If the combustion chamber is already hot enough then it will supply the heat to the fuel and fuel will burn readily and that too before the spark and therefore a premature ingnition will take place. I think this is (premature ignition) what causes knocking in SI engines.

In CI engine knocking is caused by ignition delay, so an increase in wall temperature reduce knocking.

Then, What is for si engine?

Knocking will increase when in case IC engines, where as in CI engines knocking will decreases.
