How does the combustion chamber look like?

The combustion chamber is typically a closed space within an engine where fuel and air mix and ignite. Its shape can vary, but it often resembles a cylinder or a dome, designed to optimize airflow and maximize efficiency. The walls are usually made of durable materials to withstand high temperatures and pressures. In internal combustion engines, the chamber may also feature valves, spark plugs, and other components that facilitate the combustion process.
