Design Features

Nodular cast iron engine block and crankcase with integrated ducts for lubricating oil and charge air

Engine block with lucbricating oil supply to the crankshaft, camshaft control system and camshaft bearings through drilled ducts.

Simplified parts spectrum by using single-pipe exhaust gas ducting

Simplified parts spectrum by using single-pipe exhaust gas ducting

Low weight, low installation volume and low vibration level.

Cooling water system with simple plug-in connections

Easy to fit, very maintenance-friendly cooling water system with a reduced number of components/parts and increased operational safety.

Pulse charging system, available as an option, for all in-line engine variants

Pulse charging system with optimum engine acceleration and advantages in marine propulsion systems subject to frequent changes of load.

High-efficiency turbocharger

Corrosion-free turbocharger with low temperature level of components surrounding the combustion chamber.

Cylinder liner, only cooled outside the engine block

Long life cylinder liner with low wear rate due to calibration ring and low and constant lubricating oil consumption.

Engine control terminal with analog instrumentation in robust cast casing

Securely mounted engine control terminal with engine and turbocharger speed display.

Segmental camshaft design

Simple to assemble and dismantle camshaft with individual segments per cylinder.

Installation-friendly, because of pumps and filters installed on the engine

Lubricating oil automatic filter fitted to the engine.

Connecting rod, split off design

High level of operational safety, the result of accurately preloaded bolts.

Compact module for lower valve drives and injection pump drives with cam followers

Exact straight-line guidance for low-friction and low-wear operation.

Compact cylinder head design

Simple and fast assembly/dismantling of compact cylinder head design with long intervals between overhauls.
