Dwuma a exhaust catalytic converter di
Exhaust catalytic converter yɛ kar mu mframa a ɛtwetwe mframa no fã. Ɛyɛ afiri a wɔde tew mframa a wɔtwe fi mu ho a ɛde ade a ɛma nneɛma yɛ kɛse di dwuma de dan CO, HC, ne NOx a ɛwɔ mframa a efi mframa mu no mu ma ɛbɛyɛ mframa a asiane biara nni ho. Wɔsan frɛ no catalytic converter. Catalytic converter no yɛ adwuma denam oxidation, reduction, water-gas reactions, ne steam reforming reactions a wɔde di dwuma wɔ catalyst adeyɛ ase de dan mframa abiɛsa a epira (CO, HC, ne NOx) no ma ɛbɛyɛ mframa a asiane biara nni ho: carbon dioxide, nitrogen, hydrogen, ne nsu. Wogyina ɔkwan a wɔfa so tew ho no so no, wobetumi akyekyɛ catalytic converters mu sɛ oxidation catalytic converters, reduction catalytic converters, ne akwan abiɛsa-kwan catalytic converters.
Esiane sɛ nneɛma a atwa yɛn ho ahyia ho banbɔ ho ahwehwɛde ahorow a emu yɛ den kɛse nti, wɔde mfiri a ɛma mframa bɔne a ɛma mframa fi mu ba ne mfiri a ɛma mframa bɔne hyehyɛ kar pii mu.

Enti, wɔsan frɛ no akwan abiɛsa-kwan catalytic converter. Mpɛn pii no, dade a ɛsom bo te sɛ platinum ne germanium, anaasɛ nneɛma a ɛho yɛ na a ɛwɔ nea ɛma nneɛma yɛ kɛse no mu.
