🔍 Key Concepts

• Air intake sources for diesel engines and why location matters • Behavior of flammable vapors when drawn into an engine air intake • How a diesel engine responds to uncontrolled fuel sources (like vapors or oil mist) entering the intake

💭 Think About

• Think about what happens if a diesel engine breathes in a large quantity of combustible vapor along with its normal intake air. • Consider whether this situation is more likely to affect metal corrosion, engine power output, or engine speed control. • Ask yourself: which of the listed consequences would be immediate and dangerous enough that regulations and good practice specifically warn against it?

✅ Before You Answer

• Verify what actually causes turbocharger corrosion and whether flammable vapors in air are a primary factor. • Recall how a diesel engine can run away (over speed) when it ingests combustible vapors or mist that bypass the normal fuel system. • Consider whether drawing in flammable vapor would realistically create a safe, controlled increase in brake horsepower, or an unsafe, uncontrolled condition.
