Dizel motorda ciddi bir ar\u0131za meydana geldi\u011finde hissedilen \u00f6nsezi
\nYanman\u0131n habercisi. Dizel motor \u00e7al\u0131\u015f\u0131rken, devrin d\u00fc\u015fmesi, y\u00fck\u00fcn aniden artmas\u0131, motordan siyah duman \u00e7\u0131kmas\u0131, ya\u011f bas\u0131nc\u0131n\u0131n d\u00fc\u015fmesi ve karterden kuru s\u00fcrt\u00fcnmeye ba\u011fl\u0131 bir \u201cc\u0131v\u0131ldama\u201d sesi gelmesi, yanman\u0131n habercisidir. Bu gibi durumlarda motor derhal durdurulmal\u0131d\u0131r; aksi takdirde yatak a\u015f\u0131nmas\u0131 daha da artar, yatak yuvas\u0131n\u0131n y\u00fczeyi yap\u0131\u015f\u0131r, yatak ve yatak yuvas\u0131n\u0131n h\u0131zl\u0131 genle\u015fmesi nedeniyle k\u0131sa s\u00fcrede birbirine yap\u0131\u015farak kilitlenir ve motor s\u00f6n\u00fck kal\u0131r.
\nSilindir yap\u0131\u015fmas\u0131 \u00f6nc\u00fcs\u00fc. Silindir yap\u0131\u015fmas\u0131, genellikle ciddi su eksikli\u011fi durumunda meydana gelir; motor \u00e7al\u0131\u015fmaya ba\u015flamadan \u00f6nce silindir yap\u0131\u015fmas\u0131 g\u00f6r\u00fclmez; su s\u0131cakl\u0131\u011f\u0131 g\u00f6stergesi 100 \u00b0C'yi g\u00f6steriyorsa, g\u00f6vdeye birka\u00e7 damla so\u011fuk su damlat\u0131ld\u0131\u011f\u0131nda \u201ct\u0131slama\u201d sesi ve beyaz duman olu\u015fur ve su damlac\u0131klar\u0131 h\u0131zla buharla\u015f\u0131r. Bu durumda, motorun d\u00fc\u015f\u00fck devirde r\u00f6lantide \u00e7al\u0131\u015fmas\u0131na izin verilmeli veya ara\u00e7 s\u0131cakl\u0131\u011f\u0131 d\u00fc\u015f\u00fcr\u00fclmelidir; aksi takdirde alev an\u0131nda ortaya \u00e7\u0131karsa, pistonun ve silindir g\u00f6mle\u011finin silindire yap\u0131\u015fmas\u0131na neden olur.
\nSilindir valfinin yerinden \u00e7\u0131kmas\u0131. Valfin silindire girmesi, genellikle valf \u00e7ubu\u011funun k\u0131r\u0131lmas\u0131, valf yay\u0131n\u0131n kopmas\u0131, valf yay\u0131 yuvas\u0131nda \u00e7atlak olu\u015fmas\u0131, gaz kilidinin a\u00e7\u0131lmas\u0131 ve benzeri nedenlerden kaynaklan\u0131r. Silindir kafas\u0131 konumunda \u201cDangdang\u201d \u015feklinde bir vurma sesi (valfin pistona \u00e7arpmas\u0131) duyuldu\u011funda, \u201cCha Cha\u201d s\u00fcrt\u00fcnme sesi (valfin pistona de\u011fmesi) duyuldu\u011funda veya ba\u015fka anormal sesler e\u015flik etti\u011finde ve motorda dengesizlik ya\u015fand\u0131\u011f\u0131nda, bu durum genellikle valfin silindirden \u00e7\u0131kmas\u0131n\u0131n habercisidir. Bu durumda derhal motoru durdurun; aksi takdirde piston, silindir kafas\u0131 ve silindir g\u00f6mle\u011fi k\u0131r\u0131labilir, ba\u011flant\u0131 kolu veya \u00fcst dirsek b\u00fck\u00fclebilir, g\u00f6vde k\u0131r\u0131labilir ve krank mili k\u0131r\u0131labilir.
