New | M 20 C Marine Propulsion Engine

Developed and designed in response to special requirements of marine applications, the M 20 C is characterized by high reliability and economy. These features help to explain the continued high market demand for the M 20 C. The long-stroke design principle is the backbone of an excellent combustion process with low fuel and lubricating oil consumption, as well as low NOx emission. The M 20 C engine is SOLAS compliant. Its intelligent simplicity means high functional integration of fewer components. Fewer components mean greater reliability and easier maintenance. Overall, this leads to outstandingly low operating costs and rapid returns on investment. Reliability and ease of maintenance are convincing arguments in favor of the engines of this series.

The M 20 C Is An Engine With A High Safety Level. This Applies Not Only To Those Special Internal Design Features Which Guarantee Long Component Life And High Availability But Also To Safety In The Area Around The Engine. As A Result, Solas Regulations Are Strictly And Consistently Observed. Explosion Protection Cover For The Cylinder/crankcase Housing And Cladding Of The Complete Fuel And Exhaust Gas System In Stainless Steel Are Part Of An Overall Solas Safety Concept.

Long Maintenance Intervals And The Life Of Components Are The Basis For Low Operating Costs.

The Engine Is Marketed With A Standardized Range Of Installed Pumps And Filters. Inter Faces For Fuel, Lubricating Oil And Cooling Water Systems Are Located At The Opposite End To The Crankshaft Coupling For Ease Of Connection.

The Complete Diesel Generating Set Is Notable For Its Ease Of Installation, Reliable Operation, Ease Of Maintenance And Good Component Accessibility. The Basis Is Formed By The Rigid Base Frame As Foundation Of The Engine And Alternator With Integrated Oil Sump, Large Oil Volume And Universal Equipment For Both Hfo And Mdo Operation.
