Clogged diesel engine fuel oil filters can cause __________,
• diesel fuel injection system operation and pressure requirements • effects of restricted fuel flow on engine performance • relationship between fuel filter clogging and cylinder combustion
• What happens to fuel flow and fuel pressure upstream and downstream of a clogged filter? • How would reduced or uneven fuel delivery affect how smoothly each cylinder fires? • If the engine is starved for fuel, which performance symptoms could appear at the same time?
• Verify how a restriction in the fuel line affects system pressure and volume to the injectors. • Consider whether loss of power, misfiring, and low fuel oil pressure could all logically result from the same cause. • Check if any one symptom can occur alone, or if multiple common symptoms are typically associated with clogged filters.
