Täitemahu

Täitemahu is an Estonian term that translates to "filling volume" or "displacement volume." It is primarily used in the context of internal combustion engines to describe the volume swept by the pistons as they move within the cylinders. This volume is a crucial factor in determining an engine's power output and displacement.

The calculation of täitemahu involves the bore diameter of the cylinder (the width) and the stroke length (the distance the piston travels from its lowest to its highest point). Specifically, it is the volume of a single cylinder. The total engine displacement is then the sum of the täitemahu of all cylinders multiplied by the number of cylinders. For example, a four-cylinder engine with a täitemahu of 500 cubic centimeters would have a total displacement of 2000 cubic centimeters, or 2.0 liters.

Engine designers use the täitemahu to understand how much air-fuel mixture can be drawn into the cylinders during each intake stroke. A larger täitemahu generally allows for a greater volume of air and fuel to be burned, leading to potentially higher power and torque. However, täitemahu is not the sole determinant of engine performance, as factors like engine efficiency, turbocharging, and overall design also play significant roles. In some contexts, täitemahu can also refer to the volume of a prosthesis or other implant.
