Engines
The engines D 2866 E / TE / LE / LXE are in-line vertical liquid-cooled 6-cylinder four-
stroke Diesel engines with direct injection. D 2866 E is a naturally aspirated engine.
D 2866 TE is turbocharged, and D 2866 LE / LXE are turbocharged and intercooled.
Engine block
The cylinder block is a single piece of alloy cast iron. To increase its stiffness, it is ex-
tended to a level below the crankshaft centre line. The engine has replaceable wet cylin-
der liners and individual cylinder heads with shrunk-in valve seat rings and replaceable
valve guides.
Piston / Conrod / Crank assembly
The forged crankshaft has screwed-on counterweights. Radial seals with replaceable
wearing rings on crankshaft and flywheel are provided to seal the crankcase penetra-
tions.
The connecting rods are die-forged, diagonally split and can be removed through the top
of the cylinders together with the pistons. Crankshaft and connecting rods run in steel-
backed lead bronze ready-to-fit type bearings.
