Innovative,
environmentally-friendly engines
120 bhp 1.6 Multijet
The Lancia Delta is fitted with the new 1.6 Multijet, 16
valve engine, or latest generation turbo diesel engine with
Multijet, multi valve technology that confirms the
technological excellence of the Fiat group in the field of
diesel engine design and development.
The lively 1.6 l engine, available in a 120 bhp version,
complements the range of power unit produced by FPT - Fiat
Powertrain Technologies that includes 1.3, 1.9 and 2.4 litre
capacities. In particular, the new engine ideally combines
the winning attributes of Multijet turbodiesel engines with
tax breaks and other advantages deriving from the downsizing
design philosophy. This engine is therefore the ideal
solution for those who seek an effective l compromise
between respect for the environment and low running costs
without relinquishing power and flexibility for authentic
driving satisfaction.
In detail, the 1.6 Multijet improves on performance,
comfort, emissions – it is Euro 5 Ready – and running costs
compared to the tried and tested 1.9 Multijet 120 bhp unit –
it is Euro 5 Ready – while also offering considerable
benefits: For the same power output, the engine offers
nearly 25% more torque (300 Nm at 1500 rpm) and 8% less fuel
consumption (measured over a Nedc cycle). All this with
considerably improved driving satisfaction, due above all to
respectable torque values are low speeds. These aims have
been achieved through a comprehensive optimisation of
combustion that exploits the potential of the engine's new
injectors to the full.
The 1.6 Multijet offers exceptional torque delivery in
absolute terms, which is all the more impressive when one
considers the cylinder capacity: a torque of 300 Nm makes
this engine a performance leader amongst power units with
capacities less than or equal to 1.8 litres If within
consider specific torque (i.e. divided by cylinder capacity)
the 1.6 is the highest performing engine in its category up
to power outputs of 200 bhp, with the sole exception of
supersport power units. And more. If we take into account
that the maximum torque is delivered at just 1500 rpm, we
are able to immediately appreciate the extent to which the
1.6 Multijet represents a revolution compared to present-day
diesel engines: No other the engine, however recent, can
offer such a high torque delivery at such a low RPM. All
things considered, the new 1.6 Multijet offers exhilarating
driving satisfaction that is difficult to match. This
achievement is also borne out by the acceleration values
(from 0 to 100 km/h in just 10.7 seconds) and the top speed
(194 km/h).
Combining the new injection system with new-generation
variable geometry turbo engines also complete an absolutely
outstanding technological picture. In the same way, the 120
bhp 1.6 incorporates the most advanced exhaust gas treatment
technologies, namely a Close Coupled Diesel Particulate
Filter and an integral EGR (Exhaust Gas Recirculation)
system that improves control of temperature and gas flow,
simultaneously guaranteeing lower emissions and reduce fuel
consumption. This set of solutions ensures the power unit is
Euro5-ready well ahead of the date on which the regulation
enters into force: This is the best example of the great
commitments made throughout the Fiat group to ensure
environmentally-friendly mobility.
The 120 bhp 1.6 Multijet engineers combined with a six-speed
Manual gearbox that, ensures lower RPM particularly at
highway on motorway speeds, with the twofold advantage of
less noise in the passenger compartment and a reduction in
true fuel consumption.. A six-speed robotised gear box will
also shortly be available that responds to the growing need
for automatically controlled gearboxes for increased driving
comfort particularly over an urban cycle while also
guaranteeing a further improvement in fuel consumption
compared to the manual gear box.
A Lancia Delta with the new 1.6 Multijet engine or does not
need its first service until 35,000 km, with a reduction of
25% of the costs of ordinary maintenance (calculated for the
distances of 90.000 km or 100.000 km, that are most common
for long-term hire contracts ).
120 and 150 bhp 1.4 turbojet
The Lancia Delta offers its customers new 1.4 litre
turbocharged Turbo Jet petrol engines that are distinguished
by their performance, alacrity of throttle response, low
fuel consumption, simple construction, sturdiness and
reliability.
The new 1.4 16v turbo is available as two alternatives: the
first is more sporty with 110 kW (150 bhp) of maximum power
achieved at 5500 rpm while the second is more of a touring
car, developing 88 kW (120 bhp) at 5000 rpm. Both offer a
maximum torque of 206 Nm (the 110 kW at 2250 rpm and the 90
kW at 1750 rpm). Driving flexibility is therefore high, with
reduced use of the gearbox for a satisfying, relaxed drive,
though all you have to do to achieve a more beefy response
is to press you foot on the throttle. This is aided by the
low inertia of the turbocharger that makes it possible to
obtain maximum performance from a throttle command, without
the annoying lag typical of this type of engine. All this
sportiness also comes with very frugal fuel consumption.
The engine is also very reliable, guaranteed by the hundreds
of thousands of kilometres covered by the prototypes during
the development stage, combined with thousands of hours on
static and dynamic test rigs. The scheduled maintenance
interval is 30,000 km, without any need for an intermediate
service. The oil/water heat exchanger guarantees these
results The oil filter is environmentally friendly.
