Final answer:
Engine displacement accurately describes the total piston swept volume. It represents the volume an engine can draw in during one engine cycle, and is a measure of engine size and potential power output.
Step-by-step explanation:
The correct answer is option b, "total piston swept volume". Engine displacement refers to the total volume of air/fuel mixture an engine can draw in during one complete engine cycle, which is usually expressed in liters or cubic centimeters (cc). It is the sum of the displacements of the engine's cylinders and gives a measure of the engine size and power potential. It is directly related to the engine's power output, as a larger displacement indicates a larger volume of air-fuel mixture can be combusted, potentially producing more power. However, engine displacement does not indicate the engine's efficiency or the power output, which are more related to the engine's design and the materials from which it is made.
The correct answer is option b) total piston swept volume. Engine displacement refers to the total volume swept by all the pistons in the engine. It is a measure of the engine's size or capacity and is typically expressed in liters or cubic centimeters (cc). The larger the displacement, the more power the engine can potentially produce.
