Otto cycle is more efficient than the Diesel

Diesel cycle is more efficient′than Otto

both Otto and Diesel cycles are, equally efficient

compression ratio has nothing to do with efficiency

vaporisation

carburetion

ionisation

atomisation

peak pressure

rate of rise of pressure

rate of rise of temperature

peak temperature

All the irreversible engines have same efficiency

All the reversible engines have same efficiency

Both Rankine and Caront cycles have same efficiency between same temperature limits

All reversible engines working between same temperature limits have same-efficiency

Diesel cycle

Otto cycle

Dual combustion cycle

Special type of air cycle
