ENGINES DEVELOPED FOR
EFFICIENCY AND PERFORMANCE
1.1 PureTech 130
S&S engine / 6-speed manual gearbox
Designed and built in
France, the PureTech engines are a new family
of 3-cylinder petrol engines based on innovative,
efficient and economical technologies.
In 2014, the PureTech family gained a turbocharged
version, the
PureTech 130 S&S, the first petrol engine developed
by the PSA
PEUGEOT CITROËN Group to respect the Euro 6 standard.
Delivering plenty
of torque from low revs and across a broad brand, this
powertrain
revisits the driveability of petrol engines, further
enhancing the
punch and performance of the DS 4. The technologies used
set remarkable
standards in performance while keeping CO2 emissions on
a par with the
best: the PureTech 130 S&S engine with a 6-speed
manual gearbox
reduces fuel consumption and CO2 emissions by 19%
compared with its
4-cylinder predecessor (VTi 120).
Exceptional driving
pleasure
With its 3-cylinder layout and advanced technologies
(new-generation
turbocharger, direct injection, variable intake and
exhaust timing
system, etc.), this engine was developed to meet
stringent
specifications in performance and consumption, while
delivering
exceptional driveability.
Developing 96 kW (130 bhp) at 5,500 rpm (9% more than
its predecessor,
the VTi 120) and maximum torque of 230 Nm (44% higher
than the VTi 120)
from 1,750 rpm (vs 4,250 on the VTi120), the PureTech
130 S&S
engine meets high standards in performance. The 6-speed
manual gearbox
further increases driving pleasure.
Fuel consumption and
CO2 emissions on a par with the best in class
The DS 4 features significantly lower fuel consumption
with its:
-
optimised combustion: centrally positioned
high-pressure direct injection, optimised injector
position and spray
shape, increased injection pressure of up to 200
bars, improved
internal aerodynamics of the combustion chamber and
a variable intake
and exhaust timing function;
-
reduced internal friction: crankshaft sizing,
offset
cylinders a lubricated timing belt, use of a DLC
(diamond-like carbon)
low-friction coating on the piston pins, rings and
push rods, and an
oil pump controlled electronically to provide just
the right amount of
lubrication. In this way, friction is 30% lower than
on the best engine
made by the competition.
In consequence, the DS4 PureTech 130 S&S with a
6-speed manual
gearbox consumes 5l/100 km for CO2 emissions of 116g/km
with 16’’
wheels (5.1 l/100 km for CO2 emissions of 119g/km with
17’’ wheels).
1.2 BlueHDi 120 engine
/ 6-speed manual gearbox
At the end of 2013, DS rolled out a new generation of
diesel engines called BlueHDi, designed to anticipate
the Euro 6 standard.
The BlueHDi 120 engine with a 6-speed manual gearbox now
available on
the DS 4 allies excellent performance with particularly
low fuel
consumption and CO2 emissions owing to:
An optimised diesel
engine
The BlueHDi 120 engine with a 6-speed manual gearbox is
an upgrade of the 1.6l HDi Euro version:
improved internal efficiency, fewer mechanical losses
(special combustion chamber, new rings, new diamond-like
carbon coating).
The BlueHDi 120 with a 6-speed manual gearbox has
capacity of 1,560 cm3
for maximum power of 88 kW (120 bhp EEC) at 3,500 rpm
and maximum
torque of 300 Nm at 1,750 rpm. The Stop&Start
function with a
reinforced starter delivers a range of benefits
including lower fuel
consumption and greenhouse gas emissions. It is also
silent when
stationary. The engine takes no more than around 500 ms
to start up
again, less than the time necessary to put the car into
gear. Both
cut-out and re-start are transparent for the driver.
An innovative and
efficient exhaust line:
The BlueHDi 120
exhaust line comprises:
an oxidation catalytic converter positioned at the
engine exhaust to
eliminate the hydrocarbons (HC) and carbon monoxide (CO)
produced
through combustion;
an SCR (Selective Catalytic Reduction) module,
positioned upstream of
the particulate filter. With the injection of Adblue® (a
mixture of
water and urea), the module transforms up to 90% of
nitrogen oxides
(NOx) into inoffensive water vapour (H2O) and nitrogen
(N2);
an additive particulate filter, launched as a world
first in 2000 by
the PSA PEUGEOT CITROËN Group designed to eliminate up
to 99.9% of
particulates in number.
The innovative and unique feature of this exhaust line
lies in its
specific layout: the SCR module positioned upstream of
the additive
particulate filter is the only after-treatment system
able to reduce
NOx emissions by up to 90% as well as reducing CO2
emissions by up to
4%.
In consequence, a DS 4 equipped with the BlueHDi 120
engine and 6-speed
manual gearbox consumes 3.7l/100 km over a combined
cycle for CO2
emissions of 97g/km with 16’’ wheels (3.8l/100 km for
100g of CO2/km
with 17’’ wheels).
