Advanced Common Rail Injection for Medium Speed Engines

Authors: Klaus M. Heim, Dr. Marco Coppo

Published in: MTZ industrial | Issue 2/2013

Excerpt

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. …
