Chii chinonzi sensor ye crankshaft yemotokari?
Iyo crankshaft sensor, inozivikanwawo se crankshaft position sensor, i core sensor mu engine electronic control system. Inonyanya kushandiswa kuona nzvimbo yekutenderera ye crankshaft, top dead center signal ye piston, uye kumhanya kweinjini, uye inopa data rakakosha ku engine control unit (ECU) kudzora nguva yekupisa uye nguva yekuisa mafuta. Nheyo yekushanda ye crankshaft sensor inoenderana nerudzi rwayo, iyo inonyanya kusanganisira magnetic-electric induction type, Hall effect type, uye photoelectric type. Iyo magnetic-electric induction type inogadzira masaini kuburikidza ne electromagnetic induction, iyo Hall effect type inoona nzvimbo uchishandisa Hall voltage changes, uye iyo photoelectric type inotumira ruzivo kuburikidza ne light hole obstruction uye photoelectric signal conversion; ma sensor aya anowanzo shanda pamwe chete ne camshaft position sensor kuti aone nemazvo crankshaft angle uye angular velocity, kuve nechokwadi chekuti ignition uye fuel injection time yakarurama. Basa rayo rakakosha, kwete kungoona nguva yekupisa uye fuel injection, asiwo kuongorora crankshaft angle kushanduka kuti ione misfire yeinjini uye kupa rutsigiro rwe data re idling control uye fuel evaporation control. Mukugadzirisa mota, zvikanganiso zvinowanzoitwa ne crankshaft sensor zvinosanganisira kurasikirwa nechiratidzo kana kupindira, izvo zvinogona kukonzera matambudziko mukutanga kweinjini, kusagadzikana kwekushanda, kana kurasikirwa nemagetsi; nzira dzekuona dzinowanzo sanganisira kutarisa kubatana kwewaya, masaini emagetsi, kana kukosha kwekudzivirira kwesensa kuti ive nechokwadi chekuti inoshanda zvakanaka.
Zvikanganiso zvinowanzoitwa ne crankshaft sensor zvinosanganisira kurasikirwa nesignali kana kukanganiswa, izvo zvinogona kukonzera matambudziko mukutanga kweinjini, kusagadzikana kwekushanda, kana kurasikirwa nemagetsi; nzira dzekuongorora dzinowanzo sanganisira kutarisa kubatana kwewaya, masaini emagetsi kana ma sensor resistance kuti ive nechokwadi chekuti inoshanda zvakanaka.
Kukundikana kwe crankshaft sensor kunogona kukonzera zviratidzo zvakaita sekukundikana kweinjini kutanga, kutadza kubatidza injini zvisina tsarukano uye nguva yekupinza mafuta, kuwedzera kwekuzunguzika kweinjini uye kudzimwa kwekumhanya, nezvimwewo, uye zvakakosha kuongorora nekuitsiva nenguva.
Zviratidzo zvekutanga zvisina kujairika uye kuvhiyiwa
Kukundikana kwe crankshaft sensor kunokanganisa zvakananga nguva yekupisa injini uye nguva yekuisa mafuta, uye kunoratidzwa seizvi:
Kuoma kutanga kana kutadza kutanga: Nekuda kwekutadza kwesensa kupa chiratidzo chekumira kwecrankshaft, ECU (injini control unit) haigone kudzora kubatidza nekupinza mafuta, zvichikonzera nguva yekutanga kweanopfuura masekondi mashanu kana kutadza kubatidza kakawanda, uye muzviitiko zvakakomba, magetsi ane simba guru nekupinza mafuta zvinodzimwa.
Kudedera kweinjini uye kurasikirwa kwesimba:
Kusagadzikana kwemotokari: Kumhanya kweinjini kunochinja-chinja zvisina kurongeka pakati pe600-1200 rpm, uye ruzha rwechidhiraivho rwuri pachena.
