Sei pane inopisa high revs
Zviri mukati
Iyo idle modhi (XX) yeinjini yemotokari ine accelerator yakaburitswa uye kuendesa munzvimbo isina kwayakarerekera pane ese mota, kunze kweakare, inodzorwa nemidziyo yakaparadzana uye inofanirwa kugadzikana. Kunyanya neinjini inodziya yakazara, kana mamiriro ese eiyo chaiyo dosing yemusanganiswa wemafuta anogadzirwa.
Iko kumhanya kwekutenderera kwe crankshaft pamakumi maviri inogadziriswa inovaka, iko kurongeka kwekuchengetedza kwayo kunoratidza kushanda kwechikamu chechinhu.
Nzira yekuziva sei kuti idle speed yakatanga kuyerera
Cyclic kana chaotic shanduko mukumhanya kwekutenderera inoonekwa zvakajeka nekuita kwetachometer tsono kana nenzeve. Chero kuchinja kunooneka hakugamuchirwi. Injini dzekare carburetor kana injini dzedhiziri dzisina kutonga kwemagetsi dzinogona kusangana nekusvetuka kwekumhanya kana uchichinja mitoro.
Pano, mutoro unofanirwa kutariswa kwete chete kubatanidzwa kwekutapurirana. Injini ine zvikamu zvakabatanidzwa, simba rekushandisa iro risingagari. Inogona kuva:
- mugadziri wemagetsi anoshandura mashandisirwo emagetsi kubva mujenareta, nekudaro achiisa bhandi rayo dhiraivha kubva ku crankshaft pulley;
- kufanana kwakasiyana mutoro kubva papombi yekutungamirira simba panguva yekutenderera kwayo;
- kudzvanya brake pedal, zvichiita kuti brake booster ishande;
- kushandura mhepo inogadzirisa compressor yemamiriro ekunze;
- kuchinja kwekushisa kwejini.
Mune injini dzemazuva ano kune mhinduro kuburikidza ne crankshaft position sensor. Iyo yemagetsi control unit (ECU) inocherekedza mutsauko uripo pakati pekumhanya kwakaiswa muchirongwa uye nekumhanya chaiko, mushure mezvo kupihwa kwekuwedzera mhepo, mafuta, kana shanduko yenguva yekubatidza inoenderana nemamiriro ezvinhu.
Asi kana pane malfunctions muhurongwa, saka kutonga kwehuwandu hakuna kukwana, kana mutongi haana nguva yekushanda nekukurumidza kuchinja, injini inoshandura kukurumidza, kuzununguka uye twitches.
Chii chinokonzera yakakwirira RPMs pane inopisa injini?
Iwe unogona kuenzanisa zvikonzero zvekuwedzera kwekumhanya kune ese mota. Idzi ndidzo shanduko mukuumbwa kwemusanganiswa, matambudziko nemoto kana chikamu chemuchina.
Kukanganisa kunofanirwa kutsanangurwa kune yega yega sangano rekufambiswa kwebasa, primitive spray of peturu mu carburetor, inodzorwa inopihwa mune yemagetsi jekiseni system kana dizeli injini yemafuta magungano.
Carburetor ICE
Chinhu chakasiyana cheinjini dzinopisa mukati ndeyekushaikwa kwemhinduro pakumhanya. Iyo carburetor inoburitsa imwe chiyero chemusanganiswa zvichienderana nekumhanya kwekuyerera kwemhepo inopfuura nayo.
Iyi kumhanya inoenderana nehuwandu hwekutenderera, asi hazvifanirwe kumirira mhinduro chaiyo kune zvese zvinhu. Iyo mota inogona kurasikirwa nekumhanya kubva kune chero mutoro muchimiro chekusashanda kana kubatana kwevatengi, uye muripo haupihwe.
Izvo zvakapesana nemamiriro ezvinhu zvakare zvinogoneka, kana kumukira kwakakwira, asi iyo carburetor idle system inogona kuita nenzira chete - kuwedzera mamwe musanganiswa, kuchengetedza uku kwakawedzera kumukira. Nokudaro, zvinenge zvose zvinokanganisa kukurumidza kwekutenderera.
Kazhinji kazhinji, kushanda kweautonomous XX system kunokanganiswa nekuda kwekuvhara mu carburetor. Kuedza kugadzirisa kunotungamirira kukushanda kusina kugadzikana uye kuwedzera kwakanyanya kwezvinhu zvinokuvadza mumhepo, uye pakufamba injini inogona kumira panguva isina kukodzera. Sezvineiwo, carbureted injini dzinenge dzaenda.
Injector
Ichiona kuwedzera kwekumhanya, iyo ECM ichapa murairo wekudzikisa iwo. Mugero wemhepo uchavharwa nemutongi wenguva dzose, asi masimba ayo anogumira.
Mamiriro ezvinhu akafanana nekuyerera kwemhepo yakawandisa ichipfuura nzira yekudzora. Iyo sisitimu ichawedzera huwandu hwakakodzera hwepeturu, kumhanya kuchawedzera. Hazvibviri kugadzirisa kukanganisa, chiteshi XX chatovharwa zvachose.
Chiratidzo chekukanganisa chichaonekwa, mutongi achapinda mune yekukurumidzira nzira yekuchengetedza yakawedzera kukurumidza, sezvo isina kuchengetedzeka kumisa injini.
