He aha ngā whitiki wā?

He whitiki matotoru ngā whitiki wā, he mea hanga ki te rapa, he niho mārō, he koki kei roto, hei āwhina i a rātou ki te hono i ngā wira porowhita o ngā toki porowhita me ngā toki kame. E whakamahia ana ēnei hei whakakaha me te whakahaere i ngā mahi a ngā papu wai, ngā papu hinu, me ngā papu weronga, e ai ki te hoahoa o te miihini. E whakamahia whānuitia ana ēnei i roto i ngā miihini tahu ā-roto hei whakatuwhera me te kati i ngā takirere o te miihini i roto i te wā tika.

 

He aha ngā whakamahinga o ngā whitiki taima?

Ko ngā whitiki taima tino whai hua ēnei whakamahinga me ngā mahi e whai ake nei:

He mea nui tēnei hei whakahaere angitu i te tukanga tahunga mā te whakahaere pai i te piston me ngā takirere.

Ka whakahaerehia e ia te mahi a te takirere mā te hono i te poro crankshaft me te poro camshaft.

Ka tiakina e ia te whakatuwheratanga me te katinga whakauru o ngā takirere o te miihini.

Ka whakakorea te hiahia mō te pūngao o waho hei whakahaere i te whakatuwheratanga me te katinga o ngā takirere mā te whakamahi i te pūngao miihini o te miihini tahu.

Ko tētahi o ngā mahi me ngā whakamahinga matua o ngā whitiki taima ko te aukati i te piston kei pā kino ki ngā takirere.

Ahakoa he whitiki kotahi, he taputapu rānei, he nui tana āwhina ki te whakahaere i ngā wāhanga maha pērā i te pihi o te kakau taurite o runga, te pihi o te kakau taurite o raro, te taputapu taraiwa whitiki porowhita, te taputapu taraiwa whitiki taurite, te roera whakapūmau whitiki taurite, me te roera whakapūmau whitiki wā.

 

He aha te tikanga mahi a ngā whitiki wā?

Ka whakatauritea e ngā whitiki wā te mahi kati-tuwhera me ngā wā o te porowhita, te porowhita kame, me te takirere putanga. Ka āwhina i te whakaurunga wahie me te hau ki roto i te miihini tahu, me te whakahaere hoki i te takirere putanga kia puta te paoa, te putanga rānei. Ka pupuri te whitiki i te miihini kia taurite, ā, ka pupuri i tōna kaha me tōna hua.

 

Āhea te wā hei whakakapi i te whitiki wā?

Ko te putanga mai o ēnei tohu he tohu mō te hiahia kia whakawhitia te whitiki tawhito me te whitiki kua pakaru, kia whakakapia hoki ki tētahi whitiki wā hou:

Te mana o te miihini kua whakaitihia

Te wera rawa o te miihini

Te puta o ngā wiri, te rūrū rānei i roto i te mīhini

He uaua ki te tīmata i te mīhini, i te waka rānei

Ngā haruru mirimiri, ngā haruru rānei e puta mai ana i te whitiki

Ka puta te tangi o te miihini

Te turuturu hinu mai i te miihini

Te koretake o te mahi a te rama miihini
