Mercedes AMG F1 engine achieves 50 % thermal effectivity


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

profitable one
up to now, 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 vital 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 attainable. Mercedes’ latest dyno checks confirmed the

1.6-liter turbocharged V-6 scored in extra of 50 %
thermal effectivity; greater than half of the accessible 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 number of time on the basic
thermal dynamic rules reminiscent of gasoline change processes and
combustion. From there, the staff wanted to scale back waste and
losses by low friction. Oils have been developed to scale back
waste and friction, and exhaust waste warmth is transformed into
electrical energy—the entire F1 energy unit can be paired with
two motor-generators. One among 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 automobile! The
Mercedes-AMG Undertaking One will function a model of the
engine detailed right here, so seize a better take a look at its thermal
dynamic properties proper up above.
