What does the acronym EGT stand for in relation to engines?

The acronym EGT stands for Exhaust Gas Temperature, which is a critical measurement in engine performance and diagnostics. Monitoring EGT helps assess how well an engine is operating, particularly in relation to combustion efficiency and emissions. High EGT readings can indicate issues such as poor air-fuel ratios, excessive load, or malfunctioning turbochargers, which can lead to engine damage if not addressed promptly. Understanding EGT is essential for optimizing engine performance, ensuring fuel efficiency, and minimizing environmental impact through better emissions control. This measurement is particularly important in diesel engines, where maintaining the appropriate EGT can directly influence engine longevity and performance.
