Engine E rua-patunga. parau tumu o te mahi

I teie mahana, i reira he iti tangata ohorere i roto i tenei tenenga rite te pūkaha ngingiha ā-. Miriona o ngā pūrere rerekē whakamahi ratou mo to ratou mahi. Rāwaho tenenga o tenei momo i roto i te rau tau 19, engari i meinga ai e te hiahia ki te waihanga i tētahi tikanga hou, me te pai, e taea te pei i te pūrere hangarau. I te tīmatanga, i reira e rave rahi mau hapehape, a ko te tino iti te pai. I muri, kua oti te reira ngā huringa, kua pai ake a inaianei to tatou i te whai wāhi ki te whakamahi i tenei tenenga. I roto i ngā te whakamahia te reira i roto i te motopaika hanga.

engine E rua-patunga, me, me tetahi atu pūkaha - ko te ngakau o te hangarau. Ahakoa o te momo, tona mahi tuatahi - whakarite tikanga kaupapa hono taua. Tata mohio katoa rite me te wahi ki te whakaturia te mea titiro reira, engari mahi reira, e kore e matau katoa. Na tamata ki te matau i tēnei pātai.

Ko te engines o huira hou i te maha o ngā rerekētanga, me te mea matua ko:

• He tikanga o te huringa whakahaere

E wha- me rua-patu engines. Ko te whakamutunga e te āhuatanga e tata e rua ngā wā atu te mana ki te nui ano ki te tauira e wha-rango. Ko whakaaro tenei painga e ki kia tino noho. Tuatahi, E ratou he tōtika āhua iti. Na reira, kei te whakamahia ratou i roto i ngā taiao kei hea he kotiti i roto i taimaha marama, rahi me te utu-tōtika pātai kohi wahie. hanga tenei taua pai māpele mō te whakamahi i roto i huira, poti nekeneke marama, kuku, kani mekameka, me ētahi atu

• tikanga tautauā

pea te pūkaha rangi wai ranei hū ai. I roto i te tirohanga o te rahi iti o te pūkaha e rua-patunga te maha whakaratohia reira ki te rangi-matao o. I roto i tona pūrere e hāngai katoa i ki whakaiti tona taimaha.

• rōrahi

rōrahi nui whakarato nui o te kaha.

He rongonui, economical, hua wha motors, engari kei te nui ake te maha whakamahia huira he engines e rua-patunga. Tenei manakohanga Ko e tika ana matua tapatahi hoahoa pūkaha, tona taimaha iti, iti kohi wahie. e pā ana te wāhi tōraro te ki te meka e whakakī iti o te ranunga combustible. e pā ana tēnei mita te ki puoto horoi rawakore i te ranunga whakapau hau.

Ko te parau tumu whakahaere o te pūkaha e rua-patunga e hāngai ana i runga i te huringa mahi poto, e puta i roto i te huringa kotahi o te kawau hake.

I roto i te kaupapa whakarunga i te pokapū mate raro (BDC) ki runga pokapū mate (TDC), hangaia e te kōkeke te korehau, e whakarite te homai ki te crankcase o te ranunga wahie-rangi. I tenei wāhi i roto i te wahie combustor whakaratohia e te kōpeke (ranunga). Next, te pokapū mate runga, me te ranunga rama mahi whakawhānui me neke te kōkeke whakararo ki BDC.

e kore te mea Modern engine rua-whiu nui rerekē i ona matua, i roto i te hononga ki tenei supply ara iahiko ngä wahie hou, me te puta putanga maina e pā ana ki ōrite i roto i te wae raraunga.

Na whakaaro tetahi atu kōwhiringa - engine takirere ki "pereti" momo.

I roto i te kaupapa o te kōkeke ki raro ki te piki te pēhanga crankcase, e whai wāhi ana ki te kati o te piha poppet. I tenei wa, e whakarato te kōkeke te whakatuwheratanga o tauranga whakapau, a ka rere te ranunga mahi pau i roto i te puka o haurehu whakapau ki te kaiwhiwhi. Ko te mahi i muri mai o te kōkeke ki te BDC ko te kitea o ngā tauranga karaehe, i nei mai te tiaki hou o te ranunga combustible. tonu engine E rua-patunga ona mahi. toutou te huringa te ki te whakarato i te hokohoko motopaika.

Ko te parau tumu whakahaere o te pūkaha e rua-patunga whakarite te faaohiparaa wā roa o te motopaika, rite te pūnaha he kuware, me te kore e i roto tokomaha kōrero. Ko reira ātete ki ngā āhuatanga maha (ahakoa rawakore kounga wahie hinu ranei), a he kaha nui ki te akakoromaki i ona kawenga.
