11 Air intake (x4)
Design
Water-cooled V12 Diesel engine with common rail (CR), exhaust gas turbo charging and air to
water charge air cooling.
Characteristics
A robust basic design and generous dimensioning form the basis for high operational safety and a
long service life. Low fuel consumption and exhaust gas emissions by optimized combustion
process adapted to the emission requirements. Minimized maintenance obtained by optimized
engine components and accessories lead to higher availability and increased efficiency.
Driving gear
The V12 Diesel engine has a quench tempered steel crankshaft with inductively hardened pins and
fillets. A torsional vibration damper is mounted on the crankshaft on the engine damper side.
Precisely forged con-rod, driving gear bearings are sputtered. Steel top weld pistons with stage
support and cooling duct
Housing
Rigid, laterally drawn down crankcase upper section with optimized structure and an oil pan as
lower section. Four–valve single cylinder heads with flow optimized ports as well as replaceable
valve seats and valve guide. Brackets, flywheel housing, aggregate support and oil pan on the
bottom close the Diesel engine.
Drive control
Two inlet and outlet valves mounted in the cylinder head for each cylinder. Actu-ated through steel
camshaft via cam follower, push rod and rocker arm.
Driven by gears on the flywheel side:
– Camshaft
– High pressure pump
– Fuel pre-feed pump
– Oil pump
Driven by gear train on the damper side:
– Water pumps
– Battery charging alternator
Lubrication
Force-feed lubrication with lubricating oil pump for crankshaft bearing, con-rod bearing and
camshaft bearing as well as piston pin bushings, cam followers, rocker arms and gear bearings.
Oil filtration depending on requirements such as automatic oil filter with centrifugal filter (optional).
Following auxiliary units are also connected to the Diesel engine — lubricant oil circuit:
– High pressure pumps
– Coolant pumps
– Turbochargers
– Air compressor (depending on machinery)
