What does the cylinder head temperature indication refer to?

  • A

    All cylinders.

  • B

    A random cylinder.

  • C

    The critical cylinder.

  • D

    The average of all cylinders.

In a piston engine, the Cylinder Head Temperature (CHT) gauge (which uses a thermocouple involving copper and constantin) shows the temperature of one selected cylinder (critical cylinder), which is not necessarily the one that reaches peak temperature first, even though it may end up as the hottest.

Therefore, the correct answer is "the critical cylinder."
