Question 1 of 27070

An indicator card or pressure-volume diagram shows graphically the __________.

🔍 Key Concepts

• indicator card / PV diagram purpose in engine diagnostics • Difference between pressure vs. temperature and pressure vs. volume relationships • Meaning of stroke vs. cycle in a reciprocating engine

💭 Think About

• Ask yourself: What two variables are actually plotted on a standard indicator (engine) diagram used by marine engineers? • Think about whether an indicator card represents a full series of events (intake, compression, power, exhaust) or just a single motion of the piston. • Consider which option best matches how engineers use this diagram to assess engine performance and indicated power.

✅ Before You Answer

• Verify which pair of quantities are on the axes of a typical engine indicator diagram. • Confirm the difference between an engine stroke and an engine cycle for 2-stroke vs 4-stroke engines. • Eliminate any options that mention a quantity that is not normally plotted on an indicator card.
