Izijovo zikaphethiloli zidlala indima ebalulekile ezinjinini zikadizili. Ikakhulukazi inesibopho sokujova uphethiloli endaweni evuthayo yenjini ngomfutho oqondile, isikhathi kanye ne-atomization. Ngokulawulwa okunengqondo komjovo kaphethiloli, kuqinisekiswa ukuthi uphethiloli ungaxutshwa ngokugcwele nomoya, ngaleyo ndlela kuzuze ukuvutha okuphumelelayo.

Umjovo kaphethiloli ungalungisa ngokunembile inani kanye nesikhathi sokujova uphethiloli ngokuya ngezimo ezihlukene zokusebenza zenjini, njengejubane, umthwalo, njll. Jova uphethiloli ngokushesha ekuqaleni ukuze uqinisekise ukuthungela okushelelayo; ukwandisa inani lomjovo wamafutha emithwalweni ephezulu ukuze unikeze amandla anele; yehlisa inani lomjovo kaphethiloli emithwalweni ephansi ukuze wonge uphethiloli. Ukusebenza kahle komjovo kaphethiloli kusiza ukuthuthukisa amandla enjini, ukonga nokusebenza kwentuthu. Ingenza ukusha kuphelele, kunciphise ukungcola okubangelwa ukuvutha okungaphelele, futhi ivumele injini ukuthi ikhiphe amandla anamandla kakhulu. Ukwengeza, ukulawula okunembayo kwama-injection kaphethiloli nakho kunganciphisa ukusetshenziswa kukaphethiloli futhi kuthuthukise ukusetshenziswa kukaphethiloli. Izinhlobo ezahlukene kanye nokucaciswa kwama-injection kuzivumelanisa nemiklamo ehlukahlukene yenjini kanye nezidingo zohlelo lokusebenza, futhi ndawonye kuqinisekisa ukusebenza okuzinzile nokuthembekile kwenjini.

Ukwehluleka okujwayelekile komjovo kaphethiloli kufaka phakathi lokhu okulandelayo:
Ukungasebenzi kahle kwe-athomu: Ngenxa yalokho, uphethiloli awukwazi ukwenziwa i-athomu kahle, okuthinta ukusebenza kahle kwamandla omlilo, okungase kubangele ukuncipha kwamandla enjini, ukusetshenziswa kukaphethiloli kukhuphuke, kanye nesisi esikhiphayo siwohloke.
Ukuconsa: Isibaseli silokhu siconsa sisuka kumjovo, okuzokwenza ukuthi ingxube inothe kakhulu, okubangele ukuthi injini ingasebenzi kahle, inyakaze, futhi iqale kanzima.
Ukuvala: Ukungcola nezinye izinto kungase kuvale izimbobo zomjovo noma amashaneli angaphakathi omjovo, okubangele ukunciphisa umjovo kaphethiloli noma ngisho nokungajoviswa kukaphethiloli, kubangele izinkinga ezifana namandla enjini anganele kanye nokushoda kwesilinda.
Ingcindezi yomjovo kaphethiloli engavamile: Ukucindezela okuphezulu kakhulu noma okuphansi kakhulu kuzothinta umphumela womjovo kaphethiloli, okuholela ekushiseni okunganele noma ukusebenza kabi kwamandla.
Ukuhluleka kwekhoyili ye-Solenoid: okufana ne-coil short circuit, i-open circuit, njll., kuzobangela ukuba i-injector yehluleke ukusebenza kahle.
Inalithi ye-valve enamathela: Ingase ivimbele umjovo kaphethiloli ekuvulekeni noma ekuvaleni ngendlela evamile, ngaleyo ndlela kuthinte ukuqhubeka okuvamile komjovo kaphethiloli.