Kumhanya kushoma: Kumhanya kweinjini kunonetsa kudarika 3000 rpm pakukwira, uye pombi yekubuda nemhepo inogona kuburitsa ruzha kana utsi huchena (nekuda kwekupisa kusina kukwana).
Njodzi yekudzima injini panguva yekutyaira: Kumbomira kwesimba kamwe kamwe kunogona kuitika panguva yekutyaira uchimhanya zvakanyanya, uye ECU inopinda mumodhi yekudzivirira uye inodzima nechisimba, izvo zvine njodzi huru.
Mabasa ehurongwa uye zviratidzo zvekunyevera
Kukundikana kwesystem yemagetsi:
Mabasa akadai sekudzora cruise, kumisa otomatiki kutanga, uye kubhureki kwe exhaust zvinomiswa zvakananga.
Chiedza chemagetsi chinoramba chakabatidzwa kana kupenya, uye mamwe mamodheru anokonzeresa maaramu ekubatanidza eEPS/ABS.
Utsi husina kujairika uye kushandiswa kwemafuta: Utsi huchena hunoramba huchibuda hune hwema hwakaita sepeturu hunobuda, sensor yeokisijeni inoshuma kuti pane kodhi yekusawirirana kwemafuta musanganiswa, uye kushandiswa kwemafuta kunowedzera zvakanyanya.
Kusiyana kwezviratidzo zvekukanganisa
Chikanganiso chidiki: Mota haina simba pakutyaira ichikwira, mhinduro yeaccelerator inononoka, asi mashandiro emagetsi haachinji zvakanyanya.
Dambudziko guru: Haikwanise kutanga zvachose, uye mota inogona kuita ruzha rwepiston ichirova vharuvhu (mumhando dzekare).
Kana sensor yenzvimbo ye crankshaft yeinjini ikatadza kushanda, mota inoratidza zviratidzo zvakaita sekunge mota yatanga zvisina kujairika, kurasikirwa nemagetsi, kuzununguka kwakanyanya, uye rambi remagetsi richibatidzwa, seizvi:
Kutanga kusina kujairika
Kurasikirwa nechiratidzo che sensor kunokonzera kusagadzikana kwekupisa uye nguva yekupinza mafuta, zvichiratidzwa seizvi:
Dambudziko rekutanga nechando: Zvinoda kuyedza kakawanda kuti ibatidze, uye kana zvanyanya kuoma, haigone zvachose kutanga.
Kuwedzerwa kwenguva yekutanga: Nguva yekutenderera kweinjini yakareba zvakanyanya, uye panogona kunge paine ruzha rusina kujairika.
Matambudziko ekutyaira
Kukanganisa uku kunokonzera kusawirirana kwemagetsi, uye zviratidzo zvinowanzoonekwa zvinosanganisira:
Kumhanya kusina kusimba: Mhinduro yekukwira kana kudarika inononoka, uye pedal yekumhanyisa inofanira kuderedzwa zvizere kuti iwedzere kumhanya.
Kudedera kusina kumira: Injini inodedera zvine simba kana yamiswa, uye chidhiraivho kana chigaro zvine ruzha rwuri pachena.
Kubuda kweutsi huchena: Kupisa kusina kukwana kunoita kuti utsi huchena hubude mupombi yekuburitsa utsi. Kuwedzera kwekushandiswa kwemafuta: Nekuda kwekudzora mafuta zvisina kunaka, kushanda zvakanaka kwemafuta kunoderera.
Kukundikana kwesystem yemagetsi
Zviratidzo zve sensor zvisina kujairika zvinokonzeresa ketani yekuita:
Mwenje wekutadza unobatidzwa: Mwenje wekutadza kweinjini padashboard unogara wakabatidzwa kana kupenya.
Kukundikana kwebasa: Masisitimu ekudzora cruise uye exhaust braking haagone kushandiswa.
Njodzi yekudzima injini: Injini inogona kungoerekana yadzima ichityaira ichimhanya zvakanyanya, zvichikonzera njodzi dzekuchengetedza.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
