Emission reduction technology is since 2000 an important pillar in the development strategy of MaK. This resulted in a Low Emission Engine (LEE) concept. The used technologies, for instance miller cycle, has been developed to optimize engine performance and lower NOx, CO2 and soot emissions.
One of the techniques used in the LEE concept is the adjustable camshaft or Flex Cam Technology (FCT). More information can be seen in this video:
The current MaK C engine types meet the IMO II standards.
