2011 PORSCHE CAYENNE fuel pressure

Boasting outstanding perform-
ance and ef ficiency, the Cayenne
Diesel is ideal for longer journeys
– of fering high levels of torque,
while fuel consumption remains
l o w.
Its new 3.0 -litre V6 turbo - diesel
engine is now more powerful and
refined, and approximately 20 kg
l i g h t e r.
1) The unit generates
180 kW (245 hp) and maximum
torque of 550 Nm. The sprint
to 100 km/ h (62 mph) requires
just 7.6 seconds. Top speed
is 220 km/ h (137 mph). Fuel
con sumption now comes in at
just 7.2 l/100 km (39.2 mpg) in
the EU cycle.
2)
Direct fuel injection comes cour-
tesy of a common-rail injection
system. The piezoelectric
injectors now enable multiple
injections at a pressure of up to 2,000 bar, ensuring optimum
distribution of the air/fuel mixture
– for improved dynamics.
The new turbocharger on the
Cayenne Diesel features Variable
Turbine Geometry (V TG, p. 40).
Combined with optimised channel-
ling of the intake air, it enhances
the charging ef fect, thereby
generating a higher output and
impressive torque, even at low
engine speeds.
The standard eight-speed
Tiptronic S includes gearshif t
controls on the steering wheel.
Transmit ting the high torque
of the Cayenne Diesel smoothly
and ef fectively, the eight gears
are designed to facilitate both
economical driving
with low fuel
consumption and
performance
driving with em phatic accele ration.

Understatement coupled with
clear statements: lower fuel
consumption, faster acceleration.
Supreme engineering that speaks
for itself. In short, every thing
you’d expect from a Turbo.
Another clear statement is the
distinctive sound from the t win
dual-tube tailpipes. Produced by
the 4.8-litre t win -turbo V8 engine
that delivers 368 kW (500 hp)
and features direct fuel injection
(DFI, p. 38). The car has a top
speed of 278 km/ h (173 mph)
and the benchmark sprint from
0 to 100 km/ h (62 mph) is com-
pleted in 4.7 seconds. Maximum
torque is 700 Nm. Here too, fuel
consumption has been reduced
by
23 % and CO2 emissions by
2 5 % .

Optimum traction and safet y are
provided by Porsche Traction
Management (PTM, p. 44) active
all-wheel drive. Also connecting
the car to the road are the 19 -inch Cayenne Turbo wheels.
The chassis on the Cayenne Turbo
is equipped as standard with air
suspension featuring self-levelling
and ride-height control, as well
as Porsche Active Suspension
Management
(PASM, p. 51). This
electronic damping control sys-
tem offers continuous adjustment
of the damping forces
on each
wheel – depending on
current
road conditions and driving st yle.
This enables greater car control,
improving safet y and comfort.
Comfort is also key in the
Cayenne Turbo interior. Standard
equipment comprises an interior
package in smooth-finish leather,
a rooflining in Alcantara and an
electrically adjustable steering
column.
Also fit ted as standard: the
BOSE® Surround Sound System,
Porsche Communication
Management (PCM) with navi-
gation module, adaptive sports
seats with comfort memor y package (18-way), Tyre Pressure
Monitoring (TPM, p. 57), auto -
matic headlight activation and
automatically dimming exterior
and interior mirrors.
Exterior features exclusive to
the Cayenne Turbo include
Bi-Xenon main headlights with
Porsche Dynamic Light System
(PDLS, p. 61), larger air intakes
and a distinctive ‘power dome’ on
the engine lid – a clear reference
to the enormous potential within.
Following our long established
principles,
the Cayenne Turbo
blends phenomenal performance
with outstanding comfort and
efficiency. It does so in st yle but
without ever compromising on
any one in particular. Because we
believe that less can also mean
more.
Reduced weight, lower fuel consumption, fewer emissions.
At Porsche, we believe less is more.

