Chii chinonzi Electronic Throttle Control uye Basa Rayo?
Electronic Throttle Control (ETC) tekinoroji iri mumotokari dzemazuva ano inodzora kuvhurwa kwevharuvhu yegesi (throttle) nemagetsi, isingachashandisi tambo dzemakanika sedziri mumasystem ekare ethrottle. Mumotokari dzekare, pedal yegesi yakabatana zvakananga ne throttle body kuburikidza netambo (throttle cable), muETC kubatana ikoko kunotsiviwa nema sensors, electronic control module (ECU/ECM), uye electric motor actuator. Chinangwa chikuru ndechekuita kuti kutonga kwesimba reinjini kuve kwakanyatsojeka, kunoshanda, uye kuve nyore kubatanidza nezvinhu zvakasiyana-siyana zvekuchengetedza uye kunyaradzwa.
Munguva yeinjini dzinoshandisa mafuta uye zvinhu zvakaoma zvekubatsira kutyaira, ETC yave chinhu chakakosha nekuti inobvumira komputa yemotokari "kunzwisisa" zvinodiwa nemutyairi kuburikidza nekuisa pedal yepedal, yozoishandura kuita throttle yakanakira zvichienderana nemamiriro einjini uye zvinodiwa nemotokari parizvino.
Kunzwisisa Kudzora Kwemagetsi
Zvichitaurwa zviri nyore, Electronic Throttle Control inzira yekudzora throttle inoshanda ichishandisa masaini emagetsi. Iyi nzira inowanzonzi drive-by-wire nekuti mutyairi haacha "fambise" throttle zvakananga netambo, asi "anotumira mirairo" kuburikidza nesensor.
Kana mutyairi akadzvanya pedal yekumhanyisa, sensor iri papedal (Accelerator Pedal Position Sensor/APPS) inoverenga kuti pedal yadzikiswa kusvika papi. Ruzivo urwu runotumirwa kuECU. ECU inobva yaverenga kuvhurwa kwethrottle kwakakodzera zvichienderana nezvinhu zvakasiyana-siyana—sekumhanya kweinjini (RPM), mutoro weinjini, tembiricha yeinjini, kana mhepo iri kutonhora kana kuti yakadzimwa, uye nzira dzekushandisa mafuta zvakanaka—yobva yarayira mota yekufambisa iri mumuviri wethrottle kuti ivhure vharuvhu yethrottle pakona chaiyo.
Nekuti zvese zvinodzorwa nemagetsi, sisitimu iyi inewo sensor yekudzora throttle position (TPS) kuti ive nechokwadi chekuti mavharuvhu anovhurika sezvakarairwa. Nemamwe mashoko, ETC inoshanda musystem yakavharwa, ichiramba ichigadzirisa chero musiyano uripo pakati pechinangwa nemamiriro chaiwo.
Zvikamu Zvikuru zveETC
Kuti zvive nyore kunzwisisa mashandiro azvo, hezvino zvinhu zvinowanikwa muElectronic Throttle Control system:
1. Chinotenderera chegesi chine sensor yenzvimbo (APPS)
Sensor iyi inotsiva waya. Mota zhinji dzinoshandisa masensor maviri (redundancy) kuti dzive dzakachengeteka, zvichibvumira ECU kuenzanisa masaini uye kuona kusagadzikana.
2. ECU/ECM (Chikamu Chekudzora Injini/Module)
Uropi hwesisitimu, kugadzirisa zvinopinda kubva kupedal, ma sensor einjini, nedzimwe sisitimu. ECU ndiyo inosarudza nzvimbo yakakodzera yekuvhura throttle yemamiriro ese ezvinhu.
3. Muviri wemagetsi unokwevera throttle
Ine vharuvhu yemagetsi, mota yemagetsi inodzora kupisa, uye sensor yenzvimbo yemagetsi (TPS). Mota iyi inofambisa vharuvhu zvichienderana nemirairo yeECU.
4. Ma sensor anotsigira
Izvi zvinosanganisira kufamba kwemhepo (MAF), kumanikidzwa kwakawanda (MAP), tembiricha yemhepo inopinda (IAT), tembiricha inotonhodza, sensor yeO2, sensor yekugogodza, nezvimwewo. Zvese izvi zvinobatsira ECU kuita sarudzo dze throttle dzakanakisa.
5. Sisitimu yekuchengetedza (yakachengeteka/yakamanikana)
Kana paine chikanganiso, sisitimu iyi inogona kudzikamisa kuvhurika kwethrottle kuitira kuti mota ikwanise kufamba zvishoma nezvishoma kuenda kunzvimbo yekugadzirisa, asi zvakadaro zvakachengeteka.
