Future proof 49/60DF engine

The 49/60DF – future-proof in multiple ways

Best fuel costs and long-term emissions compliance with the 49/60DF engine 

The benchmark efficiency of the new 49/60DF marine engine (former MAN 49/60DF) and its outstanding fuel flexibility – enabling operation on LNG, diesel, or HFO – ensure the lowest possible fuel costs across all modes. 

Looking ahead, the high efficiency and low methane slip of the 49/60DF engine support compliance with emissions regulations well into the 2030s. Beyond that, the advanced dual fuel design and modern platform of the 49/60DF engine provide multiple technology pathways for emissions compliance through 2050 and beyond.

Engine overview 

The new 49/60DF is available as an in-line engine with 6, 7, 8, 9 or 10 cylinders or as a V-type engine with 12 or 14 cylinders. Its output ranges from 7,800 to 18,200 kW. 

It is available as a main engine for mechanical or electrical propulsion. Its high configuration flexibility makes it ideal for numerous applications such as cruise ships, RoPax, RoRos, dredgers and LNG carriers. The 49/60DF is based on a new 49/60 engine platform designed for a variety of applications and fuels. This modern engine platform introduces new technologies such as the Everllence Common Rail 2.2 injection system and two-stage turbocharging. 

Engine automation and control system

The 49/60DF features the SaCoS 5000 engine automation system. It is an evolution of the well-known SaCoS One system and has been developed by Everllence to offer the same outstanding reliability, proven robustness and comprehensive functionality. SaCoS 5000 comes with a performance upgrade in all components. With this latest generation of engine automation systems, the 49/60DF can comply with very high cybersecurity requirements. 
The Adaptive Combustion Control ACC 2.0 is one of the key enablers for improved efficiency and in-field performance. The 49/60DF adapts itself automatically to changing ambient conditions, varying fuel qualities, and engine wear thanks to ACC 2.0. With ACC 2.0 the 49/60DF achieves benchmark levels of dynamic engine operation, such that the vessel operates in gas mode even in challenging situations like manoeuvring.

Feasible decarbonization paths to 2050

Low methane slip and benchmark efficiency ensure vessels are emissions-compliant well into the 2030s, subject to possible changes in legislation. The 49/60DF was designed with future retrofits in mind.
  • Everllence is already working on retrofittable exhaust gas after treatment solutions
  • Natural gas can be replaced by biogas or synthetic natural gas, allowing vessels to be emission-compliant until 2050
  • Retrofit solutions for methanol are in planning
