Engine Displacement - Definition

Definition

Engine displacement is determined from the bore and stroke of an engine's cylinders. The bore is the diameter of the circular chambers cut into the cylinder block.

To simplify:

Examples: The 427 Chevy bore is 4.312 in, and the stroke is 3.65 in, therefore the displacement for this eight-cylinder engine is:

3.1416/4 × (4.312 in)2 × 3.65 in × 8 = 426.4 cu in

Or: (4.312 in)2 × 0.7854 × 3.65 in × 8 = 426.4 cu in

If the bore is 10 cm and the stroke is 5 cm with four cylinders, the calculation is:

3.1416/4 × (10 cm)2 × 5 cm × 4 = 1,570 cc = 1.57 liters

Famous quotes containing the word definition:

    Perhaps the best definition of progress would be the continuing efforts of men and women to narrow the gap between the convenience of the powers that be and the unwritten charter.
    Nadine Gordimer (b. 1923)

    One definition of man is “an intelligence served by organs.”
    Ralph Waldo Emerson (1803–1882)

    According to our social pyramid, all men who feel displaced racially, culturally, and/or because of economic hardships will turn on those whom they feel they can order and humiliate, usually women, children, and animals—just as they have been ordered and humiliated by those privileged few who are in power. However, this definition does not explain why there are privileged men who behave this way toward women.
    Ana Castillo (b. 1953)
