4-sitiroko injini: opareshoni

zida mphamvu mtundu uli kwambiri kusankha. Masiku ano, pali yachiwiriyo - 4-sitiroko ndi 2-sitiroko.

Features

zida mphamvu ukugwira zochokera yowonjezera mpweya pa Kutentha amene amapezeka pa poyatsira wa mafuta kulowa mkati mwa yamphamvu ya. Ambiri ali ndi maganizo kuti 4-sitiroko injini Briggs Stratton amapereka ntchito bwino. Kuti tipeze yankho mwatchutchutchu, m'pofunika kudziŵa maonekedwe a mitundu onse a ntchito.

Tiyipukuse kapangidwe ndi limagwirira udindo yogawa mpweya - izi ndi Gawo la dongosolo ndi n'kofunika kuonetsetsa kuti lubricant zigawo, poyatsira ndi mphamvu.

Tiyipukuse chipangizo transmits anakhumba kukhudzana kuwonjezera mipweya, pamene limagwirira kuti kugawira iwo akukamba petulo mu malo yamphamvu.

injini 4-sitiroko amakhala ndi mafuta ndalama, palibe osakaniza kuyaka mu utsi, ndi mlingo wochepa mkulu wa phokoso inkaimbidwa, komanso wochezeka, kotero anagula kufala kwa makampani chinkhoswe mu yopanga magalimoto.

Kodi injini awiri sitiroko

Dongosolo lonse zachokera sitiroko ntchito ndi psinjika.

The pisitoni zimakhala maudindo awiri - m'munsi ndi chapamwamba akufa mfundo. Pamene amayenda wina ndi mzake, ndipo overlapped alternately kuwomba kubwereketsa, ndiye wayamba compress mpweya amaonetsa yamphamvu ya. Panthawi imeneyi, mafuta osakaniza akutuluka doko polowera ndipo m'chipinda tiyipukuse limagwirira, zinali iye amene kenako adzakhala wothinikizidwa.

Pamene mpweya ndi mafuta nthunzi kufika pazipita psinjika chiŵerengero, ndi mphamvu ya magetsi, akubwera kuchokera mphanvu ya uyatsa iwo. Panthawi imeneyi, kuthamanga aumbike, kulimbikitsa gulu la pisitoni ku mfundo m'munsi chifukwa kuwonjezeka lakuthwa mu mpweya osakaniza kutentha. Pa gululi anatsegula kubwereketsa doko ndi mankhwala inali kuyaka. osakaniza ndi wothinikizidwa ngati upita pisitoni ndi akutembenukira kwa chipinda kuyaka, imodzi amatsegula potulukira zenera.

Zabwino ndi zoipa mbali

limagwirira amasiyana okwanira kuchuluka kwa kuipa, Pakati mowa wa mafuta, ndi ambiri ali pachabe. Ichi ndi chifukwa cha tsankho amasulidwe osakaniza nthunzi pa kutsegula munthawi yomweyo utsi ndi scavenging madoko. Tiyenera tionenso mosalekeza otaya mafuta, chifukwa ndi mbali ya mix, ndipo popanda izo sizingakhale injini. Mbali ina zoipa lagona mu mosalekeza mafuta kusanganikirana.

Kankhani-Chikoka limagwirira ali yaing'ono kulemera ndi miyeso kuposa sangathe kudzitama injini 4-sitiroko. Koma m'kupita kwa ntchito galimoto, iye akubweretsa mavuto ena, nchifukwa chake zosinthika izi wamba m'munda wa mawerengeredwe, amene limatsindika iliyonse kilogalamu owonjezera.

Kodi zinayi injini

Ndi osiyana kwambiri ndi mnzake ake mbandakucha. Mfundo 4-sitiroko injini mkombero wapangidwa ndi motsatizana madyedwe, psinjika ndi utsi sitiroko, umene anapeza ntchito yake, dongosolo valavu.

The pisitoni amatsegula polowera kupita pansi, ndiye osakaniza kuyaka akulowa yamphamvu pa nthawi yomweyo, osakaniza ntchito pambuyo kuyanjana ndi yotsala ya kapangidwe ntchito.

Njira mwadongosolo kubwereza, ku mbali zotchulidwa ndi ntchito mkombero, zidzachitika mu zonenepa onse ndi kupereka akugwira ntchito makina chifukwa kutembenuka mphamvu.

ulemu

The injini mu galimoto ochiritsira ukugwira ntchito pa maziko a zinayi siteji adzizungulira, izo zikuchitika pa magulu anayi pisitoni kapena kusintha awiri crankshaft lapansi.

