Kodi odometer ndi chiyani?

Kodi zitenga nthawi yayitali bwanji? Funso ili nthawi zambiri limachokera kwa dalaivala pomwe amayendetsa pagalimoto yachilendo. Poterepa, ndizovuta kudziwa nthawi yeniyeni yoyendetsera galimoto - sizikudziwika kuti mseu ndi wotani, komanso ngati pali zochuluka pamsewu. Koma mtunda wotsalira ukhoza kutsimikizika.

Pachifukwa ichi, odometer imayikidwa m'galimoto. Kodi chipangizochi ndi chiyani? Kodi amawerengera bwanji mtunda womwe wayenda ndipo chiopsezo chake chimawonongeka? Tiyeni tikambirane mafunso amenewa ndi ena mwadongosolo.

Kodi odometer ndi chiyani?

Odometer ndi cholembera chomwe chimayeza mtunda womwe galimoto yapita. Imaikidwa pa dashboard m'chigawo cha othamanga (zenera pamlingo wake kuti zizindikire bwino). Chida chomwe chili pagululi chikuwoneka ngati zenera lokhala ndi manambala.

Mu mtundu wakale, chipangizochi chili ndi mizere iwiri yokhala ndi manambala. Chimodzi chikuwonetsa kutalika kwa galimotoyo kuyambira pomwe mita idayika. Mzere wachiwiri umatchedwa counter mileage ya tsiku ndi tsiku. Ikuwonetsa makilomita omwe amayenda ndi galimotoyo kuyambira pomwe kuyika kunayikidwa ku 0 (pali batani lolingana ndi izi).

Kodi odometer ndi chiyani?

Kuphatikiza pa kuti odometer imathandizira driver kuti ajambule mtunda woyenda, chipangizocho chimaperekanso thandizo lothandiza pogula galimoto kumsika wachiwiri. Ma mileage omwe akuwonetsedwa pamzere waukulu wa odometer angakuuzeni ngati kuli koyenera kutenga galimoto yatsopano pamtengo wotsika. Kuphatikiza uku kumadzutsa kukayikira nthawi yomweyo.

Kugwira ntchito kwa chipangizocho

Nayi ntchito zingapo zotsutsa:

• Woyendetsa amatha kugwiritsa ntchito mileage kuti adziwe nthawi yomwe galimotoyo ikufunika kukonza. Nthawi yomweyo, ndikofunikira kukonza zizindikiro ndikuzilemba penapake kuti musaiwale;
• M'magalimoto, gawo loyang'anira lomwe silikusonyeza kuchuluka kwa mafuta omwe alipo komanso zomwe zikuchitika masiku ano, odometer ikuthandizira kudziwa "kususuka" kwagalimoto;
• Ngati sensa yamafuta ikasokonekera, ikatha kuthira mafuta mokwanira, kauntala wa tsiku ndi tsiku amakhala zero. Mafuta mu thanki (kapena gasi mu silinda) atatha, kugwiritsiridwa ntchito kwenikweni kumawerengedwa;
• Ikuthandizani kudziwa kuchuluka kwatsala kuti muyendetse komwe mukupita, ngati mukudziwa mtunda weniweni kuchokera pa "A" mpaka pa "B".

Kubwezeretsanso kauntala kumatheka kokha pa mileage ya tsiku ndi tsiku, ndipo chisonyezo chachikulu sichinakhazikitsidwenso ku zero. Ntchitoyi ndi yothandiza pakakhala kusamvana pakati pa wogwira ntchito ndi wolemba ntchito pankhani yokhudza kampani kapena galimoto.

Wopanga sanapereke mwachindunji kukonzanso kwa mileage, kotero kuti dalaivala sanachite mwangozi kapena kuti abise zofunikira kuchokera kwa anthu omwe ali ndi ufulu wodziwa izi.

Mfundo ya Odometer

Odometer idapangidwa m'njira yoti kilomita iliyonse yomwe idayendetsedwa ndi galimotoyo imagwirizana ndi kuchuluka kwamitundu yamagudumu. Komanso, izi sizikusintha. Chokhacho ndi pamene woyendetsa galimoto amaika mawilo osayenerera pagalimoto yake. Poterepa, odometer iwonetsanso mtunda winawake, koma chipangizocho chidzakhala ndi vuto lalikulu.

