Kupinza tembiricha yemhepo sensor
Zviri mukati
Yakajairika DTVV
Kupinza tembiricha yemhepo sensor ndeimwe yeakawanda masisitimu uye masensa mumotokari. kuparara mukushanda kwayo kunogona kukanganisa zvakananga kushanda kwejini inopisa mukati, kunyanya munguva inotonhora.
Chii chinonzi intake air sensor uye iripi
Intake air tembiricha sensor (yakapfupikiswa DTVV, kana IAT muChirungu) inodiwa kugadzirisa kuumbwa kwemafuta musanganiswainopiwa kune injini inopisa yemukati. Izvi zvinodikanwa kune yakajairika kushanda kwemota mumamiriro akasiyana ekushisa. Saizvozvo, kukanganisa mune yekudyara tembiricha yemhepo sensor kune yakawanda inotyisidzira nekunyanyisa kushandiswa kwemafuta kana kusagadzikana kushanda kweinjini yekupisa kwemukati.
DTVV iri pamhepo sefa imba kana kuseri kwayo. Izvo zvinoenderana nekugadzirwa kwemotokari. Iye zvakaitwa zvakasiyana kana inogona kunge iri chikamu cheiyo mass air flow sensor (DMRV).
Ndeipi sensor yekushisa kwemhepo yekupinda?
kutora mhepo tembiricha sensor kutadza
Pane akati wandei zviratidzo zvekutadza kushanda kwemhepo tembiricha sensor. Pakati pavo:
- kukanganisika mukushanda kweinjini yekupisa kwemukati pasina basa (kunyanya mumwaka unotonhora);
- yakakwira zvakanyanya kana yakaderera isingaite kumhanya kweiyo mukati memoto injini;
- matambudziko nekutanga mukati memoto injini (mune chando chakanyanya);
- kuderedzwa kwesimba reICE;
- kupisa kwemafuta.
Kuparara kunogona kuitika nekuda kwezvikonzero zvinotevera:
- mechanical kukanganisa kune sensor inokonzerwa nezvikamu zvakasimba;
- kurasikirwa kwekunzwa nekuda kwekusvibiswa (kuwedzera mune inertia yenguva pfupi);
- kusakwana kwemagetsi mumagetsi emotokari kana kuti magetsi asina kunaka;
- kukundikana kwechiratidzo wiring ye sensor kana kushanda kwayo kusina kururama;
- pfupi pfupi mukati meIAT;
- kusvibiswa kwema sensor contacts.
Kuongorora uye kuchenesa DTVV.
Kutarisa iyo inopinza yemhepo tembiricha sensor
Usati watarisa kupinza kwemhepo tembiricha sensor, unofanirwa kunzwisisa iyo nheyo yekushanda kwayo. Iyo sensor inobva pane thermistor. Zvichienderana nekupisa kwemhepo inouya, DTVV inoshandura kupikisa kwayo magetsi. Zviratidzo zvinogadzirwa munyaya iyi zvinotumirwa kuECM kuitira kuti uwane chiyero chakanaka chemafuta.
Kuongororwa kweiyo inopinza tembiricha yemhepo sensor inofanirwa kuitwa pahwaro hwekuyera kushorwa uye hukuru hwemagetsi masaini anobva mairi.
Muedzo unotanga nekuverenga kwekupikisa. Kuti uite izvi, shandisa ohmmeter nekubvisa sensor kubva mumotokari.Maitirwo acho anoitika nekubvisa waya mbiri uye kudzibatanidza kune yekuyeresa mudziyo (multimeter). Kuyera kunoitwa mune maviri modes ekushanda kweinjini yekupisa yemukati — “kutonhora” uye nekumhanya kuzere.
Supply voltage kuyerwa
Sensor resistance measure
Muchiitiko chekutanga, kushorwa kuchave kwakanyanya-kupokana (anoverengeka kOhm). Muchipiri - kuderera-kupikisa (kusvika kune imwe kOhm). Mirayiridzo yekushanda ye sensor inofanira kuva netafura kana girafu ine maitiro ekupikisa zvichienderana nekushisa. Kutsauka kwakakosha kunoratidza kushanda kwakashata kwechigadzirwa.
