Sensa ya Throttle valve VAZ 2107

Poyamba, zitsanzo za Vaz-2107 zinapangidwa ndi carburetors, ndipo kumayambiriro kwa zaka za m'ma 2000, magalimoto anayamba kukhala ndi zida zogwiritsira ntchito magetsi (ECU). Izi zinafunika kuyika zina zowonjezera zida zoyezera pazinthu zosiyanasiyana, kuphatikizapo throttle position sensor (TPDZ) ya jekeseni ya VAZ-2107).

Galimoto ya VAZ 2107:

Kodi a DPS amachita chiyani?

Ntchito ya valve throttle ndikuwongolera kuchuluka kwa mpweya womwe umalowa mu njanji yamafuta. Pamene "gasi" pedal ikakanikizidwa, kusiyana kwakukulu kwa valve yodutsa (accelerator), ndipo, motero, mafuta mu majekeseni amawonjezeredwa ndi mpweya ndi mphamvu yaikulu.

TPS imakonza malo a accelerator pedal, omwe "adanenedwa" ndi ECU. Woyang'anira chipika, pomwe kusiyana kwapakati kumatsegulidwa ndi 75%, kumasinthira injini kuyeretsa kwathunthu. Vavu yotsekemera ikatsekedwa, ECU imayika injiniyo mopanda pake - mpweya wowonjezera umalowetsedwa kudzera mu valavu ya throttle. Komanso, kuchuluka kwa mafuta omwe amalowa m'zipinda zoyaka moto za injini zimadalira sensor. The ntchito zonse injini zimadalira serviceability wa kagawo kakang'ono.

chipangizo

Throttle udindo zipangizo VAZ-2107 ndi mitundu iwiri. Awa ndi masensa a kukhudzana (resissive) ndi mtundu wosalumikizana. Mtundu woyamba wa chipangizo ndi pafupifupi makina voltmeter. The coaxial kugwirizana ndi chipata rotary amaonetsetsa kayendedwe ka contactor pamodzi njanji metallized. Kuchokera pakusintha kozungulira kwa shaft, mawonekedwe apano akudutsa pa chipangizocho motsatira chingwe kuchokera pamagetsi owongolera (ECU) a injini amasintha).

Resistive sensor circuit:

Mu mtundu wachiwiri wa mapangidwe osalumikizana, maginito okhazikika a ellipsoidal amakhala pafupi kwambiri ndi kutsogolo kwa shaft yonyowa. Kuzungulira kwake kumayambitsa kusintha kwa maginito amagetsi a chipangizo chomwe dera lophatikizika limayankha (mphamvu ya Hall). Mbale yomangidwa nthawi yomweyo imayika mbali yozungulira ya throttle shaft, monga idanenedwera ndi ECU. Zipangizo zamaginito ndizokwera mtengo kwambiri kuposa zida zamakina, koma zodalirika komanso zolimba.

TPS Integrated circuit:

Chipangizocho chimatsekeredwa mubokosi lapulasitiki. Mabowo awiri amapangidwa pakhomo lomangirira ndi zomangira. Kutuluka kwa cylindrical kuchokera ku thupi la throttle kumalowa muzitsulo za chipangizocho. Cholumikizira chingwe cha ECU chili mu cholumikizira chakumbali.

malfunctions

Zizindikiro za kulephera kugwira ntchito zingadziwonetsere m'njira zosiyanasiyana, koma makamaka zimakhudza kuyankha kwa injini.

Zizindikiro za kusagwira ntchito kwa TPS, zomwe zikuwonetsa kuwonongeka kwake:

• zovuta kuyambitsa injini yozizira;
• kusakhazikika kwa injini mpaka kuyimitsidwa kwathunthu;
• kukakamiza "gasi" kumayambitsa kuwonongeka kwa injini, ndikutsatiridwa ndi kuwonjezeka kwakukulu kwa liwiro;
• idling imatsagana ndi kuchuluka kwa liwiro;
• mafuta akuwonjezeka mopanda nzeru;
• kutentha kwa kutentha kumakonda kupita kumalo ofiira;
• nthawi ndi nthawi mawu akuti "Check Engine" amawonekera pa dashboard.

Njira yolumikizirana yowonongeka ya sensor resistive:

diagnostics

Zizindikiro zonse zomwe zili pamwambazi za kusagwira ntchito kwa throttle position sensor zingagwirizane ndi kulephera kwa masensa ena pakompyuta. Kuti mudziwe molondola kuwonongeka kwa TPS, muyenera kudziwa.

Chitani izi:

1. Chotsani chivundikirocho ku chipika cholumikizira sensor.
2. Kuyatsa ndi kuyatsa koma injini sinayambike.
3. Lever ya multimeter ili pamalo ohmmeter.
4. Ma probe amayesa voteji pakati pa olumikizana kwambiri (waya wapakati amatumiza chizindikiro ku kompyuta). Mphamvu yamagetsi iyenera kukhala pafupifupi 0,7V.
5. The accelerator pedal imapanikizidwa mpaka pansi ndipo multimeter imachotsedwanso. Panthawiyi magetsi ayenera kukhala 4V.

Ngati ma multimeter akuwonetsa zinthu zosiyanasiyana ndipo samayankha konse, ndiye kuti TPS ili kunja kwa dongosolo ndipo iyenera kusinthidwa.

Kusintha kwa DPDZ

Tiyenera kuzindikira nthawi yomweyo kuti kukonzanso kwa gawo linalake kungangokhudza zowonongeka (makina) masensa, popeza zipangizo zamagetsi sizingathe kukonzedwa. Kubwezeretsanso nyimbo yomwe yawonongeka kunyumba ndizovuta ndipo mwachiwonekere sizothandiza. Chifukwa chake, zikakanika, njira yabwino kwambiri ingakhale m'malo mwake ndi TPS yatsopano.

Sikovuta kusinthira chipangizo chowonongeka ndi sensa yatsopano yothamangitsira. Zokumana nazo zochepa ndi screwdriver ndi zolumikizira zida zimafunikira.

Izi zimachitika motere:

• galimotoyo anaika pa malo lathyathyathya, kukweza handbrake lever;
• chotsani chodutsa choyipa cha batri;
• chotsani chipika chamawaya papulagi ya TPS;
• pukutani mfundo zokwezera sensa ndi chiguduli;
• masulani zomangira ndi screwdriver ya Phillips ndikuchotsa kauntala;
• khazikitsani chipangizo chatsopano, limbitsani zomangira ndikuyika chipika mu cholumikizira cha sensor.

Akatswiri amalangiza kugula throttle position sensor yokha kuchokera kwa opanga odziwika. Pofuna kusunga ndalama, madalaivala amakhala mikhole ya ogulitsa zinthu zabodza zotsika mtengo. Pochita izi, amakhala pachiwopsezo chongokakamira mwadzidzidzi pamsewu kapena "kugwedezeka" mozungulira msewu waukulu, ndikuwononga mafuta ochulukirapo kupita kumalo opangira mafuta apafupi.
