What is the primary movement converted by the crankshaft?

The primary movement converted by the crankshaft is linear to circular movement. In an internal combustion engine, the pistons move up and down in a linear fashion due to the pressure created during combustion. The crankshaft, which is connected to the pistons via connecting rods, converts this linear motion into circular motion. This circular movement of the crankshaft is essential for driving the engine's components, such as the flywheel and the various accessories connected to the engine, enabling the overall operation of the engine and the vehicle.

Understanding this conversion is crucial in small engine technology as it underlines the fundamental mechanics of how engines generate power and deliver it in a usable form. The crankshaft's role in this transition is vital for the effective functioning of any engine, making it a core concept in engine design and operation.
