To Next PageTo Next PageWhat causes my Doosan 7/41 to have excessive white smoke?
Excessive white smoke from your Doosan Compressor can be caused by water mixing in the fuel, low compression pressure, incorrect injection timing, low coolant temperature, or a faulty turbocharger.
What causes low engine output in Doosan 7/41?
Low engine output in your Doosan Compressor can stem from several issues: incorrect injection pump adjustment (incorrect injection timing), injection nozzle malfunction (incorrect injection pressure), insufficient fuel supply to the injection pump (lack of fuel in tank), air in injection pump, a clogged fuel filter, overflow valve malfunction, or governor malfunction (incorrect engine control adjustment) or deteriorated governor spring. Check for incorrect injection timing, incorrect injection pressure, and lack of fuel in tank.
What causes unstable engine running in my Doosan 7/41 Compressor?
Unstable engine running in your Doosan Compressor can result from unstable low idling (possibly due to a crack in the injection pipe), injection nozzle failure, engine stop solenoid return failure, or uneven compression pressure between cylinders. Check for a crack in the injection pipe.
Why is my Doosan 7/41 engine burning oil?
If your Doosan Compressor engine is burning oil, it could be due to faulty piston rings or damaged cylinder bores, or a faulty valve stem seal.
What causes excessive fuel consumption in my Doosan Compressor?
Excessive fuel consumption in your Doosan Compressor can be caused by fuel leakage due to damaged seals, improper component installation or tightening, or excessive injection volume due to a defective injection pump. Check for damaged seals.
Why does my Doosan 7/41 engine not start?
Several factors can prevent your Doosan Compressor engine from starting: a discharged battery, bad cable connections, starter or starter switch failure, or a safety relay failure. Refer to Col4 for repair and diagnostic procedures.
