On several Rostock test beds, it is also possible on to undertake electrical testing of complete gensets, that is, an engine combined with a power generator, up to a maximum of 10 megawatts. In the field of after-treatment of exhaust gases, Caterpillar Motoren is working on systems for reducing sulfur and nitrogen oxide, referred to as SCR (Selective Catalytic Reduction).
A particular focus for the CDU Parliamentary Group was the development of dual-fuel engines at Caterpillar Motoren Rostock. These have arisen from the trusted and reliable MaK diesel engines and offer a high degree of flexibility in fuel selection. Dual-fuel engines may be operated using liquefied natural gas (LNG), allowing them to achieve emissions which remain significantly lower than those produced by comparable diesel engines. Sulfur emissions are completely eliminated, soot particle emissions are reduced by more than 90%, and nitrogen oxide emissions by more than 75%. Extensive monitoring of engine operation and the fuel system is facilitated by cutting-edge engine control modules. This also guarantees a high level of safety even in gas operation. Dual-fuel engines therefore represent a highly promising alternative for ship propulsion systems in the future.
Caterpillar’s long-standing partner, Zeppelin Power Systems, is available for the customized development of dual-fuel engine projects. The company undertakes all work from project design and development, to construction, installation, commissioning and worldwide after-sales service. Zeppelin Power Systems has been Caterpillar’s reliable sales and service partner for over 60 years in Germany, as well as in many Eastern European countries and in the CIS.
