Tirohanga mo nga miihini Nissan HR12DE me HR12DDR
Ko te ICE (internal combustion engine) Nissan HR12DE i tukuna i te tau 2010 e te kamupene rongonui Nissan Motors. Ma te ahua o te miihini, he rereke te ahua o te raina-a-roto, a, e 3 ngongo me nga maru 12. Ko te rōrahi o tenei miihini he 1,2 rita. I roto i te punaha piston, ko te diameter o te piston he 78 millimeters me tana whiu he 83,6 millimeters. Ko te punaha werohanga wahie kua whakauruhia ki runga i te Double Over Head Camshaft (DOHC).
Ko taua punaha ka whakatau i te whakaurunga o nga camshafts e rua ki te upoko rango (upoko rango). Ko enei hangarau hanga miihini ka taea te whakatutuki i te whakahekenga haruru tino kaha me te whiwhi mana o te 79 horsepower, me te taipana o 108 Nm. He iti noa te taumaha o te miihini: 60 kirokaramu (te taumaha o te miihini kore).
Nissan HR12DE miihini
Kua whakauruhia ki runga i nga tauira motuka e whai ake nei:
- Nissan March, restyling. Tau putanga 2010-2013;
- Nissan Note, whakahou. Tau putanga 2012-2016;
- Nissan Latio, whakahou. Tau putanga 2012-2016;
- Nissan Serena. Tau tuku 2016.
Tuhinga
Ko tenei miihini i puta mai he tino torquey, i roto i te tikanga tohatoha hau, hei utu mo te whitiki, i whakauruhia e te kaiwhakanao he mekameka o te whakanui ake i te mau kakahu, a he tata ki te kore e taea te toro atu ki runga. Ko te punaha wa he punaha huringa wahanga. Kua whakauruhia ano he katere hiko. Engari ko tetahi o nga ngoikoretanga kino ko ia 70-90 mano kiromita, ka tika ki te whakatika i nga waahi o te riipene, na te mea kaore te punaha e whakarato mo te whakaurunga o nga kaitao hiko. Ko tenei tukanga kaore e roa te wa, engari kaore i te iti rawa.
Tuning
Hei tikanga, kaore pea i te nui te kaha o te miihini auau, na reira ka taea te whakapai ake i tana mahi ma te hiko hiko, miihini ranei.
Ma te whakaraerae hiko, ka mahia te mea e kiia nei ko te maramara, engari kaua e tatari kia nui ake te kaha o te mana, mo te + 5% ki te mana miihini.
Ma te whakatikatika miihini, he maha ake nga waahi. Mo te pai ake o te kaha, ka taea e koe te whakanoho i te turbine, te huri i te tini o te ngongo, te tuku i te rere whakamua me te urunga o te hau makariri, kia piki ake koe mai i te 79 horsepower ki te 125-130.
Ko enei whakapainga te mea tino haumaru, etahi atu whakarereketanga miihini, hei tauira: te hoha o te cylinder, ka taea te ngaro o te kaha paerewa me te oranga o te waahanga.
Te tiaki
Kia roa ai te mahi o te miihini me te kore e taka, me mahi tonu te tiaki, me whakarereke nga kai pau i te waa, whakamahia te hinu e taunakihia ana e te kaiwhakanao mo tenei tauira miihini, me te whakarereke i te waa.
I tukuna ano te miihini Nissan HR12DDR i te tau 2010, i te nuinga o te waa he HR 12 DE hou. Ko te rōrahi mahi kaore i rereke, ka noho tonu ki te 1,2 rita. Mo te whakahoutanga, me tohu ko te whakaurunga o te turbocharger, kua whakahekehia hoki te kohi wahie, a kua whakakorehia te pehanga nui i roto i nga cylinders. Ko enei whakarereketanga ka taea te whakanui ake i te mana ki te 98 horsepower ka whiwhi i te taipana o 142 Nm. Ko nga tawhā matua kaore i rereke.

Nissan HR12DDR miihini
Kua whakauruhia ki runga i nga tauira motuka e whai ake nei:
- Nissan Micra. Tau tukunga 2010;
- Nissan note. Tau tukunga 2012-2016.
Tuhinga
I tino pai ake tenei miihini i te wa o te whakaputanga karekau he pakarutanga ka puta mo te kore take.
Tuning
Ko taua tauira miihini ka taea te kaha ake ma te hiko me te miihini miihini, i korerohia i runga ake nei. Engari he mea pai kia mahara ki nga rohe o te whakaurunga o taua whakahoutanga. Mena he rereke nga huringa, ka taea te ngoikore o te punaha katoa.
Te tiaki
Kia kore ai e raru ki tenei tauira miihini, he mea tika kia mau tonu te tiaki i te waa, ka huri i te hinu me nga kai pau i te waa, me te whakamahi i te hinu kounga teitei.
