Chinopinza mweya muinjini ivharuvhu inodzorwa inodzora kufamba kwemhepo ichipinda muinjini. Kana gasi rapinda mupombi yekupinda, rinosanganiswa nepeturu uye rinova musanganiswa unobvira, uyo unozotsva woshanda. Rinobatanidzwa nefirita yemhepo, iyo inovhara injini, inozivikanwa sehuro yeinjini yemotokari.
Injini dzepeturu dzinoshandiswa pakupinza injini dzine simba remagetsi dzinotaridzika seizvi. Throttle ndeimwe yenzvimbo dzakakosha dzeinjini dzemotokari dzemazuva ano dzinoshandisa magetsi. Chikamu chepamusoro chayo i air filter, chikamu chezasi i engine cylinder block, uye ndiyo huro yeinjini yemotokari. Kumhanyisa mota kunochinjika, uye throttle yakasviba ine hukama hwakanaka, kuchenesa throttle kunogona kuderedza kushandiswa kwemafuta kunogona kuita kuti injini ichinjike uye ive yakasimba. Throttle haifanirwe kubviswa kuti icheneswe, asiwo chinangwa chevaridzi kuti vakurukure zvakawanda.
