Chii chinonzi sensor yemotokari yecamshaft
Youdaoplaceholder0 Automotive camshaft position sensor (CPS) mudziyo unoshandiswa kuona nzvimbo neAngle ye camshaft, zvichipa zviratidzo kuECU (Engine Control Unit) kuti idzore ma key engine parameters akadai se ignition timing, fuel injection timing, uye detonation control .
Basa guru
Kuisa cylinder panzvimbo: Nekuona nzvimbo ye camshaft, nzvimbo yepakati ye compression top dead (BTDC) yepiston yekutanga ye cylinder inoonekwa kuti inokwanisa kuisa mafuta zvakanaka uye kudzora kupisa.
Chiratidzo chinopindirana: Sechiratidzo chikuru chekudzora kupisa, chinoita kuti sirinda yega yega yeinjini ishande zvakatevedzana.
Musimboti wekushanda
Kugadzira zviratidzo: Sensor ine light-emitting diode (LED) uye phototransistor mukati. Kuburikidza nemaburi anotumira chiedza uye zvikamu zvinodzivirira chiedza zvedhisiki rezviratidzo, zviratidzo zvepulse zvepamusoro nepazasi zvinogadzirwa zvakasiyana.
Rudzi rwechiratidzo
Chiratidzo cheNe: Chinoratidza nzvimbo yecrankshaft uye chinoburitsa mapulse mazana matatu nemakumi matanhatu pakuchinja kwese.
Chiratidzo cheG: Chinoratidza nzvimbo yecamshaft, chichiburitsa mapulse matanhatu pakuchinja (zvinoenderana neAngle yekutenderera kwecrankshaft ye120°).
Mhando dzakajairika
Rudzi rwemagetsi: Kushandisa zvinhu zvinonzwa chiedza kuona maburi anotumira chiedza padhisiki rechiratidzo.
Rudzi rwemagetsi ekugadzira: Rwakakamurwa kuva rudzi rweHall (chiratidzo cheamplitude chakagadzika) uye rudzi rwemagnetoelectric (amplitude inosiyana zvichienderana nekumhanya kwekutenderera).
Mhedzisiro yekukanganisa
Zviratidzo zvekutadza: Zvinogona kukonzera kuti injini itadze kutanga, simba riderere, kushandiswa kwemafuta kuwedzere kana kugogodza.
Mhando dzakajairika: Semuenzaniso, Audi Q5 ya2015 ine ma camshaft maviri uye inoda masensa maviri ekutarisa akasiyana.
Kana sensor ye camshaft yemotokari ikatadza kushanda zvakanaka, zviratidzo zvakaita sekuoma kutanga, kudzikira kwesimba, kuwedzera kwekushandiswa kwemafuta, kudedera kwemuviri, uye rambi rekunyevera richitanga kushanda zvinowanzoonekwa. Zvinoratidzwa seizvi:
Youdaoplaceholder0 Kutanga injini zvisina kujairika: Injini inotadza kubatidza kana kuti inonetsa kutanga. Zvinogona kutora kuedza kakawanda kuti zvibudirire. Izvi zvinogona kuitika mumamiriro einjini anotonhora uye anopisa.
Youdaoplaceholder0 Dambudziko remagetsi: kumhanyisa mota zvisina simba, kunonoka kupindura kwemagetsi, uye kushaya simba panguva yekutyaira, kunyangwe pamwe nekudedera kwemuviri.
Youdaoplaceholder0 Kuderera kwekushandiswa kwemafuta: Kushandiswa kwemafuta kwakawedzera zvakanyanya nekuda kwekusakwanisa kweECU kudzora huwandu hwemafuta anoshandiswa, zvichikonzera kupiswa kwemafuta kusina kukwana.
Youdaoplaceholder0 Kushanda kusina kugadzikana : Kumhanya kweinjini hakuna kugadzikana uye kudedera kunoonekwa kana isingaiti. Kudedera kunowedzera kana paine mutoro wakawanda. Dzimwe mota dzinogona kusangana nekumhanya-mhanya kwekutyaira kana kumira kamwe kamwe padzinenge dzichidziya.
Youdaoplaceholder0 Chiratidzo chekutadza : Mwenje wekutadza kweinjini padashboard (senge makodhi ekutadza eOBD P0340-P0344) unoramba wakabatidzwa nguva dzese, zvichiratidza kuti sisitimu yaona chiratidzo chisina kujairika.
Kana zviratidzo zviri pamusoro zvikaitika, zvinokurudzirwa kuti injini iongororwe uye igadziriswe nenguva kuti injini isarambe ichipera.
