🔍 Key Concepts

• Trend analysis depends on comparing data over time • Engine load and speed strongly affect temperatures, pressures, and fuel rates • For good diagnostics, you want comparable conditions from one reading to the next

💭 Think About

• If you want to detect a small change in engine performance, do you want the operating conditions to be changing a lot or staying similar? Why? • How would variable vs. stable load and speed affect your ability to tell whether a change is caused by the engine itself or just by different operating conditions? • Think about taking someone’s temperature: would you change the thermometer and the location each time, or keep the conditions the same to spot a fever? Apply that logic to engine data.

✅ Before You Answer

• Which choice best supports consistent comparison over time? • Which option would make it hardest to tell what changes are due to engine condition versus operating conditions? Eliminate that. • Focus on the answer that emphasizes similar or controlled load and speed conditions for each data point.
