Waka engine wha-patunga

Arā, o te wha ipurau pūkaha, e kua eke i runga i te crankcase me ki runga ki runga matenga kati. titia Carter paepae raro. I roto i te puoto whakaturia e vaolo upoko - te kokoru me putanga, te pupuha mo te werohanga o te wahie (Diesel) engines ranei mura pātīmata (penehīni). Roto te nekehanga kōkeke, te hono i roto i te titi kōkeke ki te matenga o runga o te tokotoko honotanga. hipoki te upoko o raro o te tokotoko honotanga te waha hautaka matua kawau hake e e eke i runga i ahunga. Te kōkeke i roto i te puoto hiri e mowhiti motuhake. I te mutunga o te kawau hake he tōhito whakaritea.

I huaina tūnga wāhi mate o runga nohoia e te kōkeke i te mutunga o tona patunga maha, ka karanga te wāhi mate raro ko te tūranga nohoia i te mutunga o te haere whakararo.

huaina te mărû e ko te kaupapa o te kōkeke i tetahi pokapū mate ki tetahi. i hanga displacement runga reira ka te kitea i te reira i TDC, te ruma ngingiha ko te tawhā. displacement pūkaha te rōrahi displacement ranei - ko te nui tukua e te kōkeke, ka neke i te wāhi mate. Ko te rōrahi o te rango - he uara tapeke o te ruma parariraa ki te mahi.

Kōpeketanga ōwehenga Ko tētahi āhuatanga nui, tautuhia nei rite te ōwehenga o te tonu rōrahi rango ki te katoa rōrahi o te ruma ngingiha. Modern engine kotahi-puoto kua he ōwehenga kōpeketanga o e pā ana ki 10. Ko te kotahi-puoto engine wha-patunga he ōwehenga kōpeketanga teitei, e kore e iti iho i te 20.

engine wha-patunga i te timatanga o te patunga horomanga ina iriti i te piha horomanga, ka te kōkeke tīmata neke i pokapū mate runga. I roto i te tukanga o te neke i te mārua i hanga i roto i te puoto me te manako engine wha-patunga he ranunga o te rangi, me te wahie kohu, e maha nei i huaina he ranunga wahie wahie-rangi ranei.

I muri i te kōkeke ka tango BDC wahi, e tika ana ki te huringa o te kawau hake, tīmata reira ki piki ki te pokapū mate runga, whakaaro nei ko te timatanga o te patunga kōpeketanga. kati tenei te piha kokoru, a puta noa i te huringa, katia e vaolo rua. Kei te kōpeke te ranunga combustible e kei roto i te puoto i te displacement o te kōkeke ki TDC, tona pāmahana me te pēhanga hua. He he he uara mōrahi, ka te kōpeketanga kōkeke TDC. Otiia mai e te tukanga wahie ngingiha etahi wa mo te ranunga combustible mura te i roto i te mua, i mua i te kōkeke tae TDC i runga i te patunga i kōpeketanga. mura te ranunga e te mura hiko e hūpeke i waenganui i nga electrodes o te plug. Mai i te wa i te mura BTDC, ka karanga te koki ratchet te koki o te precession pātīmata.

I roto i te tau nui o hau kaha-kai tukua i roto i wahie parariraa, te pēhi i runga i te kōkeke, e meinga te pūkaha ki te mahi wha huringa patunga i roto i te muri e puta ana ki te vaolo katia i kōkeke patu i TDC ki BDC. haamata whakapau patunga i muri i patu. Whakatuwhera ai, te piha whakapau me neke te kōkeke ki TDC, displacing te haurehu whakapau ki te kōhauhau. Na, i roto i te huringa raupapa taua toutou te.
