Due to the long lifetime of railway vehicles there is a large number of old diesel locomotives in service with a fuel economy far away from state-of-the-art technology. These engines can be upgraded in order to improve injection and compression characteristics.

Description
|
|
|
|
|
|
Railway vehicles, especially locomotives, have a long useful life (50 years and more). Therefore there is a large number of old diesel locomotives in service having a fuel economy far away from state-of-the-art technology. They can be upgraded in order to improve injection and compression characteristics.
Various modifications and conversion measures such as exhaust gas recirculation or modification of the injection system are viable. Most of these measures primarily aim at emission control. |
