TPR Turbocharger

Features:

• Compact, robust and rigid construction
• Uncooled gas casings
• Integral axial turbine without damping wire
• Boreless radial compressor wheel and compressor stage with air recirculation
• High pressure ratio at high performance level
• Plain bearings with squeeze oil film damper and free floating thrust bearing disc
• Gas outlet casing with integrated patented foot fixation and drain
• Variable Turbine Geometry (VTG) with actuator and control logic
  (boost pressure monitoring)

• Withstands high mechanical loads
• No water connections; no corrosion, no leakage
• High turbocharger efficiencies at all loads
• Wide compressor map; large surge margins and longer LCF capability
• Allows compliance with strict engine emission regulations
• Increased rotor stability and reduced friction losses; inclination compensation
• Small space demand, most compact and stiff; optional drainage points
• Easy removal and replacement of complete turbocharger, small footprint

• Enables extended locomotive range of operation
• Lower engine thermal load; increase in reliability and durability
• Decrease fuel consumption
• Increase locomotive load dynamics
• Smoothing out the ambient temperature and altitude effects on engine operating conditions
• Provide some new trade-off possibility for engine power pack optimization for traction specifics as a whole
