Advanced Common Rail Injection for Medium Speed Engines
- 64 Downloads
Emissions regulations come in discrete packages enacted on a set date but engine development is a continuous process. Since IMO Tier II, engine builders and component suppliers have worked consistently to eliminate fuel consumption penalties on the first compliant engines and to reduce NOx emissions to the absolute minimum at source. At OMT the development focus is multi-shot fuel injection with heavy fuel oil from common rail systems where injection pressure is also freely selectable.
Combustion Process Optimisation
During the past decade, new technologies for large diesel engines in marine, power generation and railway applications have been mainly driven by environmental friendliness, especially in connection with heavy fuel oil (HFO). New emissions legislation requires considerable development efforts from engine designers and system suppliers to produce solutions which fulfil not only that aspect. At the same time traditional customer demands like high engine efficiency under all...