Kana sensor ye camshaft position yakundikana, mota haichagoni kufamba zvakanaka. Kutyaira nekumanikidza kunogona kukonzera kukuvara kukuru kuinjini uye njodzi dzinogona kuitika dzakadai sekumira kwemotokari panguva yekutyaira. Kugadziriswa nekukurumidza kunodiwa.
Mhedzisiro yezvikanganiso pakukwanisa kutyaira
Sensor yenzvimbo ye camshaft chikamu chikuru chesystem yekudzora injini, ine basa rekupa masaini echikamu che camshaft kuECU (Electronic Control Unit) kuti inyatso dzora kutevedzana kwekupisa, nguva yekupinza mafuta, uye kudziviswa kwekuputika. Kana yakuvara, ECU haigone kuziva nzvimbo yecylinder nemazvo, zvichikonzera kutadza kudzora injini uye mota kusakwanisa kuramba ichishanda zvakanaka. Zvinoratidzwa seizvi:
Youdaoplaceholder0 Zvakaoma kutanga kana kutadza kutanga: Mushure mekukanganisa kwesensa, ECU inofanirwa kuvimba nechiratidzo chenzvimbo yecrankshaft kuti ione zvisina kunanga nzvimbo yecamshaft, zvichikonzera kunonoka kwekubatidza uye kupinza mafuta. Munguva yekutanga kutonhora, kuedza kakawanda kunogona kudiwa kana kutokundikana zvachose kunogona kuitika.
Injini inomira kamwe kamwe panguva yekutyaira: Kunyanya kana injini ichipisa kana kuti ine mutoro wakawanda, injini inogona kudzima zvisingatarisirwi nekuda kwekusagadzikana kwekudzora, zvichiwedzera njodzi yetsaona.
Youdaoplaceholder0 Simba shoma rinobuda: ECU ichapinda mumodhi yekudzivirira kukanganisa (modhi yekukamhina), ichideredza kumhanya kwemotokari (senge kusvika 80km/h) uye ichimisa mamwe mabasa, zvichikonzera kumhanyisa kusina simba uye kuoma kukwira makomo.
Zviratidzo zvinowanzo konzerwa nekusashanda zvakanaka
Kana sensor yenzvimbo yecamshaft yakuvara, mota ichabva yaratidza zviitiko zvinotevera zvinoonekwa, izvo zvinosimbisa zvakare kusakwanisika kwekutyaira:
Youdaoplaceholder0 Kumhanya kusina kugadzikana uye kuzununguka kwakanyanya : ECU inotadza kurongeka nguva yekuvhurwa nekuvhara kwevharuvhu, zvichikonzera kusawirirana pakati pehuwandu hwemuchina wekupinza nehwekubuda. Injini iri mumamiriro akafanana ne "silinda iri kushaikwa", ine kuchinja kukuru kwekumhanya kwekutenderera.
Youdaoplaceholder0 Kuora kwekushandisa mafuta: Nguva isiriyo yekupinza mafuta inotungamira mukutsva kusina kukwana, zvichiwedzera kushandiswa kwemafuta ne10% kusvika 15%, uye utsi hutema hunogona kubuda mupombi yekuburitsa utsi panguva imwe chete.
Chiedza chekukanganisa chinoramba chakabatidzwa: dashboard icharatidza yambiro yekukanganisa kweinjini (senge kodhi P0011 kana P0340), zvichiratidza kusagadzikana kwesystem.
Njodzi yekutyaira nechisimba
Kana dambudziko rikasatariswa uye mota ikaramba ichityaira, zvinotevera zvinogona kuitika.
Kukuvadzwa kweinjini yeYoudaoplaceholder0: Nguva isiriyo yekupisa inogona kukonzera kugogodza kana kudzoserwa kwe crankshaft. Kushanda kwenguva refu kunogona kukanganisa zvikamu zvepakati zvakaita semapistoni netsvimbo dzekubatanidza, zvichiwedzera zvakanyanya mari yekugadzirisa.
Youdaoplaceholder0 Kukundikana kwesystem yekuburitsa mweya: Kupisa kusina kukwana kunokonzera kuburitsa kweCO neHC kwakawandisa, izvo zvinogona kuvharira chinoshandura mhepo chetatu-nzira uye kutyora mitemo yekudzivirira zvakatipoteredza.
Youdaoplaceholder0 Njodzi dzekuchengetedza dzinowedzera: Kumira kana kukanganiswa kwemagetsi paunenge uchityaira zvinogona kukanganisa zvakananga masisitimu akadai sekubatsira mabhureki nekubatsira kutungamira, zvichikonzera njodzi kuchengetedzeka kwekutyaira.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
