🔍 Key Concepts

• Ash content in heavy fuel oil and what it represents • Effect of abrasive contaminants (like ash) on engine components • Relationship between fuel quality and wear in combustion/exhaust spaces vs. bearings/liners/MEP

💭 Think About

• Which engine parts are directly exposed to the combustion products and solid particles in the exhaust gas stream? • Would an increase in non-combustible, abrasive particles be more likely to polish/smooth surfaces, erode them, or increase pressure produced by combustion? • Think about where ash deposits and hot, dirty gas flow are most concentrated along the engine gas path.

✅ Before You Answer

• Identify which option involves components that are directly in the path of hot combustion gases and ash-laden exhaust. • Decide whether increased ash would realistically raise mean effective pressure (MEP) or instead increase wear or deposits. • Consider whether bearing wear and liner glazing are typically caused by lack of lubrication/over-lubrication vs. hard abrasive particles in the fuel.
