Ya\u011f nas\u0131l se\u00e7ilir?
\nYa\u011f piyasas\u0131na ili\u015fkin talimatlarda, markada s\u0131kl\u0131kla \u201cSAE\u201d ve \u201cAPI\u201d ibareleri g\u00f6r\u00fcl\u00fcr. \u201cSAE\u201d, ya\u011f\u0131n viskozitesini de\u011ferlendirmek i\u00e7in kullan\u0131l\u0131r ve ard\u0131ndan 5 ile 50 aras\u0131nda bir say\u0131 aral\u0131\u011f\u0131 gelir; say\u0131 ne kadar b\u00fcy\u00fckse ya\u011f o kadar viskoz, o kadar b\u00fcy\u00fckse ise o kadar seyrektir. \u201cAPI\u201d serisi, ya\u011f\u0131n kalitesini de\u011ferlendirir; \u201cS\u201d harfi benzin i\u00e7in kullan\u0131l\u0131r (\u201cQ\u201d harfi ise o \u00fclkede benzin anlam\u0131na gelir). \u201cC\u201d harfi dizel ya\u011f\u0131 ifade eder; \u0130ngilizce harflerle s\u0131ralanan seviyelerde \u201cA\u201d en d\u00fc\u015f\u00fck, \u201cG\u201d ise en y\u00fcksek seviyedir. \u201cC\u201d, \u201cD\u201d ve \u201cF\u201d gibi di\u011fer seviyeler de kullan\u0131l\u0131r; \u00f6rne\u011fin, \u201cAPI CD\u201d, dizel motorlar i\u00e7in \u201cAPI\u201d spesifikasyonuna uygun \u201cD\u201d s\u0131n\u0131f\u0131 ya\u011f\u0131 ifade eder.
\n\u00a0\u00a0\u00a0 Motor ya\u011f\u0131 viskozitesinin do\u011fru se\u00e7imi \u00e7ok \u00f6nemlidir; \u201cSAE\u201d standard\u0131nda say\u0131 ne kadar y\u00fcksekse o kadar iyidir. Bu se\u00e7im, b\u00f6lgenin s\u0131cakl\u0131k ko\u015fullar\u0131na ve araca g\u00f6re belirlenmelidir. Genel olarak, Guangdong ve di\u011fer g\u00fcney b\u00f6lgelerinde, ortalama bir otomobil motor ya\u011f\u0131 i\u00e7in \u201cSAE\u201d 30 ile 40 aras\u0131 viskoziteli ya\u011flar kullan\u0131labilir. \u201cAPI\u201d CC ve CD (dizel) veya \u201cAPI\u201d SD ve SE s\u0131n\u0131f\u0131 (benzinli) motor ya\u011flar\u0131 kullan\u0131labilir; l\u00fcks otomobiller i\u00e7in ise ya\u011f se\u00e7imi, \u00fcreticinin talimatlar\u0131na g\u00f6re yap\u0131lmal\u0131, rastgele se\u00e7im yap\u0131lmamal\u0131d\u0131r.
\n\u00a0\u00a0\u00a0 Buna ek olarak, \u201cW\u201d harfi bulunan \u00e7ok dereceli ya\u011flar\u0131n kullan\u0131m\u0131 yayg\u0131nla\u015fmaktad\u0131r. Bu ya\u011flara polimer maddeler eklenmesi sayesinde, ya\u011f\u0131n genel \u00f6zelliklerine ek olarak viskozitesi belirli bir aral\u0131kta ayarlanabilmekte; \u0131s\u0131ya maruz kald\u0131\u011f\u0131nda kal\u0131nla\u015fmakta, so\u011fukta ise incelmekte ve b\u00f6ylece motorun \u00e7al\u0131\u015fma performans\u0131 ve a\u015f\u0131nma direnci art\u0131r\u0131lmaktad\u0131r.
\n\u00a0\u00a0\u00a0 Genellikle iki bile\u015fenden olu\u015fan baz ya\u011f ve katk\u0131 maddelerinden olu\u015fur. Mineral baz ya\u011f ve katk\u0131 maddeleri kullan\u0131l\u0131r; bu katk\u0131 maddeleri aras\u0131nda metal deterjanlar\u0131, oksidasyon ve korozyon \u00f6nleyiciler, pas gidericiler, k\u00fcll\u00fc olmayan dispersanlar ve viskozite indeksi art\u0131r\u0131c\u0131lar bulunur. Ya\u011f\u0131n kalitesini art\u0131rmak, motor a\u015f\u0131nmas\u0131n\u0131 azaltmak ve sadece makinenin \u00f6mr\u00fcn\u00fc uzatmakla kalmay\u0131p, piston ve yanma odas\u0131n\u0131, ya\u011f filtresini daha temiz tutarak yolda olu\u015fan k\u00fc\u00e7\u00fck birikintileri \u00f6nlemek i\u00e7in \u00f6zel \u00f6zelliklere sahip baz\u0131 ya\u011f kimyasallar\u0131 eklenir; ayr\u0131ca yak\u0131t tasarrufu sa\u011flar, ya\u011f de\u011fi\u015fim aral\u0131klar\u0131 uzar ve ya\u011f de\u011fi\u015ftirme aral\u0131\u011f\u0131 genellikle on bin kilometreye veya daha fazlas\u0131na kadar uzar.
\n\u00a0\u00a0\u00a0 Genel olarak, y\u00fcksek h\u0131zda ve y\u00fckte benzinli motorlarda ya\u011f bas\u0131nc\u0131 d\u00fc\u015f\u00fckt\u00fcr; d\u00fc\u015f\u00fck y\u00fckte ise motor devri d\u00fc\u015f\u00fckken ya\u011f bas\u0131nc\u0131 y\u00fcksektir. Her iki durumun ya\u011f performans gereksinimleri farkl\u0131 oldu\u011fundan, motor ya\u011f\u0131n\u0131n t\u00fcr\u00fc de bu iki duruma g\u00f6re iki \u015fekilde farkl\u0131l\u0131k g\u00f6sterir: Bunlardan biri benzinli motor ya\u011f\u0131, di\u011feri ise dizel motor ya\u011f\u0131 olarak adland\u0131r\u0131l\u0131r ve bu iki ya\u011f t\u00fcr\u00fc birbiriyle kar\u0131\u015ft\u0131r\u0131lamaz. Hem benzinli hem de dizel motorlar i\u00e7in genel ama\u00e7l\u0131 motor ya\u011f\u0131 olarak kullan\u0131labilen bir \u00fcr\u00fcn piyasada mevcut oldu\u011fundan, bu ya\u011f\u0131n performans\u0131 motor ya\u011f\u0131 seviyesi 2'nin \u00f6rt\u00fc\u015fen de\u011ferlerini kar\u015f\u0131lar; bu da ya\u011f\u0131n uygulama kapsam\u0131n\u0131 belirtir ve t\u00fcm ara\u00e7lar i\u00e7in uygun de\u011fildir.<\/p>","protected":false},"excerpt":{"rendered":"
