Excessive oil consumption in your Doosan Compressor can be due to incorrect oil (wrong selection of type and viscosity) or too much oil quantity. Ensure the correct type and viscosity of oil are used.
What causes my Doosan Compressor engine to overheat?
Engine overheating in your Doosan Compressor may be due to a cooling system defect, such as insufficient coolant volume, fan belt slippage, thermostat malfunction, radiator filler cap malfunction, a fouled cooling system interior, or a clogged radiator. Check for insufficient coolant volume.
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 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 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.
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 fuel is injected but engine does not fire in Doosan 7/41?
If fuel is injected but the engine does not fire in your Doosan Compressor, it might be due to incorrect preheating operation, a faulty air heater, incorrect injection timing, low cylinder compression pressure, or the engine stop solenoid not fully returned.
What causes low cylinder compression pressure in my Doosan 7/41?
Low cylinder compression pressure in your Doosan Compressor can be caused by cylinder compression leakage (incorrect valve clearance adjustment), injector nozzle misalignment, or cylinder bore wear. Check for incorrect valve clearance adjustment.
What causes my Doosan Compressor engine to malfunction in high speed range?
Engine malfunction in the high speed range of your Doosan Compressor can be caused by insufficient fuel supply (air in the fuel system), a clogged fuel filter element, piping failure (squeezed/restricted), uneven fuel injection amount between cylinders, deteriorated governor spring, incorrect valve clearance adjustment, or a deteriorated valve spring. Check for air in the fuel system.
What causes insufficient air intake volume in my Doosan Compressor?
Insufficient air intake volume in your Doosan Compressor can be attributed to a clogged air cleaner or restricted air flow.
