What is the amount of air a cylinder draws in on the intake stroke?

The amount of air a cylinder draws in during the intake stroke is primarily determined by the cylinder's displacement, the engine speed, and the atmospheric pressure. This volume can be calculated using the formula for the cylinder's displacement (π/4 × bore² × stroke) and taking into account the engine's volumetric efficiency. Typically, at a given engine speed and under ideal conditions, a cylinder can draw in close to its full displacement volume of air. However, in practical scenariOS, factors like intake restrictions and engine design may reduce this amount.
