Eli5:how car engine transform gas energy to the energy make wheels roll?

In: Engineering

Answer 1

When the gas in the engine explodes it pushes a piston down. The piston that moves down has a handle on it, and the handle is on a hinge, that allows the handle to wobble. The end of the wobbly handle is attached to a rod that is zig-zagged like a lightning bolt. So, when the piston pushes the wobbly handle, and the wobbly handle pushes on a zig-zag, the rod starts spinning. (There are usually 4 or more pistons and handles attached to the zig-zag rod)

That spinning rod is attached to your axle by gears, and the wheels are on the end of the axle.
