Mercedes AMG F1 engine achieves 50 % thermal effectivity


The Mercedes AMG Formulation 1 staff’s 2017 season has been a

profitable one
to this point, and though the drivers deserve a lot of the
credit score, the staff itself has performed some outstanding issues as

Notably, Mercedes’ present F1 engine achieved 50 %
thermal effectivity for the primary time.

Within the video, Owen Jones, head of efficiency and controls at
Mercedes AMG Excessive Efficiency Powertrains, the unit accountable
for Mercedes’ F1 engines, discusses how important 50 %
thermal effectivity is in racing.

Thermal effectivity is the potential vitality burned in gasoline.
Engines, subsequently, should extract as a lot helpful work, or energy,
from gasoline as doable. Mercedes’ current dyno checks confirmed the

1.6-liter turbocharged V-6 scored in extra of 50 %
thermal effectivity; greater than half of the obtainable vitality in
the gasoline is now doing helpful work, not merely being wasted as
warmth and noise. Many engines solely obtain round 35 %
thermal effectivity.

Owen says Mercedes spent a whole lot of time on the basic
thermal dynamic ideas similar to fuel change processes and
combustion. From there, the staff wanted to scale back waste and
losses via low friction. Oils have been developed to scale back
waste and friction, and exhaust waste warmth is transformed into
electrical energy—the whole F1 energy unit can also be paired with
two motor-generators. Certainly one of these aids the engine in
driving the rear wheels whereas the opposite is used to spool up the

The perfect half is that this similar powertrain will find yourself in
a street automotive! The
Mercedes-AMG Undertaking One will characteristic a model of the
engine detailed right here, so seize a more in-depth take a look at its thermal
dynamic properties proper up above.
