Which outcome is amplified when diesel engine fuel injectors deliver excessive fuel quantity?

💡 Explanation

When fuel injectors deliver excessive fuel, incomplete combustion occurs because of oxygen deficiency in combustion chamber, leading to increased emissions. Therefore, increased particulate matter and opacity results, rather than stability, pressure reduction or enhanced efficiency, all requiring more balanced air-fuel mixture.
