MAN B&W S50ME Typical Problems

1. 🔧 Unstable idle / RPM fluctuations

Causes:

Errors in fuel injection adjustment

Faulty Alpha (ELFI/ELVA) servomotors

Pressure in the control oil system is outside the normal range

Solution:

  • Check the calibration of the ME-Engine electronic control
  • Diagnose the injection system and valve operation

2. 💨 Increased smoke (white or blue smoke)

Causes:

Insufficient combustion chamber temperature

Problems with fuel supply (non-working injector)

Worn piston rings or valve guides

Solution:

  • Check injection time and volume
  • Diagnose injectors and cylinder tightness
  • Analysis of exhaust and temperatures by cylinders

3. ⚙️ Wear of cylinders and pistons

Causes:

Incorrect operation of the system cylinder lubrication

Using the wrong cylinder oil

Violation of temperature conditions

Solution:

  • Check the Cylinder Lubricator (Alpha Lubricator) supply
  • Select the correct viscosity and TBN of the oil
  • Conduct regular endoscope inspection of the cylinders

4. 🛢️ Problems with the lubrication system

Symptoms:

Loss of oil pressure

Dirty filters

Low level signals

Causes:

  • Worn oil pump
  • Leaks or internal clearances
  • Dirty oil separator or heat exchanger

5. 🧠 Electronic control system (ME) errors

Causes:

Failures of pressure, temperature, position sensors

CAN bus or controller (MCU, SFOC Module) failures

Poor contact or corrosion in connectors

DTC errors:

  • FIVA Position Sensor Fault
  • ELFI Position Deviation
  • Hydraulic Oil Pressure Low

Solution:

  • Diagnostics via ME-Visual or MAN CEON
  • Check all sensors and hydraulic control system

6. 🌀 Turbocharging malfunctions

Causes:

Turbocharger contamination

Valve control actuator malfunction

Exhaust gas flow malfunction (clogging)

Solution:

  • Cleaning turbine and pipelines
  • Check actuator and servo drives
  • Analysis of back pressure in the exhaust system
