Which risk is amplified when an ICE compression ratio increases?

A)Increased fuel auto-ignition probability
B)Reduced exhaust NOx formation
C)Decreased cooling system efficiency
D)Lower indicated thermal efficiency

💡 Explanation

Increasing the compression ratio in an internal combustion engine raises the air temperature during compression; this raises the probability of auto-ignition because it exceeds auto-ignition temperature, therefore causing engine knocking, rather than achieving ideal combustion phasing.
