Adwumayɛ Nnyinasosɛm a Ɛfa Exhaust Catalytic Converter Ho
Adwuma nnyinasosɛm a ɛwɔ exhaust catalytic converter mu no te sɛ nea edidi so yi: Sɛ kar mu mframa a ɛyɛ hyew kɛse -fa afiri a wɔde tew nneɛma ho no mu a, ade a ɛtew ho a ɛwɔ catalytic converter no mu no ma CO, HC, ne NOx mframa ahorow no dwumadi yɛ kɛse, na ɛma oxidation-reduction chemical reactions bi nya nkɔso. Ne titiriw no, CO yɛ oxidized wɔ ɔhyew a ɛkɔ soro mu ma ɛbɛyɛ carbon dioxide a enni kɔla, a ɛnyɛ -awuduru; Wɔde HC nnuru no yɛ oxidized wɔ ɔhyew a ɛkɔ soro mu ma ɛbɛyɛ nsu (H2O) ne carbon dioxide; na NOx so tew ma ɛbɛyɛ nitrogen ne oxygen. Wɔdan mframa abiɛsa a epira yi ma ɛbɛyɛ mframa a asiane biara nni ho, na wɔnam saayɛ so tew kar no mu mframa ho.