A computerised engine control system manages all functions
by means of sophisticated mathematical algorithms. The
throttle control is drive-by-wire without any mechanical
connection so that the driver can obtain the desired
response from the engine, i.e. smooth or sporting, always
with the greatest energy efficiency
It should also be remembered that the 1.4 Turbo Jet family
applies the downsizing philosophy: the adoption of a
new-generation turbocharger, combined with a smaller
capacity engine, allows us to achieve performance levels
that are comparable to or even better than higher-capacity
power units, but with lower fuel consumption and emissions.
And more: The presence of the turbo significantly increases
the maximum torque, making is available at a lower RPM, but
the results of offering greater flexibility and an
unrivalled response compared to conventional aspirated
engines. All this comes with an essential construction
simplicity that benefits the strength and reliability.
165 bhp 2.0 Multijet (Euro
5)
The new 2.0 165 bhp MultiJet constitutes a natural evolution
of the 1.9 Multijet from the viewpoint of performance (with
an increasing torque and power) and also of emissions
(compliance with the limits imposed by the Euro 5 directive
due to enter into force in one year). In detail, the
increase in cylinder capacity was achieved by increasing the
bore from 82 mm to 83 mm. The solution, combined with a new
variable geometry turbo, means that this engine will take up
a position at the top of the market. All this comes with
very frugal fuel consumption: over a combined cycle the car
uses just 5.3 l/100 km.
The compression ratio has also dropped from 17,5:1 to 16,5:1
(in this way it’s been possible to obtain a consistent
decrease in Nox levels) while, compared to the 1.9 Multijet,
the new power unit uses a new type of low voltage spark plug
that allows starts-ups with minimum pre-heating times.
Last but not least, compliance with Euro 5 is guaranteed by
the use of a close-coupled DPF (CCDPF) and an advanced
exhaust gas recirculation system (EGR) with all
subcomponents packed into one small element (EGR module).
190 bhp 1.9 Twin Turbo
MultiJet (Euro 5)
This new power unit, derived from the 1.9 Multijet, offers
significant new technical and performance features. The
first distinctive feature of the 1.9 Twin Turbo MultiJet is
its adoption of two turbochargers: One compact, low inertia
unit to ensure a prompt and vigorous response from lower
speeds, and one larger one to provide a very high power
output. The solution allows record-breaking performance, as
evidenced by a maximum power of 190 bhp and a maximum torque
of 400 Nm at 2000 rpm. It should be noted that the high
torque delivery (approximately 100 bhp/litre) is a value so
far reserved for out-and-out sporty petrol engines. An even
more interesting statistic is the availability of no less
than 300 Nm of torque at just 1250 rpm: this translates into
an extremely ready response to any demand from the customer
and allows a truly gratifying drive in all situations.

This
extraordinary performance comes courtesy of a twin turbine
system - hence the name Twin Turbo - that allows a powerful
turbine (designed for high speeds) to be combined with a
smaller turbine that allows an immediate by the response and
delivery of torque without annoying and detrimental turbo
lag Due to continuous control of both turbines, the 1.9 Twin
Turbo Multijet is therefore able to deliver a very high
performance and at the same time give customers the
perception that the engine is always in traction and
completely free of turbo lag
The operating strategies of both turbines are given below:
- below 1800 exhaust gases operate only the small turbine
that ensures a prompt response and sufficient power for low
rpm levels. The larger turbine turns at its minimum
operating speed and does not hinder the passage of gases
- Between 1800 and 3000 rpm, based on the operating
conditions and the drivers demands, the large turbine begins
to work, compressing the air that then passes through the
small turbine that guarantees an appropriate turbocharging
pressure and a rapid response
- Above 3000 rpm, the smaller turbine is
excluded because the larger turbine is in optimum working
conditions and is able to express all its power: In this
case the air is compressed only by this turbine and maximum
performance is achieved
200 bhp 1.8 Twin Turbo Jet
(Euro 5)
The Lancia Delta range will be completed by a powerful 200
bhp 1.8 Di Turbo Jet engine combined with an automatic
6-speed transmission. To guarantee high power, considerable
flexibility and sparkling delivery, the new power unit
introduces direct injection of petrol and turbocharging by
means of a turbo charger and twin variable valve timing on
the exhaust and intake. The combination of these different
technological solutions offers the customer considerable
advantages, for example direct injection makes it possible
to achieve lower fuel consumption in relation to the
performance delivered by the power unit. The turbocharging
also allows rapid pick-are due to a particularly favourable
torque curve. The adoption of a twin variable valve timing
system makes it possible to recirculate gases internally,
making it possible to achieve Euro 5 emission limits.
It should be emphasized that the combination with an
automatic six-speed transmission further enhances the Lancia
Delta’s qualities of flexibility and fast pick-up making the
car a very smooth drive in accordance with customers’ tastes
and making it possible to adapt to both a comfortable and a
sporty driving mode.
