete inovimbisa kushanda kwakagadzikana uye kwakavimbika kweinjini.

Kukundikana kwakajairika jekiseni remafuta kunosanganisira zvinotevera:
Yakashata atomization: Nekuda kweizvozvo, mafuta haagone kuve atomu zvakanaka, zvichikanganisa kupisa kwemoto, izvo zvinogona kukonzera simba reinjini kudzikira, kushandiswa kwemafuta kuwedzera, uye kuburitsa kuderera.
Kudonha: Mafuta anoramba achidonha kubva mujekiseni, izvo zvinoita kuti musanganiswa uwedzere kupfuma, zvichiita kuti injini ishande isina kugadzikana, kuzununguka, uye kunyange kutanga zvakaoma.
Kuvhara: Kusachena uye zvimwe zvinhu zvinogona kuvhara maburi ejekiseni kana nzira dzemukati dzejekiseni, zvichikonzera kudzikiswa kwejekiseni remafuta kana kusavapo jekiseni remafuta, zvichikonzera matambudziko senge simba reinjini isina kukwana uye kushomeka kwecylinder.
Abnormal jekiseni remafuta: Kunyanya kukwira kana kuderera zvakanyanya kunokanganisa jekiseni remafuta, zvichitungamira mukusakwana kupisa kana kuita kushomeka kwesimba.
Solenoid coil kutadza: senge coil short circuit, open circuit, etc., zvinozoita kuti jekiseni ritadze kushanda nemazvo.
Stuck valve tsono: Inogona kudzivirira jekiseni remafuta kubva pakuvhura kana kuvhara zvakajairika, zvichikanganisa kufambira mberi kwakajairika kwejekiseni remafuta.
