Misa mweya inoyerera sensor

DMRV kana maf sensor - chii ichocho? Iro zita rakakodzera re sensor iMass Airflow sensor, isu tinowanzoidaidza kuti inoyerera mita. Basa rayo nderekuyera huwandu hwemhepo inopinda muinjini pachikamu chenguva.

Ainoita

Iyo sensor ndeye platinamu shinda (uye saka haina kudhura), iyo iyo magetsi inopfuudzwa, ichidziya iwo. Imwe shinda itambo yekudzora, mhepo inopfuura nepachipiri, ichitonhodza. Iyo sensor inogadzira chiratidzo che-frequency-pulse, iyo frequency yaro yakanangana nehuwandu hwemhepo inopfuura nemu sensor. Iyo controller inonyoresa shanduko mune yazvino inopfuura neyechipiri, yakatonhorera filament uye inoverengera huwandu hwemhepo inopinda mumotokari. Zvichienderana nehuwandu hwezviratidzo, mutongi anogadzirisa nguva yemafuta injectors nekugadzirisa kuenzana kwemhepo nemafuta mumafuta emafuta. Iko kuverengerwa kweiyo mass air flow flow sensor ndiyo huru parameter iyo iyo controller inoisa iyo kushandiswa kwemafuta uye yekudzima nguva. Kushanda kwemamita ekuyerera kunokanganisa kwete chete kudyiwa kwemafuta, kunaka kwemusanganiswa, simba rejini, asiwo, zvisina kunanga, injini yekushandisa.

Chii chinoitika kana ukadzima MAF?

Ngatitangei nenyaya yekuti kana mita yekuyerera ichidzimwa, injini inopinda mune emergency operation mode. Izvi zvingatungamirira kuchii? Zvichienderana nemuenzaniso wemotokari uye, maererano, iyo firmware - kumisa injini (sepaToyota) kuwedzera kushandiswa kwemafuta kana ... pasina. Tichifunga nezvakawanda mameseji kubva kumaforamu emotokari, vanoedza vanocherekedzawo kuwedzera agility mushure mekuvhara uye kusavapo kwekutadza mukushanda kwemota. Hapana akanyatsoita kuyerwa kwekuchinja kwemafuta uye hupenyu hweinjini. Kana zvakakodzera kuedza manipulations akadaro pamotokari yako zviri kumuridzi wekusarudza.

Kukanganisa zviratidzo

Zvisina kunanga, kusashanda kweDMRV kunogona kutongwa nezviratidzo zvinotevera:

• Mwenje weCHEK ENGINE unovheneka;
• Motokari inomhanya zvishoma nezvishoma (benzi);
• Kusagadzikana kushanda kweinjini pakusina basa;
• Injini haina kutanga "inopisa";
• Kuwedzera kwekushandisa kwemafuta;
• Injini inomira kana uchichinja magiya.

Yakasviba DMRV (parutivi maonero)

Zviratidzo zvinotsanangurwa pamusoro apa zvinogona kukonzerwa nezvimwe zvikonzero, saka zviri nani kuita cheki chaiyo yekuyerera kwemhepo sensor pachiteshi chebasa uchishandisa hunyanzvi. Kana pasina nguva, iwe hausi kuda, kana iwe unonzwa tsitsi nemari, unogona kutarisa kushanda kweDMRV iwe pachako nepamusoro, asi kwete 100% chokwadi.

Diagnostics yehuwandu hwekuyerera kwemhepo sensor

Zvinetso zvekuzviongorora kweiyo flowmeter inokonzerwa nekuti ichi chinhu chinokanganisa. Kutora kuverenga pahuwandu hwekuchinja kunoratidzwa mubhuku kazhinji hakupi mhedzisiro. Iko kuverenga kwakajairwa, asi sensor haina kunaka. Heano nzira shoma dzekuongorora hutano hwe sensor:

1. Nzira iri nyore ndeyekutsiva iyo DMRV neimwe yakafanana uye kuongorora mhedzisiro.
2. Tarisa pasina kutsiva. Bvisa flowmeter. Bvisa iyo sensor yekubatanidza uye tanga injini. Kana iyo DMVR yakadzimwa, controller inoshanda mune emergency mode. Kuwanda kwemafuta emusanganiswa kunotsanangurwa chete nechinzvimbo che throttle. Muchiitiko ichi, injini inochengetedza kumhanya pamusoro pe1500 rpm. Kana motokari ikava "nekukurumidza" pamuedzo wekuedza, saka kazhinji kacho sensor inokanganisa
3. Kuongororwa kwekuona kweMAF. Bvisa corrugated air intake chubhu. Kutanga, nyatsoongorora corrugation. Iyo sensor inogona kunge iri mumamiriro ezvinhu akanaka, uye chikonzero chekushanda kwayo kusina kugadzikana kutsemuka muhose yakasvibiswa. Kana nzvimbo yacho isina kusimba, ramba uchiongorora. Izvo zvinhu (shinda dzeplatinamu) uye mukati meiyo corrugation inofanira kunge yakaoma, isina mavara emafuta uye tsvina. Chinonyanya kukonzera kukanganisa kusvibiswa kwezvinhu zveflowmeter..
4. Kutarisa iyo MAF ine multimeter. Nzira yacho inoshanda kuBosh DMRV nenhamba dzekabhuku 0 280 218 004, 0 280 218 037, 0 280 218 116. Tinoshandura tester kuyera zvakananga voltage, nechiyero chekuyera che2 Volts.

