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.
