Which consequence results when biofuel contaminants lower cetane number?

💡 Explanation

Increased pre-ignition engine knocking occurs, indicated by a ‘pinging’ sound, because a low cetane number causes autoignition via compression heating, rather than controlled combustion. Therefore, engine knock increases, rather than decreasing efficiency at steady operation.
