Overview
The acceptance of the M 32 C long-stroke engine series in the marine industry is a success story, whose equal is hard to find in this power class. Since its introduction in 1994, more than 1600 engines have been sold. 80% of them are marine propulsion engines, and 20% are electrical generator sets. The M 32 C series is a genuine heavy fuel engine, and 75% of all engines commissioned burn the economical heavy fuel oil. The M 32 C long-stroke series with a bore of 320 mm has continued the market success of its predecessor in this bore size. Decisive factors in its development have been maximum customer benefit requirements, i.e. economy and operational reliability. Environmental aspects, however, have also been important. Operational results have fully confirmed the design objectives.

Pulse charging system, available as an option, for all in-line engine variants
Advantages in marine propulsion systems subject to frequent changes of load, Optimum engine acceleration without special control system arrangements
High-efficiency turbocharger
Moderate temperature level of components surrounding the combustion chamber, Corrosion-free turbocharger casing without water cooling
Cylinder liner, only cooled outside the engine block
Low wear rate due to calibration ring, Low and constant lubricating oil consumption, Long life
Engine control terminal with analog instrumentation in robust cast casing
Securely mounted with vibration damping on the crankcase, Direct and reliable display of all operating media pressures by robust pressure gauges, Engine and turbocharger speed display by vibration-protected analog instruments
Segmental camshaft design
Individual segments per cylinder, Simple to assemble and dismantle
Installation-friendly, because of pumps and filters installed on the engine
Lubricating oil automatic filter fitted to the engine, Replaces duplex filter and separate automatic filters, Pumps and filters operate without any external power, Reduces the parts requirements
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
Long intervals between overhauls, Simple and fast assembly/ dismantling because of: - plug-in connections - integrated bores - self-centering
