🔍 Key Concepts

• Compression pressure depends on how much air actually gets into the cylinder and how well it is sealed during compression • Anything that restricts air flow into the cylinder can change the amount of air available for compression • Anything that allows air to leak out of the cylinder (valves, rings, seats, cages) will reduce the pressure reached at top dead center

💭 Think About

• For each choice, ask: does this problem prevent enough air from getting into the cylinder, or does it let compressed air escape during compression? • Think about where a valve cage and exhaust valves are located in relation to the combustion space—if they are damaged or leaking, what happens when the piston comes up on the compression stroke? • Consider whether a clogged air filter changes the cylinder’s maximum compression pressure, or mainly affects how much air the engine can draw in overall and thus its power output

✅ Before You Answer

• For each option, decide: does this fault directly reduce the sealed compression in the cylinder, or does it mainly affect breathing/efficiency? • Visualize the compression stroke with the intake and exhaust valves closed—which of these faults would still allow air to leak out past a closing surface? • Be sure you can explain in one sentence for each choice: how exactly would this change the measured compression pressure on a test gauge?
