• Engine Instruments – Cylinder Head Temperature

  • Measures the temperature at one or more of the cylinder heads, this is at the top of the cylinder.

  • This can be used to warn of over-heating, pre-ignition, and detonation.

  - Pre-ignition – ignition of fuel-air mixture prior to the spark plug firing.

  - Detonation – spontaneous combustion of the remaining fuel-air mixture in the chamber after normal combustion by the spark plugs.
