Mfundo ya mzere wa mafuta
Chopondera cha waya chokoka chachikhalidwe chimalumikizidwa ku throttle pedal kudzera kumapeto kwa waya wachitsulo ndi throttle valve kumapeto ena. Chiŵerengero chake cha ma transmission ndi 1: 1, kutanthauza kuti, kuchuluka kwa momwe timaponda throttle open Angle ndi kuchuluka kwanji, koma nthawi zambiri, valavu siyenera kutsegula Angle yayikulu chonchi, kotero nyengo ino valavu open Angle si yasayansi kwenikweni, ngakhale njira iyi ndi yolunjika kwambiri koma kulondola kwake kowongolera ndi kotsika kwambiri. Ndipo throttle yamagetsi ndi kudzera mu chingwe kapena waya kuti ilamulire kutsegula throttle, kuchokera pamwamba ndikusintha chingwe cha throttle chachikhalidwe ndi chingwe, koma kwenikweni sikusintha kokha kulumikizana, komanso kumatha kukwaniritsa ntchito yowongolera yokha ya mphamvu yonse yagalimoto.
Ngati dalaivala akufunika kufulumizitsa accelerator, sensa ya malo a pedal izindikira chizindikiro kudzera mu chingwe kupita ku ECU, ECU ikatha kusanthula, kuweruza, ndikupereka lamulo ku drive motor, ndipo drive motor imayang'anira kutsegula kwa throttle, kuti isinthe kayendedwe ka osakaniza oyaka, pakalemera kwambiri, kutsegula kwa throttle kumakhala kwakukulu, kulowa mu silinda ya osakaniza oyaka kwambiri. Ngati kugwiritsa ntchito throttle ya waya wokoka kungadalire phazi kuti liponde pansi pa throttle pedal kuya kuti liwongolere kutsegula kwa throttle, n'zovuta kusintha ngodya yotsegulira throttle kuti ifike pamlingo wa theoretical air-fuel ratio, ndipo electro throttle ikhoza kudzera mu deta ya sensa ya ECU yosonkhanitsidwa kuti isanthule, kuyerekeza, ndikupereka malangizo ku throttle actuator action, throttle ifike pamalo abwino kwambiri, kuti ikwaniritse katundu wosiyanasiyana ndi mikhalidwe yogwirira ntchito ikhoza kukhala pafupi ndi theoretical air fuel ratio ya 14.7: 1 state, kuti mafuta athe kuyatsidwa kwathunthu.
Dongosolo lowongolera throttle lamagetsi limapangidwa makamaka ndi throttle pedal, pedal displacement sensor, ECU (electronic control unit), data bus, servo motor ndi throttle actuator. Displacement sensor imayikidwa mkati mwa accelerator pedal kuti iwunikire malo a accelerator pedal nthawi iliyonse. Kusintha kwa kutalika kwa accelerator pedal kukapezeka, chidziwitsocho chidzatumizidwa ku ECU nthawi yomweyo. ECU idzawerengera chidziwitso ndi zambiri za data kuchokera ku machitidwe ena, ndikuwerengera chizindikiro chowongolera, chomwe chidzatumizidwa ku servo motor relay kudzera mu mzere. Servo motor imayendetsa throttle actuator, ndipo data bus ndiyo imayang'anira kulumikizana pakati pa system ECU ndi ECU ina. Popeza throttle imasinthidwa kudzera mu ECU, electronic throttle systems zitha kukonzedwa ndi zinthu zosiyanasiyana kuti ziwongolere chitetezo choyendetsa ndi chitonthozo, zomwe zodziwika kwambiri ndi ASR (traction control) ndi speed control (cruise control).
