What part delivers power from the engine to the drivetrain?

The crankshaft plays a crucial role in delivering power from the engine to the drivetrain. It converts the linear motion of the pistons, which is generated by combustion within the engine, into rotational motion. This rotational power is then transmitted to the drivetrain, which includes components such as the transmission and differential, ultimately enabling the vehicle to move.

In contrast, while the timing belt is essential for synchronizing the rotation of the crankshaft and camshaft, it does not directly deliver power to the drivetrain. The flywheel serves to smooth out power delivery and maintain engine momentum, but it is not primarily responsible for transferring power to the drivetrain. The camshaft, on the other hand, controls the timing of the opening and closing of valves in the engine but has no direct involvement in conveying power to the drivetrain.
