Which engine part transfers torque to the transmission flywheel?

The crankshaft is the engine component that transfers torque to the transmission flywheel. As the engine operates, the crankshaft converts the linear motion of the pistons into rotational motion. This rotational energy is then delivered to the flywheel, which is integrated with the transmission system. The flywheel plays a crucial role in maintaining smooth engine operation by storing rotational energy and assisting in the engagement and disengagement of the clutch, ultimately allowing for torque transfer to the wheels.

In contrast, the camshaft is responsible for controlling the opening and closing of the engine's valves and does not play a role in torque transfer. The oil pump is involved in circulating engine oil to lubricate moving parts, ensuring efficient operation of the engine, rather than transferring torque. The distributor, on the other hand, directs high-voltage electricity to the correct cylinder at the appropriate time for ignition and also does not function in torque transfer. Thus, the crankshaft is the correct choice for transferring torque to the transmission flywheel.
