Pistonlar silindirlerin i\u00e7inde yukar\u0131 a\u015fa\u011f\u0131 hareket eder. Motor valfleri pistonlar\u0131n hareketinin \u00fcst\u00fcnde bulunabilir.

Egzoz motordan \u00e7\u0131kt\u0131ktan sonra hemen kapan\u0131r. Bazen ar\u0131zalanan yukar\u0131da i\u015flevlerinden bahsetti\u011fimiz valfler, ara\u00e7 i\u00e7in bir\u00e7ok sorun yaratabilir. Bu y\u00fczden yaz\u0131m\u0131z\u0131n devam\u0131nda sizler i\u00e7in derledi\u011fimiz motor valfi hasar\u0131 belirtilerini yak\u0131ndan tan\u0131yabil.<\/p>\n
T\u0131pk\u0131 araba motor ar\u0131zas\u0131na kar\u015f\u0131 an\u0131nda harekete ge\u00e7ece\u011finiz gibi , valf hasar\u0131 da h\u0131zl\u0131 bir m\u00fcdahale gerektirir. Modern ara\u00e7lar, valf hasar\u0131 olas\u0131l\u0131\u011f\u0131n\u0131 azaltan eksantrik mili motorlar\u0131yla donat\u0131lm\u0131\u015ft\u0131r; ancak eski modellerin \u00e7o\u011funda valf sorunlar\u0131 ya\u015fanabilir. Bu nedenle, arac\u0131n\u0131zda bu t\u00fcr belirtiler g\u00f6r\u00fclmesi durumunda derhal harekete ge\u00e7ebilmek i\u00e7in motor valfi sorunu belirtilerini bilmek \u00f6nemlidir. A\u015fa\u011f\u0131da bilmeniz gereken motor valfi hasar\u0131n\u0131n baz\u0131 yayg\u0131n belirtilerini listeledik.<\/p>\n
Motordan Gelen Sesleri<\/p>\n
Motordan t\u0131k\u0131rt\u0131 sesleri duyuyorsan\u0131z bunun nedeni motor valflerinin hasar g\u00f6rm\u00fc\u015f olmas\u0131 olabilir. H\u0131zland\u0131k\u00e7a bu sesler artma e\u011filimindeyse bunun nedeni valflerin a\u015f\u0131nm\u0131\u015f olmas\u0131 veya olas\u0131 bir yanl\u0131\u015f hizalama olabilir.<\/p>\n

Valf hasar\u0131n\u0131n bir ba\u015fka belirtisi de d\u00fc\u015f\u00fck motor g\u00fcc\u00fc ve performans\u0131d\u0131r. Valfler, hi\u00e7 bo\u015fluk b\u0131rakmadan veya \u00e7ok az bo\u015fluk b\u0131rakmadan m\u00fckemmel \u015fekilde oturacak \u015fekilde tasarlanm\u0131\u015ft\u0131r. Ancak ya\u011f s\u0131z\u0131nt\u0131s\u0131 durumunda bir bo\u015fluk olu\u015farak valfin yuvas\u0131n\u0131 kaybetmesine neden olabilir.<\/p>\n
Egzoz Borusundan Mavi Duman \u00c7\u0131kmas\u0131<\/p>\n
Egzoz borusundan \u00e7\u0131kan mavi duman ayn\u0131 zamanda valflerin bozuldu\u011funun bir g\u00f6stergesidir. Egzoz borusundan mavi duman g\u00f6r\u00fcyorsan\u0131z arac\u0131n\u0131zda motor sorunu olabilir. Mavi duman bir\u00e7ok soruna i\u015faret etse de, motor valfleri kesin bir sorun olabilir. Hasarl\u0131 motor valfi, ya\u011f\u0131n yanma odas\u0131na ula\u015fmas\u0131 i\u00e7in yer a\u00e7ar. Bu, yak\u0131tla birlikte ya\u011f\u0131n da yanmas\u0131na neden olur. S\u00fcr\u00fcc\u00fclerin bu durumda ayr\u0131ca ya\u011f seviyelerinin h\u0131zla d\u00fc\u015fmesiyle kar\u015f\u0131la\u015fma olas\u0131l\u0131\u011f\u0131 daha y\u00fcksektir.<\/p>\n","protected":false},"excerpt":{"rendered":"
