Engine mana - hītori me te tohutohu mahi

Ki te taeraa mai o te ngingiha pūkaha ā-i mua i te pātai ka whakatika ngā kaiwhakanao rite ki te whakapiki ake i te kaha pūkaha. I hangaia te engines tuatahi ko te tino irrationally. Tata i hanga nga wahi katoa o te parahi rino ranei, hanga huarahi hohonu, e mangere me te poto-ora. Hei tauira, i roto i te pokapū o-20 engine rau pereoo hua paunatia 100 horsepower tata hawhe te ton. No te whakarite, he rite te mana waka hou nekeneke e ata iti iho i te 150 kg.

Hei whakatutuki i tenei, kaiwhakanao matua ake wae pūkaha aunoa: kato ake rauemi, alloys, whakawhanakehia, ka whakatinanahia auaha hangarau, i whakaurua tapahi-mata metallurgy me te matū. Hei tauira, te whakamahi o Pistons konumohe taea ake i te mana pūkaha e neke atu i te 20 ōrau mā te whakaiti i tona kaha taimaha me te waku. Me kï reira e kore te konumohe i roto i te puka parakore i roto i te waka e whakamahia ana, me te tono ona alloys ki te konupora, silicon, konupora me te chromium.

Ngā whakapaitanga ki te pūnaha wahie, me te pātīmata hoki nui ake te kaha o te pūkaha. Carburetors puea huringa o te momo manu, e te tīmatanga i kotahi-ruma, ka te maha-ruma. Na ka te taitahi o ngā pūnaha werohia e kua tae mai te ara roa i te monoinzhektorov aunoa ki te Iramaha hou pūnaha werohia tika.

Te taha te ara, pai ake me te pūnaha pātīmata: i interrupter hiko ohie ki microprocessors. Tetahi o te pūkaha hou kahore he kahore pūnaha hiko mana e tango ki pūkete nga tawhā katoa mo te mahi o te pūkaha - pāmahana me te mātotoru o te rangi, te tere waka, tūnga kātere, kawau hake, huri kawau, te hanganga matū o hau whakapau, me ētahi atu Ka rite ki te hua, e whakatau te pūnaha tukatuka raraunga hiko te nui ikeiketanga o te wahie ki te kia tukua ki te pūkaha, me te kau o pātīmata o ranunga wahie-rangi. Ko te kupu kua tutuki te reira i te mahi tino pai o te pūkaha penehīni.

Te whakanui ake i te kaha o te pūkaha diesel e tino maha tutuki i roto i te whakamahi o te turbocharger, e papua te rōrahi nui o rangi ki te puoto i te pūngao o ngā haurehu whakapau. Hoki, ki te whakapai ake i wahie tōtika parariraa i roto i engines diesel hou whakamahia pūnaha «Common Rail».

He maha ngā huarahi ki te faahepo i te putanga o te pūkaha ngingiha ā-. Otiia e kore e ti'a ia tatou e wareware e te wawaotanga i roto i te hoahoa pūkaha - ko reira kore anake kaua uaua, me te wa-e kai ana tukanga, engari ano hoki tino utu. Me matou taputapu mīhini nui-pū, alloys motuhake me ngā rauemi. Oia mau, ka taea ki te noho i runga i te kore kaitaraiwa katoa horo ake te pūkaha he nui i rite nei ki te hawhe uara o te motokā.

Aha e taea te mahi ki te mana pūkaha i nga wa katoa i te teitei?

Tuatahi o te katoa, kia tirohia koe e he noa tautuhinga wheketere katoa. Oil, whakamahia nei i roto i te pūkaha me fakatatau ki pokey me tohu mātauranga.

Ki te whakaiti i te parekura i runga i te horomanga rangi tūtohu te ki te whakamahi i te tātari o te kore resistance - na ka karanga "toku pai" - te pai, i reira he inaianei he kōwhiringa nui o whiriwhiringa. ai ratou rerekē i roto i te puka, rahi, tikanga o te warea, te tūtohutia rōrahi pūkaha. Nā ki te meka e nga kaihanga tātari i whāurutau mo nga momo pūkaha tino noa, e kore e te tāutanga o te tātari taua rapua e kaha nui, me te utu.

Tei hoki nui haere te mana pūkaha i runga i te whakahoutanga pūnaha whakapau. Kia mahara ki e ki te kore ko koutou motokā he pūnaha oti, he reira pai ki te tahuri ki te teihana mahi, e faaaravihi i ngā pūnaha whakapau.
