Imitha ye-air mass
Isignali yayo isetshenziselwa ukunquma umthamo wenjini, okuthi, kanye nesivinini se-crankshaft, okuyipharamitha eyinhloko yokubala umthamo wamafutha wesisekelo.
Amasistimu wamaphuzu amaningi alawulwa nge-elekthronikhi aqale asebenzisa umjovo ongaqondile kaphethiloli. 
amamitha okugeleza komoya okumanzi okulinganisa ukugeleza kwevolumu okuthathwe injini. Kamuva zathathelwa indawo ngamamitha ocingo olushisayo. Umsebenzi wabo usekelwe eqinisweni lokuthi umoya odonswa injini ugeleza uzungeze into eshisisa ngogesi. Le ndima yadlalwa okokuqala ngocingo lweplatinamu. Uhlelo lokulawula lunikeza ucingo ngogesi ukuze izinga lokushisa layo lihlale liphakeme kunezinga lokushisa lomoya wokungenisa ngenani elingaguquki. Ukugcina umehluko wokushisa oqhubekayo ngokunyuka kwenani lomoya wokungenisa, opholisa ucingo ngamandla, kudinga ukwanda kwenani lamanje eligeleza ngocingo, futhi ngokuphambene nalokho. Inani lamanje lokushisisa liyisisekelo sokubala umthwalo wemoto. Ububi balesi sixazululo kwaba ukuzwela okuphezulu kakhulu ukushaqeka kanye nokulimala komshini. Namuhla, i-laminated heat element isetshenziswa ku-flowmeters yocingo olushisayo. Iyakwazi ukumelana nokushaqeka futhi imelana ne-electromagnetic field.
Njengoba isignali evela kumitha ye-air mass ibaluleke kakhulu ekusebenzeni kahle kwenjini, ukulawula kwayo kucabangela ukuzihlola kwezinhlelo zomjovo. Isibonelo, i-Motronic ihlale iqhathanisa isikhathi somjovo esisuselwe esilinganisweni somoya owuthathayo nalelo elibalwe ngokusekelwe kusivinini senjini kanye ne-engeli ye-throttle. Uma lezi zikhathi zihluke ngokucacile, khona-ke kugcinwa kumemori yokuxilonga yesilawuli, futhi ukushayela okuqhubekayo kusebenzela ukuhlola ukuthi iyiphi inzwa eyonakele. Ngemva kokuba isilawuli sibona inzwa enephutha, ikhodi yephutha ehambisanayo ivela kumemori yesilawuli.
Ukulimala kwenzwa enkulu yokugeleza komoya kungazibonakalisa, okuhlanganisa ukuncipha kwamandla enjini, ukusebenza okungalingani kanye nokusetshenziswa kukaphethiloli ngokweqile.
