← ScienceIn a closed Diesel engine which condition results from uncontrolled autoignition?
A)Increased knocking and piston damage✓
B)Improved fuel combustion efficiency
C)Lower exhaust NOX gas emissions
D)Reduced thermal stress on valves
💡 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.