Izi ziyenera kukumbukiridwa, popeza gululi liziwonetsa milingo yolakwika - mwina pang'ono kapena pang'ono. Zimatengera ngati kukonza kumachitika nthawi yake.

Chipangizocho chimaphatikizapo zinthu zotsatirazi:

• Chojambulira chama Wheel - Chidayikidwa pafupi ndi limodzi lamagudumu akutsogolo. Pali zosintha ndi sensa mu gudumu lokha, komanso pali mitundu ya ma odometer omwe ali ndi sensa yomwe imayikidwa mu gearbox. Mulimonsemo, kuyeza kudzachitika malinga ndi gawo lanji la galimotoyi;
• Odometer drive - amawerenga ma liwiro ndipo, kutengera mtundu wa chipangizocho, amasamutsira chizindikiro ichi ku ECU, kapena molumikizana ndi magiya. M'magetsi ambiri amagetsi, njira zotere sizingagwiritsidwe ntchito, ndipo chizindikiritso chochokera ku sensa kudzera pamawaya chimatumizidwa nthawi yomweyo ku gawo lowongolera;
• Screen - pamitundu yamagetsi, imawonetsa chizindikirocho chowerengedwa ndi unit control (ma algorithm amaikidwa ndi wopanga kapena pulogalamuyo pambuyo pa firmware) kutengera kusintha kwa gudumu loyendetsa.

Kuwerenga molondola

Odometer iliyonse, ngakhale magudumu wamba agwiritsidwa ntchito, ili ndi vuto. Izi ndizololedwa chifukwa mita siyofunika mtunda wamagalimoto ngati kilomita.

Ndipo kukonza kwa galimoto nthawi zambiri kumachitika kudzera pamakilomita zikwi zingapo. Pachifukwa ichi, kulakwitsa kwa njira (ngakhale analogue yamagetsi) kumatha kuyambira magawo awiri mpaka khumi. Komanso, chipangizocho chimalemba kuchuluka kwa makilomita, osati masentimita kapena mita.

Kuphatikiza pa zolakwika za fakitore mgalimoto yokhala ndi ma mileage apamwamba, chipangizocho chimatha kuwerengera molondola kwambiri. Izi ndichifukwa chovala mbali kapena kulephera kwa sensa.

Kuwongolera kwa odometer

Popeza pali zinthu zambiri zomwe zimakhudza kuwerenga kwa ma odometer, chipangizochi sichingatchulidwe kuti ndi cholondola. Koma ngakhale ndi zolakwika zochepa, ngati galimoto imayendetsa maulendo ataliatali tsiku lililonse (mwachitsanzo, mwini wake ndi woyendetsa taxi), ndiye kuti odometer idzakhalabe ndi chithunzi chosangalatsa.

Sizingatheke kuti mugulitse galimoto yotere pamsika wachiwiri, ngakhale galimotoyo itagulidwa mchipinda chowonetsera posachedwa. Kuti mwiniwake wa galimoto yoteroyo athe kuigulitsa pamtengo wokwera, ena amapita kukasinthanso kauntala wa mileage. Kuti mumve zambiri zamomwe mungazindikire kuti izi zasinthidwa, werengani mu ndemanga yapadera. A apa onani kafukufuku waposachedwa pa galimoto yomwe ingakhale yopindika kwambiri.

Tsoka ilo, pali ogulitsa ambiri omwe akuchita nawo ma mileage omwe kusinthitsa kwa ma odometer asanagulitsidwe kwakhala mwambo. Ngati tizingolankhula zamakina opanga mamitala, ndiye kuti zomwe zikuchitika pamilanduyo kapena zomata zisonyeza kusintha kwa mileage. Ponena za ma odometer amagetsi, ndizosatheka kuwonetsa kusintha koteroko. Kuti muwunikenso, mufunika zida zapadera zomwe zimayang'ana kusiyana pakati pa zolakwika ndi kuwerenga kwa odometer (gulu loyang'anira limalemba mileage pomwe cholakwika ichi chinawonekera).

