Design Features
Cylinder head
Increased reliability due to integrated media ducts.
Connecting rod
Split shaft for simple, rapid and error-free dismantling.
Piston crown
Forged piston crown with only three piston rings for high igni tion pressure strength and long life.
Cylinder head
Complex component in nodular cast iron, stiffness from twin-bottom design.
Cylinder liner with calibration ring
Robust cylinder liner protected from wear that has longer oil change intervals thanks to reduced dirt intake.
Turbocharger
Turbocharger with sliding bearings, no water cooling, connected to the lubricating oil circuit, service-friendly.
Engine block
Firm base for main and camshaft bearings due to inherent rigidity.
Multifunctional cooling water ring
Cooling water ring catering action during assembly of cylinder liner and head and protects cylinder head bolts from corrosion.
Valve Drive
Compact, modular design facilitates maintenance work on the camshaft bearings.
Crankshaft
New MaK bearing shell technology ensures a high level of operational reliability.
Injection pump
Optimum fuel injection into the combustion chamber and, in consequence, high efficiency.
Flywheel
The flywheel hub is shrunk onto the crankshaft by means of an oil shrink type connection.
Camshaft
The camshaft is, as built, equipped with vibration dampers.
Turbocharger connection
The V-position of the turbocharger permits optimum air induction and minimum center distance in the case of multi-engine installations.
Large inspection hatches
Large inspection hatches ensure satis factory access to the engine and camshaft areas.
Exhaust pipe cladding
The cladding is subdivided into segments and can be easily and rapidly removed and installed.
Exhaust gas system
Single pipe exhaust gas system with gas outlets and cross-sections optimized for efficiency on each cylinder bankspection of the bearings.
Gearwheel drive
The symmetrical arrangement of the gearwheels relative to one another permits, by exchanging the intermediate wheel and the stepped wheel, the use of the same camshafts in the case of different engine rotational directions.
Engine room monitoring
Oil mist detector in proven technology.
Terminal board
A terminal board for monitoring and inspection connections with plenty of space for cable connections when alongside.
Complete engine
The engine is on offer with a standardized pump and filter attachment.
Turning device
Fastened directly to the engine block in a safe and low vibration manner.
Exhaust ducting connections
Vertical exhaust outlets for simple connection to the exhaust gas system.
