The temperature measuring device in a four-cylinder in-line engine is typically fitted to which cylinder?

• A. 1
• B. 2
• C. 3
• D. 4

Answer: (D)

In a four-cylinder in-line engine, the temperature measuring device is typically installed in the last cylinder, which is often the fourth cylinder. This cylinder usually experiences the highest temperatures due to its position furthest from the cooling source, allowing for better monitoring of the engine's thermal performance and potential overheating issues. Positioning the temperature sensor in the fourth cylinder helps ensure that the most extreme operating conditions are accurately represented, enabling timely adjustments or maintenance if temperatures rise beyond acceptable limits. Using data from this cylinder can provide crucial information for ensuring the longevity and efficiency of the engine, making it a standard practice in engine design and monitoring systems.