Mitundu yazida

Pali zinthu zitatu zazikuluzikulu pazida za odometer:

• Gulu lomwe ma mileage oyenda amawonetsedwa;
• Makina omwe amawerenga kusintha kwa galimoto yolumikizidwa ndi mawilo;
• Wowongolera yemwe amasintha kuchuluka kwakusintha kwa shaft yoyendetsa kukhala chizindikiritso cha ma kilomita omwe adayenda.

Makinawa amatha kukhala ndi makina odula zamagetsi, zamagetsi kapena zamagetsi. Tiyeni tione kusiyana pakati pawo.

Mawotchi odometer

Kusinthaku kumayang'ana mtunda woyenda mwamakaniko. Kapangidwe ka mita yotereyi imakhala ndi chingwe choyendetsa chomwe chimayikidwa mukachitsulo kansalu koluka kamene kamateteza kukhudzana ndi chitsulo ndi mpweya wouma, womwe ungachite dzimbiri msanga.

Kusinthidwa kwa ma odometers kulumikizidwa ndi bokosi lamagetsi (shaft yotulutsa), komano, ku counter ya makina. Pafupifupi, kilomita imodzi imagwirizana ndi kusintha kwa 1000 kwa chingwe choyendetsa. Kusinthasintha, gudumu loyamba lamagiya (kumapeto kwa iliyonse yaiwo pali manambala) bwalo lathunthu lathunthu likamamatira ku giya lina lokhala ndi chotchingira tsitsi, chomwe chimazungulira gawo limodzi.

Magiya aliwonse amachita zotsatirazi pakadatha kusintha 10. Makina atsopano a odometer ali ndi magiya omwe ali ndi chiŵerengero cha zida pafupifupi 1690 mpaka 1.

Electromechanical and electronic odometers

Electromechanical and electronic odometers amawerenga ma mileage momwemonso, chizindikirocho chokha chikuwonetsedwa pazowonetsa zamagetsi. Mitundu yambiri imagwiritsa ntchito maginito ndi gyro. Makina a maginito akadutsa sensa, zamagetsi zimakonza zosinthazo ndipo zambiri zomwe zikuwonetsedwa zimasinthidwa.

Njira zambiri zama odometers oterewa zimalumikizananso ndi bokosi lamagetsi. M'mitundu ina, odometer yamagetsi imagwirizanitsidwa ndi gawo loyang'anira, lomwe limalemba zosintha zamagudumu oyendetsa (mwachitsanzo, mu dongosolo la ABS).

Pali openda zamagetsi zamagetsi. M'malo mwa maginito gyro, amagwiritsa ntchito chojambulira chowoneka ndi gudumu loyenda. Chiwerengero cha makilomita omwe amayenda chimatsimikiziridwa ndi ma aligorivimu ophatikizidwa mu chipinda chowongolera, pomwe chizindikiro cha digito chimatumizidwa pazenera la odometer.

Odometer ndi Speedometer: Kodi pali kusiyana kotani?

Popeza makina othamanga ndi odometer ndi ofanana, ndipo zisonyezo zawo zimawonetsedwa mu selo imodzi pagululi, oyendetsa magalimoto ambiri amakhulupirira kuti ichi ndi chinthu chimodzi. M'malo mwake, izi ndi zida zosiyanasiyana zomwe zikuwonetsa zotsatira zosiyanasiyana. Mawindo othamanga amafunika kuti mupimitse kuthamanga kwagalimoto. Pamene makina akupumula, singano ya chida sichimasuntha.

Ponena za odometer, mawilo akamazungulira, samawonetsa kuthamanga kwa izi, koma mtunda womwe galimoto idakwaniritsa nthawi yonse yogwira ntchito komanso panthawi ina.