Injini yedhiziri
Diesel zvakare akasiyana, kubva kune akareruka emafuta masisitimu ane mechanical pombi, kune azvino, emagetsi anodzorwa nezviratidzo zveakawanda sensors, asi hwaro hwezvinhu zvese kuyerera kwemhepo kuyerwa neECU.
Chikonzero chinowanzokonzera kukanganisa ndeye recirculation valve, yakagadzirirwa kupa chikamu chekutsvaira kudzokera kune kutora. Mamiriro ainoshanda mairi anokonzera kusvibiswa nekukundikana.
Zvimwe zvinokanganisa zvinogonekawo, high pressure pump, sensors, regulators, intake manifold, majekiseni. Kuongororwa kwakaoma kunodiwa.
Nzira dzekugadzirisa dambudziko
Kazhinji hazvisi zvakaoma kubvisa kukanganisa, nguva yakawanda inoshandiswa pakutsvaga kwayo nekuda kwezvikonzero zvakasiyana-siyana.
Misa mweya inoyerera sensor
Iyo DMRV inogona kupa kuverenga kwakakanganiswa, kuunza kukanganisa mukuverenga kwekombuta. Iyo yekupedzisira inokwanisa kudzivirira nyore nyore kunyengera, asi kazhinji mukati mediki diki.
Ipapo iye achangodzima zviri pachena kuti yakanganisa sensor, tanga mutemo maererano nekuverenga kwevamwe vese, kuwedzera kumhanya kweXX uye kuseta kodhi yekukanganisa.
Iyo yakanganisa DMRV inotariswa zvinoenderana neiyo scanner data mumamodhi akasiyana, chiratidzo chayo chinofanira kuenderana neyakajairwa seti. Izvo zvakafanana zvinogona kuitwa ne multimeter, asi kwete mune ese mota. Iyo sensor inoda kutsiviwa. Dzimwe nguva zvinokwanisika kuishambidza uye kuidzorera, asi haufaniri kugara uchitarisira.
РХХ sensor
Muchokwadi, iyi haisi sensor, asi actuator. Iyo ine vharafu yemhepo inodzorwa neinotsika mota.
Matambudziko anoitika nekuda kwekusvibiswa kweiyo actuator, iyo throttle musangano uko regulator yakaiswa mu bypass chiteshi, pamwe nekupfeka kwemagetsi. IAC inoshandurwa kuva itsva, uye musangano we throttle unofanira kubviswa uye kunyatsoputirwa.
DPDZ
Iyo throttle position sensor inogona kuve nedhizaini muchimiro cheiyo nyore potentiometer ine marasha mugwagwa uye inotsvedza. Iyi michina inopera nekufamba kwenguva uye inotanga kupa mabreak uye kukanganisa.
Hazvidhuri, zviri nyore kuongororwa ne scanner uye nekukasira kuchinjwa. Dzimwe nguva zvinokwanisika kudzorera kushanda nekugadzirisa nzvimbo kuitira kuti damper yakavharwa ipe zero yakajeka kune kombiyuta.
Throttle
Mhepo yekupa mhepo ine throttle inowanzosvibiswa, mushure mokunge iyo damper haivhari zvachose. Izvi zvakaenzana nekutsikirira zvishoma gasi pedal, izvo zvinotungamira mukuwedzera kwekukurumidza.
Uyezve, hapana chikanganiso chinogadzirwa, sezvo TPS ichiratidzirawo kuvhurwa kudiki. Mhinduro ndeyekugeza throttle pipe nevanochenesa. Dzimwe nguva chinhu chimwe chete chinoitika nekuda kwekupfeka uye kubvaruka. Ipapo gungano rinotsiviwa.
Injini yekupisa sensor
Kuumbwa kwemusanganiswa kunoenderana nekupisa kwemota. Kana iyo sensor inoenderana ichishanda nekukanganisa kukuru, iyo ECU inogadzirisa izvi sezvisina kukwana kudziya, kuwedzera kukurumidza kuita.
Nokuenzanisa tembiricha chaiyo nekuverenga kwe scanner, zvinokwanisika kuziva uye kuramba mafuta edhiziri, mushure mezvo zvese zvinosarudzwa nekutsiviwa kusingadhuri.
Kudya zvakawanda
Iyo yese yekutora turakiti inofanirwa kuvharwa, sezvo paine vacuum mairi kana iyo throttle yakavharwa. Chero kuputika mumagaskets kana zvinhu zvezvikamu zvinotungamirira kune kusvetwa kwemhepo isingaverengeki, kukanganisa uye kuwedzera kwekukurumidza.
Diagnostics inodiwa uchishandisa jenareta rehutsi kana bvunzo yekabhoni, kureva, nekuteura nzvimbo dzinofungirwa nemasprayiri anopisa.
ECU
Kashoma, asi zvikanganiso zveECU zvinoitika, kubva mukuchembera kana kupinda kwemvura muchimiro chayo chakavharwa. Iyo unit inogona kudzoreredzwa ne soldering kune nyanzvi, kuchenesa vanobatika uye kutsiva zvinhu.
Asi kazhinji inongotsiviwa neitsva kana inozivikanwa yakanaka kubva kumota disassembly. Muchokwadi, kutadza kweECU kunotungamira kune zvakakomba kuratidzwa pane kuwedzera kwekukurumidza.
Hazvidikanwi kutyaira uchimhanya zvakanyanya. Iyi imodhi yekukurumidzira, iyo inogona kutungamira kune nyowani kuparara kweinjini. Asi kusvika panzvimbo yekugadzirisa zvinotenderwa uri wega.
