torque curve vs the torque curve

Both 'torque curve' and 'the torque curve' are correct, but they are used in different contexts. 'Torque curve' is commonly used in technical discussions or when referring to a specific curve, while 'the torque curve' is used when emphasizing a particular torque curve among others or when introducing the concept.

torque curve

This phrase is correct and commonly used in technical discussions or when referring to a specific curve.

This phrase is used to describe the graphical representation of the torque output of an engine or motor over its range of operation.

Examples:

The torque curve of this engine peaks at 3000 RPM.
Understanding the torque curve is essential for optimizing performance.
The shape of the torque curve can vary depending on the engine design.
Analyzing the torque curve helps in selecting the right gear ratios.
The torque curve provides valuable information about the engine's power delivery.