Kuwonongeka kwa odometer

Zoyipa za chipangizochi ndizochepa, chifukwa chimakhala ndi njira zochepa zomwe zimakhala ndi nkhawa pamakina kapena pamagetsi. Zipangizo zamakina zimawonongeka nthawi zambiri chifukwa cha kapangidwe kake. Mumitundu yamagetsi komanso yosakanikirana, kuwonongeka kumalumikizidwa makamaka ndi kulephera kwa sensa yomwe imawerenga kasinthasintha ka gudumu.

Mukamagula galimoto pamsika wachiwiri, muyenera kudziwa kaye ngati mileage idapotozedwa ndi mwiniwake wakale. Zosankha zakuzindikira zachinyengozi zafotokozedwa mu ndemanga yapadera.

Ngati mtundu wakale walephera, kukonzanso kuyenera kuchitika mosamala komanso mosamala momwe zingathere, popeza ngakhale zolakwika zazing'ono (mwachitsanzo, kukonza kauntala sikunakonzedwe molondola) kungakhudze kwambiri kulondola kwa chipangizocho.

Ndikosavuta kwambiri ndikamagetsi zamagetsi - ngati ikasweka, ndiye kuti yatsopano imalumikizidwa ndi zolumikizira zadongosolo lino. Ngati pali kulephera mu gawo lolamulira, sizingatheke kuthetsa vutoli palokha, chifukwa zida zofunikira zaukadaulo zidzafunika kuti zithetse cholakwikacho.

Zomwe zimayambitsa kuwonongeka ndi kukonza

Kuwonongeka ndi ntchito yolakwika ya odometer imadalira mtundu wa mita. Odometer yodalirika kwambiri ndi yamagetsi, yolumikizidwa mosalekeza ndi kompyuta yomwe ili pa bolodi. Nawa kusweka kofala kwa mitundu yosiyanasiyana ya odometers:

1. Mechanical mita amalephera chifukwa cha kuvala kwa magiya ndi mbali zina zamakina. Pakachitika ngozi, chingwe cha odometer chikhoza kuthyoka kapena makinawo amatha kusweka, chifukwa chomwe mita sichigwira ntchito bwino kapena kuyimitsa kwathunthu.
2. Ma odometer amagetsi amakanika amatha kulephera ngati kulumikizana kutayika pakati pa mita ndi sensa yamagudumu. Nthawi zambiri, microchip ya chipangizocho imawonongeka.
3. Ma odometer amagetsi nthawi zambiri amasiya kugwira ntchito moyenera chifukwa chosokoneza pulogalamu, mwachitsanzo, poyesa kupotoza mtunda.

Chifukwa chiyani kubwereranso kuwerengera mtunda m'galimoto

Pali chifukwa chimodzi chokha chopotoza mtunda wagalimoto. Njirayi imakulolani kuti mubise mkhalidwe weniweni waumisiri wagalimoto. Mwachitsanzo, woyembekezera wogula amasokeretsedwa za moyo wa injini, kufala ndi machitidwe osiyanasiyana omwe amayenera kusinthidwa ndi mtunda wautali.

Kupotoza mtunda, wogulitsa akhoza mwina amanena kuti injini akadali kutali makilomita miliyoni (nthawi zambiri Motors ayenera kukonzanso chachikulu). Kapena mosemphanitsa, akhoza kutsimikizira kuti galimoto wadutsa mtunda wochepa chabe pambuyo kukonzanso wagawo mphamvu.

Pazochitika zonsezi, cholinga chachinyengo chotere ndicho kugulitsa galimoto yokongola kwambiri pamtengo wapamwamba. Mileage yochepa ndi chifukwa chachikulu chomwe eni ake agalimoto osadziwa amavomereza mtengo wokwera kwambiri wagalimoto yogwiritsidwa ntchito.

Kupotoza - kukonza kwa odometer

Njirayi imagwiritsidwa ntchito ndi eni magalimoto osawona mtima omwe akukonzekera kugulitsa galimoto yawo. Chifukwa cha izi ndikulephera kuyika ndalama pagalimoto, koma kufunitsitsa kothandiza ndalama zochulukirapo pogulitsa.

Galimoto iliyonse ikayenda mtunda winawake imafunika kuisamalira nthawi zonse, osati chifukwa chongofuna kupanga. Njira ndi machitidwe atatha nthawi yina amafunika kukonzedwa, ndipo nthawi zina amatha kusinthidwa.