Mashandiro Ekushandisa Kudzora Throttle yeElectronic
Matanho ekushanda eETC ndeaya anotevera:
1. Mutyairi anodzvanya pedal yepeturu.
2. APPS inoshandura nzvimbo yepedal kuita chiratidzo chemagetsi (voltage/digital number).
3. ECU inoverenga chiratidzo, yobva yachisanganisa nedzimwe data dze sensor.
4. ECU inoverenga nzvimbo yekuvhura throttle (pamwe chete nehurongwa hwekupinza mafuta uye hwekubatidza).
5. ECU inotumira chiratidzo kumota ye throttle kuti ivhure vharuvhu zvichienderana nechinangwa.
6. TPS inotumira mhinduro pamusoro penzvimbo chaiyo ye throttle.
7. ECU inoenzanisa chinangwa nechacho chaicho uye inogadzirisa kana zvichidikanwa.
Maitiro aya anoitika nekukurumidza (mumamilisekonzi), saka mhinduro yepedal ichiri kungonzwika seyechisikigo.
Basa reKudzora Throttle yeMagetsi
ETC haisi kungo "tsiva tambo ye throttle." Iyi tekinoroji ine mabasa akawanda akakosha:
1. Gadzirisa mhepo inobuda zvakanaka
Injini dzepeturu dzemazuva ano dzinoshandisa zvakanyanya musanganiswa wemhepo nemafuta chaiwo. NeETC, ECU inogona kuvhura throttle nemazvo, ichipa mweya unodiwa. Mugumisiro wacho unova kupisa kwakasimba, kupindura kwakanaka kweinjini, uye kuburitsa mweya kwakadzikama.
2. Wedzera kushanda zvakanaka kwemafuta
Nekuti ECU inogona kugadzirisa kuvhurika kwethrottle zvichienderana nemamiriro ezvinhu, sisitimu iyi inobatsira kuderedza kushandiswa kwemafuta. Semuenzaniso, kana uchityaira nguva dzose mumugwagwa wakatwasuka, ECU inogona kusarudza kuvhurika kwethrottle kunoshanda zviri nani pane kungotevera "tambo yekudhonza" zvakananga.
3. Kubatanidzwa nezvinhu zvekuchengetedza (kudzora kudhonza & kudzora kugadzikana)
ETC inobvumira masisitimu ekutonga kudhonzwa (TCS) uye ekudzora kugadzikana (ESC) kuderedza simba reinjini pasina kungovimba nekubhureka chete. Kana vhiri rikatsvedza, ECU inogona kuvhara zvishoma throttle ipapo ipapo, zvichiita kuti mota igare zvakanaka uye ideredze njodzi yekurasikirwa nekudzora.
4. Inotsigira kudzora ngarava uye kudzora ngarava inochinjika
Nekushandisa cruise control, mota inofanira kuchengetedza kumhanya kwakatarwa. Nekushandisa ETC, ECU inongogadzirisa throttle otomatiki kana zvichidikanwa. Nekushandisa adaptive cruise control (ACC), system inogona kutogadzirisa kumhanya kuti itevere mota iri pamberi, zvese izvi zvinoda throttle inodzorwa nekombuta.
5. Inogadzirisa kukurumidza uye inowedzera nyaradzo
Nekuti ECU inogona "kusefa" zvinopinda mudhiraivha, kumhanyisa mota kunogona kuitwa kuti kuve nyore. Izvi zvinoonekwa kana mota ichifamba zvishoma nezvishoma mumotokari kana pakupaka mota, uko kudzora pedal kunogona kuitwa kuti kuve kwakanaka uye kusanyanya kuvhiringika.
6. Kuwedzerwa muripo wemutoro (AC, alternator, steering yemagetsi)
Kana AC yakabatidzwa, mutoro weinjini unowedzera uye kumhanya kweinjini kunowanzodzikira. NeETC, ECU inogona kugadzirisa yega throttle open kuti irambe yakagadzikana pasina mutyairi achifanira kudzvanya accelerator pedal.
7. Gadzirisa kumhanya kwekusashanda nemazvo
Pane mamwe masisitimu ekare, idle inodzorwa neIdle Air Control Valve (IAC). Pamotokari dzakawanda dzeETC, idle inogona kudzorwa nekuvhura throttle zvishoma, zvichiita kuti zvikamu zvive nyore uye kuita kuti control ive yakanyatsojeka.
8. Inotsigira nzira dzekutyaira (Eco/Normal/Sport)
Mota zhinji dzemazuva ano dzine nzira dzekutyaira. Nzira idzi dzinowanzo shandura mapedal mapping. Semuenzaniso, Eco mode inoita kuti pedal response ive nyoro kuti ichengetedze mafuta, nepo Sport mode inoita kuti throttle ive nesimba kuti ikurumidze kupindura. Izvi zviri nyore kuita nekuti throttle inodzorwa neECU.
