What makes the modern MaK diesel engine the responsible choice for clean shipping?
Its Selective Catalytic Reduction (SCR) system. SCR technology significantly reduces NOx emissions to meet IMO Tier III standards without affecting engine performance, reliability or efficiency in any way. In fact, fuel economy remains high, noise is reduced, and maintenance and installation on board are easy.
Learn more about how the MaK SCR system works and how you benefit in our SCR Brochure.
