Abstract The research status of variable geometry combustion chamber at home and abroad is summarized in this
article. The structure of variable geometry in combustion chamber includes air splitter, swirler, dilution hole and flame
stabilizer. The concept of variable geometry provides a flexible control of the possibility of internal airflow distribution in
the combustion chamber, providing new breakthroughs in reducing engine exhaust emissions, improving combustion efficiency,
and maintaining stable and reliable combustion chamber operation.
