Kdy\u017e se rozsv\u00edt\u00ed kontrolka motoru, je d\u016fle\u017eit\u00e9 m\u00edt protokol pro diagnostiku.

1. Diagnostick\u00fd postup a testovac\u00ed metody<\/h3>\n\n\n\n
Prvn\u00edm krokem k \u0159e\u0161en\u00ed potenci\u00e1ln\u00edho probl\u00e9mu s katalyz\u00e1torem je d\u016fkladn\u00e1 diagnostika.

K\u00f3d P0420 je siln\u00fdm indik\u00e1torem probl\u00e9mu s katalyz\u00e1torem. Dobr\u00fd technik se v\u0161ak t\u00edmto nezastav\u00ed. Provede tak\u00e9 vizu\u00e1ln\u00ed kontrolu katalyz\u00e1toru a v\u00fdfukov\u00e9ho syst\u00e9mu, zda nevykazuj\u00ed zn\u00e1mky fyzick\u00e9ho po\u0161kozen\u00ed. Dal\u0161\u00ed \u00fa\u010dinnou metodou pro kontrolu ucpan\u00e9ho katalyz\u00e1toru je test zp\u011btn\u00e9ho tlaku. Ten zahrnuje instalaci tlakom\u011bru do portu lambda sondy pro m\u011b\u0159en\u00ed tlaku v\u00fdfukov\u00fdch plyn\u016f. Vysok\u00fd tlak je jasn\u00fdm znakem ucp\u00e1n\u00ed.<\/p>\n\n\n\n
Tento komplexn\u00ed p\u0159\u00edstup je z\u00e1sadn\u00ed, proto\u017ee p\u0159\u00edznaky selh\u00e1n\u00ed katalyz\u00e1toru lze \u010dasto zam\u011bnit s jin\u00fdmi probl\u00e9my.

Diagnostick\u00fd postup zaji\u0161\u0165uje identifikaci a opravu skute\u010dn\u00e9ho probl\u00e9mu, \u010d\u00edm\u017e se p\u0159edejde zbyte\u010dn\u00fdm oprav\u00e1m a n\u00e1klad\u016fm.<\/p>\n\n\n\n

Pokud je v\u0161ak katalyz\u00e1tor \u010d\u00e1ste\u010dn\u011b zablokovan\u00fd nebo kontaminovan\u00fd usazeninami uhl\u00edku, m\u016f\u017ee b\u00fdt profesion\u00e1ln\u00ed \u010di\u0161t\u011bn\u00ed sch\u016fdn\u00fdm \u0159e\u0161en\u00edm.

V\u00fdm\u011bna je trvalej\u0161\u00edm \u0159e\u0161en\u00edm a \u010dasto je jedin\u00fdm zp\u016fsobem, jak zajistit, aby vozidlo spl\u0148ovalo emisn\u00ed po\u017eadavky.<\/p>\n\n\n\n
3.OEM vs. aftermarket servisn\u00ed \u0159e\u0161en\u00ed<\/h3>\n\n\n\n
Pokud jde o v\u00fdm\u011bnu katalyz\u00e1toru, firmy maj\u00ed dv\u011b hlavn\u00ed mo\u017enosti: d\u00edly od v\u00fdrobce origin\u00e1ln\u00edho vybaven\u00ed (OEM) nebo aftermarketov\u00e1 \u0159e\u0161en\u00ed. Katalyz\u00e1tory origin\u00e1ln\u00edho vybaven\u00ed (OEM) jsou identick\u00e9 s t\u011bmi, kter\u00e9 byly dod\u00e1ny s vozem z tov\u00e1rny.

Obvykle jsou v\u0161ak dra\u017e\u0161\u00ed variantou.<\/p>\n\n\n\n
Dodavateln\u00e9 katalyz\u00e1tory jsou dostupn\u011bj\u0161\u00ed alternativou. Dod\u00e1vaj\u00ed se ve dvou hlavn\u00edch typech: univerz\u00e1ln\u00ed a katalyz\u00e1tory pro p\u0159\u00edmou mont\u00e1\u017e. Univerz\u00e1ln\u00ed katalyz\u00e1tory jsou levn\u011bj\u0161\u00ed, ale vy\u017eaduj\u00ed sva\u0159ov\u00e1n\u00ed a \u00fapravy, co\u017e m\u016f\u017ee b\u00fdt \u010dasov\u011b n\u00e1ro\u010dn\u00fd proces.