DMRV kuonana dhayagiramu:

DMRV kuonana dhayagiramu

Nzvimbo kubva padhuze kusvika kumhepo yakarongeka 1. sensor signal input 2. DMRV supply voltage output 3. grounding (pasi). 4. yakabuda kune huru relay. Muvara wewaya unogona kusiyana, asi kurongeka kwepini kunogara kwakafanana. Tinobatidza moto pasina kutanga injini. Isu tinobatanidza dzvuku probe ye multimeter kuburikidza nezvisimbiso zverubha zvekubatanidza kune yekutanga kusangana (kazhinji waya yero), uye dema probe kune yechitatu kusvika pasi (kazhinji waya yakasvibirira). Isu tinotarisa kuverenga kweiyo multimeter. Sensor nyowani inowanzoverenga pakati pe0.996 uye 1.01 volts. Nokufamba kwenguva, kushungurudzika kunowanzowedzera. Kukosha kwakakura kunoenderana nekuwedzera sensor kupfeka. 1.01 ... 1.02 - sensor iri kushanda. 1.02 ... 1.03 - mamiriro acho haasi akanakisisa, asi kushanda 1.03 ... 1.04 - pfuma iri pamagumo. 1.04 ... 1.05 - kurwadziwa 1.05 ... uye zvimwe - zvechokwadi, inguva yekuchinja.

Nzira dzose dziri pamusoro apa dzekuongororwa kwemusha hazvipi 100% vimbiso yekuvimbika kwechigumisiro. Kuongororwa kwakavimbika kunogona kuitwa chete pamichina yakakosha.

Ita-iwe-iwe pachako kudzivirira uye kugadzirisa kweDMRV

Kutsiviwa nenguva kwesefa yemhepo uye kutarisa mamiriro episton mhete uye zvisimbiso zvinokubvumira kuti uwedzere hupenyu hweDMRV. Kupfeka kwavo kunokonzeresa kuwanda kwemagasi ecrankcase nemafuta. Iyo firimu yemafuta, inowira pazvinhu zvinonzwisisika zve sensor, inoiuraya. Pane imwe sensor ichiri mhenyu, kuverenga kunoyerera kunogona kudzorerwa nepurogiramu ye "MARV corrector." Nekubatsira kwayo, unogona kukurumidza kuchinja kuenzaniswa kweMARV mu firmware. Iyo purogiramu iri nyore kuwana uye kurodha pasina matambudziko paInternet. Kuti ubatsire kumutsiridza isingashande sensor, luftmassensensor reiniger cleaner inogona kubatsira. Nokuda kweizvi, unoda:

• Bvisa sensor kubva mujini sezvatsanangurwa pamusoro apa.
• Pfaya gadziriro yacho nokungwarira uye nerupo pane chinhu chinonzwa.
• Mirira kusvikira zvinosvibisa zvakasara zvapera.
• Pukuta sensor zvakanaka usati waisa. Nekudzivirira, nzira yacho inogona kudzokororwa isati yatsiviwa yega yega sefa yemhepo.

Kana kucheneswa kukatadza, iyo sensor isina kukwana inofanira kutsiviwa. Mutengo weiyo mass air flow sensor unobva ku2000 rubles, uye kune ekunze mhando inowanzokwira zvakanyanya, semuenzaniso, mutengo weToyota 22204-22010 sensor inenge 3000 rubles. Kana iyo sensor inodhura, usakurumidza kutenga imwe itsva. Kazhinji, zvigadzirwa zvekumaka zvakafanana zvinoiswa pamhando dzakasiyana dzemotokari, uye mutengo sezvisara zvakasiyana. Nyaya iyi inowanzoonekwa neBosh DMRV. Iyo kambani inopa masensa akafanana eVAZ uye kune akawanda emhando dzekunze. Izvo zvinodikanwa kuparadzanisa sensor, nyora pasi kucherechedzwa kwechinhu chinonyanya kuoma, zvinogoneka kuti inogona kutsiviwa neVAZ imwe.

DBP pachinzvimbo cheDMRV

Mumotokari dzinotengeswa kunze kwenyika, kubva kuma2000, pachinzvimbo chemita yekuyerera, gauge yekumanikidza (DBP) yakaiswa. Zvakanakira zveDBP zvinomhanya zvakanyanya, kuvimbika uye kusazvibata. Asi kuisa panzvimbo yeDMRV inyaya kune avo vanofarira tuning pane vatyairiwo zvavo.
