Mu makina omanga (monga ma excavator, ma loaders, ma bulldozer, ma cranes, ndi ma grader),chojambulira mafutandi gawo lofunika kwambiri la mafuta mu injini za dizilo ndi petulo. Zolinga zake zazikulu ndi ntchito zake zafotokozedwa pansipa.
I. Cholinga Choyambira cha Injector ya Mafuta
Ntchito Yaikulu:
Chojambulira mafuta chimathira mafuta molondola pansi pa mphamvu yayikulu mu chipinda choyaka moto cha injini (kapena intake manifold), ndikuchiyika mu tinthu tating'onoting'ono. Izi zimatsimikizira kusakanikirana bwino kwa mafuta ndi mpweya, zomwe zimapangitsa kuti kuyaka kukhale kogwira mtima komanso kokhazikika.
II. Ntchito Zazikulu mu Makina Omanga
| Ntchito | Kufotokozera |
| 1. Kulamulira Kupereka Mafuta | Injector imawongolera bwino kuchuluka kwa mafuta omwe amalowetsedwa, motsogozedwa ndi ECU (Electronic Control Unit), kuti igwirizane ndi kulemera kwa injini, liwiro, ndi momwe imagwirira ntchito. |
| 2. Kupititsa patsogolo Kugwiritsa Ntchito Bwino kwa Kuyaka | Kulowetsa kwa atomu kumathandizira kusakaniza bwino mafuta ndi mpweya, zomwe zimapangitsa kuti kuyaka kwathunthu kuyake bwino komanso kuti kutentha kugwire bwino ntchito. |
| 3. Kuchepetsa Kugwiritsa Ntchito Mafuta | Kulowetsa mafuta molondola kumachepetsa kuwononga mafuta, zomwe zimathandiza makina omanga kuti azisunga mafuta bwino ngakhale atagwiritsidwa ntchito nthawi yayitali. |
| 4. Kuchepetsa Utsi Woipa | Kuyaka bwino kumachepetsa kutulutsa kwa ma hydrocarbon osayaka (HC), carbon monoxide (CO), ndi tinthu tating'onoting'ono (PM). |
| 5. Kukonza Kuyankha kwa Injini | Kusintha mwachangu nthawi yojambulira ndi voliyumu kumatsimikizira kuti mphamvu imayenda bwino komanso kuti injini iyankhidwe mwachangu panthawi yosintha katundu. |
III. Malo Okhazikitsira ndi Kasinthidwe ka Dongosolo
Kukhazikitsa Kwachizolowezi:
Mainjini a Dizilo: Amayikidwa pamutu wa silinda, ndikulowetsa mafuta mwachindunji mu chipinda choyaka moto (njira yolumikizira mwachindunji).
Injini za Petroli (zosazolowereka kwambiri m'makina omanga): Zoyikidwa mu intake manifold kapena mwachindunji mu chipinda choyaka moto (multi-point kapena direct injection).
Zigawo Zachizolowezi za Dongosolo Lopangira Mafuta:
Thanki ya Mafuta
Pampu ya Mafuta
Sitima ya Mafuta
Chojambulira Mafuta
ECU (Gawo Lowongolera Zamagetsi)
IV. Zitsanzo za Kugwiritsa Ntchito
Zofukula (Injini ya Dizilo): Injector imodzi pa silinda imodzi mu dongosolo la njanji yamagetsi yamphamvu.
Zojambulira: Kujambulira kolondola kwambiri panthawi yogwira ntchito yolemera kwambiri kumatsimikizira kutulutsa kwamphamvu kwa torque.
Ma Bulldozer: Amasunga mafuta okhazikika pansi pa liwiro lochepa komanso lamphamvu kwambiri.
