Materials and process innovation for low-emission powertrains
From marine propulsion systems and locomotive engines to units for power generation, increasingly efficient and low-emission propulsion concepts are being adopted. Most of these technologies, which are still based on internal combustion engines, rely on alternative fuels – placing increased demands on combustion chamber components. M. Jürgensen develops new material solutions and machining options for the cylinder liners of such engines. Continue reading
The heavy-duty engine sector has been undergoing a paradigm shift for several years. Increasing efficiency requirements and stricter emission limits are driving the use of alternative fuels such as methanol, ammonia, or hydrogen. At the same time, engine manufacturers are constantly expected to optimize efficiency and boost the performance of their engines.
For manufacturers of combustion chamber and powertrain components, however, this often presents new challenges in materials engineering. Many alternative fuels and increasing performance requirements are altering the stresses on components. New chemical reaction conditions, different temperature ranges, and additional mechanical stresses are pushing proven standard materials to their limits.
As a leading manufacturer of cylinder liners for large engines, M. Jürgensen is working on high-performance and future-proof material and product solutions that are adapted to the changed conditions caused by alternative fuel types. Components made of Compact Graphite Iron (CGI) or with a nitrided surface, for example, demonstrate significant potential in practical applications. Their outstanding mechanical and thermal properties make them the ideal basis for highly stressed combustion chamber components such as cylinder liners.
However, the material alone is only part of the solution. What matters most is the ability to manufacture it consistently to the highest quality standards. This is where M. Jürgensen’s strength lies: by continuously refining its own production processes and collaborating closely with its customers, the company lays the groundwork for stable mass production.
In addition to material development for casting, the machining of components is also coming into focus. New specifications for the cylinder bore and its honing structure are gaining importance as key factors in specifically influencing, for example, friction, lubricant ingress into the combustion chamber, and fuel consumption – all of which contribute to the efficiency of modern engines.
Comprehensive material expertise and innovative process technology thus result in cylinder liners with high strength, excellent thermal conductivity, and improved tribological properties that fully meet the high demands of modern powertrain systems. This makes M. Jürgensen the ideal development partner and supplier, actively shaping engine design with future-proof solutions and contributing to decarbonization through modern powertrain systems.
