AMG has detailed its new-generation turbocharger, which will be put in queue by a small electric motor
With the V8 set to make room for the ovens, Mercedes-AMG range, Affalterbach need to start squeezing a ridiculous amount of power from tiny engines. With a specific output of more than 200bhp per litre, the ‘M139′ that the powers of the’ 45 line-up is a good starting point, but it will need help, in the form of electricity.
We are not talking about hybridization, however. Nope – AMG will be sticking to the engines inside of its turbochargers. Mercedes ‘ performance arm already has an e-turbo in the final phase of development, which will be supported by a four-centimeter engine, electric motor.
It is integrated on the loader of the tree, sitting between the turbine and the compressor wheels. Powered by a 48-volt electrical subsystem, it is able to spin the compressor wheel before the exhaust gases hit it.
This leaves Mercedes free to extract more power from smaller engines without the large amount of turbo lag. The system – this is done in partnership with Garrett’s Movement, and uses F1-derived technology could kill the lag completely.
The new turbo is capable of spinning up to 170 000 tr / min, slightly faster than the more conventional snail used in the M139. The turbo, its engine and all the associated electronics are hooked up to the engine cooling circuit in order to ensure that nothing is overheating.
We’ve seen some electric compressors used in the production of cars before, and a few of Mercedes, with some of its 3.0-liter inline-six boosted by a 48-volt electrical appliances. However, these configurations are not directly comparable, since they involve small motor units work together with the turbochargers. The new e-turbo is very different from the beast and stands to completely change the character of turbo cars as we know them today.
The imminence of the death of the AMG V8 is still a huge shame, of course, but these fancy new turbos will go a long way to go for the 4.0 litre potential of the landing.
