Description

technical field [0001] The invention relates to a tail gas utilization device, in particular to an automatic control device for realizing multi-stage utilization of motor vehicle tail gas, and belongs to the technical field of energy saving and environmental protection equipment. Background technique [0002] In recent decades, with the continuous consumption of global natural resources, the shortage of natural resources, especially oil and coal resources, has been triggered. Some oil-fueled internal combustion engines cause resource waste and environmental pollution problems because the oil is not fully burned during the combustion process. Therefore, various devices for improving the effective combustion of fuel and treating tail gas have emerged at the historic moment. [0003] The way to improve the effective combustion of fuel is to use multi-air and segmented injection, and the method to treat exhaust gas is to use three-way catalysis, but these traditional methods ca...

AI Technical Summary

Problems solved by technology

[0003] The method to improve the effective combustion of fuel is to use multi-air and segmented injection, and the method to treat exhaust gas is to use the three-way catalytic method, but these traditional methods cannot effectively solve the problem of resource shortage and environmental pollution.

[0004] The reuse of exhaust gas is one of the effective ways to save resources and protect the environment, but at present, the utilization of motor vehicle exhaust not only has defects such as single purpose, complex structure, and inability to realize automatic adjustment.
