Chiar \u0219i un mic zgomot poate deveni o defec\u021biune catastrofal\u0103 a motorului dac\u0103 este ignorat, deoarece exist\u0103 multe piese mici, relativ ieftine, care sunt vitale. Mai mult, chiar \u0219i cele mai mici piese defecte ale motorului sau transmisiei pot duce la \u00eenlocuirea \u00eentregului motor.<\/p>\n

Din p\u0103cate, chiar \u0219i cu o \u00eentre\u021binere riguroas\u0103, pot ap\u0103rea diverse probleme. Unele dintre cele mai grave probleme ale motorului \u0219i transmisiei care apar din neglijarea \u00eentre\u021binerii regulate a ma\u0219inii \u0219i ignorarea semnelor evidente de probleme sunt:<\/p>\n

    O inspec\u021bie vizual\u0103 simpl\u0103 ar trebui s\u0103 fie primul pas \u00een diagnosticarea unei probleme, deoarece este rapid\u0103 \u0219i poate dezv\u0103lui multe probleme imediat. Tot ce trebuie s\u0103 faci este s\u0103 ridici capota \u0219i s\u0103 verifici atent urm\u0103toarele semne:<\/p>\n

      \n
    • Scurgeri<\/strong>. Nu ar trebui s\u0103 existe scurgeri \u00een compartimentul motorului. Asigur\u0103-te c\u0103 motorul \u0219i accesoriile acestuia sunt uscate.<\/li>\n
    • Furtune deteriorate sau sl\u0103bite<\/strong>. Furtunele de radiator, direc\u021bie asistat\u0103 \u0219i de admisie aer ar trebui s\u0103 fie intacte, f\u0103r\u0103 cr\u0103p\u0103turi sau rupturi vizibile.<\/li>\n
    • Cabluri deteriorate sau oxidate<\/strong>. Izola\u021bia cablurilor poate fi deteriorat\u0103 atunci c\u00e2nd acestea freac\u0103 de alte suprafe\u021be. Acest lucru se \u00eent\u00e2mpl\u0103 adesea c\u00e2nd clipsurile de sus\u021binere sunt rupte sau lipsesc. De asemenea, umiditatea excesiv\u0103 poate cauza oxidarea \u0219i afectarea conexiunilor.<\/li>\n
    • Belturi uzate sau deteriorate<\/strong>. Ar trebui s\u0103 vezi c\u00e2teva curele de accesorii \u00een fa\u021ba motorului. Acestea sunt folosite pentru a alimenta alternatorul, compresorul AC, pompa de ap\u0103 \u0219i pompa de direc\u021bie asistat\u0103, iar dac\u0103 o curea de accesoriu este deteriorat\u0103, aceste sisteme pot func\u021biona defectuos sau se pot opri complet.<\/li>\n
    • Corodare<\/strong>. Verific\u0103 dac\u0103 toate piesele metalice \u0219i \u021bevile sunt intacte.<\/li>\n<\/ul>\n

      De asemenea, po\u021bi testa motorul \u00een timp ce este pornit \u2013 acest lucru ajut\u0103 s\u0103 verifici dac\u0103 curelele sunt sl\u0103bite sau dac\u0103 exist\u0103 scurgeri de fluide sub presiune. Totu\u0219i, dac\u0103 exist\u0103 o problem\u0103 serioas\u0103 cu motorul, pornirea acestuia poate cauza daune suplimentare, a\u0219a c\u0103 fii precaut.<\/p>\n

      Verificarea nivelului de fluide<\/h3>\n

      Ma\u0219inile folosesc diferite tipuri de fluide, iar majoritatea sunt accesibile \u00een compartimentul motorului \u2013 uleiul de motor, lichidul de r\u0103cire, lichidul de fr\u00e2n\u0103, lichidul de direc\u021bie asistat\u0103 \u0219i lichidul pentru sp\u0103l\u0103torul de parbriz.<\/p>\n

      Uleiul de motor este unul dintre cele mai importante fluide dintr-o ma\u0219in\u0103 \u2013 reduce uzura motorului, capteaz\u0103 contaminan\u021bii \u0219i distribuie c\u0103ldura. Lichidul de r\u0103cire asigur\u0103 c\u0103 motorul \u0219i componentele acestuia func\u021bioneaz\u0103 la temperaturi optime, iar lichidul de fr\u00e2n\u0103 \u0219i cel de direc\u021bie asistat\u0103 sus\u021bin sistemele hidraulice.<\/p>\n

