Diesel Engines

Convincing Performance from Every Cylinder.

Diesel Engines. Offering More Power than Ever Before.

The diesel engines developed specifically for rail vehicles are economical, rugged and durable. While at the same time minimizing noise and pollutant emissions!



V8 diesel engine
for railcars, special vehicles, light locomotives in single-engine applications and for locomotives in higher performance classes in multi-engine applications

The compact performance class: This V8 diesel engine features two-stage exhaust gas turbocharging, cooled exhaust gas recirculation and a maintenance-free catalytic converter for particulates. It is below the emission level Stage IIIB of the EU-non-road-directive 97/68/EC-2011/88/EC in effect since 2012. With a rated output of 500 kW, a maximum torque of 2,750 Nm and a displacement of 16.2 liters, this engine is suitable for motorization and remotorization of railcars, locomotives and special vehicles. An especially practical feature: no other fluid is necessary. This diesel engine is compact and can be incorporated easily. It offers convincing performance with minimal fuel consumption and high reliability. To put it simply, it represents a better way to travel in the future.



R6 diesel engine
for railcars and special vehicles

The practical master of thrift: The R6 diesel engine is a horizontal engine that displays its class in a variety of applications. It is available in three different versions. The smallest version offers 294 kW and 1,900 Nm. The largest, 390 kW and 2,300 Nm. The version in between provides 353 kW at 2,200 Nm. All three engines are well below the emission level Stage IIIB of the EU-non-road-directive 97/68/EC-2011/88/EC in effect since 2012. Thanks to the engineering concepts of single-stage exhaust-powered turbocharging, charge air cooling and an SCR system (selective catalytic reduction). In spite of the impressive 12.8 liter displacement, the engine is characterized by exceptionally low fuel consumption. Even its maintenance requirements are surprisingly low.  



V12 diesel engine - V2862T3/L3
for railcars and locomotives

The new dimension: the V12 diesel engine is currently the largest and most powerful engine for railcars. It offers convincing output values and is particularly economical. High torque, low fuel consumption and low maintenance costs make it also interesting for applications in locomotives. Due to its technology concept consisting of single-stage turbocharging, cooled exhaust gas recirculation and SCR system (selective catalytic reduction) it significantly undercuts the emission levels of Stage IIIB of the EU non-road directive 97/68/EC-2011/88/EC. This V12 diesel engine definitely gets things going. 

The engine principle that was invented by Rudolf Diesel still represents a successful engine concept today. We have also developed a few ideas to keep it that way. Even after 100 years, the principle of self-ignition of the fuel injected into the combustion chamber remains the defining feature of this engine. Targeted innovations, however, continue to open up new perspectives.

Reusing Waste Heat and Tremendous Savings on Fuel Cost ...

The SteamTrac System is based on a closed steam circulating process. It converts some of the waste heat into useful torque. This torque is fed back into the driveline. Fuel savings of up to 12% (and correspondingly reduced CO2 emissions) can be achieved in this way – or engine output can be increased without higher fuel consumption.