4-sitiroko injini dizilo ali ndi njira zosiyana kwambiri ndi poyatsira wa osakaniza kuyaka ndi mapangidwe ake poyerekeza chimake carbureted. Chachikulu kusiyana mu zakudya sitiroko, monga yamphamvu dizilo akulowa mpweya mkangano kuti mfundo zabwino kutentha, ndipo mafuta ndi atomized mu particles mphindi uyatsa mchikakamizo cha mlingo kutentha.

4-sitiroko injini ali mu dongosolo ake mafuta sump, mfundo imeneyi ndi udindo lubricants, yeniyeni, kwa kukhalapo mpaka kalekale pa mlingo akonzedwa. Mpope mafuta limapereka nkhani za dongosolo kondomu ndi kugawira pa makoma lamkati la yamphamvu ya. Chifukwa, mikangano ya pisitoni ndi yafupika ndi mafuta woonda filimu. Special annular scraper zinthu kuteteza ingress wa mafuta madzi m'chipinda kuyaka ndi kubwerera utsi. Mu mpope uwu mafuta amagwiritsidwa ntchito mu injini ndi mphamvu 5 L / c. Nthawi zina, lubricant ndi anagawira nkhungu kuperekedwa ndi crankshaft lapansi.

Pakuti 4-sitiroko injini chimachititsa digiri ang'onoang'ono katundu, chifukwa mafuta ifika nthawi zonse ndalama chofunika, potero kuwonjezeka moyo utumiki wa limagwirira lapansi.

Pa nyengo, chimodzi chokha kusintha lubricant. Tikumbukenso kuti m'pofunika nthawi onani mlingo mafuta, ngakhale kuti simungathe mwadzidzidzi kutha. Today, opanga zafewetsako ntchito madalaivala, ndipo akukonzani ndi zitsanzo ano masensa wapadera omwe amalamulira mlingo mafuta ndi kukanena kufunika m'malo.

Chachikulu kusiyana

Monga taonera, mitundu iwiri ya galimoto ali ndi kusiyana lofunika chimene chili kondomu ya ndondomeko awiri sitiroko, ndi mafuta ndi mafuta osakaniza amene kenako kuwotchedwa. Ena njira yapadera imene kupereka mafuta crankcase, koma tanthauzo akanali yemweyo - mafuta Watenthedwa pamodzi ndi mafuta. Ngakhale Chinese 4-sitiroko injini "Lifan", komanso ina dongosolo ofanana, ndi zida ndi njira kubwerera mafuta mu m'chipinda chapadera.

lubricants

Poona kusiyana alipo mu Motors, galimoto mafuta ayenera kutsatira zofuna zosiyanasiyana:

• mafuta ndi njira zinayi sitiroko kale lubricity mkulu, zotsalira zikutsatiridwa pa nthawi;
• wina mtundu ayenera kuyaka pazipita lubricant ndi zotsatira kochepa yotsalira mu mawonekedwe a mwaye ndi phulusa.

Kumayambiriro kwa injini kuli ochiritsira distillation wa mafuta mankhwala ntchito kondomu kupanga. The zikuchokera anali chimodzimodzi options onse. Kufunika kulenga mafuta watsopano osadzuka chakuti injini 4-sitiroko ali ndi mphamvu otsika, ndi monga Motero, otsika avale ndi otsika katundu pa zigawo zikuluzikulu. Kenako malo wakhala wotopa nyimbo pang'onopang'ono kuwonjezeka liwiro pa ntchito ndi magawo wamba. Vutoli anali anathana ndi ntchito zina - zina zapadera kwa mafuta galimoto. Lero iwo kwambiri kusintha makhalidwe a lubricant lapansi.

mphamvu

Amakhulupirira kuti amphamvu kwambiri injini 2T chifukwa magwiritsidwe zonse mphamvu mafuta pa kusintha awiri wa m'dzenjewo. Izi si zoona chimodzimodzi, chifukwa chimake ili yamphamvu, monga zotsutsana ndi mtundu wina wa galimoto alibe dongosolo integral, ndi mbali zake imagwera pa kubwereketsa ndi polowera mipata, motero, buku ang'onoang'ono a mafuta combusted.

Chomasuka limagwirira kuphedwa 2T chifukwa cha ntchito monga lubricant chisakanizo cha mafuta ndi mafuta. Kugwira ntchito ndi osakaniza munali lubricant amakhala ndi kumasulidwa otsika mphamvu. Kapangidwe zinachititsa kuti akhuthule mafuta osakaniza otaya, amene chimachititsa ndithu mbali yaikulu. Choncho injini 4-sitiroko Chinese ali kuphedwa zovuta ndipo chotero, kuchuluka zazing'ono mafuta sanali kuyaka. Ndiko kuti, 2T injini muli mphamvu zambiri okha osiyanasiyana yopapatiza.
