2011 PORSCHE CAYENNE ignition

response, even at low revs and
road speeds. This is particularly
useful when driving in urban
traf fic. The supercharger has a
low-temperature water cooling
system for cooling the charge air.
Variable Turbine Geometry in
the Cayenne Diesel.
The turbocharger in the
Cayenne Diesel features Variable
Turbine Geometry (V TG). The
gas-flow from the engine is
channelled onto the turbines via
electronically adjustable guide
vanes. By changing the vane
angle, the system can replicate
the geometry in all t ypes of
turbo, large or small , and thus
achieve the optimum gas-flow characteristics. As a result, even
at low engine rpm, the turbine
speed is maximised. For a sig-
nificant increase in boost pres-
sure, excellent cylinder charging
plus greater power and torque.
Electronic engine management.
Cultured performance in all
driving scenarios requires com-
prehensive engine control. The
electronic engine management
system does this by continually
monitoring the relevant input data
from a variet y of sophisticated
sensors. This data is then com-
pared with a corresponding set of
reference values. Based on this
information, a range of key engine
functions, e.g. ignition and in-
jection timings as well as injection
quantities, are seamlessly and
automatically adjusted. Other
major functions include on -board
recuperation. It ensures that the
on -board power supply is only
replenished while the vehicle is
on the overrun. This boosts fuel
economy as well as performance,
and ensures maximum engine
output during acceleration. All
this goes unnoticed by the driver,
apart from the obvious benefits:
lower fuel consumption and CO
2
emissions plus greater power and
torque at all times.
Exhaust system.
The light weight exhaust systems
in the Cayenne models are made
from special, long-life stainless
steel. The key features of the cata-
lysts are high ef ficiency, faster
warm -up and a long service life.
Sports exhaust system.
Available as an option on the
Cayenne and Cayenne S, the
sports exhaust system
1) provides
an even more distinctive sound.
For the looks to match, it comes
with a specially designed set
of t win dual-tube tailpipes with
a high-gloss finish.
All exhaust systems, standard and
sports, comply with the stringent
EU5 emissions legislation.
2)
Turbocharging system in the
Cayenne Turbo.
In the Cayenne Turbo, the engine
is assisted by t win turbocharger
units arranged in parallel –
one for each bank of cylinders.
Incoming air is passed through
a filter and compressed by the
turbine units. Its temperature is
then reduced in the t win inter-
cooler system, which improves
cylinder charging and limits
thermal loads on the engine.
Supercharging system in the
Cayenne S Hybrid.
The engine in the Cayenne S
Hybrid is equipped with a
supercharger. For a more direct
Air intake system.
The Cayenne models are all
equipped with a resonance air
intake system. This technology
uses the pressure waves
generated by the inlet valves
to ‘force’ air into the engine.
The ef fect is enhanced in the
Cayenne and Cayenne S by a
t wo -stage intake manifold. This
variable geometry combines
all the benefits of a long intake
tube (higher torque at low rpm)
with those of a shorter length
(more power at higher rpm).
The result: highly impressive
torque ratings across the entire
engine speed range.

Thanks to single-spark coils on
each of the cylinders, the entire
ignition system on the petrol-
engined models, with the
exception of the spark plugs,
is maintenance -free.
These modest service require-
ments mean less waste disposal
and fewer demands on natural
resources. They also lower the
cost of ownership while keeping
your car on the road.The Cayenne S Hybrid doesn’t
require any additional servicing.
Service intervals for the Cayenne
models are dependent on a range
of factors, including local fuel
qualit y. For full details of service
intervals in your country, please
consult the relevant price list
or contact your Porsche Centre.
Materials and recycling.
Owning a Porsche should be a
lasting pleasure with minimal
impact on the environment. This
Porsche principle can be summed
up in one word: sustainabilit y.
The light weight exhaust on the
Cayenne models, for example,
is constructed from long-life
stainless steel.
Every Porsche model is entirely
free of asbestos, CFCs and
components manufactured using
CFCs. All legal requirements in
respect of recycling are fulfilled.
Materials are clearly labelled for subsequent identification and
sorting to facilitate ef ficient
recycling.
While more than 95 % of the car
can be recycled using current
technologies, the chances are
your Cayenne may never need
recycling at all. After all, t wo
thirds of all the cars we have ever
made are still on the road today.

environmental issues, please

Servicing.
With lengthy service intervals
and long-life components, vehicle
maintenance is kept to a min-
imum. In the case of the oil filter,
for example, all that ’s replaced
is an easily recyclable paper
element. The oil filter casing
remains on the car.
All moving parts inside the engine
are fully self-adjusting. The valve
clearances, for instance, feature
automatic hydraulic control.
Noise.
As paradoxical as it may seem,
the distinctive Porsche sound is
also created by what you don’t
hear – the absence of unwanted
noise. Naturally, its main origin is
deep within the engine. But that ’s
not all. Our holistic approach
to vehicle design also extends
to the acoustics. Which is why
we’ve optimised them for the
entire car.
To minimise ‘play’ bet ween com-
ponents, we’ve used stronger,
lighter and more temperature-
resistant materials. This reduces
mechanical noise. Large-volume
silencers and air intake manifolds
also help to eliminate noise –
throughout the life of the car.
Tyre noise has been drastically
reduced in collaboration with
our of ficial t yre partners. Wind
noise levels have also been
lowered thanks to aerodynamic
refinements.
All that remains is a sound that is
pure Porsche.
