Zifukwa zazikulu za 4 zomwe tachometer ndiyofunikira pakuyendetsa galimoto

Nthawi zambiri zimangowoneka m'magalimoto otumiza pamanja, tachometer ndiyofunikira pakusonkhanitsira deta, kusintha magiya, kuchuluka kwamafuta, komanso moyo wa injini.

Magalimoto amakono, magalimoto ndi ma SUV akuyamba kudalira ukadaulo chaka chilichonse. Kuchokera pamakina achitetezo othandizidwa ndi dalaivala kupita ku pulogalamu yapamwamba yowunikira ndikusintha mafuta, madalaivala amasiku ano ndi osiyana kwambiri ndi akale. Chimodzi mwazinthu zotsalira (nthawi zambiri pamagalimoto okhala ndi zida zosinthira) ndi tachometer. M'zaka zapitazi, "tachometer" idagwiritsidwa ntchito ndi dalaivala kuti adziwe nthawi yabwino komanso yabwino kwambiri yosinthira kuchoka kumunsi kupita ku gear yapamwamba. Masiku ano, tachometer yowonera sizofunikira ngati kale, koma imakhala ndi cholinga.

Kumvetsetsa cholinga chenicheni cha tachometer

Mosiyana ndi zomwe anthu ambiri amakhulupirira, tachometer ndi yoposa geji yomwe imawonetsa kuthamanga kwa injini. Ndipotu, tachometer ili ndi dongosolo la zida zoyendetsera ntchito zomwe zimasonkhanitsa deta, zimatumiza ku ECU (gawo loyang'anira injini) ndipo zimakhudza ntchito ya machitidwe angapo odziimira okha. Mwalamulo, tachometer ndi chipangizo chomwe chimayesa kuzungulira kwa crankshaft ya injini, yomwe imayang'anira kuzungulira kwa ndodo iliyonse yolumikizira ndi pisitoni pakuyaka. Crankshaft ikazungulira madigiri 360, imamaliza kusinthika kwathunthu. Kuthamanga konse kwa kuzungulira kwa crankshaft kumayesedwa mosintha pamphindi kapena rpm.

RPM ikuwonetsedwa pa geji, yomwe nthawi zambiri imakhala pa dashboard ya dalaivala ndipo, nthawi zambiri, kumanzere. Nthawi zambiri imawonetsa manambala angapo kuyambira ziro mpaka 8 kapena 9 okhala ndi mizere ingapo pakati pa nambala iliyonse pazithunzi za analogi kapena digito. Nambala yapakati pakati pa 0 ndi 9 kwenikweni imatanthauzidwa kukhala 1,000 kuchulukitsa chiwerengerocho. Manambala omaliza omwe amawonetsedwa pa tachometer nthawi zambiri amawonetsedwa mofiira. Pamene injini ikuthamanga, muvi umaloza nambala yofanana ndi injini rpm. Muvi ukalozera ku chilemba chofiira, umatengedwa ngati "redline" kapena umagwira ntchito pamwamba pa zomwe zikulimbikitsidwa.

Podziwa ntchito ya tachometer, tiyeni tiwone zifukwa zazikulu 4 zomwe ndizofunikira kuti galimoto igwire ntchito.

1. Imajambula ndi kutumiza deta kuti ikuthandizeni kusintha galimoto yanu

Ngati muli ndi chotengera chodziwikiratu ndipo muli ndi tachometer, mudzawona kusasinthasintha mukamasuntha kuchoka pa giya yotsika kupita ku giya yapamwamba. Kutumiza kumakonzedwa kuti kukweze pa liwiro la injini yomwe wapatsidwa. RPM imayesedwa ndi tachometer ndikutumizidwa ku TCM (Transmission Control Module) kapena ECU. Zosintha zomwezo zimawonetsedwa pa geji. Ngakhale kuti sikeloyo ndi yongofuna zowonetsera, imalola dalaivala kudziwa nthawi yomwe angayembekezere kusintha.

2. Lolani madalaivala otumiza pamanja adziwe nthawi yosinthira

Sensa ya tachometer imathandizanso dalaivala kudziwa nthawi yoti asinthe zida zilizonse akamagwiritsa ntchito kutumiza kwamanja. Magalimoto ambiri, magalimoto, ndi ma SUV omwe amasuntha pamanja ayenera kusuntha kuchokera pansi kupita mmwamba pamene tachometer ikuwerenga pakati pa 3,000 ndi 4,000 injini rpm. Madalaivala nthawi zambiri amaphunzitsidwa kusuntha injini potengera kumveka komanso kuyendetsa bwino m'malo mowongolera ma tachometer, koma tachometer imagwira ntchito yofunika popereka chizindikiro chowonekera.

3. Imathandiza Kuti Mafuta Asamayende Bwino Kwambiri

Tachometer yogwira ntchito ingathandizenso omwe ali ndi ma transmission pamanja kupititsa patsogolo chuma chawo chamafuta. Opanga magalimoto ambiri amafotokozera m'mabuku a eni galimoto pa zomwe RPM injini iyenera kusinthidwa kuti igwire bwino ntchito. Kuti mukwaniritse bwino kwambiri, injini yamakono yoyaka mkati imaphatikizidwa ndi mtundu wina wa kufala kapena kufalitsa ndi chiŵerengero cha mayendedwe a axle. Kuphatikiza kwa machitidwe onse atatu osiyana amadziwika ngati sitima yamagetsi. Kusintha kovomerezeka ndi wopanga kumathandizira kusamutsa mphamvu kumawilo osakoka pang'ono. Ndi "katundu" wochepetsedwa kapena "kukoka" pa injini, mafuta ochepa amawotchedwa, zomwe zimapangitsa kuti mafuta azikhala bwino.

4. Imawonjezera moyo wa injini.

Injini yoyatsira mkati imakhala ndi magawo angapo osuntha omwe amafunikira mafuta kuti agwire ntchito. Chiwalo chilichonse chikasuntha, kukangana kumapangidwa ndi kusintha kulikonse kwa injini, ndiyeno, kutentha. Kuthamanga kwa injini (kapena kukweza RPM), kutentha kumapangidwa. Izi zikachitika, zigawo zachitsulo zomwe zimalumikizana zimatha kutentha mpaka zitayamba kutaya mafuta, zomwe zingayambitse kulephera koopsa. Pamene tachometer ndi zida zowonjezera zikugwira ntchito bwino, kutumizira kumatha kusuntha nthawi, kapena madalaivala apamanja amatha kusuntha monga momwe akulimbikitsira, kukulitsa moyo wa injini.

Tachometer imagwira ntchito yofunika kwambiri mu injini yamakono chifukwa imapita patsogolo kwambiri kuposa singano yosuntha pa geji. Ngati muwona kuti sensa ya tachometer sikugwira ntchito, ikhoza kukhala chizindikiro cha vuto laling'ono, monga sensa yosweka kapena waya wotayirira, kapena vuto lomwe lingakhale lalikulu, monga nthawi yowonongeka. Ngati mukuganiza kuti tachometer sikugwira ntchito pagalimoto yanu, funsani katswiri wamakina kuti adziwe chomwe chayambitsa vutoli kuti akonze bwino.
