What does EGT mean?

• A. Exhaust Gas Temperature
• B. Engine Ground Test
• C. Electrical Ground Test
• D. Exhaust Gas Turbine

Answer: (A)

EGT stands for Exhaust Gas Temperature. It’s the temperature of the gases as they exit the engine, measured by sensors in the exhaust path. This value is a key indicator of how combustion is progressing and how the engine is performing. If the EGT is too high, it can signal a lean fuel mixture, timing issues, or misfiring, which can lead to overheating or engine damage. If it’s too low, it may indicate a rich mixture or sensor trouble, meaning combustion isn’t converting fuel into energy efficiently.

The other options describe different concepts that aren’t what EGT represents: a test named Engine Ground Test, a test named Electrical Ground Test, or a component name like Exhaust Gas Turbine.
