Chii chinonzi mota phase controller
Chinodzora chikamu chemotokari chishandiso chinoshandura nguva yevharuvhu nekugadzirisa Angle yechikamu uye chinonyanya kushandiswa kugadzirisa mashandiro einjini. Basa rayo guru nderekugadzirisa nguva yekuvhurwa nekuvhara kwemavharuvhu zvichienderana nekumhanya kweinjini nemutoro wayo, nokudaro zvichiwedzera simba rinobuda uye kuchengetedza mafuta.
Maumbirwo uye musimboti wekushanda
Chinodzora chikamu chinowanzo umbwa nemuviri wechinodzora chikamu, chinodzora chikamu che camshaft, mota, nezvimwewo, uye chikamu che camshaft chinogadziriswa kuburikidza ne hydraulic system kana motor drive. Semuenzaniso, chinodzora chikamu chemagetsi chinobatanidza camshaft ne sprocket kuburikidza ne three-axis speed change mechanism, uye mota inofambisa kugadziriswa kwemusiyano wechikamu kuti iwane dynamic adjustment ye valvu timing.
Mamiriro makuru ekushandisa
Inonyanya kushandiswa muma "variable valve timing systems" (akadai seVVT), zvichibatsira pakushanda kweinjini dzakasiyana. Semuenzaniso, "intake phase regulator" inogona kuwedzera kushanda zvakanaka kwemoto, nepo "exhaust phase regulator" ichigona kuderedza kukanganiswa kwegasi rinobuda mumoto.
Mamota emota anonyanya kushandiswa kushandura maparamita eresonant circuit nekuchinja chiratidzo, zvichikonzera kuchinja kwechikamu mucarrier signal kuti igadzire phase-modulated wave. Anonyanya kushandiswa pakuchinja chiratidzo uye kutumira mumagetsi.
Basa guru
Youdaoplaceholder0 Kuchinja kwechiratidzo : Nekugadzirisa maparamita akadai se inductance uye capacitance ye resonant circuit, chikamu chechiratidzo chekutakura chinoshandurwa kuti chiwane phase modulation yechiratidzo.
Kudzora dunhu reYoudaoplaceholder0 : Inoshandiswa mumasisitimu emagetsi kudzora kugadzikana kwemagetsi, semuenzaniso, kuchengetedza voltage inobuda yejenareta pamutengo wakaenzana (senge 14V) kuve nechokwadi chekushanda kwakajairika kwemidziyo yemagetsi.
Basa rekudzivirira reYoudaoplaceholder0 : Kana magetsi ekuchaja akawandisa akaonekwa kana kuyerera kwesero kukaitika, dunhu rinomiswa nekukurumidza kudzivirira kuchaja zvakanyanya kwebhatiri kana kukuvara kwemidziyo.
Musiyano kubva kumota inodzora mota
Vatongi vemapazi vanonyanya kutarisa pakugadzirisa masaini uye kudzora macircuit, nepo vatongi vemotokari vakanyanya kutsaurira pakugadzikana kwemagetsi uye kudzivirira overcurrent mumasisitimu emagetsi. Mamiriro ekushandiswa kwezviviri izvi akasiyana, asi zvese zvinosanganisira kudzora maparameter edunhu uye nzira dzekudzivirira.
Nheyo yekushanda kwe automotive phase regulator inonyanya kushandiswa pa hydraulic system kana motor drive. Nekugadzirisa nzvimbo iri pakati pe camshaft ne crankshaft, nguva yevharuvhu (kureva, nguva iyo mavharuvhu anovhurwa uye anovharwa) inochinjwa.
Nheyo yema hydraulic phase modulators
Semuenzaniso, tora sisitimu yeOCV VVT yakaiswa padivi. Zvikamu zvayo zvikuru iphase regulator neoil control valve (OCV). Phase regulator inogadzirisa nzvimbo iri pakati pe camshaft sprocket nerotor kuburikidza ne hydraulic chamber, uye oil control valve inodzora hydraulic pressure zvichienderana nemamiriro ekushanda kweinjini. Kana mutoro wakaderera, vhara intake valve pachine nguva; kana mutoro wakakwira, nonoka kuvhara intake valve kuti ugone kuburitsa simba.
Nheyo yemutongi wechikamu chemagetsi
Chinodzora chikamu chemagetsi chinoshandisa chimiro chemativi matatu: chikamu chekutanga chakabatana necamshaft, chikamu chechipiri chinofambiswa nemota, uye chikamu chechitatu chakabatana ne sprocket. Mota inowana kudzorwa kwechikamu nekugadzirisa musiyano wekumhanya. Kana Angle yenguva yakanaka yagadziriswa, ma axes matatu anotenderera zvakaenzana. Pakugadzirisa chikamu, mota inotyaira shaft kuti ikurumidze kana kudzikira.
Mhando dzese dziri mbiri dzinoda masensa ekutarisa nzvimbo dze crankshaft ne camshaft, uye kudzora zviito zve actuator kuburikidza neECU.
Kukanganisika kwemuchina wekugadzirisa mota (kazhinji kacho kunoreva muchina wekugadzirisa mota) kunogona kukonzera voltage isina kujairika, kuoma kutanga uye mamwe matambudziko. Izvi zvinotevera ndizvo zviratidzo chaizvo nezvikonzero:
Zviitiko zvakajairika
Youdaoplaceholder0 voltage anomaly
Kugadzirwa kwemagetsi akawandisa kunogona kukonzera kuchajisa bhatiri zvakanyanya, nepo voltage ichigona kupfuura 14V, zvichiita kuti bhatiri rikurumidze kukwegura uye kutokonzera kukuvara. Kana kugadzirwa kwemagetsi kusina kukwana, voltage inogona kunge yakaderera pane 10V, zvichikonzera kuoma kwekutanga uye kumhanyisa kushoma.
Matambudziko ane chekuita nebhatiri reYoudaoplaceholder0
Kana mwenje wechiratidzo chebhatiri usina kujairika (uchigara wakabatidzwa kana kupenya), hupenyu hwebhatiri huchapfupikiswa. Muzviitiko zvakakomba, rinogona kusakwanisa kuchengetedza magetsi.
Kuderera kwekushanda kweinjini yeYoudaoplaceholder0
Kana injini ikazununguka, ikamhanya zvisina simba kana kuti ikamira zvakananga, inofanira kuongororwa uye kugadziriswa nenguva.
Chikonzero chekutadza kushanda zvakanaka
Kuchinja kwevoltage yeYoudaoplaceholder0
Kusagadzikana kwemagetsi anobuda ejenareta (sekuchinja-chinja kwekumhanya kweinjini yedhiziri uye kuchinja kukuru kwemutoro) kunoita kuti regulator igadzirise nguva nenguva, zvichiita kuti zvikamu zvikurumidze kukwegura.
Youdaoplaceholder0 Mutoro wakawandisa wemakanika
Kushanda kwenguva refu uchideredza simba remagetsi (sekunge uchingomira kana kuti mafuta anobuda munzvimbo yejenareta) kunowedzera mutoro wekushanda kwemutongi.
Youdaoplaceholder0 chikamu chekukwegura
Matransistor emukati memuchina wekutonga (akadai seFET, Darlington transistors) anopwanyika kana kuvhurwa, zvichikonzera kurasikirwa kwesimba rekutonga.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