Wogula mwanzeru akasankha galimoto yomwe wagwirako ntchito, amasamala momwe galimoto ilili, kuphatikiza kuyang'ana odometer. Ngati mileage ili yabwino, ndiye kuti imakonza nthawi yomwe kukonza kudachitika. Kuti asocheretse kasitomala, ena amapotoza kubwerera mmbuyo kuti apereke chithunzi chakuti njirayi ikadali kutali kwambiri. Zina, m'malo mwake, zimangothamanga, motero wogula ali ndi lingaliro loti MOT idachitidwa kalekale.

Zili zotheka kugula galimoto yokhala ndi zopindika - zokhala ndi odometer yamakina. Ndizovuta kwambiri kuchita izi ndi mnzake wamagetsi. Kuti muchite izi, muyenera kulowererapo pulogalamu yoyang'anira, chifukwa chake, mukamagula galimoto ngati iyi, ndikofunikira kuti muzichita zozama pakompyuta.

Pakufufuza, katswiri nthawi yomweyo adzawona kusiyana pakati pa zomwe zili pakompyuta. Mwachitsanzo, pa board board memory ikhoza kukhala ndi uthenga wonena za cholakwika chilichonse chokhala ndi mileage ya 105, ndipo pakuwunika kwa odometer iwonetsa 000, ndipo mwiniwake wamagalimoto amatsimikiza kuti palibe amene wachita chilichonse ndi zamagetsi. Ndi bwino kukana "zopereka zokopa" zoterezi.

Kuti mumve zambiri zamomwe mungazindikire momwe galimoto idagwiritsidwira ntchito, onani kanema:

Momwe mungadziwire mileage yeniyeni pa AUTO

Kukonzekera kwa kauntala ya electromechanical

Ngati pulse sensor yaikidwa mu gearbox kuti mudziwe mtunda wa galimoto, ndiye kuti kusintha mawerengedwe a mita, ubwino wake umapanga mafunde, omwe ali:

• Zithunzi za 1006VI1;
• Ma capacitor awiri a ceramic;
• Awiri MLT 0.125 resistors (ngati resistors zotere sangapezeke, mukhoza m'malo ndi SMD resistors mtundu);
• Chosinthira chimodzi cha P2K;
• Diode KD521 kapena chofananira chomwe chimatha kugwira ntchito ndi ampere imodzi. Izi zidzateteza mphepo ngati kusintha kwa polarity kwa dera kumaloledwa;
• Mtundu umodzi wamtundu wa "amayi", womwe umayikidwa pagulu la zida m'malo mwa wowongolera liwiro. Apo ayi, dera lamagetsi liyenera kudulidwa;

Dera lokha limapangidwa motere:

1. Zotsutsa zimagulitsidwa ku bolodi;
2. Ma capacitors amagulitsidwa ku bolodi;
3. Zolumikizira za board zimalumikizidwa ndi ma jumper opangidwa ndi mawaya. Zomaliza zomwe kusinthaku kumalumikizidwa kumagulitsidwanso pano.
4. Kotero kuti mapangidwewo ndi chidutswa chimodzi ndipo mawayawo saduka, amavulazidwa ndi tepi yamagetsi.

Kukonza odometer yamagetsi

Pankhaniyi, zambiri za mtunda woyenda ndi galimoto zimasungidwa mu kukumbukira microprocessor wa unit control. Ndizosatheka kufafaniza kapena kusintha zizindikiro izi. Kaya nambala yotani yomwe odometer ikuwonetsa pa dashboard, polumikiza zida zowunikira, chizindikiro chenicheni chidzadziwika.

Kuwongolera odometer mumtundu uwu wa mamita kumachitika kokha ngati gulu la zida likusintha chifukwa cha kuwonongeka kwa chishango.