Semuenzaniso, tinopa tafura yechiyero chekushisa uye kuramba kwemhepo inobata sensor mukati memoto weVAZ 2170 Lada Priora:

Padanho rinotevera, tarisa kubatana kwevanotungamira kune mudziyo wekudzora. Kureva, uchishandisa tester, ita shuwa kuti pane conductivity yekusangana kwega kwega pasi. Shandisa ohmmeter, iyo yakabatana pakati peiyo tembiricha sensor yekubatanidza uye yakadzimwa kudzora mudziyo wekubatanidza. Muchiitiko ichi, kukosha kunofanira kuva 0 ohm (ona kuti unoda pinout yeizvi). Tarisa chero kubata pane sensor yekubatanidza ine ohmmeter ine chinongedzo chakadimburirwa pasi.
DTVV kuramba kuyerwa kweToyota Camry XV20
Semuenzaniso, kuti utarise kupikisa kwe sensor paToyota Camry XV20 motokari ine 6-cylinder injini, unoda kubatanidza ohmmeter (multimeter) kune 4th uye 5th sensor outputs (ona mufananidzo).
Zvisinei, kazhinji DTVV ine zvinyorwa zviviri zve thermistor, pakati pazvo zvakakosha kutarisa kupikisa kwechinhu. isu tinokuunzira zvakare iyo IAT yekubatanidza dhizaini mumotokari yeHyundai Matrix:
Kubatanidza dhayagiramu yeDTVV ine DBP yeHyundai Matrix
Nhanho yekupedzisira yekusimbisa ndeye tsvaga voltage pane connector. Muchiitiko ichi, iwe unofanirwa kubatidza moto wemoto. Kukosha kwechiratidzo chemagetsi kunofanira kuva 5 V (kune mamwe maDTVV emhando, kukosha uku kunogona kusiyana, tarisa mu data yepasipoti).
Iyo inopinza yemhepo tembiricha sensor ndeye semiconductor mudziyo. Somugumisiro, haigoni kugadzirwa. Zvinongogoneka chete kuchenesa vanobatika, tarisa waya dzechiratidzo, pamwe nekutsiva zvachose mudziyo.
Kutora mhepo tembiricha sensor kugadzirisa
Ndingagadzirisa sei tembiricha sensor BB.
Kunyanya iyo yakapusa mhando yeIAT kugadzirisa - kuchenesa. Kuti uite izvi, iwe uchada imwe mhando yekuchenesa mvura (carb cleaner, doro, kana imwe yekuchenesa). Zvisinei, yeuka kuti unofanira kushanda nokungwarira, kuti usakuvadza vanhu vekunze.
Kana iwe ukasangana nedambudziko apo sensor inoratidza tembiricha isiriyo, panzvimbo yekutsiva yakakwana, unogona kuigadzirisa. Nokuda kweizvi tenga thermistor ine maitiro akafanana kana akafananaiyo ine thermistor yakatoiswa pamotokari.
Icho chakakosha chekugadzirisa ndechekutengesa uye kuvatsiva mudzimba dze sensor. Kuti uite izvi, iwe uchada simbi yesimbi uye hunyanzvi hwakakodzera. Kubatsira kwekugadzirisa uku ndiko kuchengetedza mari kwakakosha, sezvo thermistor inodhura dhora kana zvishoma.
Kutsiva iyo inopinza tembiricha yemhepo sensor
Iyo yekutsiva nzira haina kuoma uye haitore nguva yakawanda. Iyo sensor inosungirirwa pa 1-4 mabhoti anoda kuvharwa, pamwe chete nekufamba kuri nyore kubvisa simba rekubatanidza kuitira kuti abvise iyo inopinza mhepo sensor kubva panzvimbo yayo.
Paunenge uchitenga sensor nyowani, ita shuwa kuti yakakodzera mota yako. Mutengo wayo unotangira pamadhora makumi matatu kusvika pamadhora makumi matanhatu, zvichienderana nerudzi rwemota nemugadziri.
