Question 1 of 27070

Q

Large, two-stroke/cycle, main propulsion, diesel engine cylinders can be successfully pressure charged during normal operation by using the __________.

🔍 Key Concepts

• Scavenging and turbocharging methods used on large two-stroke main propulsion diesel engines • Difference between constant-pressure and pulse-pressure turbocharging in marine engines • Why two-stroke main engines need a pressure-charging system instead of relying only on natural aspiration

💭 Think About

• Think about how fresh air is supplied and exhaust is removed in a slow-speed, two-stroke marine engine. What role does the turbocharger play? • Which of these options actually describes a recognized type of turbocharging system used with large, low-speed marine diesels? • Eliminate any answer choices that sound like control/monitoring functions rather than a specific method of pressure charging air.

✅ Before You Answer

• Check which term(s) are commonly paired with turbocharger descriptions in marine engineering texts (e.g., types of turbocharging systems). • Verify whether each option describes a system for charging/scavenging air or something unrelated like temperature monitoring or load control. • Be sure the correct choice refers directly to a method of supplying high-pressure air to engine cylinders, not just measuring or managing exhaust gases.