Momwe mungapangire chowongolera ndi manja anu

Popeza kukumbukira kwa odometer sikuchotsedwa, kuti musinthe magawo a odometer, muyenera kusokoneza dashboard ndikuchotsa bolodi lokumbukira. Kwenikweni, kukumbukira kumayikidwa pafupi ndi microprocessor pa bolodi lomwelo. Kuyendetsa kumagulitsidwa. Kusintha deta mu kukumbukira kwake, udindo kuwerenga odometer, muyenera kulumikiza microcircuit kwa mapulogalamu.

Amakhala ndi:

• Mabodi;
• Zotsutsa zitatu (zilizonse ziyenera kupangidwira kukana kwa 4.7 kOhm.);
• Wopanga mapulogalamu amalumikizidwa kudzera pa COM output. Cholumikizira ichi chimalumikizana ndi waya wofiira kapena wakuda. Chinthu chachikulu si kusokoneza mizati. Mukalumikiza, muyenera kukumbukira kuti waya wofiyira ndi kulumikizana kwabwino, ndipo wakuda ndi woyipa.

Ndi chiyani chinanso chofunika kuti tikonze?

Koma ndi chinthu chimodzi kusonkhanitsa wopanga mapulogalamu, chinanso kulumikiza ku chip chachizolowezi. Izi zidzafuna mapulogalamu apadera pa kompyuta. Akatswiri ena amagwiritsa ntchito pulogalamu ya Ponyprog. Zowona, pulogalamuyi sigwira ntchito bwino pamakompyuta onse. Pankhaniyi, mungagwiritse ntchito analogi ake.

Komanso, kuti muyike bwino mtunda, mudzafunika chowerengera chapadera cha mapulogalamu. Mwachitsanzo, chowerengera cha TachoSoft mileage kapena chofanana nacho. Mwambiri, chowerengera ichi chimamasulira ma odometer (nambala) kukhala code yapadera. Ndi mawonekedwe awa kuti chidziwitsochi chimasungidwa mu kukumbukira kwa unit control unit.

Njira yosinthira zizindikiro

Ndi pulogalamu yoyenera komanso wopanga mapulogalamu, mutha kupitilira njira yosinthira ma odometer. Zotsatira zake ndi izi:

1. Wopanga mapulogalamu amalumikizidwa ndi kompyuta;
2. Zothandizira zimayambitsidwa pakompyuta;
3. Mu pulogalamu ya Ponyprog, kupanga, chitsanzo cha galimoto ndi chaka chopangidwa zimalowetsedwa. Mukalowa izi, pansi pawindo mudzawona nambala yomwe ili ndi chidziwitso cha mtunda wa galimoto, yomwe imasungidwa kukumbukira gawo lolamulira.
4. Chowerengera cha mileage chimayamba. Lili ndi kuwerenga kwa odometer komwe mukufuna. Zomwe zimagwiritsidwa ntchito zimamasulira nambala iyi kukhala nambala ya hexadecimal.
5. Chotsatiracho chimalowetsedwa mu galimoto m'malo mwa code yapitayi.
6. Pambuyo pa kusintha, galimotoyo imayikidwanso pa bolodi. Chishango chimasonkhanitsidwa motsatira dongosolo.

Ngati kuwongolera kung'anima pagalimoto kunapambana, nambala yomwe mukufuna idzawunikira pa odometer. Pochita ntchito yotereyi, kusamala kwambiri kumafunika, chifukwa microcircuit imatha kuwonongeka panthawi ya soldering.

Kodi kukonza odometer kumawononga ndalama zingati?

Ngati mwiniwake wa galimoto ali ndi kulimba mtima kuti akonze odometer yamagetsi, ndiye kuti mtengo wa nkhaniyi umadalira mtengo wa zinthu zomwe pulogalamuyo iyenera kupangidwira komanso kupezeka kwa pulogalamuyo. Ndi kudzikonza mtunda, pali mwayi waukulu wowononga kukumbukira odometer.

Pachifukwa ichi, njirayi iyenera kuchitidwa ndi akatswiri omwe ali ndi chidziwitso chokwanira pakukonzekera magalimoto. Kutengera dera, mtengo wowongolera kuwerengera kwa odometer ndi $40. Komanso, chitsanzo cha galimoto chimakhudzanso mtengo wa ndondomekoyi.

