Description
|
| |
|
|
|
|
Due to the long useful life of railway vehicles there are a lot of old diesel locomotives with a bad fuel economy in service. For old stock re-engining is a means to improve fuel economy and reduce exhaust emissions. With re-engining the existing diesel engine is replaced by a new one with better economic and environmental performance. In many cases, re-engining has to be performed in close co-operation with the original manufacturer since engine layout is often closely related to locomotive design. Therefore one engine cannot simply be replaced by another engine of the same power class. |
