Problems solved by technology
At the initial stage of engine start-up, the combustion in the cylinder is insufficient, and a large amount of pollutants will be discharged. At the same time, the catalytic converter for processing emissions is still in a state of non-ignition, and the processing efficiency is very low.
In the existing technology, in order to increase the temperature of the catalyst as soon as possible to improve the conversion efficiency, electric heating is used to increase the engine load, etc., but the cost is high, and the conversion efficiency is not significantly improved

The invention discloses a device for reducing automobile exhaust emissions, which belongs to the technical field of automobile exhaust gas treatment. The device for reducing automobile exhaust emissions includes a catalytic converter, a buffer box, a compressor and an air storage tank. The inlet end of the catalytic converter is connected to the exhaust pipe, the outlet end is connected to the buffer tank, one end of the buffer tank is connected to the compressor, and the compressor is connected to the The gas storage tanks are connected to each other, and the gas storage tank is connected to the inlet end of the catalytic converter through the air return pipe, and the first switch valve is arranged on the air return pipe. The catalytic converter conversion efficiency of the device for reducing automobile tail gas emission is high and the cost is low.
Description
technical field [0001] The invention relates to the technical field of automobile exhaust gas treatment, in particular to a device for reducing automobile exhaust emissions. Background technique [0002] Automobile exhaust emission is one of the important causes of air pollution and smog. When the engine is started, the outlet of the exhaust pipe will emit pollutants such as HC, NOx, CO and particulate matter, which will affect the atmospheric environment. At the initial stage of engine start-up, the combustion in the cylinder is insufficient, and a large amount of pollutants will be discharged. At the same time, the catalytic converter for processing emissions is still in a non-ignited state, and the processing efficiency is very low. In the prior art, in order to increase the temperature of the catalytic converter as soon as possible to improve the conversion efficiency, electric heating is used, and the engine load is increased, but the cost is relatively high, and the im...
