Product information ABB Turbocharging TPS..-D/E Power and productivity for a better world™

All-round performance 75 % of a diesel or gas engine’s power relies on one vital component – the turbocharger. The ultimate goals of turbocharged engine development are higher power and efficiency – two areas in which ABB’s TPS turbochargers make a vital contribution. ABB developed the TPS . . -D / E series of small turbochargers for modern highspeed diesel engines and gas engines as well as for small medium-speed diesel engines used in cogeneration power plants, as marine engines, in gensets, in locomotives and in heavy-duty mining vehicles. The TPS concept provides a robust and reliable platform...

Proven reliability Simple, rugged and compact – the TPS . . -D / E combines low running costs with total reliability. Variable turbine geometry Four frame sizes cover a wide range of applications. Available options include HFO and high-temperature packages as well as variable turbine geometry for applications with changing operating or ambient conditions. Tested to the limit A comprehensive series of qualification tests confirms the total reliability and safety of ABB turbochargers. Ranges of turbocharger efficiency ␩ TC [%] E-version D-version Turbocharger efficiency This turbocharger series...

Design features Turbine and compressor Range of turbine efficiency Large nozzle ring area Small nozzle ring area 85 Compressor pressure ratio Turbine efficiency (total to static) Turbine expansion ratio Turbine The mixed flow turbine with nozzle ring ensures the very high efficiency and large volume flows users expect of turbochargers for 4-stroke diesel and gas engines. A key feature of this turbine is its different nozzle ring area per trim for part-load and full-load optimization. The TPS . . -D / E turbine concept is suitable for both constant pressure and pulse turbocharging. Volume flow...

Stability and compactness Over 50,000 ABB turbochargers with plain bearings in operation around the world provide an unrivalled experience base for TPS plain bearing technology. The axial thrust bearing is positioned between the radial bearings - a feature that also contributes to the compact rotor design. The radial bearing bushes run on a squeeze oil damper. This proven bearing technology guarantees long-term reliability for the TPS.. -D/E Burst protection The increased brake mean effective pressures of diesel and gas engines have led to considerably higher power densities for the turbocharger...

Optimized casings and interfaces TPS . . -D / E casings have been optimized for applications on 4-stroke engines, with an emphasis on best possible fluid dynamics, minimized thermal stress and total containment. Turbine and compressor washing are catered for. All casings, including suction branches and the gas outlet elbow, are also prepared for the connection of temperature and pressure measurement sensors. ABB turbocharger qualification tests Tests include: – Resonance endurance – Low cycle fatigue – Temperature cycle – Hot shutdown – Oil tightness – Compressor containment – Turbine containment...
