Bore × stroke × cylinders — what makes a 2.0L a 2.0L.
Displacement = π/4 × bore² × stroke × cylinders. A 86mm bore × 86mm stroke × 4 cylinders = 1,999 cc ≈ 2.0L. Displacement roughly correlates with power output, which is why it's used for engine naming (the '5.0' in a Mustang GT means 5.0 liters).
Oversquare engines (bore > stroke) rev higher and favor horsepower — common in sport bikes and high-revving sports cars. Undersquare engines (stroke > bore) produce more low-end torque — common in trucks and diesel engines. A 'square' engine (bore = stroke) balances both.
