How it works

  1. 1Per cyl = π/4 × bore² × stroke ÷ 1000 = π/4 × 86² × 86 ÷ 1000 ≈ 499.56 cc
  2. 2Total = per cyl × cylinders = 499.56 × 4 = 1,998.23 cc
  3. 3Convert: 1,998.23 cc = 2 L ≈ 121.9 ci (1 ci = 16.387 cc)
Displacement is the total volume swept by pistons between TDC and BDC. Bore ≈ stroke is a "square" engine; longer stroke favors low-end torque, bigger bore favors high rpm. The marketed 2.0L is usually 1998 cc (e.g. 86×86 inline-4). US cars use ci (5.7L ≈ 350ci). Turbocharging does not change displacement - it densifies intake air.
