🔍 Key Concepts

• Carefully read the label on the gauge face that says DIESEL INDICATOR and think about what kind of measurements an indicator instrument is used for on a diesel engine • Recall the purpose of an engine indicator connected to the cylinder and how it relates to pressure changes during the cycle • Distinguish between devices that measure conditions in the cylinder and devices that act on the cylinder (like safety valves or injectors)

💭 Think About

• Which of the choices describes a function where you would need a dial gauge with a pressure scale up to very high values? • Which options involve actually changing cylinder conditions (adding fuel, removing moisture, relieving pressure) versus simply observing or recording them? • On a slow‑speed diesel, when would an engineer use an indicator like this—during normal operation, during starting, or during troubleshooting of power balance between cylinders?

✅ Before You Answer

• Verify which answer choice involves measuring cylinder pressure rather than changing it • Check whether a device that injects fuel or relieves pressure would normally have a large dial gauge like the one shown • Confirm that the word indicator usually refers to an instrument used to take readings (for example, pressure over the stroke) instead of a control or safety device
