By using the residual gas and exhaust temperature in exhaust gas and catalytic action, the pollutants such as CO, HC and NOx in exhaust gas are converted into harmless CO2, N2 and H2O, which meet the emission standards of light vehicle countries V, VI, V and VI.
The tightly coupled catalyst is close to the exhaust outlet of the engine, and the CO and HC conversion and the exhaust temperature can be rapidly increased by low temperature ignition.
Chassis catalyst can effectively purify CO, HC and NOx in a wide air-fuel ratio window. Performance characteristics The coating is stable and adaptable to airspeed.
Good resistance to high temperature hydrothermal aging and sulfur poisoning, long service life; Tightly coupled catalysts have good cold start-up performance and high temperature hydrothermal stability.
