Petrol engine, used fixed octane rating fuel-if engine speed increases then knocking tendency decreases. And if comp.ratio increases then knocking tendency increases.

How can you please specify further?

As speed increases then delay decreases. So, knocking should increase.

As delay decreases knocking would decrease in SI engine vice versa in CI engine.

I think when speed increases more fuel is required, so unburnt fuel is less, decrease knocking tendency.

As the engine speed increases there will be more good combustion of fuel. So there Will be less unburnt fuel that leads to less knocking.

At higher speed more turbulence will generate in engine and knocking tendency will be reduced.
