Which risk increases when fluid exceeds the Reynolds number threshold in a fuel injection system?

💡 Explanation

Increased turbulence intensity enhances fuel-air mixing but it causes engine knocking because the **autoignition** limit is surpassed by greater premixing, therefore increased engine knocking takes place, rather than improved vaporization which might occur with less developed turbulence.
