Too Afraid to Ask

Cylinder pressure is how much “push” happens inside the engine’s combustion chamber when it burns fuel. Higher cylinder pressure usually means the engine is working harder.

Technical Definition

Cylinder pressure is the pressure inside each engine cylinder during the combustion cycle. It’s a key indicator of how hard the engine is working, and the speaker argues that cylinder pressure (rather than where/when it occurs) is what matters for making power and for break-in behavior.
