Description

Technical Field

[0001] The utility model relates to the technical field of EGR valve processing, in particular to an EGR valve processing device. Background Art

[0002] The EGR valve is an important component in the exhaust system of a car engine. Its function is to redirect a portion of the exhaust gas back into the combustion chamber to mix with the fresh incoming air to reduce the combustion temperature and reduce the generation of nitrogen oxides (NOx).

[0003] When the engine is running under high load and high temperature conditions, the combustion process will produce high concentrations of nitrogen oxides, which are harmful to the environment and human health. The EGR valve introduces a certain proportion of exhaust gas from the exhaust system, mixes it with fresh air and then sends it back into the combustion chamber, thereby reducing the combustion temperature and reducing the generation of nitrogen oxides.

[0004] The EGR valve needs to be fixed during processing, but in the prior art, the EGR valve is fixed by bolts. However, the disassembly and assembly efficiency of the EGR valve fixed by bolts is low, which affects the processing efficiency of the EGR valve. Utility Model Content
