In aviation engines, which component forms the boundary of the combustion space at the top of the cylinder?

The boundary of the combustion space at the top of the cylinder is formed by the cylinder head. It closes the top of the cylinder and provides the top wall of the combustion chamber, often containing the valve seats and spark plug or injector. The piston constitutes the bottom boundary, moving up and down to change the chamber volume. The crankshaft is not part of the combustion chamber boundary, and the lower piston rings are components for sealing rather than defining the chamber shape.
