Which risk increases when internal combustion engines experience pre-ignition?

💡 Explanation

Pre-ignition causes engine knock because uncontrolled combustion creates extreme pressure spikes; this is a form of detonation. The rapid rise in cylinder pressure damages components; therefore, knock will cause ongoing catastrophic damage, rather than other fuel-related or volumetric issues.
