🔍 Key Concepts

• Thermal efficiency differences between low-speed two-stroke marine diesel engines and recuperated gas turbines • Relationship between fuel consumption and engine efficiency for a given power output • Typical exhaust characteristics (particulates and NOx) of large marine diesels versus gas turbines

💭 Think About

• For the same power, which type of engine is generally more fuel-efficient in large ocean-going ships: a slow-speed two-stroke diesel or a gas turbine, even with a recuperator? • Which kind of engine exhaust tends to have more visible smoke/soot (particulates), and which tends to have cleaner-looking exhaust but higher temperature? • How do high combustion temperatures and pressures typically affect NOx formation in diesel engines compared with gas turbines?

✅ Before You Answer

• Be clear which option pairs less fuel with higher emissions, and which pairs more fuel with lower emissions • Check that your choice matches what you know about modern slow-speed marine diesel efficiency vs gas turbine efficiency at ship-service loads • Verify that the statement about particulates and NOx trends (diesel vs gas turbine) matches general real-world behavior, not just what sounds environmentally friendly

Question 1 of 20

For the same amount of available power, how does a low-speed two-stroke diesel engine compare to a recuperated gas turbine configuration?

The two-stroke diesel engine would burn more fuel than a recuperated gas turbine; however, the particulate and nitrogen oxide (NOx) levels in the exhaust would be lower.

The two-stroke diesel engine would burn less fuel than a recuperated gas turbine; however, the levels of particulate and nitrogen oxide (NOx) levels in the exhaust would be higher.

The two-stroke diesel engine would burn more fuel and the particulate and nitrogen oxide (NOx) levels in the exhaust would be higher than that of a recuperated gas turbine configuration

The two-stroke diesel engine would burn less fuel and the nitrogen oxide (NOx) levels in the exhaust would be much lower than that of a recuperated gas turbine configuration.
