He aha te pūoko hāora o mua o te motuka?
Ko te pūoko hāora o mua o te motuka he pūoko hāora kua tāutahia ki mua i te kaitahuri catalytic ara-toru. Ko tana mahi matua he kite i te kukū hāora i roto i te hau putanga o te miihini, me te tuku i ngā mōhiohio kite ki te ECU (wae whakahaere hiko) i roto i te ahua o ngā tohu hiko. Ka whakahaerehia e te ECU te nui o te werohanga wahie i roto i te porowhita kati e ai ki te kukū hāora i roto i te hau putanga hei whakatika i te ōwehenga hau-wahie o te ranunga kia tata ai ki te uara ariā, kia pai ake ai te whai huatanga o te tahunga me te whakaiti i te parahanga tukunga.
Ko te kaupapa mahi o te pūoko hāora o mua e ahu mai ana i ngā ngongo uku zirconia, he irahiko konukawata porous kua whakamahanahia ki ngā taha e rua. I tētahi pāmahana, nā te rerekētanga o ngā kukū hāora i ngā taha e rua, ka honoa ngā ngota hāora i te taha kukū teitei ki ngā irahiko i runga i te irahiko konukawata hei hanga i ngā katote hāora, kia pai ai te utu o te irahiko, ā, ka heke ngā katote hāora ki te taha kukū hāora iti mā roto i te irahiko, kia kino ai te utu o te irahiko, ka puta he rerekētanga pūmanawa. Ina angiangi te ranunga, he nui te ihirangi hāora i roto i te putanga hau, ā, he iti te rerekētanga pūmanawa. Ina kukū te ranunga, he iti te ihirangi hāora i roto i te putanga hau, ā, he nui te rerekētanga pūmanawa. Ka whakatikatika te ECU i te werohanga wahie kia rite ki tēnei rerekētanga pūmanawa mō te whakahaere porowhita kati.
Kei mua i te pūwhakawhitiwhiti ara-toru te pūoko hāora o mua, ā, ko te nuinga o te wā ka kitea te kukū hāora i roto i te hau putanga o te mīhini. Mena he ōrite ngā raraunga i kitea e te pūoko hāora o mua me te pūoko hāora o muri, tera pea he tohu kei te raru te pūwhakawhitiwhiti ara-toru, me tirotiro me te tiaki.
Ko te mahi matua a te pūoko hāora o mua o te motuka he kite i te nui o te hāora i roto i te putanga hau o te miihini, me te huri i ēnei mōhiohio hei tohu hiko hei tuku ki te rorohiko miihini (ECU), kia tutuki ai te whakahaere porowhita kati o te ōwehenga hau-wahie. Ina koa, ka aroturukihia e te pūoko hāora o mua te kukū hāora i roto i te putanga hau, hei āwhina i te ECU ki te whakarite i te nui o te weronga wahie, te pupuri i te ōwehenga hau-wahie pai rawa atu, te whakapai ake i te whai huatanga o te wahie, te whakaiti i te whakapaunga wahie, me te whakaiti i ngā tukunga o ngā hau kino pēnei i te hauota waro (CO) me ngā waikura hauota (NOx).
Te kaupapa mahi
He rite te mahi a te pūoko hāora o mua ki te pākahiko, ā, ko tōna wāhanga matua ko te huānga zirconia, e mahi ana i ngā pāmahana teitei, ā, ka whakakorikoria e te konukawata. Ka whakamahia e te pūoko te rerekētanga kukū hāora i waenga i te roto me te waho o te zirconia hei whakaputa i te rerekētanga pūmanawa, ā, ki te nui ake te rerekētanga kukū, ka nui ake te rerekētanga pūmanawa. He iti te kukū o te hāora i roto i te hau putanga ki te kukū o te hāora i roto i te āhuarangi, ā, ka puta he tohu ngaohiko i waenga i ngā irahiko i tēnei rerekētanga kukū. Ka whakatikatika te ECU i te werohanga wahie kia rite ki ēnei tohu, kia mōhio ai kei te tata te ōwehenga hau-wahie o te ranunga ki te uara tino pai o te ariā.
Tūnga tāutanga
Ko te pūoko hāora o mua ka tāutahia i mua i te whakakorikori-toru, ā, ka whakamahia hei kite i te kukū hāora i roto i te hau putanga o te mīhini. Ko te pūoko hāora i muri i te whakakorikori-toru ka tāutahia i muri i te kaitahuri whakakorikori-toru hei kite i te kukū hāora o te hau putanga i muri i te purenga whakakorikori. Mena he rite ngā raraunga kukū hāora i whiwhihia e te pūoko hāora i mua me muri, tera pea he tohu kua rahua te kaitahuri whakakorikori-toru.
Pānga o te korenga
Ki te kore e mahi te pūoko hāora o mua, ka raru pea te tere koretake me te nui o te wahie e pau ana. Nā te mea kāore e taea e te ECU te whakarite i te werohanga wahie i runga i te tohu kukū hāora tika, ka heke te mahi a te miihini, ka kino ake hoki ngā tukunga.
