Iyo throttle inzvimbo inodzorwa yevharanda inodzora kuyerera kwemhepo kuinjini. Gasi painopinda pombi yekudya, ichasanganiswa nepeturu uye ive musanganiswa unopisa, iyo ichapisa uye kuita basa. Iyo yakabatana nemhepo firita, iyo injini block, inozivikanwa sehuro yekota injini.
Throttle ina ina stroke peturu injini dzinowanzoita senge izvi. Throttle ndiyo imwe yezvinhu zvakakosha zveyunguva yanhasi jekiseni jekiseni enhokiti system. Chikamu chepamusoro cheiyo iyo yemhepo firita, chikamu chepazasi ndiyo injini cylinder block, uye iri huro yeinjini yemotokari. Kuwedzera kwemotokari kunochinja, uye iyo yakasviba iyo svutugadzike ine hukama hukuru, kucheneswa kwekuchenesa kunogona kuderedza kushandiswa kwemafuta kunogona kuita kuti injini inoshanduka uye yakasimba. Iyo stickttle haifanirwe kubviswa kuchenesa, asi zvakare inotarisisa yevaridzi vevaridzi kukurukura zvakawanda
