Question 1 of 27070

One end of a cylinder for a medium or high-speed diesel engine is sealed by the piston and rings, the other end is sealed by the __________.

🔍 Key Concepts

• How a diesel engine cylinder is sealed to contain high compression • The names and locations of major engine components at the top and bottom of a cylinder • The difference between parts that actually close off the combustion space vs. external covers or supporting structures

💭 Think About

• Picture a single cylinder in cross-section: which part actually forms the closed space where air is compressed and fuel burns at the top? • Which listed parts are structural supports or covers, and which directly face the combustion gases? • Ask yourself: if I removed this part, would the combustion chamber be open and unable to hold compression?

✅ Before You Answer

• Identify which choice is directly bolted to the top of the cylinder liner and contains the intake and exhaust valves • Eliminate any parts that are mainly for support/structure and not for sealing combustion pressure • Verify which component normally houses the fuel injector and possibly the starting air valve on a medium or high-speed diesel
