Problems solved by technology

At the same time, when the temperature is lower than 150 ° C, the catalyst of the catalytic converter basically does not work, resulting in very serious hydrocarbon emissions during the cold start of the gasoline engine, and the high concentration of hydrocarbons emitted during cold start is blue and white. Smoke is one of the environmental problems caused by gasoline engines

Abstract

The invention discloses a sleeve-type molecular sieve hydrocarbon adsorption catalytic converter for gasoline vehicles. 6. Electric heating device 7, catalytic conversion part damping layer 8, catalytic conversion part 9, shrink tube 10, shell 11, outlet pipe 12, exhaust flange 13, through sleeve type on the basis of traditional catalytic conversion part Install HC adsorption part in series, and install electric heating device in the gap structure, effectively improve gasoline engine cold start HC adsorption treatment and CO, HC and NO x The problem of purification treatment can further improve the thermal catalytic conversion efficiency of exhaust gas, optimize the purification treatment of exhaust gas, and has the advantages of compact structure, good performance and stable operation.

Description

technical field [0001] The invention relates to the technical field of automobile tail gas treatment, in particular to a sleeve type molecular sieve hydrocarbon adsorption catalytic converter for gasoline vehicles. Background technique [0002] With the rapid development of my country's economic strength, people's quality of life continues to improve, people's demand for motor vehicles is gradually increasing, and the number of motor vehicles is increasing rapidly. The increasingly stringent emission regulations put forward higher requirements for engine emission control, and only relying on the way of internal purification to control the emission of engine exhaust pollutants can no longer meet the requirements of current emission standards and regulations. [0003] The rapid development of gasoline engines has played an important role in reducing energy consumption, but gasoline engine emissions also have a negative impact on air quality. Especially in the cold start stage...
