“The eSupercharger delivers significant gains in the driveability, power and emissions reduction of downsized internal combustion engines, and we are delighted to demonstrate the potential of our system in conjunction with MAHLE Powertrain UK,” said Aeristech CEO, Bryn Richards. “Our 48v architecture could prove to be a vital tool in meeting stringent fleet CO2 reduction targets, raising economy and improving driver enjoyment.”
Using an eSupercharger also has advantages for emissions control. Because it is fitted to the inlet side of the engine thermal mass in the exhaust stream is reduced, which helps to maintain catalyst temperature, especially at lower speeds and loads.
Aeristech’s motor control strategy separates commutation and power control which means the electrical switching frequency need be no higher than running speed. This approach reduces the cost of many key switching components while ensuring accurate high-transient speed control.
Richards added: “The engine in MAHLE’s C-segment demonstrator vehicle at LCV 2015 generates a maximum power output of 193kW and 33 Bar BMEP output, the latter is in excess of any gasoline engine currently available in series production.”
