Moottorikoon

Moottorikoon refers to the displacement of an internal combustion engine. It is typically measured in cubic centimeters (cc) or liters (L). Engine displacement is the total volume swept by all the pistons of an engine in one movement of the piston from top dead center to bottom dead center. It is a key factor in determining an engine's power output and fuel efficiency. Larger engine displacements generally indicate a more powerful engine, capable of producing more torque and horsepower. However, they also tend to consume more fuel and produce higher emissions.

The displacement of an engine is calculated by multiplying the area of a cylinder's bore by the length of its stroke, and then by the number of cylinders. The bore is the diameter of the cylinder, and the stroke is the distance the piston travels within the cylinder. For example, a four-cylinder engine with a bore of 86 mm and a stroke of 86 mm would have a displacement of approximately 2.0 liters (2000 cc).

Engine displacement is a significant specification for vehicles, motorcycles, boats, and other machinery powered by internal combustion engines. It is often used as a primary indicator of an engine's performance capabilities. While displacement is a crucial metric, it is not the sole determinant of an engine's power. Other factors such as forced induction (turbocharging or supercharging), engine design, fuel injection systems, and valve timing also play vital roles in an engine's overall performance and efficiency. Therefore, comparing engines solely based on displacement may not always provide a complete picture of their capabilities.
