🔍 Key Concepts

• How diesel mechanics typically compare temperature between cylinders during normal operation • What kind of instrument is commonly installed on the exhaust manifold of large marine diesels • Difference between checking gas composition vs checking heat/temperature

💭 Think About

• Ask yourself: For day‑to‑day engine watchstanding, which of these methods is practical to use quickly on all cylinders while underway? • Which option describes a simple, rugged device that can be permanently mounted and read at a glance by the engineer? • Which options would usually be used only in a lab or detailed troubleshooting, not as a routine performance indicator for each cylinder?

✅ Before You Answer

• Identify which choice is specifically related to measuring exhaust temperature • Eliminate any methods that require complex sampling or laboratory-style equipment • Think about what is typically found on the engine room gauge board or exhaust manifold for each cylinder
