Question 1 of 27070

A supercharged diesel engine, when compared to a similar naturally aspirated diesel engine, will develop an increase in __________.

🔍 Key Concepts

• supercharging and how it affects air density and mass of air in the cylinder • relationship between air quantity, fuel quantity, and power output in diesel engines • difference between brake horsepower, ignition lag, and specific fuel consumption

💭 Think About

• Ask yourself: When you force more air into a diesel cylinder, what does that allow you to do with the fuel, and how does that affect power? • Think about whether supercharging directly changes oil system pressure, or if that is controlled by a separate system. • Consider: If an engine is more efficient, what should happen to its specific fuel consumption—go up or down?

✅ Before You Answer

• Identify which option is most directly linked to increased air charge and fuel burning per cycle. • Eliminate any choices that are primarily controlled by separate systems (like lube oil pumps and pressure regulators). • Decide whether supercharging would logically make the engine use more fuel per unit power or less fuel per unit power.
