Which risk increases when an Otto cycle engine operates with high intake air temperature?

💡 Explanation

High intake air temperature causes premature fuel-air mixture auto-ignition via thermal runaway; this is because of uncontrolled rapid oxidation prior to spark ignition, therefore engine knocking risk elevates, rather than optimized combustion.
