🔍 Key Concepts

• how compression pressure is created and what parts form the sealed combustion space in a diesel cylinder • differences between fuel‑system problems and compression‑pressure problems • mechanical clearances and wear that affect how much the air charge can be squeezed

💭 Think About

• Ask yourself which option directly reduces how much the trapped air can be squeezed in the cylinder before injection, even if the fuel system were perfect. • Decide which choices mainly affect fuel quantity or exhaust flow after combustion rather than the sealing and volume of the compression space. • Think about what happens if the piston does not come as close to the cylinder head as designed at top dead center (TDC). What does that do to compression?.

✅ Before You Answer

• Identify which answer changes the effective compression ratio by increasing the clearance volume above the piston. • Eliminate any options that only affect fuel delivery rate but do not change the trapped air’s compression. • Consider whether exhaust back pressure mainly influences scavenging and power output, or the actual compression pressure in the cylinder.
