What is meant by engine displacement?

Engine displacement refers to the total volume of all the cylinders in an internal combustion engine, typically measured in liters or cubic centimeters (cc). It indicates the engine's size and capacity to draw in air and fuel for combustion, impacting its power output and efficiency. Larger displacement often correlates with more power, while smaller displacement engines may prioritize fuel efficiency. Displacement is a key factor in determining an engine's performance characteristics.
