🔍 Key Concepts

• How temperature of exhaust gas relates to how hard each cylinder is working • Common instruments used to measure exhaust gas conditions on multi-cylinder diesel engines • Practical methods an engineer can use routinely while the engine is running

💭 Think About

• Which of these choices is most practical for checking each cylinder’s performance several times a day at sea? • Which method gives you a quick numerical indication that one cylinder is running hotter or colder than the others? • Think about what kind of instrument is usually mounted on the exhaust manifold near each cylinder outlet.

✅ Before You Answer

• Identify which option is specifically associated with temperature indication of exhaust gas from each cylinder • Eliminate methods that would require complex lab equipment rather than engine-room tools • Focus on the method that provides immediate, on-the-spot comparison between cylinders while the engine is operating
