It is much easier to detonate a mixture of air and fuel if it is highly compressed prior to (or during) the ignition process.

这是非常容易引爆的空气和燃料如果是高度压缩之前(或期间)点火过程的混合物。

The fast-ignition technique is more like a petrol engine: first the fuel is compressed and only then is it ignited by a second laser pulse acting as a spark plug that is fired through a hole in the pellet.

ECONOMIST: Nuclear fusion

Instead of sparking the ignition when the piston is close to top dead center (when the air is compressed), that spark occurs as the piston is pulling away, when the air pressure is at its most turbulent, creating much faster ignition and more power.
