In a closed Diesel engine which condition results from uncontrolled autoignition?

💡 Explanation

Uncontrolled autoignition leads to engine knocking via rapid, uneven combustion. This occurs through compression ignition surpassing fuel's autoignition temperature, because the Cetane number is too low, therefore increasing pressure shock rather than controlled burning.
