Basa rekunzwa chinzvimbo cheCamshaft.
Basa re sensor yemota ye camshaft position:
1, sensor yenzvimbo yecamshaft ndeyekuunganidza chiratidzo cheAngle chinoshanduka checamshaft, uye kuisa muyuniti yekudzora yemagetsi (ECU), kuitira kuti ione nguva yekupisa uye nguva yekuisa, kuitira kuti intake uye exhaust zviwanikwe;
2, kuitira kuti iite sequentially fuel injection control, ignition time control uye deflagration control. Pamusoro pezvo, camshaft position signal inoshandiswa kuziva nguva yekutanga yeignition injini painotanga. Nekuti camshaft position sensor inogona kuziva kuti ndeipi cylinder piston iri kuda kusvika TDC, inonzi cylinder identification sensor;
3, chimiro nepfungwa yekushanda kwe sensor ye camshaft position ne crankshaft position sensor zvakafanana, uye zvinowanzoiswa pamwe chete, asi nzvimbo yekuisa yemodhi yega yega yakasiyana, asi inofanira kuiswa munzvimbo ine hukama chaihwo hwekutumira ne crankshaft, senge crankshaft, camshaft, flywheel kana distributor;
4, ingoshandisa crankshaft sensor ECU system ine maitiro akakosha ekusiyanisa kubatidza, kusiyanisa kutevedzana kwekubatidza kwecylinder, zvakasiyana nenzira yekushandisa ma sensor maviri ndiko kuti, pfungwa yakakurumbira ndeye "kuverenga", crankshaft inomhanya "1-3-4-2" muhuwandu hwakatarwa hwekutenderera. Saka purogiramu inogona "kuverenga" ma cylinders akasiyana ekupfura paAngle imwe chete yecrankshaft, saka sensor imwe chete yakakwana.
Sensor yenzvimbo yeCamshaft inozivikanwawo se cylinder identification sensor, kuti isiyanise kubva ku crankshaft position sensor (CPS), camshaft position sensor inowanzo miririrwa neCIS. Basa re sensor yenzvimbo yecamshaft nderekuunganidza chiratidzo chenzvimbo ye valve camshaft uye kuiisa kuECU, kuitira kuti ECU igone kuziva pakati pe cylinder 1 compression, kuitira kuti iite sequential fuel injection control, ignition time control uye deflagging control. Pamusoro pezvo, camshaft position signal inoshandiswa kuziva nguva yekutanga yeignition injini painotanga. Nekuti camshaft position sensor inogona kuziva kuti ndeipi cylinder piston iri kuda kusvika kuTDC, inonzi cylinder identification sensor.
Kushanda kusina kunaka kwesensa yeCamshaft
01 Kuomerwa nekutanga mota
Dambudziko rekutanga mota rinoratidza pachena kuti injini ine dambudziko re camshaft sensor. Camshaft position sensor ndiyo inosarudza kuti injini ine ignition sequence yakaita sei. Kana ikatadza kushanda, ignition sequence inobuda mugwara, zvichiita kuti injini itange zvakaoma uye dzimwe nguva isingatangi zvachose. Izvi hazvingokanganisi mashandiro ekutanga kwemotokari chete, asiwo zvinogona kukonzera kukuvara kwakanyanya kuinjini. Saka, kana zvaonekwa kuti mota yakaoma kutanga, unofanira kutarisa kana camshaft sensor iri kushanda nemazvo nekukurumidza.
02 Kusasimba kwekukurumidzira
Kusakwanisa kwemotokari kumhanya kunoratidza pachena kukuvara kwesensa ye camshaft. Kana sensa ye camshaft ikakundikana, ECU haigone kuona nemazvo shanduko yenzvimbo ye camshaft. Izvi zvinokanganisa masisitimu ekupinda nekubuda kweinjini, zvichikonzera kudzikira kwekupinda nekubuda kwesensa yepedyo. Nekuti zvinhu izvi zvakakosha hazvishande nemazvo, mota ichaneta painomhanya, kunyanya kana kumhanya kuri pasi pe2500 RPM.
03 Kuwedzera kwekushandiswa kwemafuta
Kushandiswa kwemafuta akawanda chiratidzo chekutadza kushanda kwesensa ye camshaft. Kana sensa ye camshaft isina kunaka, sisitimu yemafuta yemotokari inogona kusashanda zvakanaka, zvichiita kuti nozzle kana injector ipfapfaidze mafuta zvisina kunaka. Kushandiswa kwesensa uku hakungoiti kuti mota ishandise mafuta chete, asiwo kunogona kukonzera kuti kumhanya kweinjini kusashande zvakanaka, uye mota iite seisina simba. Saka, kana mafuta emotokari akawedzera zvisina kujairika, zvinogona kuva chiratidzo chekuti sensa ye camshaft haina kunaka.
04 Chiedza chemotokari
Mwenje wemotokari unowanzoreva kuti masensa akawanda anogona kunge asiri kushanda zvakanaka. Kunyanya kana sensor yenzvimbo yecamshaft yakakuvara, chiitiko ichi chinonyanya kuoneka. Masensa ecamshaft anowanzo kuve masensa eHall ane waya nhatu, anosanganisira tambo dzemagetsi dze12v kana 5v, tambo dzesignal uye tambo dzinobata. Kana plug yabviswa uye injini yatanga, kana pasina magetsi esignal akabuda pakati pemutsetse wesignal ne base line, izvi zvinowanzoreva kuti sensor yakakuvara. Muchiitiko ichi, mwenje wemota unogona kuvhenekesa mutyairi kuti aite ongororo yakadzama.
05 Muviri unodedera zvisina kujairika
Kudedera kwemuviri kusingawanzoitiki chiratidzo chekutadza kushanda kwesensa ye camshaft. Kana paine dambudziko nesensa ye camshaft, injini yemotokari inogona kusakwanisa kuverenga mamiriro ekushanda kweinjini nemazvo, zvichikonzera kushanda kweinjini kusina kugadzikana uye kudedera kwemuviri kusingawanzoitiki. Kudedera uku kunowanzoonekwa zvakanyanya kana mota iri kumhanya kana kudzikamisa kumhanya. Kuti kuve nechokwadi chekuti kutyaira kwakachengeteka, kana matambudziko akadaro awanikwa, kuongororwa kwehunyanzvi uye kugadziriswa kunofanirwa kuitwa nenguva.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
