eBooster delivers boost on demand until an engine's turbocharger catches up and takes over.
The challenges faced by engine developers to manage transient response times with turbocharging could be solved by Borg Warner. At CONEXPO-CON/AGG, the company showed its eBooster electrically-driven compressor, which is now available to off-highway OEMs.
Using a 48-volt electric supply, the eBooster delivers boost on-demand until an engine’s main turbocharger catches up and builds enough pressure to take over. At this point, the electrically-driven compressor stops running.
This technology is said to assist smaller, more fuel-efficient engines in delivering the power and torque of larger displacement engines. Borg Warner’s eBooster is equipped with a water-cooled core, and permanently lubricated bearings.
