<p>Engine builders MTU Friedrichshafen say that they have developed the cleanest locomotive diesel engine yet. </p> <p>The emissions of oxides of nitrogen from the 8V 4000 engine have been cut to below eight grams per kilowatt hour during recent test bed runs. </p> <p>The company said this means that the engine will meet UIC 1 standards now in force, as well as the UIC 2 standards which come into force in 2008. It may also be able to meet the follow-up standard UIC 3.</p> <p>Deutsche Bahn is using the MTU 8V 4000 unit to re-engine 400 of its V290 multi-purpose locos, as well as the remote controlled V294 used by DB Cargo for large-scale shunting operations around Germany.</p> <br />
