🔍 Key Concepts

• Air box fires in two-stroke diesel engines and what normally burns in that space • Typical residue left after a crankcase or scavenge/air box fire • Relationship between complete combustion, incomplete combustion, and the color/type of deposits

💭 Think About

• Think about what is actually inside an air box on a two-stroke main engine: is it usually clean air, oil mist, unburned fuel, carbon, or something else? • If those materials catch fire, will they burn completely to a light-colored ash, or will they tend to leave darker, carbon-rich deposits? • Which of these choices would most clearly show that there HAS been a fire, versus just poor maintenance, normal operation, or cleaning?

✅ Before You Answer

• Consider what color and texture of residue is normally associated with burnt oil and carbon in diesel engine spaces. • Ask yourself which option would be unlikely if high heat and burning had actually occurred. • Verify which answer choice best reflects a clear result of combustion, not just contamination or the absence of it.
