Throughout the seagoing world, high-performance four-stroke diesel engines bear the name “MAN Energy Solutions”. As one of the world’s leading manufacturers, we offer engines and complete propulsion and power systems that are optimized for the most widely diverse marine applications. With mature and reliable technologies, our four-stroke engines play a leading role on the market. Longevity, efficiency, flexibility and environmental friendliness are their strengths, with power ranging from 1,000 to 22,000 kW. MAN Diesel & Turbo delivers uncompromising quality and trailblazing technologies in every detail.

Ecology meets economy: At the forefront of technological development

More than ever, our development focus is the environmental performance of our engines. The goal is to achieve uncompromising harmony between ecology and economy. Using our unrivalled grasp of large engine technology, we aim to make our engines progressively cleaner, more powerful and more efficient. We are firmly committed to reducing emissions while increasing fuel efficiency and power density. For our customers, it means engines and system packages that result in powerful yet clean prime movers.

Meeting emission stages

In recent years, global and local regulations covering exhaust gas emissions from heavy duty medium speed diesel engines have become progressively more stringent. In the case of large marine engines, they concentrate on limiting emissions of oxides of nitrogen (NOx) and the sulphur content in the fuel. Most recently, emissions of the greenhouse gas carbon dioxide (CO2) have also come under scrutiny. Our technologies for efficiency and ecology enable us to provide medium speed engines which comply with the most stringent emission limits.

The right choice: MAN Energy Solutions’s overall system competence

All core-technologies and core-competences in-house:

• Injection systems
• Turbocharger
• SaCoSone (Engine Control System)
• After Treatment Systems

We offer to design and execute highly efficient emission reduction packages for both new building and retrofits upon demand. This makes us an easy choice for Marine industry leaders who know that the key to successful investments and intelligent decision-making is choosing the right solution provider.