      Asigur\u0103-te c\u0103 verifici aceste fluide lunar sau dup\u0103 ce observi ceva \u00een neregul\u0103. C\u00e2nd nivelurile sunt sub minim, probabil exist\u0103 o scurgere care trebuie remediat\u0103. De asemenea, fii atent la culoarea fluidelor \u2013 dac\u0103 uleiul de motor este alb-cremos \u00een loc de maro sau negru, probabil c\u0103 garnitura de cap este ars\u0103. Lichidul de r\u0103cire ar trebui s\u0103 fie colorat luminos, nu alb, negru sau maro.<\/p>\n

      Dac\u0103 motorul a fost \u00een func\u021biune, a\u0219teapt\u0103 cel pu\u021bin jum\u0103tate de or\u0103 dup\u0103 oprirea acestuia pentru a evita s\u0103 te arzi atunci c\u00e2nd verifici fluidele.<\/p>\n

      Verificarea zgomotelor \u0219i mirosurilor neobi\u0219nuite<\/h3>\n

      \u00cen mod normal, fiecare component\u0103 a motoarelor moderne este proiectat\u0103 aproape perfect, f\u0103c\u00e2ndu-le silen\u021bioase \u0219i line. C\u00e2nd ceva se sl\u0103be\u0219te sau se rupe, anumite componente pot \u00eencepe s\u0103 se loveasc\u0103 \u00eentre ele, s\u0103 se frece, sau s\u0103 cauzeze supra\u00eenc\u0103lzire, scurgeri \u0219i alte probleme notabile.<\/p>\n

      Dependen\u021ba exclusiv\u0103 de sunete atunci c\u00e2nd diagnostichezi o problem\u0103 este adesea un \u201eghicit\u201d, dar po\u021bi totu\u0219i s\u0103 \u00ee\u021bi dai seama c\u00e2t de grav\u0103 este problema. Zgomotele de frecare sunt adesea legate de curele sl\u0103bite sau uzate, iar zgomotele joase sau de m\u0103cinare pot fi cauzate de lubrifiere deficitar\u0103 sau de componente interne sl\u0103bite ale motorului. Sunetele de lovire pot \u00eensemna mai multe lucruri, de la supape deteriorate p\u00e2n\u0103 la ardere inegal\u0103 a combustibilului. Oricum ar fi, zgomotele neobi\u0219nuite indic\u0103 adesea probleme majore care trebuie abordate corespunz\u0103tor.<\/p>\n

      Fii atent \u0219i la mirosurile ciudate. Acestea apar din cauza supra\u00eenc\u0103lzirii motorului, sistemului de evacuare deteriorat sau din cauza scurgerii \u0219i picur\u0103rii diferitelor fluide pe p\u0103r\u021bile fierbin\u021bi ale motorului. Nu toat\u0103 lumea poate diferen\u021bia mirosurile fiec\u0103rui fluid, prin urmare, \u021bine cont de faptul c\u0103 mirosurile de ars indic\u0103 o situa\u021bie poten\u021bial periculoas\u0103, \u00een timp ce mirosul de gaze de e\u0219apament \u00eenseamn\u0103 c\u0103 exist\u0103 o scurgere \u00een sistemul de evacuare.<\/p>\n

      \u00cen concluzie, dac\u0103 observi orice zgomote sau mirosuri ciudate \u0219i nu e\u0219ti sigur ce se \u00eent\u00e2mpl\u0103, nu-\u021bi asuma riscuri, opre\u0219te motorul \u0219i contacteaz\u0103 un mecanic.<\/p>\n

      Scanarea codurilor de eroare<\/h3>\n

      De\u0219i aceasta este singura parte a test\u0103rii motorului care necesit\u0103 un instrument, un scanner OBD-II merit\u0103 din plin investi\u021bia. De ce? Pentru c\u0103 ma\u0219inile moderne pot avea peste 100 de unit\u0103\u021bi de control, fiecare control\u00e2nd motorul, trenul de rulare, sistemul de fr\u00e2nare, infotainmentul \u0219i multe alte sisteme. C\u00e2nd ceva nu func\u021bioneaz\u0103 corect, unit\u0103\u021bile de control identific\u0103 acest lucru ca o problem\u0103 \u0219i activeaz\u0103 coduri de eroare specifice pe care le po\u021bi descifra folosind aceste cititoare de coduri.<\/p>\n

