A
turbine wheel is a part of a machine that spins around really fast. It is shaped like a wheel with blades, and it helps to generate power or motion by using the force of a liquid or gas flowing through it.

For the first time Mercedes - AMG is combining the advantages of twin - scroll technology in the V8 engine
with turbine wheels mounted in anti-friction bearings.
Nineteen - inch light - alloy rims in aerodynamically optimised ten - spoke
turbine wheel design created exclusively for BMW ActiveHybrid 7 as well as model designations on the luggage compartment lid, the C - pillars behind the side windows and on the door cutouts clearly set aside the hybrid models from their «regular» counterparts right from the start.
BMW ActiveHybrid comes as standard with model - specifi c 19 - inch light - alloy rims in aerodynamically optimised ten -
spoke turbine wheel design.
* Using a titanium - aluminum
alloy turbine wheel and aluminum alloy compressor wheel, the turbocharger features a shape - optimized compressor wheel that improves boost response and increases low - end and mid-range torque.
The new turbochargers sport
lighter turbine wheels, and each turbo is managed by a new electronically - actuated wastegate.
The turbocharger itself is an in - house creation and CNC'd from aluminum and features a carbon -
fiber turbine wheel.
My test vehicle added further bravura with Italian Racing Red metallic paint ($ 550) and gorgeous 22 - inch
polished turbine wheels (a steep $ 4000 but so fetching they're probably worth it).
Large, 21 - inch, zillion - spoke
turbine wheels add a dose of aggression to the PHEV's stance, while the rear diffuser brightwork downplays the exhaust tips.
A larger billet compressor wheel and an
upgraded turbine wheel have required machining to the turbo housing to make them fit.
Bore and stroke of 86 mm (3.386 in) and 85.8 mm (3.378 in) are used, along with a 9.8:1 compression ratio and twin turbos with titanium -
aluminide turbine wheels.
The mid-mounted 2.0 L engine had both a supercharger and a turbocharger (with a
ceramic turbine wheel), pistons made from magnesium fibre - reinforced metal (FRM), a distributor-less ignition system and a resin intake manifold.
The increased performance compared with the Panamera Turbo can be attributed to two main enhancements: Improved turbochargers with titanium -
aluminium turbine wheels and modified engine control.
With the mixed -
flow turbine wheel, the moment of inertia is low, the electrically operated wastegate works extremely precisely and intercooler integrated into the intake manifold results in short distances for the gas mixture to travel.
The ActiveHybrid 7 comes standard with 19 - inch light - alloy rims in an aerodynamically optimized ten - spoke
Aero turbine wheel design, unique to this model.
A newly developed turbocharger fitted to the GT model we tested featured a
titanium turbine wheel and magnesium compressor wheel, to aid boost and throttle response.
Low inertia 78 mm Q -
Trim turbine wheel design for faster spool and better transient response at no cost to peak horsepower thanks to Magnum's free full system custom engine simulation.

That's thanks to an aerospace - grade aluminum compressor wheel which is 15 percent smaller in diameter, and an
advanced turbine wheel 10 percent smaller across, made from a high temperature - resistant, space - age alloy called Inconel (consisting of nickel, chromium, and iron).
It operates with a
larger turbine wheel so that the reengineered turbocharger can deliver a particularly large quantity of air.
Lot # 1568 - This 7 - up Edition Mustang in Emerald Green with a white top and white leather articulated sport seats rides on aluminum
GT turbine wheels.
The turbine wheel is what you are looking at here.
The shaft that connects the compressor wheel and
the turbine wheel broke.
The exhaust streams arrive at
the turbine wheel through physically separate channels — for optimised gas cycles.
Exhaust from pairs of cylinders is gathered in alternating sequence, maximizing pulse energy to
the turbine wheel for quick torque delivery.
Porsche is recalling certain 2011 and 2012 Panamera Turbo and Turbo S sedans and the Cayenne Turbo for a problem with
the turbine wheel of the turbocharger.A summary of the problem on the NHTSA site...
Two configurations are offered, with either a Midnight Silver Metallic exterior and Grey
Turbine wheels with a black interior and carbon - fiber trim, or a Red Multi-Coat exterior and Silver Turbine wheels with a tan interior and Obeche trim.
Combined with two separate exhaust ducts in the exhaust manifold, this makes it possible to control the exhaust gases on
the turbine wheel separately.
Twin - scroll turbocharging means that the exhaust stream of cylinders one and four follow a separate path to
the turbine wheel from cylinders two and three.
The exhaust streams arrive at
the turbine wheel through physically separate channels — for optimized gas cycles.
This means that the exhaust stream from cylinders 1 and 4, and the exhaust stream from cylinders 2 and 3, follow separate spiral - shaped paths to
the turbine wheel.
The cross-bank exhaust manifolds for the all - new BMW M5 have also been modified to optimize the flow of energy from the exhaust gas to
the turbine wheels of the two twin - scroll turbochargers ensuring the best possible gas - exchange cycle.
Instead of
the turbine wheel, it integrates a compact electric motor.
The new turbocharger, with larger impeller and
turbine wheels, can build up a boost pressure as high as 1.2 bar.
The rims in
the turbine wheel look also carry the precious metal as well as one of the numerous UA logos.
The result is a cleaner - burning engine that maximizes the exhaust's pulse energy flowing to
the turbine wheel.
«The new turbocharger's
turbine wheel is 6 percent larger, and the compressor wheel diameter is 10 percent larger, resulting in a 20 percent increase in boost pressure.
While the most common type of petrol turbocharger today, the radial turbocharger, features a radial exhaust gas flow to
the turbine wheel, the new Continental turbocharger features a radial - axial flow — hence the name RAAX.
This makes it possible to substantially reduce the size of
the turbine wheels, and to reduce the mass moment of inertia by approximately 40 percent.
It is the first time ever that Mercedes - AMG combines the winning cards of the twin - scroll technology in the V8 unit with
the turbine wheels mounted in anti-friction bearings, reducing friction inside the exhaust - gas turbocharger and ensuring a super-efficient gas flow.
Super-alloy allows
the turbine wheel in the turbocharger on Ford Fusion and Focus ST 2.0 - litre EcoBoost engines to run hotter with greater durability.
The separation of exhaust flow is continued until the exhaust gas reaches
the turbine wheel, building up ongoing pressure on the two Twin Scroll Turbochargers not impaired by any kind of counter-pressure.
The turbocharger compressor housing had four vanes made from heat resistant Inconel alloy surrounding
the turbine wheel (on the inlet side of it) that would fluctuate based on engine load and transmission gearing above 2,000 rpm to allow for increased airflow into the engine as needed.
The turbine wheels and other chrome elements provide a spectacular contrast to the black paintwork.
