Question 1 of 27070

Which of the following procedures should be carried out when a large, low-speed, diesel engine is operated with one cylinder secured?

🔍 Key Concepts

• Effect of securing (deactivating) one cylinder on a large low-speed diesel engine’s power balance • Relationship between engine power, turbocharger speed/air supply, and safe operating limits • Why overall engine loading and speed must match the number of firing cylinders

💭 Think About

• If one cylinder is not firing, what happens to total available power and how should the operator compensate? • How does running at the same speed with fewer working cylinders affect stresses on the remaining cylinders and the turbocharger? • Which action best protects the engine from overload or abnormal operating conditions when a cylinder is secured?

✅ Before You Answer

• Compare which options increase vs. decrease engine load and stress with one cylinder out of service • Think about what happens to turbocharger performance and air supply if power is not adjusted after securing a cylinder • Ask: which option would be a standard derating practice when running an engine on fewer cylinders?
