BorgWarner
has entered into a global agreement to supply its advanced eTurbo to a major
European OEM for use in a high-voltage hybrid passenger car. BorgWarner's
advanced electric boosting technology provides significant engine efficiency
and performance benefits while also enabling the automotive manufacturer to
meet increasingly strict emissions regulations.
This
will be the company's first application of its electrically assisted turbo
charger in a high-voltage hybrid vehicle. High-voltage hybrid vehicle
production with BorgWarner's electrified turbocharger is expected to begin in
September 2023.
“Our
eTurbo is a single machine solution with integrated power electronics able to
deliver robust electrified boost assistance and recuperation to a wide range of
vehicles,” said Joe Fadool, President and General Manager, BorgWarner Emissions,
Thermal and Turbo Systems, adding that “BorgWarner has a long, productive
history with this manufacturer, and we are excited to deliver enhanced engine
efficiency and performance to our client through this 400V hybrid application.”
The
eTurbo is a mechanical turbocharger equipped with an ultra-high-speed electric
motor coupled directly to the shaft. Customers have the choice of integrated or
semi-integrated power electronics. BorgWarner’s solution provides the
additional benefit of electrified boost assistance for enhanced response along
with customary turbocharger advantages.
It
delivers more than 200% faster transient boost response, along with a 50%
reduction in time-to-torque, nearly eliminating turbo lag and further
supporting engine downsizing. This electrified turbocharger is especially well
suited for Miller cycle engine concepts, delivering both improved fuel economy
and reduced emissions without any loss of performance.
BorgWarner’s
eTurbo can also serve as a generator, able to collect excess exhaust energy and
convert it into electrical energy. Repurposing the energy is effective for
accessory power or charging the battery, even enabling the use of a smaller
battery size. Additional benefits of the boosting technology include its
ability to decrease emissions through after treatment management and precise
air-fuel ratio control. By having the capability to increase engine
backpressure to reduce emissions, the eTurbo also supports on-demand exhaust
gas recirculation.
