DDifficulty 2/5

There is a flywheel at one end of the crankshaft. What is it used for?

Correct answer

To overcome the dead centres through which the pistons pass.

The flywheel stores rotational energy and helps carry crankshaft rotation between engine impulses, carrying the pistons through dead centres and smoothing speed fluctuations. It does not keep rpm exactly constant in every situation, and its function is not simply to increase or reduce engine speed.
