Te tukanga tirotiro injector wahie

Ko te tirotiro i te huihuinga o te tira ngira ko: te tirotiro tirohanga mata, te tirotiro whakaheke, te tirotiro hiri me te tirotiro rehu, etc.

3.1 Ko te mata porotakaroa arata'i o te piha ngira me te tinana injector kia kaua e kitea te kino o te waku me nga rakuraku, a kua oti te mata o te kekeno.

3.2 Hurihia te piha o te ngira ki te 45°, toia te marere ngira ki waho o te tinana takirere tata ki te 1/3, a ka tere te paheke ki roto i te tinana takirere i raro i te mahi a tona ake papatipu me te kore e piri.

3.3 Tāutahia te injector wahie kua huihuia ki runga i te kaitatau wero wahie, me te whakatika i te pehanga o te puna he paku teitei ake i te paerewa o te whakatuwhera i te pehanga wahie o te injector wahie (te nuinga 12 ~ 14MPa teitei ake i te 3 ~ 5MPa).Mena ka piki te pehanga hinu ki te 20MPa, inehia te wa e heke iho ai te pehanga hinu mai i te 20MPa ki te 18MPa, kaua e iti iho i te 9~12s.

Ki te kore, he ngoikore te mahi hiri, a me kore e kitea he topata hinu i te taha o te poka pupuha.Karekau he kaiwhakamatau wahie injector, ka taea te whakauru tika te injector wahie kua oti te whakatika ki runga i te papu wero wahie o te miihini diesel hei whakamatautau.

3.4 Whakaritea ki te pehanga wahie werohia o te 12MPa, ka papu hinu i te tere papu tata ki te 60～70 wa/meneti.Ko te wahie kua mapuhia kia pai, kia taurite te ngota, me te tangi o te tangi oro.Karekau he ahua o te pupuhi hinu, karekau he rerenga kino huri noa i te kohao pupuha o te tinana injector.

Tuhia he pepa ma 10~20cm te tawhiti atu i te puha i raro i te injector, ka ine i te tawhiti h mai i te puha ki te poke hinu me te diameter d o te poke hinu.Kātahi ka tātai i runga i te tātai.

Kimihia te koki mai i te mahi pākoki, ka rua te koki ko te koki koki werohanga wahie.Mena kaore e taea te whakatutuki i nga whakaritenga na roto i nga mahi o runga ake nei, me whakakapi he injector wahie hou.

Hei whakamutunga, me tuhi nga mea e whai ake nei:

(1) Kia whai whakaaro ki te waehere i runga ake nei i te wa e whakamahi ana i te injector wahie ki te karo i te whakamahi he.Ki te kore, karekau e whiwhi nga whakaritenga tino pai, ka kore e tahuna te wahie, ka kore e tahuna, ka puta te paowa pango mai i te ngongo, ka moumou te wahie, ka raru te mana.

(2) I te whakatikatika i te pehanga wahie, kaua rawa e tukua te kiri me nga maihao kia tata ki te poka pupuha ka werohia e te wahie i werohia.Na te mea ka kuhu te hinu diesel pehanga nui ki roto i te kiri ka rere ki roto i nga oko toto, ka pa te kino ki te tinana o te tangata.Me aro nui kia kaua rawa e mataki i te ahuatanga o te wero wahie kia kore ai e kino nga kanohi.
