Variable Compression for Large Engine
- 230 Downloads
In order to meet future requirements in the marine sector, different technologies are needed. The most important technologies like two-stage charging, variable valve train, Miller timing and waste heat recovery are explained in the technical literature . The variable compression ratio is explained as follows in more detail.
Improving the Efficiency of Dual-fuel Engines
Global trade continues to rise steadily and continuously reaches new peak levels. This trend can be attributed in particular to container handling, which has increased by 20 % over the past six years . In the maritime sector, the regulations of the International Maritime Organization (IMO), which address the reduction of air pollutants from shipping as well as energy-efficiency of vessels, are driving the development of future propulsion systems. One pillar of these regulations was the introduction of so-called Emission Control Areas (ECA) in major coastal areas . The use of dual-fuel engines, capable of diesel...