Kugwiritsa ntchito odometer kudziwa mtunda wa galimoto yogwiritsidwa ntchito

Popeza odometer imakhala ndi ma module awiri, omwe amawonetsa mtunda wonse wagalimoto ndi "mtunda watsiku ndi tsiku" (woperekedwa ndi dalaivala yekha kupita ku gawo lomwe akufuna, mwachitsanzo, kudziwa mtunda kuchokera ku mfundo imodzi kupita ku ina), mtunda wonsewo. chizindikiro chingatithandize kudziwa ngati kugula galimoto ntchito kapena ayi.

Pofufuza galimoto pamsika wachiwiri, kuwerenga kwa odometer ndi chinthu chofunikira kwambiri pozindikira "zaka zamakono" za galimoto (pazaka, galimotoyo ikhoza kukhala yatsopano, koma pamtunda wa makilomita zidzasonyeza kuti galimotoyo yatha kwambiri. ).

Zoonadi, pamsika wamagalimoto ogwiritsidwa ntchito masiku ano, pali makope ambiri okhala ndi ma mileage. Munkhani yapadera akufotokoza mwatsatanetsatane chifukwa chake ogulitsa amachita izi. Ndipo apa mndandanda wa zitsanzo umaperekedwa, mtunda umene nthawi zambiri sagwirizana ndi zomwe zalengezedwa pamene zimagulitsidwa pamsika wachiwiri.

Ngati chitsanzo chokhala ndi odometer yamakina chimasankhidwa, ndiye kuti zonse ndi zachisoni kwambiri apa. Mapangidwe ake ndi osavuta kotero kuti ngakhale munthu yemwe si katswiri amatha kubweza mtunda m'njira yoti zisawonekere. Zikatero, muyenera kuganizira zizindikiro zosalunjika za kuvala kwa galimoto ndikudalira umboni wa kuyesa kuyesa.

Pankhani ya odometer yamagetsi, kukwera kwa mileage kumakhala kovuta kwambiri. Kuti muchite izi, muyenera kulowererapo kukumbukira gawo lowongolera. Ngati makinawo ayeretsedwa koteroko, ndiye kuti palibe zolakwika zonse ndi umboni wakuti katswiri wagwira ntchito pa unit control. N'zosatheka kuti panthawi yoyendetsa galimotoyo palibe vuto limodzi la ECU.

Pazifukwa izi, muyenera kusankha galimoto ndi mayunitsi angapo ulamuliro, mwachitsanzo, kuti pali zina kufala ECU, ABS, etc. Nthawi zambiri cholakwika chimodzi cha sensor chimakonzedwa ndi magawo osiyanasiyana owongolera. Chifukwa chake, kuwunika kwamakompyuta kumatha kuwulula kusiyana pakati pa zizindikiro za ma ECU osiyanasiyana

Kanema pa mutuwo

Kanemayu akuwonetsa momwe kuwerenga kwa odometer kumawongoleredwa ndi outbid:

Kukonza mtunda. Momwe mungapititsire ma mileage.

Mafunso ndi Mayankho:

Kodi manambala pa odometer amatanthauza chiyani? Pali masikelo awiri pa odometer. Wina amawerengera mtunda wathunthu wagalimoto. Lachiwiri limatchedwa "mileage ya tsiku ndi tsiku". Pali batani lokonzanso lachiwiri. Kauntala imeneyi imalola kuti dalaivala azitha kuyang'anira mileage yakomweko. Mwachitsanzo, anthu ena, kutengera ma mileage omwe adayenda, amadziwa nthawi yopumira mafuta mgalimoto (mumitundu ina ya LPG palibe sensa yosonyeza kuchuluka kwa mafuta omwe atsala).

Kodi pali kusiyana kotani pakati pa odometer ndi othamanga? Speedometer ndiyeso yokhala ndi muvi (mu mtundu wakale). Chipangizochi chikuwonetsa liwiro lomwe galimoto ikuyenda mphindi inayake. Makinawo akangoima, muvi umawonetsa mtengo wochepa (wagona poyimilira). Odometer imayesa mtunda woyenda.
