Este important s\u0103 acorzi aten\u021bie oric\u0103rui sunet mai neobi\u0219nuit care provine de la motor, ro\u021bi sau transmisie. Defectele mecanice sunt \u00eenso\u021bite, de cele mai multe ori, de diverse zgomote. Acestea te pot ajuta s\u0103 identifici problema \u00eenainte chiar de a se produce o avarie major\u0103. De exemplu, iat\u0103 ce problem\u0103 ar putea fi atunci c\u00e2nd se aude un sc\u00e2r\u021b\u00e2it la motor \u0219i cum se rezolv\u0103.<\/p>\n\n\n\n

Ai sesizat c\u0103, uneori, se aude un sc\u00e2r\u021b\u00e2it la motor atunci c\u00e2nd porne\u0219ti ma\u0219ina sau c\u00e2nd accelerezi?<\/p>\n\n\n\n

Acest zgomot poate semnala o problem\u0103<\/a> serioas\u0103, dar care se poate rezolva rapid \u0219i f\u0103r\u0103 costuri foarte mari.<\/p>\n\n\n\n

Ce problem\u0103 este c\u00e2nd se aude un sc\u00e2r\u021b\u00e2it la motor?<\/h2>\n\n\n\n

\u00cen momentul \u00een care sesizezi un sc\u00e2r\u021b\u00e2it la motor, este foarte posibil s\u0103 fie din cauza curelei de accesorii. Unii numesc aceast\u0103 band\u0103 \u0219i curea de transmisie, de aceea se confund\u0103 cu o curea de distribu\u021bie.<\/p>\n\n\n\n

Cureaua de distribu\u021bie are rolul de a men\u021bine sincronizarea perfect\u0103 \u00eentre pistoane \u0219i supape. Mai exact, ea asigur\u0103 deschiderea \u0219i \u00eenchiderea supapelor la momentul potrivit, permi\u021b\u00e2nd amestecului de aer \u0219i combustibil s\u0103 intre \u00een cilindri \u0219i gazelor s\u0103 ias\u0103.<\/p>\n\n\n\n

\u00cen schimb, cureaua<\/a> de accesorii are rolul de a transmite mi\u0219carea motorului c\u0103tre diverse componente auxiliare. De exemplu, c\u00e2nd motorul genereaz\u0103 rota\u021bie, aceast\u0103 curea \u00eenv\u00e2rte alternatorul, compresorul de aer, pompa de servodirec\u021bie \u0219i \u00een unele cazuri, pompa de ap\u0103.<\/p>\n\n\n\n

Cu timpul, cureaua de accesorii se uzeaz\u0103 \u0219i \u00eencepe s\u0103-\u0219i piard\u0103 aderen\u021ba. Sau rolele pe care este a\u0219ezat\u0103 se sl\u0103besc.<\/p>\n\n\n\n

A\u0219adar, acel sc\u00e2r\u021b\u00e2it la motor pe care \u00eel auzi este produs de cauciucul curelei de accesorii care patineaz\u0103 pe suprafa\u021ba metalic\u0103 a rolelor.<\/p>\n\n\n\n

Ce trebuie s\u0103 faci c\u00e2nd se aude sc\u00e2r\u021b\u00e2it la motor?<\/h2>\n\n\n\n

\u00cen momentul \u00een care cureaua de accesorii \u00eencepe s\u0103 patineze, \u00eenseamn\u0103 c\u0103 s-a uzat. Sau rolele s-au sl\u0103bit \u0219i trebuie recalibrate. Dac\u0103 nu faci asta, riscul de a se rupe este foarte mare.<\/p>\n\n\n\n

\u201eSe poate \u00eent\u00e2mpla ca aceast\u0103 curea s\u0103 se rup\u0103 \u00een mers. Motorul ma\u0219inii nu se opre\u0219te, dar vei observa diver\u0219i martori care se aprind \u00een bord, precum bateria sau check engine. Vei vedea c\u0103 volanul devine destul de rigid, la fel \u0219i fr\u00e2na, iar aerul condi\u021bionat nu mai func\u021bioneaz\u0103. Nu vei mai putea merge foarte mult, pentru c\u0103 bateria nu se mai \u00eencarc\u0103. A\u0219adar, trebuie s\u0103 cau\u021bi rapid un loc sigur \u00een care s\u0103 opre\u0219ti<\/strong><\/em>\u201d, a explicat pentru ProMotor mecanicul Robert Marin.<\/p>\n\n\n\n

\u00cen cazul \u00een care cureaua de accesorii se rupe, bateria nu se mai \u00eencarc\u0103, servodirec\u021bia \u0219i aerul condi\u021bionat nu mai func\u021bioneaz\u0103, iar \u00een unele situa\u021bii, motorul nu mai este r\u0103cit.<\/p>\n\n\n\n

De aceea, c\u00e2nd auzi sc\u00e2r\u021b\u00e2it la motor, \u00eenseamn\u0103 c\u0103 aceast\u0103 curea de accesorii trebuie \u00eenlocuit\u0103<\/a>.<\/p>\n\n\n\n

\u201eO curea de accesorii cost\u0103, \u00een general, \u00eentre 50 \u0219i 200-300 de lei. Dac\u0103 lu\u0103m \u00een calcul \u0219i manopera de \u00eenlocuire \u0219i calibrare, atunci costul total de \u00eenlocuire al acesteia va fi \u00eentre 100 \u0219i 500 de lei. Depinde de ma\u0219in\u0103 \u0219i de c\u00e2t dureaz\u0103, efectiv, opera\u021biunea<\/strong><\/em>\u201d, a mai explicat mecanicul.<\/p>\n\n\n\n

A\u0219adar, dac\u0103 auzi sc\u00e2r\u021b\u00e2it la motor atunci c\u00e2nd porne\u0219ti ma\u0219ina sau \u00een mers, ar trebui s\u0103 faci o verificare am\u0103nun\u021bit\u0103. \u0218i, dac\u0103 e cazul, s\u0103 \u00eenlocuie\u0219ti aceast\u0103 pies\u0103.<\/p>\n\n\n\n
