Mhepo inoyerera sensor (MAF), inozivikanwawo semhepo yekuyerera mita, ndeimwe yeakakosha ma sensors eEFI injini.Inoshandura kuyerera kwemhepo kunopinda muchiratidzo chemagetsi uye inotumira kune yemagetsi control unit (ECU).Seimwe yemasaini ekutanga ekuona jekiseni remafuta, inzwa inoyera kuyerera kwemhepo ichipinda muinjini.YASEN inotungamira MAF sensor china mugadziri.
Iyo yekuyerera kwemhepo sensor (MAF) inoiswa pakati pemhepo sefa uye yakawanda yekutora kuyera mhando yemhepo inopinda mujini.Iyo ECM inoverengera iyo mafuta jekiseni pulse hupamhi uye yakakosha yekubatidza kumberi angle zvichienderana neiyo MAF chiratidzo.
Kupisa-waya kuyerera kwemhepo (MAF)
Iyo inopisa waya yakawanda yemhepo inoyerera (MAF) sensor circuit inoumbwa ne sensor, control module uye waya inobatanidza zvimwe zvikamu zviviri.Iyo sensor inoburitsa iyo DC voltage simba rebhangi chiratidzo kune iyo simba rekudzora module (ECM), iyo amplitude inoenderana nehuwandu hwemhepo yeinjini.
Chimiro cheiyo inopisa waya yekuyerera kwemhepo sensor ine platinamu inopisa waya (yemagetsi kupisa waya) inonzwa kuyerera kwemhepo, tembiricha yekutsiva tembiricha (waya inotonhora) inogadziriswa zvinoenderana nekupisa kwemhepo yekupinda, control circuit board isina waya charger. iyo inodzora ikozvino yewaya inopisa uye inoburitsa chiratidzo chekubuda, uye goko remhepo inoyerera sensor uye zvimwe zvikamu.
Mushure mekubatidza iyo ignition motion sensor switch, iyo platinamu inopisa waya inopihwa simba uye inogadzira kupisa.Apo mhepo inofamba netambo iyi, kutonhora kwetambo inopisa kunoenderana nehuwandu hwemhepo inopinza.ECM inochengetedza kutonhora kwewaya inopisa nguva dzose nekudzora ikozvino inoyerera kuburikidza newaya inopisa, kuitira kuti ikozvino ienderane nehuwandu hwemhepo inopinza, nepo ECM inogona kuyera huwandu huripo hwehuwandu hwemhepo kuburikidza nekuona ikozvino ine simba.
Hunhu hwemhepo inoyerera inonzwa hukuru hudiki, huremu huremu, intuitive uye yakajeka kuratidza kuverenga, kuvimbika kwepamusoro, kusakanganiswa nekunze kwesimba rekupa, uye anti-mheni.
Kukanganisa chiitiko uye kuongororwa kwemhepo inoyerera sensor
Iko kukanganisa kwemhepo inoyerera (MAF) sensor yakakamurwa kuita mapoka maviri.Imwe ndeyokuti chiratidzo chinodarika chiyero chakatarwa, zvichiratidza kuti mhepo inoyerera sensor yakundikana.Mota dzemazuva ano dzemagetsi dzinodzorwa dzine kutadza kudzivirira basa.Kana chiratidzo che sensor chikatadza, iyo yemagetsi control unit (ECU) ichaitsiva neiyo yakatarwa kukosha, kana kutsiva chiratidzo cheyakashata sensor nechiratidzo chemamwe ma sensor.Mushure mekunge iyo MAF sensor yakundikana, ECU inoitsiva nechiratidzo che throttle position sensor.Rimwe dambudziko ichiratidzo chisina kujeka (kureva kuita dhift).Kusarurama kuyerera kwemhepo sensor chiratidzo kunogona kukuvadza zvakanyanya senge salmosan azamethiphos pane kusaina chiratidzo.Sezvo chiratidzo chisingapfuuri chiyero chakatarwa, iyo yemagetsi control unit (ECU) ichadzora huwandu hwejekiseni yemafuta maererano neiyi isina kurongeka yekuyerera kwemhepo chiratidzo, nekudaro, musanganiswa uchave wakatetepa kana wakapfuma.Kana pasina chiratidzo chekuyerera kwemhepo, ECU ichashandisa chiratidzo che throttle position sensor panzvimbo, uye kukurumidza kusina basa kwejini kwakagadzikana.
Kana iyo mhepo inoyerera inonzwa chiratidzo inokundikana, iyo huru yekukundikana zviitiko zvinonetsa kutanga, kutadza kunonoka, kukurumidza kukurumidza, kutadza kushandiswa kwemafuta uye kupera kwekuita (EGR), etc. Semuenzaniso, motokari yeMAF sensor connector haina kuiswa zvakanaka, se mhedzisiro, iyo sensor inosunungurwa mushure mekunge mota yatanga.Neiyi nzira, iyo voltage chiratidzo kukosha yakaonekwa neMAF sensor inokurumidza kushanduka portafilter (yakakwirira uye yakaderera shanduko).Iyo ECM inodzora jekiseni remafuta pulse hupamhi zvichienderana nechiratidzo ichi, izvo zvinoita kuti injini isagadzikane kumhanya.
Zvikonzero zvikuru zvekutadza kweMAF:
- Kukuvadza kwemukati kune sensor;
- Yakashata yekuisa nzira ye sensor (reverse)
- Vhura / pfupi dunhu re sensor terminal kana mutsara
Kurapa kweyakakuvadzwa inopisa firimu kuyerera kwemhepo (MAF) sensor
Kana magetsi emagetsi akanyanya kukwira kana paine pakarepo high voltage, inopisa firimu air flow sensor iri nyore kupisa.Chikonzero nei iyo peak voltage yedunhu yakanyanyisa kukwirira (kupfuura 16V) kazhinji kuti bhatiri rakanyanya vulcanized, izvo zvinoderedza kugona kwayo uye hazvigone kutora peak voltage yejenareta.Naizvozvo, bhatiri vulcanization chimwe chezvikonzero zvekukuvadzwa kweiyo inopisa firimu air flow sensor.Mhinduro ndeyekuisa "7812" matatu terminal voltage inodzikamisa yakabatanidzwa dunhu kumberi kweiyo inopisa firimu kuyerera kwemhepo sensor.
Mhedziso
MAF sensor chikamu chakakosha chemotokari, zvinodikanwa kuti vanhu vave nekunzwisisa kupfupi kune maitiro ekuongorora nekugadzirisa kukuvara kwayo.Chaizvoizvo kune akawanda China wholesale sensor supplier, kuti uwane rumwe ruzivo, pls bata YASEN.
