MAN D2842 LE103 V12 diesel engine unit 900 hp (662 kW)
The MAN D2842LE103 is a 12-cylinder, V-shaped (90°) 4-stroke diesel engine unit with turbo and intercooler, which is characterised by high reliability and durability under continuous loads. The 21.93 L displacement, direct injection and EDC DC5 electronic control allow for 662 kW / 900 hp at 2100 rpm, while maintaining clean combustion and stable traction. This model is commonly used in industrial generators (1500/1800 rpm), high-power pumping stations, compressors, stationary equipment and marine solutions where gentle work, rigid design and reserve for overloads are required.
Main technical advantages
Configuration: V12, 90°, balanced travel and lower vibrations at high speeds.
Combustion: Direct Injection; Accurate injection timing ensures efficient combustion.
Turbine + intercooler: lower intake air temperature, higher density, better filling and power.
EDC DC5 Control: Precise injection phase, simpler cold start, more consistent power over the entire speed range.
Oil system: force feed, full-flow filtration with two paper elements – reliable protection against abrasion.
Cooling: liquid, optimum operating temperature of 90-95 °C – maintaining thermostability even in 24/7 mode.
Power: 662 kW / 900 hp @ 2100 rpm
Ignition order: 1-12-5-8-3-10-6-7-2-11-4-9
Valve spacing (cold): intake 0.50 mm, exhaust 0.60 mm
Valve phases: intake 24° before VDT / 36° after ADT; exhaust 63° before ADT / 27° after VDT
Nozzles: six-hole; Opening pressure 335±8 bar (new) / 320±8 bar (use)
Injection start: 7°-1° vs. VDT
Oil volumes: in the crankcase min. 24 l / max. 32 l; Replacement quantity with filter ~35 l
Electrical equipment: starter 24 V, 9 kW; generator 28 V, 140 A

Operational recommendations
To maintain maximum reliability, it is necessary to use oil of the correct viscosity according to the operating temperature, change the filters according to the schedule and monitor the oil pressure according to the devices. Observe valve gaps and nozzle pressure norms – power, smoke and consumption directly depend on this. It is recommended to periodically perform diagnostics of the EDC DC5, synchronize the injection time, and check the sensors. Before a long-term “cold” start, it is useful to use a suitable fuel conditioner and take care of the cleanliness of the cooling system.
