Zomwe injini makokedwe lokha

Aliyense injini ali makhalidwe ena. Ena ali kuposa wina. Tikudziwa kuti ntchito zabwino za galimoto ukusowa mphamvu zambiri, koma ochepa mukudziwa chimene makokedwe galimoto. Mwachidule - ndi mphindi mphamvu, amene anaphatikiza crankshaft kuti atembenuza mu bwalo zonse. M'pake kuganiza kuti ngati mphamvu, izo amayezedwa NM. Choncho apamwamba zigoli, galimoto zambiri zazikulu.

Koma ngati mphamvu kumawonjezera pafupifupi 5500-6000 rpm, ndi makokedwe pazipita injini kusiyana pa liwiro zolimbitsa. Koma injini dizilo, ali ngati khalidwe kwambiri kuposa mafuta, kuyambira mlingo wa psinjika mu pafupifupi kuwirikiza kawiri, tsono, pisitoni Ufumuyo mphamvu, limene kuwapereka kwa crankshaft lapansi.

Ngati kapena ayi, injini ambiri ndi "anai". buku lawo zimasiyanasiyana, koma opanga kutsatira ndendende dongosolo ili, kuyambira ndi yabwino ikani mtanda Komanso, si monga mtengo kubala monga, nkuti, "zisanu ndi chimodzi". Koma mfundo angatsutse ndi mfundo yoti kuchuluka kwa zonenepa, popanda kusintha makhalidwe ena, kumabweretsa kuwonjezeka njila mu makokedwe. Mwachitsanzo, ngati injini makokedwe, amene ali yamphamvu 4 ndi 2 malita a buku, ndi 150 NM, kuchuluka kwa chiwerengero cha masilindala 6 kulera izo ndi 225 NM. Mwachibadwa, m'pofunika kuganizira zomvetsa nkhani chifukwa mikangano ndi ena mphamvu kunja, kotero phindu ukonde imodzi-chachitatu, kuti ndiko kumaliza - 200 NM.

Makokedwe ndi mphamvu mowirikiza kuyesera kuonjezera. Chophweka njira kuchita zimenezi - kuchepetsa buku la chipinda kuyaka kapena njira zina kuonjezera pa psinjika chiŵerengero. Mu nkhani iyi, M'pofunikanso kukumbukira injini katundu, chifukwa mutu yamphamvu amangokhala alepheretse ndi studs kapena akapichi.

Njira ya chiwiri - atakhala crankshaft ndi bondo chachikulu. Pankhaniyi, injini revving kugwa komanso kusintha ndi zonenepa, chifukwa kusintha pisitoni sitiroko. Ndipotu - izi ndi kuchuluka yosavuta mu buku ntchito.

Tsopano - chiphunzitso pang'ono. Tikaonanso zambiri kuchuluka kwa zonenepa. Ndi chiyani icho kwambiri? chakuti m'nkhani yoyamba (4) mu kuphulika kuyaka chipinda amapezeka iliyonse madigiri 180. Izi zikutanthauza kuti utali wonse wa pisitoni sitiroko ntchito mphamvu lina panalembedwa. Asanu ndi yamphamvu injini kuphulika amapezeka iliyonse madigiri 90 crankshaft kasinthasintha. Pankhaniyi, mpaka pisitoni pochitika theka la anakhomedwa ntchito, pali kuphulika wina mu yamphamvu wina, crankshaft tsopano zimayenda awiri pisitoni. Pamene woyamba umalandira pansi pakati akufa, ndipo chachiwiri udzachitike unaperekeza, inaphulika ku wachitatu, ndi zina zotero. Mwachionekere, munthu mamangidwe ogwira.

Engine makokedwe - ziri ndithu mbali yofunika, amene angathe kudziwa unit wa chiwerengero. Pomaliza, tiyenera kuwonjezera kuti injini bulkier ndi makokedwe mkulu ndi mphamvu zambiri.
