Poor Engine Start or Unstable Low Load Running
- Usually poor ignition quality of the fuel causes this. Check CCAI and if borderline raise scavenge air – coolant temperature as much as possible or change to marine Diesel oil to start up.
- Also check for correct injection viscosity which if incorrect can cause poor atomization and therefore late or no ignition at all.
- Poor / no start up also potentially caused up acidic / basic content in the fuel causing sticking – scuffing of plungers and valves in injection equipment.
