Gavhuna wemagetsichishandiso chekudzora kumhanya kwejenareta, chinoshandiswa zvakanyanya mukurongedza, kudhinda, zvemagetsi, chiridzwa, michina yekurapa uye mamwe maindasitiri mutsara wekugadzira senge yekumhanyisa kudzora mudziyo, zvinoenderana nechiratidzo chemagetsi chinogamuchirwa, kuburikidza nemutongi uye actuator kushandura saizi yepombi jekiseni remafuta, kuitira kuti injini yedhiziri igone kumhanya nekumhanya kwakagadzikana. Izvi zvinotevera zvinokutungamirira kuti udzidze chimiro uye nheyo yekushanda yegavhuna wemagetsi.
Gavhuna wemagetsi muchimiro uye nheyo yekutonga yakasiyana zvakanyanya kubva kune mechanical gavhuna, ndiko kumhanya uye (kana) kuchinja kwemutoro muchimiro chemagetsi masaini anotumirwa kune control unit, uye set voltage (ikozvino) chiratidzo chinofananidzwa ne kubuda kwechiratidzo chemagetsi kune actuator, actuator chiito chinodhonza rack yemafuta kuti iwedzere kana kuderedza mafuta, Kuzadzisa chinangwa chekukurumidza kugadzirisa injini. Gavhuna wemagetsi anotsiva iyo inotenderera inobhururuka uye zvimwe zvivako mumagetsi gavhuna nemagetsi ekugadzirisa zviratidzo, pasina kushandiswa kwemagetsi emagetsi, chiito chacho chinonzwisisika, kukurumidza kupindura kunokurumidza, uye maitiro ane simba uye akadzikama akakwirira; Electronic gavhuna hapana gavhuna dhiraivha michina, diki saizi, nyore kuisa, nyore kuwana otomatiki kudzora.
Kune maviri akajairika magavhuna emagetsi: single pulse electronic governor uye double pulse electronic governor. Iyo monopulse yemagetsi gavhuna anoshandisa iyo yekumhanyisa pulse chiratidzo kugadzirisa mafuta ekupa. Kaviri pulse yemagetsi gavhuna ndiko kumhanya uye mutoro weiyo maviri monopulse siginecha yakasimudzwa kugadzirisa mafuta ekupa. Iyo kaviri pulse yemagetsi gavhuna inogona kugadzirisa mafuta emafuta asati achinja mutoro uye kukurumidza kusati kwachinja, uye kugadzirisa kwayo kururamisa kwakakwirira kudarika iyo imwechete pulse electronic gavhuna, uye inogona kuvimbisa kugadzikana kwemagetsi emagetsi.
1- Actuator 2- Diesel injini 3- speed sensor 4- dhiziri mutoro 5- load sensor 6- Speed control unit 7- speed setting potentiometer
Iyo yakakosha kuumbwa kwekaviri pulse electronic governor inoratidzwa mumufananidzo. Iyo inonyanya kuumbwa ne actuator, yekumhanyisa sensor, mutoro sensor uye yekumhanyisa control unit. Magnetoelectric speed sensor inoshandiswa kutarisa shanduko yeinjini yedhiziri uye kuburitsa AC voltage inobuda zvakaenzana. Iyo sensor sensor inoshandiswa kuona shanduko yeinjini yedhiziritakura uye uishandure kuita DC voltage kubuda zvakaenzana. Iyo yekumhanyisa control unit ndiyo musimboti wegavhuna wemagetsi, iyo inogamuchira inobuda voltage siginecha kubva kune yekumhanyisa sensor uye inotakura sensor, inoishandura kuita yakaenzana DC voltage uye inoienzanisa neiyo yekumhanyisa kuseta voltage, uye inotumira mutsauko mushure mekuenzanisa iyo actuator sechiratidzo chekutonga. Zvinoenderana nechiratidzo chekudzora cheiyo actuator, iyo oiri yekudzora nzira yeinjini yedhiziri inodhonzwa nemagetsi (hydraulic, pneumatic) kuti iwedzere kana kuderedza mafuta.
Kana iyo injini yedhiziri yakawedzera kamwe kamwe, iyo inobuda voltage yeyekuremerwa sensor inotanga kuchinja, uyezve inobuda voltage yeinjini yekumhanyisa inochinjawo zvinoenderana (iyo tsika dzese dzinodzikira). Iwo maviri ari pamusoro akaderedzwa masaini masaini anofananidzwa neyakagadzikwa yekumhanyisa voltage muyekumhanyisa control unit (yakashata chiratidzo kukosha kweiyo sensor ishoma pane yakanaka chiratidzo kukosha kweiyo set speed voltage), uye iyo yakanaka voltage chiratidzo inobuda, uye iyo inobuda axial refueling kutungamira inotenderedzwa mu actuator kuti iwedzere kutenderera kwemafuta ekupainjini yedhiziri.
Kusiyana neizvi, kana mutoro weinjini yedhiziri ukangoerekana wadzikira, iyo inobuda voltage yeyekuremerwa sensor inotanga kuchinja, uyezve inobuda voltage yeinjini yekumhanyisa inochinjawo zvinoenderana (maitiro anowedzera). Iwo maviri ari pamusoro akakwira masaini masaini anofananidzwa neyakagadzikwa yekumhanyisa voltage mune yekumhanyisa control unit. Panguva ino, iyo yakashata chiratidzo kukosha kweiyo sensor yakakura kupfuura iyo yakanaka chiratidzo kukosha kweiyo set speed voltage. Iyo yakaipa voltage chiratidzo cheiyo yekumhanyisa control unit inobuda, uye inobuda axial mafuta ekudzikisa nzira inotenderedzwa muactuator kudzikisa kutenderera kwemafuta eiyoinjini yedhiziri.
Izvo zviri pamusoro ndiyo nheyo yekushanda yemagetsi gavhuna wedhiziri jenareta set.
