Which effect increases when an internal combustion engine's fuel injectors deliver excessive fuel volumes under normal operating temperature?

💡 Explanation

When fuel injectors deliver excessive fuel, incomplete combustion occurs because the air-fuel ratio is too rich which leads to liquid fuel washing past the piston rings increasing the blow-by. Therefore, piston ring blow-by results, rather than element melting, bearing breakdown, or compressor fouling, caused by distinct problems.
