2008 Nissan Teana 2.0 Convertidor catalítico de tres vías

El escape del motor contiene monóxido de carbono (C0), hidrocarburos (HC) y óxidos de nitrógeno (NOX) y otros gases dañinos, y el convertidor catalítico de tres vías es un dispositivo de conversión que puede convertir estos tres gases nocivos en sustancias inofensivas. El catalítico de tres vías de ajuste directo se instala en el tubo de escape y se asemeja a un silenciador. The outer cylinder is made of double-layer stainless steel plate, the interlayer is equipped with insulation material -- asbestos fiber felt, the steel cylinder is longitudinal with dense honeycomb holes of high temperature resistant ceramic carrier (there are other shapes, such as sphere, polygonal body, mesh partition, etc.), the surface is spray with a very thin platinum, rhodium, palladium active catalytic layer as a cleaning agent (also known as catalyst).

2. El principio de trabajo

When the engine exhaust gas is discharged through the exhaust pipe, the activity of C0, HC and NOx is enhanced due to the catalysis of the purifier in the ternary exhaust pipe catalytic converter'' so as to carry out the oxidation-reduction reaction, among which, C0 is oxidized to colorless, non-toxic C02 at high temperatures,HC compounds are oxidized to H20 and C02 at high temperatures, and NOx is reduced to N2 (nitrogen) and 02 (oxygen), so that the exhaust gas emissions of el motor se purifica
