Innovative solution for reducing fuel consumption of locomotives
German engineering company Voith has unveiled its innovative solution for diesel locomotives. It automatically switches off the traction engines during waiting periods. This allows the railway undertakings to reduce their costs by consuming less fuel.
The Voith-developed OnEfficiency.StopStart innovative technology is dedicated to waiting periods of locomotive work. Its key feature is to constantly monitor important status variables of the traction engine, automatically stop and restart it when a vehicle does not run. In this way, long set-up times are avoided and the vehicle is always ready for operation even in stop mode. The new stop-start technology from Voith is approved by the German Federal Railway Authority (EBA).
According to Voith, each locomotive works at idle on the line bottlenecks, during the train formation process and other operations. Totally, the vehicles spend more than 30 per cent of their operating time for waiting periods. This leads to inefficient consumption of diesel fuel. Voith estimates that its new solution reduces the idle time of a locomotive by an average of 720 hours per year, resulting in fuel savings of up to 11,000 litres.
“In addition, the number of refuelling stops as well as emissions are significantly reduced. Besides these advantages, the reduction in engine operating hours offers the possibility of extending the maintenance intervals depending on the operating hours, thus saving maintenance costs. By installing the OnEfficiency.StopStart system, locomotives can contribute to future-oriented and environmentally friendly rail transport,” the German company stated.
