Device capable of improving energy conservation and emission reduction effect of new-energy automobile engine

Abstract

The invention discloses a device capable of improving the energy conservation and emission reduction effect of a new-energy automobile engine. In one embodiment, the device comprises a three-way catalytic converter sealing cover and a three-way catalytic converter bottom shell, and the three-way catalytic converter bottom shell is fixedly connected with one end of the three-way catalytic convertersealing cover through a flange. In the other embodiment, the device comprises a three-way catalytic converter sealing cover and a three-way catalytic converter bottom shell, and the three-way catalytic converter bottom shell is fixedly connected with the two ends of the three-way catalytic converter sealing cover through flanges. According to the first embodiment, insufficiently burnt black smokecompositions are filtered and prevented from entering a first three-way catalytic converter filter element and a second three-way catalytic converter filter element, so that the situation that the catalytic efficiency is affected due to carbonization is avoided, the pollutant emission is reduced, and the device is suitable for being used in energy conservation and emission reduction of low-emission engines. According to the second embodiment, insufficiently burnt black smoke compositions are filtered, exhaust gas is divided to two directions and passes through the first three-way catalytic converter filter element and the second three-way catalytic converter filter element to be filtered, the load of each filter element is reduced, the catalytic conversion efficiency is high, and therefore the device is suitable for being used in energy conservation and emission reduction of high-emission engines.

Description

technical field [0001] The invention belongs to the technical field of engine energy-saving devices, and in particular relates to a device for improving the energy-saving and emission-reducing effects of new energy vehicle engines. Background technique [0002] The three-way catalytic converter is the most important external purification device installed in the automobile exhaust system. It can convert harmful gases such as CO, carbon monoxide, HC hydrocarbons and NOx nitrogen oxides from automobile exhaust into Harmless carbon dioxide, water and nitrogen, to achieve the purpose of energy saving and emission reduction. However, during the use of the three-way catalytic converter, due to insufficient combustion of the engine, black smoke particles will be formed. When contacting the filter element of the three-way catalytic converter, carbonization will be formed. If this happens for a long time, it will affect the conversion efficiency of the three-way catalytic converter. ...

Problems solved by technology

However, during the use of the three-way catalytic converter, due to insufficient combustion of the engine, black smoke particles will be formed, and carbonization will be formed when it contacts the filter element of the three-way catalytic converter. If this happens for a long time, it will affect the conversion efficiency of the three-way catalytic converter. , the existing three-way catalytic converter adopts the way of intake air from one end. When the gas passes through the filter element of the three-way catalytic converter, the gas is relatively concentrated, and the exhaust gas cannot be fully catalytically converted, which is not conducive to energy saving and emission reduction.
