Which outcome reduces volumetric efficiency from over-advanced fuel injection timing in a high-performance gasoline engine?

💡 Explanation

Over-advanced injection timing encourages end-gas autoignition that creates uncontrolled combustion, termed knocking detonation, because increasing cylinder pressure and temperature goes beyond fuel's self-ignition threshold without spark, therefore, inducing knock rather than smooth, controlled combustion.
