What key function did the double-acting engine serve?

Answer

It utilized steam pressure to drive the piston during both the forward and return strokes.

In the double-acting engine, steam pressure was applied alternately to both sides of the piston, ensuring power was delivered during both the outward and return movements, effectively doubling power output and smoothing operation.