      \"\"<\/p>\n

      De obicei, atunci c\u00e2nd exist\u0103 o problem\u0103 cu motorul, pe bord apare un semnal luminos portocaliu de \u201echeck engine\u201d (verific\u0103 motorul). Totu\u0219i, acest semnal lumineaz\u0103 doar pentru a te avertiza c\u0103 exist\u0103 o problem\u0103 cu motorul, a\u0219a c\u0103 trebuie s\u0103 afli mai multe detalii conect\u00e2nd un scanner OBD-II.<\/p>\n

      Dac\u0103 ai sau urmeaz\u0103 s\u0103 cumperi un scanner OBD-II, ob\u021binerea codurilor de eroare este simpl\u0103: conectezi instrumentul la ma\u0219ina ta (portul este de obicei situat sub bord), porne\u0219ti contactul \u0219i selectezi op\u021biunea \u201ecitire coduri eroare\u201d.<\/p>\n

      Re\u021bine c\u0103 cititoarele de coduri doar dezv\u0103luie codurile de eroare \u0219i le pot \u0219terge, dar nu rezolv\u0103 problemele. Acestea sunt instrumente care ajut\u0103 la diagnosticarea problemei, dar mecanicul trebuie s\u0103 o repare ulterior.<\/p>\n

      Teste de performan\u021b\u0103<\/h3>\n

      Exper\u021bii auto spun adesea c\u0103 nu ar trebui s\u0103 cumperi o ma\u0219in\u0103 second-hand f\u0103r\u0103 a o testa la volan, deoarece multe probleme apar doar \u00een timpul condusului. A\u0219adar, indiferent dac\u0103 cumperi o ma\u0219in\u0103 folosit\u0103 sau doar diagnostichezi propria ta ma\u0219in\u0103, un drum scurt poate face minuni.<\/p>\n

      C\u00e2nd frecarea \u00een transmisie cre\u0219te din cauza lichidului uzat sau a lipsei acestuia, po\u021bi chiar mirosi piese de metal care ard.

      Dac\u0103 conduci o ma\u0219in\u0103 cu transmisie manual\u0103, este posibil s\u0103 \u00eent\u00e2mpini probleme cu ambreiajul, care vin la pachet cu propriile lor sunete specifice. De exemplu, atunci c\u00e2nd volanta este uzat\u0103, po\u021bi auzi zgomote de cioc\u0103nit. Aceste zgomote sunt mai puternice la pornirea \u0219i oprirea motorului, dar ar trebui s\u0103 scad\u0103 sau s\u0103 dispar\u0103 atunci c\u00e2nd ap\u0103\u0219i pedala de ambreiaj.<\/p>\n

      Teste de performan\u021b\u0103 pe drum<\/h3>\n

      Diferite m\u0103rci de ma\u0219ini proiecteaz\u0103 transmisii diferit, pun\u00e2nd accent pe anumite propriet\u0103\u021bi \u0219i caracteristici. Prin urmare, acestea func\u021bioneaz\u0103 diferit \u0219i necesit\u0103 mai mult\u0103 aten\u021bie pentru a testa corespunz\u0103tor transmisia unei ma\u0219ini. Totu\u0219i, c\u00e2nd transmisia \u00eencepe s\u0103 se comporte ciudat, de obicei po\u021bi observa c\u0103 exist\u0103 o problem\u0103.<\/p>\n

      Haide\u021bi s\u0103 analiz\u0103m cum ar trebui \u0219i cum nu ar trebui s\u0103 func\u021bioneze transmisia automat\u0103 \u0219i manual\u0103.<\/p>\n