\n\u00d6nc\u00fc modelin vurma silindiri. Vurma silindiri, mekanik ar\u0131zalara daha fazla yol a\u00e7ar; silindir valfinin tanktan \u00e7\u0131kmas\u0131na neden olmas\u0131n\u0131n yan\u0131 s\u0131ra, \u00e7o\u011fu durumda ba\u011flant\u0131 \u00e7ubu\u011fundaki gev\u015fek c\u0131vatalar nedeniyle hizmet d\u0131\u015f\u0131 kal\u0131r. Ba\u011flant\u0131 \u00e7ubu\u011fu c\u0131vatas\u0131n\u0131n geriye do\u011fru kaymas\u0131 veya gev\u015femesi durumunda, ba\u011flant\u0131 \u00e7ubu\u011fu yataklar\u0131 aras\u0131ndaki bo\u015fluk artar; ard\u0131ndan karter par\u00e7alar\u0131ndan \u201cblah\u201d \u015feklinde bir vuruntu sesi duyulur. Bu vuruntu sesi \u00f6nce hafif, sonra giderek \u015fiddetlenir ve sonunda ba\u011flant\u0131 \u00e7ubu\u011fu c\u0131vatas\u0131 tamamen kopar ya da k\u0131r\u0131lan ba\u011flant\u0131 \u00e7ubu\u011fu ile yatak kapa\u011f\u0131 f\u0131rlayarak g\u00f6vdeyi ve ilgili par\u00e7alar\u0131 k\u0131rar.
\n\u00d6nc\u00fcl eksenin d\u0131\u015f\u0131nda. Dizel motorun krank milindeki omuz k\u0131sm\u0131nda yorgunluk \u00e7atlaklar\u0131 nedeniyle gizli hasar olu\u015ftu\u011funda, ar\u0131za belirtileri hen\u00fcz belirgin de\u011fildir; \u00e7atlaklar\u0131n geni\u015flemesiyle birlikte motor karterinden bo\u011fuk bir vuruntu sesi gelmeye ba\u015flar, vuruntu h\u0131z\u0131 artar, motor duman \u00e7\u0131kar\u0131r ve k\u0131sa s\u00fcre sonra vuruntu giderek artar, motorun titremesine, krank milinin k\u0131r\u0131lmas\u0131na ve ard\u0131ndan yang\u0131na neden olur. Bu nedenle, motor karterinden ola\u011fand\u0131\u015f\u0131 bir ses geldi\u011finde, derhal durdurulup kontrol edilmelidir.
\n\u00d6nc\u00fcl par\u00e7an\u0131n volan par\u00e7alanmas\u0131. Gizli \u00e7atlaklar ortaya \u00e7\u0131kt\u0131\u011f\u0131nda, volan (el \u00e7eki\u00e7le vuruldu\u011funda) bo\u011fuk bir ses \u00e7\u0131kar\u0131r; motor \u00e7al\u0131\u015f\u0131rken volandan vurma sesi gelir; h\u0131z de\u011fi\u015fti\u011finde ses artar ve motor sars\u0131nt\u0131s\u0131 meydana gelir. Bu noktada kontrol edilmezse, volan\u0131n aniden k\u0131r\u0131lmas\u0131na, u\u00e7an par\u00e7alar\u0131n neden oldu\u011fu yaralanmalara ve di\u011fer kazalara kolayca yol a\u00e7abilir.
\n\u201c\u00d6nc\u00fcl\u00fcn \u201dh\u0131z\u0131\u201c. Dizel motorun ortaya \u00e7\u0131kmas\u0131ndan \u00f6nceki \u201dh\u0131z\u201d, genellikle mavi duman, ya\u011f yanmas\u0131 veya h\u0131z dengesizli\u011fi gibi durumlarla kendini g\u00f6sterir. Motorun devrinin gaz kelebe\u011fi kontrol\u00fcyle ba\u015flat\u0131lmas\u0131ndan itibaren, nominal devri a\u015fana kadar h\u0131zl\u0131 bir art\u0131\u015f ya\u015fan\u0131r ve motor \u00e7ok fazla duman veya mavi duman yayar. Bu noktada, ya\u011f\u0131n h\u0131zla bo\u015falt\u0131lmas\u0131, havaland\u0131rma ve vakumu durdurmaya y\u00f6nelik di\u011fer \u00f6nlemler al\u0131nmazsa, motor devri artmaya devam eder; egzoz borusundan \u00e7\u0131kan uluma sesi ve havay\u0131 dolduran dumanla birlikte, h\u0131z kontrol edilemez hale gelir ve silindirlerin \u00e7arp\u0131\u015fmas\u0131 ciddi kazalara neden olur.<\/p>","protected":false},"excerpt":{"rendered":"
