Embodiment Construction

[0019] Present embodiment has carried out following experiment on the 1.8L Elantra car produced by Beijing Hyundai:

[0020] Before the experiment according to figure 1 The structure shown is to build a device that utilizes the waste heat of the exhaust gas of the internal combustion engine to generate gas by temperature difference. The box 3 is installed on the original exhaust pipe 7 of the internal combustion engine 1 through the flange, so that the exhaust gas can directly enter the box 3 and generate electricity for the temperature difference. Group 5 provides a high-temperature heat source, installs the heat sink group 4 on the thermoelectric power generation unit 5, uses the heat sink group 4 to cool down the other end of the thermoelectric power generation group 5 and provides a low-temperature heat source, hydrogen and oxygen generator 9, hydrogen tank 10, and oxygen tank 11. The electronic control unit 2, relay 6 and voltage regulator 8 are all arranged in the trunk ...

Abstract

The invention relates to a device and a method for preparing hydrogen and oxygen by utilizing waste heat of tail gas to perform temperature difference generation and belongs to the technical field of energy recovery of vehicle. According to the device provided by the invention, a set of temperature difference generation system and a set of hydrogen preparing, storing and supplying system are added on the basis of the maintenance of an internal-combustion engine 1 and an exhaust pipe 7. According to the device provided by the invention, a high-temperature heat source is supplied by smartly utilizing the tail gas of the internal-combustion engine, a low-temperature heat source is supplied by utilizing a radiating fin, and the temperature difference is generated on the two sides of a temperature difference generating device and the electricity is generated and supplied to a hydrogen oxygen preparing machine for preparing the hydrogen and the oxygen, so that the utilization for the waste heat of the tail gas of the internal-combustion engine is realized, the whole running efficiency of the internal-combustion engine is increased, the heating efficiency of the internal-combustion engine is increased and the generation of harmful emission, such as HC and CO, is reduced.

Description

technical field [0001] The invention provides a device and method for generating hydrogen and oxygen by using the waste heat of the tail gas of an internal combustion engine. The specific content relates to a device and method for generating hydrogen and oxygen by using the waste heat of the tail gas of an internal combustion engine through a thermoelectric power generation device and supplying it to a vehicle-mounted hydrogen and oxygen generator to produce hydrogen and oxygen on board. Device and control method. Background technique [0002] Improving the thermal efficiency of internal combustion engines has become an important trend in the development of internal combustion engines. In recent years, hydrogen internal combustion engines and hydrogen-doped internal combustion engines have been proven to achieve higher thermal efficiency and lower harmful emissions than traditional gasoline and diesel engines. However, due to the lack of hydrogen infrastructure, both pure h...