      Transmisie automat\u0103<\/h4>\n

      Cutii de viteze automatice moderne CVT \u0219i DSG sunt incredibil de line \u0219i pot schimba aproape f\u0103r\u0103 \u00eentreruperi, \u00een timp ce cutiile de viteze tradi\u021bionale mai vechi pot fi un pic mai primitive. Totu\u0219i, ele nu ar trebui s\u0103 loveasc\u0103, s\u0103 \u00eent\u00e2rz\u00e2ie schimbarea treptelor sau s\u0103 schimbe neprev\u0103zut. Re\u021bine c\u0103, \u00een timpul accelera\u021biilor bruste, schimb\u0103rile de vitez\u0103 sunt \u00eent\u00e2rziate pentru a c\u00e2\u0219tiga mai mult\u0103 putere \u0219i agilitate, \u00eens\u0103 schimb\u0103rile de vitez\u0103 sunt, de obicei, mult mai lente c\u00e2nd conduci cu vitez\u0103 constant\u0103 la viteze regulate<\/p>\n

      \"\"<\/p>\n

      Una dintre cele mai comune probleme ale transmisiei automate este un convertizor de cuplu uzat. C\u00e2nd conduci, observ\u0103 tura\u021bia motorului (RPM). C\u00e2nd transmisia nu se schimb\u0103 \u0219i men\u021bii aceea\u0219i vitez\u0103, asigur\u0103-te c\u0103 tura\u021bia motorului nu fluctueaz\u0103; altfel, este posibil ca convertizorul de cuplu s\u0103 fie uzat \u0219i s\u0103 necesite \u00eenlocuire.<\/p>\n

      Comportamentul problematic al transmisiei poate fi cauzat \u0219i de lipsa lichidului de transmisie, solenoide defecte, senzori defectuo\u0219i sau daune mecanice. Oricum, repara\u021biile la transmisie sunt adesea complexe \u0219i ar trebui realizate de exper\u021bi.<\/p>\n

      Transmisie manual\u0103<\/h3>\n

      Transmisiile manuale sunt semnificativ mai simple dec\u00e2t cele automate, dar \u00eemp\u0103rt\u0103\u0219esc multe probleme similare. C\u00e2nd sunt utilizate corect, o transmisie manual\u0103 ar trebui s\u0103 fie, de asemenea, lin\u0103. Po\u021bi observa sunete neobi\u0219nuite atunci c\u00e2nd ceva se rupe sau c\u00e2nd un rulment e\u0219ueaz\u0103, un zgomot de b\u00e2z\u00e2it de tonalitate joas\u0103 atunci c\u00e2nd cutia de viteze are lichid insuficient \u0219i unele trepte pot deveni dificile de schimbat atunci c\u00e2nd componentele interne ale transmisiei sunt uzate sau c\u00e2nd exist\u0103 o problem\u0103 cu ambreiajul.<\/p>\n

      Vorbind despre ambreiaj, \u0219oferii adesea interpreteaz\u0103 incorect problemele cu cutia de viteze ca fiind probleme ale ambreiajului. Unele piese ale unui ambreiaj dureaz\u0103 30.000 de km, \u00een timp ce altele pot dep\u0103\u0219i 100.000 de km. De aceea, mul\u021bi \u0219oferi \u00eenlocuiesc doar piesele uzate ale ambreiajului, \u00een loc s\u0103 \u00eenlocuiasc\u0103 \u00eentreaga unitate, ceea ce face ca problemele cu ambreiajul s\u0103 fie mai frecvente.<\/p>\n

      Av\u00e2nd \u00een vedere c\u0103 motorul \u0219i transmisia sunt sistemele cheie ale majorit\u0103\u021bii ma\u0219inilor, testarea \u0219i monitorizarea regulat\u0103 a performan\u021bei acestora nu doar c\u0103 asigur\u0103 longevitatea ma\u0219inii tale, dar \u0219i protejeaz\u0103 experien\u021ba ta de conducere.<\/p>\n

      Totu\u0219i, re\u021bine c\u0103 ace\u0219ti pa\u0219i sunt doar pentru un control ini\u021bial \u2013 o inspec\u021bie am\u0103nun\u021bit\u0103 ar trebui realizat\u0103 de un expert \u00eenainte de a face repara\u021bii, iar o verificare a istoricului vehiculului ar trebui implementat\u0103 atunci c\u00e2nd cumperi o ma\u0219in\u0103 second-hand. Oricum, nu ignora semnele c\u0103 ceva nu este \u00een regul\u0103 \u0219i r\u0103m\u00e2i \u00een siguran\u021b\u0103.<\/p>\n<\/div>\n
