What does an exhaust temperature gauge measure?

The temperature of the engine block

The temperature of exhaust gases

An exhaust temperature gauge specifically measures the temperature of the exhaust gases leaving the engine. This measurement is crucial for several reasons. It helps monitor the efficiency of the combustion process, as excessively high temperatures can indicate abnormal combustion conditions, such as overly lean mixtures or ignition timing issues. Keeping track of exhaust gas temperatures allows for proper adjustments to fuel mixtures and helps in detecting potential engine problems before they lead to failure. Monitoring the exhaust gas temperature is also essential in turbine engines, where it ensures the engine operates within safe thermal limits, thereby enhancing safety and longevity.

Understanding the temperature of exhaust gases is vital for maintaining optimal engine performance and ensuring compliance with environmental regulations related to emissions.
