Common question: "If you reduce the impeller diameter of a centrifugal pump by 10%, what happens to the flow and head?"

The correct answer is b . Black smoke indicates incomplete combustion (lack of air). If the turbocharger is fine (normal speed), the restriction is likely in the scavenge system. Clogged scavenge ports prevent fresh air from entering the cylinder, causing rich combustion. If the turbocharger is fine (normal speed), the
