🔍 Key Concepts

• Compression ratio and how it affects peak pressure and temperature in a diesel engine • Relationship between compression ratio and thermal efficiency in internal combustion engines • Why diesel engines rely on high compression for ignition (no spark plug)

💭 Think About

• What happens to the air temperature in the cylinder when you compress it more (higher compression ratio)? • Does hotter, more compressed air generally make combustion more or less efficient in a diesel engine? • Is a diesel engine’s ability to convert heat to work helped or hurt by increasing compression ratio?

✅ Before You Answer

• Verify how thermal efficiency of an ideal diesel (or Otto) cycle changes as compression ratio increases • Check whether higher compression would logically speed up or slow down ignition and combustion in a compression-ignition engine • Confirm whether expansion ratio is directly tied to compression ratio in a fixed-stroke engine design
