An electrically assisted turbocharger (EAT) is an arrangement where an electric motor assists the gas-driven turbocharger in providing forced induction, particular at times when exhaust gas flow is insufficient to produce the desired boost. [1] Some systems integrate the motor inside a turbocharger, while others use a separate electric ...
This engine is part of Audi's modular 90° V6/V8 engine family. It shares its bore and stroke, 90° V-angle, and 90mm cylinder spacing with the Audi V6. The earlier V6 engines (EA837) used an Eaton TVS Supercharger instead of turbocharger(s). In 2016, Audi and Porsche released a new turbocharged V6 engine they dubbed EA839.
Using a turbocharger spool valve to increase exhaust gas flow speed to the (twin-scroll) turbine; Using a butterfly valve to force exhaust gas through a smaller passage in the turbo inlet; Electric turbochargers [51] and hybrid turbochargers. A similar phenomenon that is often mistaken for turbo lag is the boost threshold. This is where the ...
An electric-powered compressor assists the turbocharger when starting and accelerating from lower speeds, compensating for the turbo's lack of boost at low revs by adding extra pressure to the intake to smooth out power delivery. The compressor is also fed by the same 48V lithium-ion battery pack which supports the SQ8's mild-hybrid system.
The only mass-production W12 engine is the Volkswagen 6.0 WR12 48v, a four-bank design which was released in 2001.This engine has been used in several models from the brands Audi, Bentley, and Volkswagen, and in 2003 a turbocharged version was released.
The Audi R18 is a Le Mans Prototype (LMP) racing car constructed by the German car manufacturer Audi AG.It is the successor to the Audi R15 TDI.Like its predecessor, the R18 uses a TDI turbocharged diesel engine but with a reduced capacity of 3.7 litres and in a V6 configuration.
The engine from the Audi R8, a 3.6-liter V8, with (Honeywell Turbo Technologies) turbocharger, [48] was used as the initial powerplant for the Bentley in 2001. It produced 637 hp (475 kW) and over 479 lb⋅ft (649 N⋅m) of torque, via two 33.1 mm (1.30 in) intake restrictor, with boost pressure limited to 1.87 bar (27.1 psi) by regulations.
The Volkswagen Audi Group (VAG) AEB Engine is a line of mechanically-similar 1.8-liter, 20-valve, turbocharged, inline-four engines, designed, developed, and produced by the Volkswagen Group, and used in the various models, between 1993 and 2010.
