🔍 Key Concepts

• compression stroke and TDC (top dead center) in a diesel engine • how piston movement affects cylinder volume, pressure, and temperature • relationship between ignition timing and changes in cylinder conditions

💭 Think About

• Think about what happens to the piston position and cylinder space as the piston moves from just before TDC to exactly at TDC. • Which of the listed properties (temperature, volume, energy, pressure) is MOST directly tied to the piston’s position and how far the gas can expand or compress? • Right after ignition but before the piston reaches TDC, which property is LEAST likely to change significantly in that very short interval of movement?

✅ Before You Answer

• Clarify in your mind what TDC (top dead center) means for piston position and cylinder geometry. • Identify which option depends mainly on piston displacement and cylinder geometry rather than on combustion heat release. • Ask yourself: in the tiny crank-angle range just before TDC, which property of the gas is almost fixed by the mechanical design of the engine?
