Mercedes-AMG Develops Electric Exhaust Gas Turbocharger

[ad_1]

Mercedes-AMG is implementing electric exhaust gas turbochargers in its next vehicle generation. The turbocharger features an electronically controlled electric motor which drives the compressor wheel before the wheel takes over the exhaust gas flow.

The electric exhaust gas turbocharger was developed in partnership with Garrett Motion. The technology comes from Formula 1 and is intended to combine the benefits of a small turbocharger with fast response times that achieves relatively low peak performance and of a large turbocharger with high peak performance but delayed responses.

A slim electric motor measuring around 4 cm is integrated directly on the charger shaft between the turbine wheel on the exhaust side and the compressor wheel on the fresh-air side. The electronically controlled electric motor drives the compressor wheel before the wheel takes over the exhaust gas flow, which significantly improves responsiveness even at idle speeds and across the entire engine-speed range. The turbocharger is powered by a 48-volt on-board electrical system and can achieve speeds of up to 170,000 rpm, which enables a very high air flow rate. Along with the electric motor and power electronics, the turbocharger is connected to the combustion engine’s cooling circuit.
