Jekeseni: kusakaniza kowonda / stratified charge
Ma injini amakono a petulo amakonda jekeseni wachindunji kuti achepetse kugwiritsa ntchito mafuta. Zoonadi, chowonadi cha kukhazikitsa jekeseni directement m'nyumba amalola kulamulira (malinga ndi chowerengera) moyenera kupezeka kwamafuta kumasilinda.
Zimapulumutsanso ndalama pamene injini ikugwira ntchito. pansi et pafupifupi liwiro, ndizotheka kubaya mafuta mwanjira ina popanda dalaivala kuzindikira. Ndipo apa ndipamene njira yolipirira ma multilevel imabwera.
Dziwani kuti chilembo S mu injini za Volkswagen Gulu FSI zimayimira laminate.
M'malo momangobaya mafuta nthawi zonse siteji yovomerezeka Pa injini ya 4-stroke, njira iyi yogwirira ntchito imakhala ndi kubaya mulingo wamafuta compression mphindi cycle, i.e. kenako (zindikirani kuti mafuta ena amabayidwabe poyamwa).
Zotsatira, sakanizani osati homogeneous mu silinda, chifukwa izi sizikanatheka panthawi yomwe mpweya umalowa. Mafuta yolunjika pa kadera kakang'ono pansi pa jekeseni ikatsala pang'ono kugwira moto, imalola kuchepetsa kutentha ndi kuyaka (palibe chifukwa chodzaza chipinda chonsecho). Zindikirani kuti kuchepa kwakumwa kumachitika chifukwa chakuti njirayi imachepetsa mlingo woperekedwa, kulola injini ya mafuta kuyenda ndi mpweya wochuluka, zomwe zimachepetsanso kutaya kwa kupopera (popeza mafuta ali ndi valve yothamanga kuti ayese kuchuluka kwa mafuta / oxidant osakaniza. ). Chifukwa pakakhala jekeseni wamba, mafuta / oxidizer osakaniza sayenera kukhala ndi mpweya wochuluka kuti msonkhano uyake bwino (chiŵerengero cha stoichiometric). Kuti muchepetse, kufunika kochepetsa kuchuluka kwa mpweya m'masilinda kumayambitsa "vacuum effect" pamlingo wa injini (kutayika kwamphamvu), komwe kumatenga mphamvu zake zina (ndi gulugufe lomwe limasintha modulira). Kutuluka kwa mpweya mosalekeza. Chochitika chosapezeka mu injini ya dizilo. Chifukwa chake, mumachitidwe osakanikirana, timatsegula gulugufe kwathunthu popanda mphamvu yopopa yomwe imatenga mphamvu komanso mafuta!
Tsoka ilo, jekeseniyi imabweretsa kuyaka kosakwanira kwamafuta. Kusakaniza kosakwanira kumayambitsa NOx ndi chindapusa. Ndipo injini ya dizilo ikagwiritsa ntchito fyuluta ya tinthu tating'onoting'ono, imakhala yoyera potengera mpweya wa tinthu tating'onoting'ono kuposa injini yamafuta yomwe sigwiritsa ntchito.

Aka kanali koyamba kupita patsambali. Ndizodabwitsa momveka bwino komanso mophweka! Zinapezeka kuti braking system yanga yasweka (ABS pa Range Rover Classic 200 Tdi) ndipo ndimatha kupeza zomwe sindimadziwa. Kwa wina AMENE AMADZIWA, kupatsa chidziwitso chake ndikwabwino - ZIKOMO!
