Possible Causes

Faulty glow plugs on the SDMO diesel engine, Low compression due to engine wear, Water contamination in fuel, Incorrect injection timing

How to Fix / Troubleshooting

Safety first: Run the generator in a ventilated area. Avoid prolonged operation with severe misfiring.

  • Check glow plug operation: Verify the preheat indicator on the SDMO controller and test the glow plugs and relay as described in glow plug fault procedures.
  • Inspect fuel quality: Drain water from fuel filters and water separators. Replace the filters and refill with clean fuel.
  • Warm-up period: Allow the engine to warm up at no load for several minutes before applying load to reduce white smoke.
  • Seek engine specialist: Persistent white smoke with oil consumption may indicate internal engine wear or head gasket issues requiring professional repair.
