Engine Displacement Formulas

Understanding the different engine configurations is key to applying the correct displacement formula. The volume of each cylinder is calculated, then multiplied by the number of cylinders to determine the total displacement. Different configurations lead to different geometric calculations.

• For a typical four-stroke, in-line, or V-engine, the formula involves calculating the area of the piston multiplied by the stroke length and the number of cylinders. The calculation often incorporates a geometric factor (pi) for circular piston areas. This method is the most straightforward for common configurations.

V = π(d/2)²

L

where V = volume, d = bore diameter, and L = stroke length. Applying the values

• First, determine the area of one piston: π
  – (80 mm / 2)² = approximately 5026.55 mm².
• Next, calculate the volume of one cylinder: 5026.55 mm²
  – 90 mm = approximately 452,389.5 mm³.
• Finally, to get the total displacement for the four-cylinder engine, multiply the individual cylinder volume by the number of cylinders: 452,389.5 mm³
  – 4 = approximately 1,809,558 mm³.
• This is equivalent to approximately 1.8 liters.
