The knocking tendency in spark ignition engines may be decreased by Correct Answer Reducing the compression ratio

The knocking tendency in spark ignition engines may be decreased by Reducing the compression ratio.-A lean mixture reduced the knocking tendency, allowing to operate the CFR engine at higher CCR. -The high concentration of nitrogen in the mixture increased the ignition delay time of the end gas, thus reducing the knocking tendency of the engine.
