1. Ukuvikelwa kwemvelo kuyisici esivelele sezithuthuthu zikagesi. Ukushayela kwabo ugesi kuqeda ukukhishwa kwegesi ngesikhathi sokusebenza, okunomthelela omuhle ekuthuthukiseni izinga lomoya kanye nokunciphisa ukungcoliswa kwemvelo. Ukusetshenziswa kabanzi kwezithuthuthu zikagesi emadolobheni kunganciphisa ngempumelelo ukukhishwa kwekhabhoni futhi kube nomthelela endaweni yasemadolobheni ehlaza. Uma kuqhathaniswa nezithuthuthu{4}ezinamandla kaphethiloli, izithuthuthu zikagesi aziwakhiphi amagesi ayingozi njenge-carbon monoxide nama-hydrocarbon, okunomthelela omkhulu ekuvikelweni kwemvelo.
2. Mayelana namandla, izithuthuthu zikagesi zinikeza amandla amakhulu. Bangakwazi ukufinyelela isivinini esithile ngokushesha, bahlangabezane nezidingo zokuhamba ngokushesha. Ukusheshisa kwabo okushelelayo kunikeza umuzwa omnandi wokushayela. Emigwaqweni-enakekelwa kahle, izithuthuthu zikagesi zingadlula kalula futhi zihambe ngokushesha, zonga isikhathi ohambweni lwansuku zonke.
3. Ukusebenza kalula futhi kuyisici esiyinhloko sezithuthuthu zikagesi. Ngaphandle kokushintshwa kwegiya okuyinkimbinkimbi kwezithuthuthu zikaphethiloli{2}ezinamandla, kulula kwabaqalayo ukuzisebenzisa. Ukuqala nokusheshisa kufinyelelwa nge-twist elula ye-throttle, futhi ukubhuleka nokunye ukusebenza nakho kulula futhi kuqondile. Lokhu kusho ukuthi ukushayela isithuthuthu sikagesi kudinga ikhono nesipiliyoni esincane, okwenza kube lula ukusisebenza.
4. Izindleko zokunakekela eziphansi zingenye yezinzuzo zezithuthuthu zikagesi. Ngenxa yesakhiwo sawo esilula nezingxenye ezimbalwa, awadingi ukushintshwa njalo kukawoyela, ama-spark plug, nezinye izakhi ezidingekayo ezithuthuthwini zikaphethiloli{2}ezinamandla. Ukuhlola okuvamile ezingxenyeni ezibalulekile njengebhethri nemoto kanye nokulungisa kalula ngokuvamile kwanele, kunciphisa kakhulu izindleko zokusebenza.
5. Amazinga omsindo aphansi ayinzuzo evelele yezithuthuthu zikagesi. Azikhiqizi umsindo omkhulu ngesikhathi sokusebenza, zivimbela ukuphazamiseka komsindo omkhulu kubahlali abazungezile kanye nemvelo. Lapho esebenza ezindaweni okuhlalwa kuzo noma emigwaqweni yasemadolobheni, mancane amathuba okuthi abangele inkathazo kwabanye ngenxa yomsindo, ngaleyo ndlela ahlangabezane kangcono nezidingo zokuhamba okuzolile emadolobheni.
