Lower operating costs and higher life cycle profitability

The MAN 45/60CR engine enables owners and operators to comply with ever more stringent emissions regulations and optimize their operating expenses at the same time. Our new engine provides unrivaled levels of low fuel consumption, driving down operating costs. By increasing standardization and using modular sub components, the new MAN 45/60CR engine also allows faster installation and easier maintenance. 

  • Highest power output in its class      
    1,300 kw per cylinder     
  • Lowest SFOC in its class
    Just 166 g/kWh
  • Matching a wide range of load profiles
    Common Rail Injection System with ECOMAP 2.0
  • Extended use of exhaust gas after-treatment (EGA) systems      
    High permissible backpressure
  • Improved use of heat      
    Optimized high-temperature cooling and lubrication circuits 

Environmental friendliness

Designed for a cleaner world

The MAN 45/60CR complies with the most demanding NOX regulations in combination with the compact MAN SCR (Selective Catalytic Reduction) exhaust gas aftertreatment system. Together with the innovative MAN ECOMAP function, it offers a whole new dimension in efficiency levels under different vessel operating profiles. The MAN 45/60CR will be a major contribution to achieving the stringent Energy Efficiency Design Indices (EEDI) of the future.

MAN has developed a whole range of systems that work together to safeguard the environment while maintaining the ship’s efficiency. Technologies such as MAN’s Common Rail Injection System improve a ship’s fuel economy, so it needs less fuel, produces fewer emissions and complies with EEDI guidelines.


Versatility at work

The new MAN 45/60CR engine is suitable for use in a wide range of marine applications. Its primary focus is reliable power generation, performance flexibility and superior efficiency in either diesel-electric or diesel-mechanical configurations. High-quality key components, modularized sub-designs and easy-to-install interfaces, make the engine a multitalented performer in many fields of application.

  • On a cruise vessel, you benefit from low emissions, low noise and high efficiency, thanks to its unrivaled flexibility.
  • On a ferry, it provides best in class efficiency with its two-stage turbocharger and meets tier three regulations with Selective Catalytic Reduction.
  • For dredgers, if offers a broad performance map with high dynamic operation capability and load acceptance.