consistently within a specific
temperature range. The engines
in the Cayenne models are
therefore designed for ef ficient
cooling.
In order to reduce the frictional
losses that occur during warm -up,
all Cayenne models feature com-
prehensive thermal management.
Using intelligent control, it
activates the dif ferent cooling
circuits individually and on de-
mand, thereby ensuring that the
optimum operating temperature
for the engine and transmission
is reached more quickly. This
minimises friction – and keeps
fuel consumption and CO
2 emis-
sions low.
The V8 engines have an enhanced
coolant management system
offering effective temperature
control throughout the engine.
While 20 % of coolant flows longi-
tudinally through the crankcase,
the remaining 80 % serves the
cylinder heads using the proven
cross-flow principle (from hot to
cold).
On all Cayenne models, the piston
heads are cooled using oil-spray
jets integrated within the main
lubrication system.
The entire cooling system is
designed for prolonged heav y-
dut y use, e.g. of f-road driving
or heav y towing and carrying
applications.Lubrication.
The V8 engines use dry-sump
lubrication to ensure a consistent
supply of oil in all load conditions,
especially in of f-road terrain.
The oil reservoir is located inside
the engine. This saves on space
and reduces weight.
Oil is circulated around the V8
engines using a demand- driven
pump. This has been designed
for the toughest driving scenarios
on and off road, including per-
formance driving and extreme
gradients. The V6 engines have a wet-sump
lubrication system.
Ensuring a
reliable supply of oil, no mat ter
how challenging the driving
conditions.
Direct fuel injection on the
diesel engine (common-rail
injection system).
On the Cayenne Diesel, direct
fuel injection comes courtesy of
a common -rail injection system.
The injection pressure is now up
to 2,000 bar, ensuring optimum
distribution of the air/fuel mixture
– for greater performance. The
piezoelectric injectors provide
flexible injection rate
adjustment,
using exactly metered quantities
of fuel, with multiple injections
for each power stroke to deliver
smooth combustion.
Cooling systems.
A high -performance engine can
only maintain its maximum
capabilit y over a long service life
if all components are operating
Direct fuel injection (DFI).
DFI injects fuel directly into the
combustion chamber at up to
120 bar with millisecond precision
using electromagnetic injectors.
The injector position and spray
geometry have been carefully
designed to improve output,
torque, fuel economy and emis-
sions. The swirling of the fuel as
it enters each chamber increases
the mixing of air and fuel, thereby
enhancing combustion. By form-
ing the air/fuel mixture directly
in the combustion chamber, DFI
contributes to engine cooling.
As a result, it was possible to in-
crease the compression ratio and
therefore power and efficiency.

Compression with precision.
Essential for getting right to the point.

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.

Porsche Ceramic Composite Brake (PCCB)
To do this, the engine manage-
ment system adjusts the gener-
ator current depending on the
brake pedal position, recovers
part of the kinetic energy and
stores it in the bat tery. When
the pressure on the brake pedal
exceeds a certain threshold, the
brakes are applied.
Porsche Ceramic Composite
Brake (PCCB).
Available as an option on all
Cayenne models, the Porsche
Ceramic Composite Brake (PCCB)
has already proven its abilit y to
cope with the harshest require-
ments of the racetrack. It is avail -
able in conjunction with 20-inch
wheels or larger for the Cayenne
Turbo and with 19-inch wheels or
larger for all other Cayenne models.
The discs are made from a
specially treated carbon-fibre
compound that is silicated
in a high-vacuum process at
approximately 1,700 °C. The
resulting material is not only
much harder than cast iron, it
is also more resistant to heat.
Even at high temperatures, the
thermal resistance of the PCCB
disc ensures outstanding dimen-
sional stabilit y. The ceramic
material is totally resistant to
corrosion and offers excellent
acoustic damping properties.
PCCB enables shorter braking
distances – no mat ter how tough
the driving conditions. The pedal
response is fast and precise with
only moderate input required.
Excellent fade resistance ensures
greater balance when slowing
from high speed.The key advantage of PCCB is
a total weight saving of approxi-
mately 50 % compared with
equivalent cast-iron discs. As well
as enhancing performance and
fuel economy, the unsprung and
rotating masses are lightened.
The results: greater comfort
and road-holding on uneven road surfaces plus bet ter handling
and agility.
Optional for all Cayenne
models.
Recuperation.
The electronic engine manage-
ment system on the Cayenne S
Hybrid controls the braking
process so that, when the brake
pedal is actuated, as much
expended energy as possible
can be harnessed by the electric
machine’s generator and stored
in the 288-volt nickel metal
hydride (NiMH) bat tery. This is
referred to as recuperation.
