The Mercedes AMG Method 1 group’s 2017 season has been a

profitable one
so far, and though the drivers deserve a lot of the
credit score, the group itself has accomplished some outstanding issues as
effectively.

Notably, Mercedes’ present F1 engine achieved 50 p.c
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 p.c
thermal effectivity is in racing.

Thermal effectivity is the potential power burned in gasoline.
Engines, due to this fact, should extract as a lot helpful work, or energy,
from gas as doable. Mercedes’ latest dyno checks confirmed the

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

Owen says Mercedes spent loads of time on the elemental
thermal dynamic ideas resembling gasoline alternate processes and
combustion. From there, the group wanted to cut back waste and
losses by way of low friction. Oils had been developed to cut 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 in all these aids the engine in
driving the rear wheels whereas the opposite is used to spool up the
turbocharger.

The very best half is that this similar powertrain will find yourself in
a highway automotive! The
Mercedes-AMG Venture One will function a model of the
engine detailed right here, so seize a more in-depth have a look at its thermal
dynamic properties proper up above.
