Three-stage recycling system for automobile exhaust gas

Abstract

The invention belongs to recycling devices for automobile exhaust gas, and particularly discloses a three-stage recycling system for automobile exhaust gas. The recycling system comprises a kinetic energy recycling device, a vibration energy recycling device, a thermal energy recycling device, a rectifying circuit and a DC/DC converter, wherein the kinetic energy recycling device is fixed at air outlets of an exhaust branch pipe and an air inlet branch pipe; the vibration energy recycling device is fixed to a tail section exhaust pipe; the thermal energy recycling device is fixed to an exhaust pipe which is between a middle section muffler and a tail section muffler and is close to the tail section muffler; the kinetic energy recycling device, the vibration energy recycling device and the thermal energy recycling device are connected with the rectifying circuit through conducting wires; and the rectifying circuit is connected with the DC/DC converter. According to the three-stage recycling system for automobile exhaust gas, the structure is simple and compact, kinetic energy, thermal energy and vibration energy in automobile exhaust gas can be classified and recycled, and the problem that energy in conventional automobile exhaust gas cannot be fully utilized is solved.

Description

technical field [0001] The invention belongs to an automobile waste gas energy recovery system, in particular to a three-stage recovery system of automobile waste gas energy. Background technique [0002] In recent years, with the development of the automobile industry and the continuous improvement of people's living standards, the number of automobiles in my country has also increased significantly. Automobiles consume huge energy while bringing convenience to people, and more and more attention has been paid to the energy saving of automobiles. At present, the energy utilization efficiency of automobile engines is generally not high, only about 40%, and the remaining energy is dissipated in various forms, and automobile exhaust dissipates a large part of the energy. [0003] At this stage, relevant people have done some research on the field of energy recovery from automobile exhaust gas. For example, the patent number CN103114898A, the patent name is "Automotive Exhaus...
