Why Is My Diesel Engine Losing Power?
Power loss can result from restricted fuel filters, injector problems, turbocharger faults, or airflow restrictions. Some engines also reduce output when their control systems detect certain failures. Testing fuel pressure, airflow, and stored fault codes helps identify the cause without unnecessary component replacement.
What Causes A Diesel Engine To Knock?
Diesel knocking can result from abnormal combustion, incorrect injection timing, injector faults, or internal mechanical wear. A deep, persistent knock may indicate bearing damage. Because the causes vary widely, identify when the noise occurs and inspect the engine before deciding on repairs.
