🔍 Key Concepts

• spark arrestor design in diesel exhaust systems • how mass and inertia of glowing carbon particles compare to exhaust gas flow • difference between changing flow direction and simply speeding it up or cooling it

💭 Think About

• Think about how you would physically separate heavier glowing particles from a fast-moving gas stream without adding water or refrigeration. • Which type of flow path would make the solid particles hit a surface and lose energy, while the gas continues on? • Do exhaust systems on small craft normally have equipment to cool exhaust significantly, or do they rely more on internal baffles and passages?

✅ Before You Answer

• Identify which option actually causes particles to impact internal surfaces and fall out of the gas stream. • Eliminate any choice that would mainly increase spark energy instead of removing it. • Ask which method is commonly used in simple, low-maintenance marine exhaust devices (no pumps, no coolant, no moving parts).
