Mumichina yekuvaka (yakadai semichina yekuchera, michina yekurodha, mabhurudhoza, makireni, uye magiredha),injector yemafutachinhu chakakosha muhurongwa hwemafuta mumainjini edhiziri neepeturu. Zvinangwa zvayo zvikuru nemabasa ayo anotsanangurwa pazasi.
I. Chinangwa Chikuru cheInjector yeFuel
Basa Guru:
Chinopinza mafuta chinopfapfaidza mafuta nemazvo pasi pekumanikidzwa kwakanyanya mukamuri yekupisa yeinjini (kana kuti intake manifold), chichiaisa muzvikamu zvidiki. Izvi zvinoita kuti mafuta nemhepo zvisanganiswe zvakanaka, zvichikonzera kupisa kwakanaka uye kwakasimba.
II. Mabasa Makuru muMichina yekuvaka
| Basa | Tsananguro |
| 1. Kudzora Kuwanikwa kweMafuta | Injector iyi inonyatso tarisa huwandu hwemafuta anopinzwa, pasi peECU (Electronic Control Unit), kuti ienderane nemutoro weinjini, kumhanya, uye mamiriro ekushanda. |
| 2. Kuvandudza Kushanda Nesimba Kwekupisa | Kupinza maatomu kunobatsira kusanganisa mafuta nemhepo zvakakwana, zvichiita kuti pave nekutsva kwakakwana uye kushanda zvakanaka kwekupisa. |
| 3. Kuderedza Kushandiswa Kwemafuta | Kupinza mafuta nemazvo kunoderedza marara emafuta, zvichibvumira michina yekuvaka kuchengetedza mashandiro emafuta kunyangwe ichishanda kwenguva refu. |
| 4. Kuderedza Hutsi Hunobva Mumhepo | Kupisa kwakagadziriswa kunoderedza kuburitswa kwemahydrocarbon asina kupiswa (HC), kabhoni monoxide (CO), uye zvinhu zvidiki (PM). |
| 5. Kuvandudza Mhinduro yeInjini | Kugadziriswa nekukurumidza kwenguva yekuisa jekiseni uye vhoriyamu kunoita kuti simba risvike zvakanaka uye injini inokurumidza kupindura panguva yekuchinja mutoro. |
III. Nzvimbo dzekuisa uye Kugadziriswa kweSisitimu
Kuiswa Kwakajairika:
Injini dzeDiziri: Dzinoiswa pamusoro pesirinda, dzichipinza mafuta zvakananga mukamuri rinopisa (direct injection system).
Injini dzePeturu (dzisingawanzoitiki mumichina yekuvaka): Dzinoiswa mu intake manifold kana zvakananga mu combustion chamber (multi-point kana direct injection).
Zvikamu Zvakajairika zveSisitimu Yekupinza Mafuta:
Tangi remafuta
Pombi yemafuta
Njanji yemafuta
Chinhu Chinopinza Mafuta
ECU (Chikamu Chekudzora Zvemagetsi)
IV. Mienzaniso yeKushandiswa
Zvicherwa (Injini yeDiesel): Injector imwe chete pa cylinder musystem yemagetsi ine simba guru.
MaLoaders: Kupinza jekiseni nemazvo panguva yekushanda kwemutoro wakawanda kunoita kuti torque ibude zvakanaka.
Mabulldozer: Anochengetedza mafuta akagadzikana kana achimhanya zvishoma uye achikwanisa kufamba nesimba.
