Developed and designed in response to the special requirementsof marine applications, the most striking features of this engineare its high reliability and economy. These features help to explain the continued high market demand for the M 20 C as anengine for both marine propulsion and marine generating sets. The long-stroke design principle is the backbone of an excellentcombustion process with low fuel and lube oil consumption, as well low NOx emission. The M 20 C engine is SOLAS compliant.Its intelligent simplicity means the high functional integration offewer components. Fewer components mean greater reliabilityand easier maintenance.Overall, this leads to outstandingly low operating costs and rapidreturns on investment. Reliability and ease of maintenance areconvincing arguments in favour of the engines of this series.

Engine with high safety level

The M 20 C is an engine with a high safety level. This applies not only to thosespecial internal design features whichguarantee long component life and highavailability but also to safety in the areaaround the engine. As a result, SOLASregulations are strictly and consistentlyobserved. Explosion protection cover for the cylinder/crankcase housing and cladding of the complete fuel and exhaust gas system in stainless steel arepart of an overall SOLAS safety concept.

HFO/MDO – Long TBO and lifetime

Long maintenance intervals and the life of components are the basis for low operating costs.

Complete engine

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.

Reliable energy supply

The complete diesel generating set is notable for its ease of installation, reliableoperation, ease of maintenance and good component accessibility. The basis isformed 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 andMDO operation.
