Exhaust catalytic converter hnathawh dan
Exhaust catalytic converter hi car exhaust system-a tel a ni. Exhaust purification device a ni a, catalyst hmangin exhaust gas-a CO, HC, leh NOx te chu gas hlauhawm lo takah a chantir a ni. Catalytic converter an ti bawk. Catalytic converter hian catalyst hnathawh hnuaia oxidation, reduction, water-gas reaction, leh steam reforming reaction te hmangin gas hlauhawm pathum (CO, HC, leh NOx) te chu gas hlauhawm lo takah a chantir a: carbon dioxide, nitrogen, hydrogen, leh tui. Purification method hmang hian catalytic converter te hi oxidation catalytic converter, reduction catalytic converter, leh three-way catalytic converter ah te then theih a ni.
Environment humhalhna atana thil tul khauh tak a awm chhoh zel avangin car tam zawkah exhaust catalytic converter leh oxygen sensor dah a ni ta a ni. Engine exhaust pipe-a dah a nih chuan exhaust gas hlauhawm pathum (CO, HC, leh NOx) te chu oxidation-reduction reaction hmangin tui hlauhawm lo, carbon dioxide leh nitrogen-ah a chantir a ni. Chuvangin, three-way catalytic converter an ti bawk. A catalyst-ah hian platinum leh germanium emaw, rare earth element emaw ang chi metal hlu tak tak a awm fo thin.
