Electric Boosting Technologies

As a global product leader in clean and efficient technologies, BorgWarner drives innovation by electrifying its boosting technologies. Equipped with high-performance electric motors, the company’s cutting-edge solutions developed for 12V, 48V and high-voltage vehicles offer fast time-to-torque for a fun-to-drive experience while enabling improved fuel efficiency and reducing emissions. Some of the systems are also capable of recovering energy for additional efficiency benefits.

Light Vehicle Solutions

eBooster® Electrically Driven Compressor

BorgWarner’s eBooster® electrically driven compressor supplements conventional turbocharging systems. Placed either upstream or downstream of the regular turbocharger, the eBooster solution improves boost pressure and transient engine response at low engine speeds. In doing so, the technology virtually eliminates turbo lag.

The eBooster® permits the development of small and efficient high-performance turbocharged engines whose dynamic response matches that of large non-supercharged engines of the same output class. The superiority of the eBooster® was impressively demonstrated in close cooperation with various customers for gasoline engines as well as for diesel engines.

Commercial Vehicle Solutions

eBooster® Electrically Driven Compressor

BorgWarner’s water-cooled eBooster® electrically driven compressor for commercial vehicles provides engine boost pressure whenever the turbocharger turbine can’t. With a maximum speed of 100,000 rpm, the eBooster offers a continuous power of 10kW and peaks at 23 kW.

eBooster CV

eBooster® Electrically Driven Compressor

Features

  • Great for larger engines (>5 l)
  • Compact design with external power electronics
  • Water-cooled system

Benefits

  • Enhanced performance for commercial vehicles
  • Combines optimized fuel economy and driver enjoyment with lower emissions
  • Improved torque and response for smaller and lower-speed engines

eTurboTM

As a single-machine solution for electrified boost, assistance and recuperation, BorgWarner’s eTurboTM is capable of converting exhaust energy to electrical energy. In addition, the solution offers increased torque at low engine speeds and improves time-to-torque.

eTurbo CV

eTurboTM

Features

  • Features an integrated electric motor that provides additional boost air
  • Available for 48V- and high-voltage applications
  • Electrical function can be switched off for normal turbocharger function

Benefits

  • Up to 13 kW continuous power and 23 kW peak power
  • Reduces turbo lag and offers faster time-to-torque
  • Improves fuel economy and lowers emissions

eTurbocompound

Even though modern turbocharged combustion engines are remarkably efficient, useful energy can still be found in the exhaust gas flow. Positioned downstream of the aftertreatment system, BorgWarner’s turbine-driven, water-cooled generator eTurbocompound uses the remaining waste heat to generate electrical energy.

eTurbocompound

Features

  • Water-cooled and easily scalable turbine
  • Individually adjustable turbine and generator speed

Benefits

  • Can be used for many vehicle types
  • Facilitates cost-effective recovery of heat energy from the exhaust gas flow
  • Minimal effects on engine operation or vehicle packaging

Organic Rankine Cycle Turbines/Pump-expanders

To make use of fuel energy wasted as heat during the combustion process, BorgWarner developed the Organic Rankine Cycle (ORC) waste heat recovery system. Combining multiple technologies such as a heat exchanger within an optimized overall package, the ORC generates electrical power while recovering about 50 percent of the energy wasted as heat.

ORC Expander
