Ko ngā amp cranking (CA) i roto i te pākahiko motuka e pā ana ki te nui o te iahiko ka taea e te pākahiko te tuku mō te 30 hēkona i te32°F (0°C)me te kore e heke iho i raro i te 7.2 volts (mō te pākahiko 12V). E tohu ana i te kaha o te pākahiko ki te whakarato i te mana e ranea ana hei tīmata i te miihini motuka i raro i ngā āhuatanga paerewa.
Ngā Kaupapa Matua mō ngā Whakakaha Whakakorikori (CA):
- Kaupapa:
Ka ine ngā amp hurihuri i te mana tīmata o te pākahiko, he mea nui mō te huri i te miihini me te tīmata i te mura, inā koa i roto i ngā waka he miihini mura ā-roto. - CA vs. Ngā Whakakaha Whakakorikori Matao (CCA):
- CAka inehia i te 32°F (0°C).
- CCAka inehia i te 0°F (-18°C), ā, he paerewa pakari ake tēnei. He tohu pai ake te CCA mō te mahi a te pākahiko i te rangi makariri.
- He teitei ake ngā whakatauranga CA i ngā whakatauranga CCA nā te mea he pai ake te mahi a ngā pākahiko i ngā pāmahana mahana ake.
- Te Hiranga o te Kōwhiringa Pūhiko:
Ko te whakatauranga CA, CCA rānei teitei ake e tohu ana ka taea e te pākahiko te whakahaere i ngā tono tīmatanga taumaha ake, he mea nui tēnei mō ngā miihini nui ake, mō ngā āhuarangi makariri rānei e hiahiatia ana he nui ake te pūngao hei tīmatanga. - Ngā Whakatauranga Noa:
- Mō ngā waka pāhihi: he mea noa te 400–800 CCA.
- Mō ngā waka nunui ake pēnei i ngā taraka, i ngā miihini tīhiera rānei: 800–1200 CCA pea e hiahiatia ana.
He aha te Hiranga o ngā Whakakaha Whakakorikori:
- Te Tīmatanga o te Mīhini:
Mā tēnei ka taea e te pākahiko te tuku i te kaha e tika ana hei huri i te mīhini me te tīmata pono. - Hototahitanga:
He mea nui te taurite i te whakatauranga CA/CCA ki ngā whakaritenga o te waka kia kore ai e ngoikore te mahi, e rahua rānei te pākahiko. - Ngā Whakaaro mō te Wā:
Ka whai hua ngā waka i ngā āhuarangi makariri i ngā pākahiko he teitei ake ngā whakatauranga CCA nā te ātete tāpiri e puta mai ana i te makariri.
