Yini ama-amps ebandayo ebandayo ebhethri?

I-Cold Cranking Amps (CCA)isilinganiso semvume yebhethri lokuqala injini emazingeni okushisa abandayo. Ngokukhethekile, kukhombisa inani lamanje (elinganiswe ku-AMPPs) Ibhethri elikhokhiswa ngokugcwele le-12-volt lingaletha imizuzwana engama-30 at0 ° F (-18 ° C)Ngenkathi ugcina ugesi okungenani7.2 volts.

Kungani i-CCA ibalulekile?

1. Ukuqala Amandla Esimo sezulu Esibandayo:
   • Amazinga okushisa abandayo anciphisa ukusabela kwamakhemikhali ebhethri, anciphise amandla awo okuletha amandla.
   • Izinjini nazo zidinga amandla amaningi okuqala kumakhaza ngenxa kawoyela omkhulu nokwenyuka kwengxabano.
   • Isilinganiso esiphakeme se-CCA siqinisekisa ibhethri linganikeza amandla anele okuqala injini kulezi zimo.
2. Ukuqhathanisa kwebhethri:
   • I-CCA iyisilinganiso esijwayelekile, ikuvumela ukuthi uqhathanise amabhethri ahlukene ngamakhono abo okuqala ngaphansi kwezimo ezibandayo.
3. Ukukhetha ibhethri elifanele:
   • Isilinganiso se-CCA kufanele sihambisane noma sidlule izidingo zemoto yakho noma imishini, ikakhulukazi uma uhlala esimweni sezulu esibandayo.

Ngabe ihlolwe kanjani i-CCA?

I-CCA inqunywa ngaphansi kwezimo zelebhu eziqinile:

• Ibhethri libanjiswa ku-0 ° F (-18 ° C).
• Umthwalo oqhubekayo usetshenziselwa imizuzwana engama-30.
• Amandla kagesi kufanele ahlale ngaphezu kwe-7.2 volts ngalesi sikhathi ukuze ahlangabezane nesilinganiso se-CCA.

Izici ezithinta i-CCA

1. Uhlobo lwebhethri:
   • Amabhethri e-lead-acid: I-CCA ithonywa ngokuqondile ngosayizi wamapuleti kanye nendawo ephelele yendawo yezinto ezisebenzayo.
   • Amabhethri e-Lithium: Yize angakalwanga yi-CCA, avame ukuvelela amabhethri e-acid ahola ezimweni ezibandayo ngenxa yamandla abo okuletha amandla angaguquki emazingeni okushisa aphansi.
2. Izinga lokushisa nokubanda:
   • Njengoba izinga lokushisa lehla, ukusabela kwamakhemikhali kwebhethri kuhamba kancane, kunciphisa i-CCA yayo esebenzayo.
   • Amabhethri anezilinganiso eziphakeme ze-CCA zenza kangcono ezimotweni ezibandayo.
3. Iminyaka kanye nesimo:
   • Ngokuhamba kwesikhathi, umthamo webhethri kanye ne-CCA yehla ngenxa yokuthambisa, ukugqoka, kanye nokuwohloka kwezinto zangaphakathi.

Ungayikhetha kanjani ibhethri ngokususelwa ku-CCA

1. Bheka Incwajana Yomnikazi wakho:
   • Funa isilinganiso se-CCA esinconyiwe somenzi wemoto yakho.
2. Cabanga ngesimo sakho sezulu:
   • Uma uhlala esifundeni esibanda kakhulu ubusika obubanda kakhulu, khetha ibhethri ngesilinganiso esiphakeme se-CCA.
   • Ezimweni sezulu ezifudumele, ibhethri eline-CCA eliphansi linganele.
3. Uhlobo lwemoto nokusetshenziswa:
   • Izinjini zedizili, amaloli, nemishini esindayo ngokuvamile zidinga i-CCA ephakeme ngenxa yezinjini ezinkulu kanye nezidingo eziphakeme zokuqala.

Umehluko Osemqoka: CCA vs Ezinye izilinganiso

• Umthamo wokubhuka (RC): Kubonisa ukuthi ibhethri lingaletha isikhathi esingakanani esiqinile ngaphansi komthwalo othize (elisetshenziselwa amandla e-elekthronikhi lapho i-alternator ingasebenzi).
• Ihora le-amp-ah): Imelela umthamo wokugcina wamandla webhethri ngokuhamba kwesikhathi.
• Marine Cranking Amps (MCA): Kuyafana ne-CCA kodwa kulinganiswe ku-32 ° F (0 ° C), okwenza kube ngqo kumabhethri asemanzini.
