Zomwe zimapangitsa mafuta kugwiritsidwa ntchito

Zinthu zambiri zimakhudza mafuta. Choyambirira, ndi kuwuluka mlengalenga, mphamvu ndi injini anaponya pa revs otsika. Komanso kukana kwa misewu. Mphamvu zambiri zimagwiritsidwa ntchito pakufulumizitsa musanasinthe, koma mphamvu imagwiritsidwa ntchito kuthana ndi kutsutsana ndi sing'anga. Chifukwa chake, kuti muchepetse kutulutsa kwa zinthu zovulaza kuchokera ku chitoliro cha utsi, akatswiri azachilengedwe amalimbikitsa kuti agwiritse ntchito njira yosavuta yogwirira ntchito cholembera. Mutha kuyisindikiza pachiyambi pomwe, koma mutathamanga liwiro la makilomita 30 pa ola, ndikosavuta kukhudza. Ndiye injini sizidzayenda pamwamba pa 2500 rpm. Ndipo ndizokwanira pamizinda. Injini ano ndi ntchito yabwino. Chifukwa cha jekeseni, 80% ya makokedwe pa 1200 rpm imatha kupezeka.

Kugwiritsa ntchito mafuta

Ngati injini ili ndi pulogalamu yamagetsi yosinthasintha, ndiye kuti 80% ya kukoka kumapezeka pa 1000 rpm. Izi zikutanthauza kuti palibe mpweya wofunikira poyambira mofulumirirapo. Mwa njira, malinga ndi zikhalidwe za ku Central Europe, kuthamangitsa kwa mazana kumachitika m'masekondi 30, ndipo mphamvu zomwezo zimachitika mkati mwa kusintha kwa 2000. Sizovuta kuti injini isapitirire kuthamanga. Ngati galimoto ili ndi kachipangizo kameneka, ndiye kuti mungathe kumasula phokoso lopanda pake, ndipo injini yokha, yokhala ndi jekeseni yamagetsi, imakweza pang'ono clutch kuti isayime. Mitundu yatsopano ya BMW ndi MINI tsopano ili ndi makina oyendetsa osayendetsa. Momwe mungayang'anire galimoto musanayende? Koma ndiye muyenera kulowa mu zida zapamwamba mwachangu momwe mungathere.

Ndi magiya ati omwe galimoto imagwiritsira ntchito mafuta abwino

Pa liwiro la makilomita 30 pa ola, m'pofunika kuyatsa zida chachinayi, ndi pa liwiro la makilomita 60 pa ola - lachisanu ndi chimodzi. Ndiye injini idzayenda pansi pa 2000 rpm, kugwiritsa ntchito mafuta kudzachepa kwambiri. Mwachitsanzo, 3000 rpm imagwiritsa ntchito mafuta ochulukirapo nthawi 3,5 kuposa 1500 rpm. Choncho, kuyendetsa pa liwiro la makilomita 50-60 pa ola mu zida mkulu kuchepetsa kumwa kwa 1,6-lita injini kwa malita 4-5. Njirayi ndi yothandiza pamene mlingo wa mafuta ndi zero, pamene kuli kofunikira kupirira khama lomaliza kumalo oyandikana nawo mafuta. Kuphatikiza apo, magalimoto amakono amagwiritsa ntchito Start-Stop system yomwe imangozimitsa injini panthawi yoyimitsa mwadzidzidzi.

Kugwiritsa ntchito mafuta ndikuzimitsa injini

Kuyimirira m'misewu yapamsewu komanso kutsogolo kwa magetsi osagwira ntchito kumapereka ndalama zokwana 5%. Koma apa tiyenera kukumbukira kuti kuyambira pafupipafupi kumawononga zimango, ndipo ndi bwino kuzimitsa injini pamalo oyimitsa omwe amakhala nthawi yayitali kuposa mphindi imodzi. Matayala ndi aerodynamics. Matayala otenthedwa bwino amathandiza kusunga mafuta. Opanga ambiri amalimbikitsa kukweza matayala akutsogolo ku 2,2 bar ndi matayala akumbuyo mpaka 2,3 bar pansi pamikhalidwe yokhazikika. Uku ndiye kuthamanga kwambiri kwa matayala a R16 ndi R17. Koma ambiri samayang'anira matayala kwa miyezi ingapo, kuwalola kuti achepetse kupanikizika ndikuyiwala kuti tayalalo likugwedezeka pa galimoto yodzaza. Chigawo cholumikizana chikuwonjezeka, chomwe chimapangitsa kuti pakhale kuvala komanso kugwiritsa ntchito mafuta. Choncho, kuti muyende ndi banja kuzungulira dziko ndi zinthu zachizolowezi mu thunthu, muyenera kuonjezera kuthamanga kwa tayala.

Malangizo Okhudzidwa ndi Turo

Pa mtundu uliwonse wamagalimoto ndi kukula kwamagudumu, kufunikira kwake kumatsimikizika. Mwachitsanzo, pa Focus II yokhala ndi matayala 205/55 R 17, tikulimbikitsidwa kugwiritsa ntchito bala la 2,8 matayala akumbuyo. Ndipo kwa Ford Mondeo tikulimbikitsidwa kuti tiwonjezere magudumu akumbuyo 215/50 R 17 mpaka 2,9 bar. Ndipo ndi za 10% zamafuta. Koma musanayese mawilo, muyenera kuwerenga malangizowo. Kukakamizidwa kwamakina ena kumatha kupezeka pamipangidwe inayake. Izi nthawi zambiri zimakhala pachikwama chama tanki amafuta. Kutsatira malingaliro a wopanga kumathandizira pakuchita matayala. Yonyamula, seaplane, mafuta ndi tayala mtunda. Koma koposa zonse, kuti tipewe kuwonjezeka kwa mafuta, zomwe zimayendetsa galimoto siziyenera kusokonezedwa.
