Modular Design Concept The new TCR turbochargers were designed to comply with the special demands made on HFO, MDO, biofuel and gas engines. They cover the complete range of possible applications, like propulsion and stationary engines, GenSets as well as traction engines, which are subject to the strictest requirements with regard to size and weight. As compared to the previous generation, these new turbochargers offer the advantage of increased compactness and less weight without any concessions regarding efficiency and performance. Advanced materials ensure extended service lives and...

Compressor By applying up-to-date 3D CFD and FEA calculations, a new compressor wheel geometry has been created with further improved efficiencies. Depending on the application, part-load and full-load optimisation is possible by means of flow area combinations. TCR turbochargers are equipped with the IRC system (internal recirculation) which is able to provide a larger compressor characteristic map with increased surge margin ability. The compressor wheel is milled from a high resistant aluminium alloy that can withstand intake conditions within a wide temperature spectrum. A new type of...

Maintenance Massive containment area The uncooled casing of the TCR series has been designed in accordance with the ‘pipeless engine’ principle. All supply pipelines are integrated in the casing. The compressor and turbine casings have measuring connections for monitoring the pressure and temperature. A speed pick-up is also included in the scope of supply. The casings, which are manufactured from SiMo steel or ductile cast iron respectively are designed and have been tested to be containment proof. Claw connections facilitate fast disassembly and allow the casing to be rotated into any...