Slick, reliable gearboxes
It will come as no surprise to learn that a model as
innovative as the Lancia Delta also comes with
state-of-the-art gearboxes. The gearbox, after all, is
crucial in determining driving satisfaction and comfort. The
new vehicle adopts three versions (manual, robotised and
automatic), all with six-speeds.
The detailed gearbox-emption matches are shown below:
- M32: manual, 6-speed for the 120 bhp and 150 bhp 1.4 T-
Jet units
- C530: manual, 6-speed for the 1.6 Multijet 16v engine
- M32: Robotised, 6-speed for the 1.6 Multijet 16v engine
(available shortly)
The M32 and C530 gearboxes share a dual cable external
mechanism that ensures slick manoeuvres and noiselessness
without transmitting mechanical vibrations through the
linkage. The details: The new-generation external linkage is
technologically advanced due to the extensive use of
high-performance technopolymers used to guarantee the
various qualities of strength, weight and self-lubricating
capability. Bench testing under extreme weather conditions
also guided the development of materials, couplings and
processes to ensure product toughness and reliability. The
new linkage was also designed to ensure system and
performance characteristics of maximum comfort and
manoeuvrability. To achieve greater comfort through maximum
mechanical filtering action, a new distribution pattern was
adopted for a inertia mass distribution that is strongly
shifted toward the gearbox.
The quality and reliability of these components is also
guaranteed by the great care taken at the assembly stage,
when each component is pre-tested and electronic
measurements are carried out on the parameters that define
efficiency, flexibility and clearance.
M32, six-speed gearbox for
the 120 bhp and 150 bhp 1.4 T- Jet units
Increased acoustic comfort, lower shift effort even when
cold and greater gear engagement precision. These are the
benefits offered to the motorist by the M32 gearbox
(transverse configuration with two shafts in a cascade and
differential) that underwent improvements to the following
parts before fitting to the Lancia Delta: gears,
synchronisers, lubrication, inner gear linkage and clutch
control.
Available with six speeds for the 1.4 petrol family, the
device adopts a gear linkage that features a selection
travel limiter to safeguard more effectively against
involuntary engagement of reverse and increase fifth and
sixth gear engagement precision.
The gearbox offers the following noteworthy technical
features: the gear casing and clutch casing have been
optimised in terms of lightness and noise absorption though
FEM (Finite Element Method) computing techniques. The first
and second gears, i.e. those most commonly used by
motorists, come with dual cone synchronisers that require
40% lower engagement effort than a conventional single-cone
type. The internal gear control system is on four selection
planes with a central positioned and runs on bearings.
Lubrication is dynamic, with oil flows channelled through
holes in the casings. The advantages include: lower wear and
higher efficiency during torque transmission and low
temperature manoeuvrability.
M32, robotised 6-speed
gearbox for the 120 bhp 1.6 Multijet unit
A six-speed robotised gearbox – known as a ‘SELECTRONIC’
will also shortly be available that responds to the growing
need for automatically controlled gearboxes for increased
driving comfort particularly over an urban cycle while also
guaranteeing a further improvement in fuel consumption
compared to the manual gearbox.
C530 6-speed gearbox for the
120 bhp 1.6 Multijet unit
The 1.6 Multijet engineers combined with a C530 gearbox
(6-speed manual gearbox) that, ensures lower RPM
particularly at highway on motorway speeds, with the twofold
advantage of less noise in the passenger compartment and a
reduction in true fuel consumption.. In detail, the C530
gear box is remarkable for its configuration with two shafts
in a cascade formation with a differential and for its slick
silent shifting. Baulk-ring Borg-Warner type synchronisers
are also fitted to all forward speeds and reverse is also
synchronised. On the first and second speed, the
synchroniser is also triple cone. On the third, fourth,
fifth and sixth speed, the synchroniser is single cone. The
gear linkage also features a syringe to has on D passenger
compartment lever knob two inhibits involuntary engagement
of reverse and the dealing kitsch is operated by a metallic
double Bowden cable system with anti-noise devices. The
clutch control is also hydraulic to reduce operating
efforts, while lubrication is carried out dynamically, to
ensure less wear and improved torque transmission
performance and manoeuvrability even at low temperatures.
Two new gear boxes in the
coming months
To coincide with the introduction of new Lancia Delta
engines, the following gearboxes will be available after the
launch:
-F40: Manual, 6-speed for the 190 bhp 1.9 Twin Turbo
Multijet (Euro 5) and 165 bhp 2.0 Multijet (Euro 5)
- Aisin: 6-speed, sequential, automatic for the 200 bhp Di
Turbo Jet (Euro 5)
This particular gearbox offers the distinctive feature of
being a compact, light gear box that has been designed with
particular attention to reducing fuel consumption: On the
one hand, the use of low friction oil has made it possible
to increase efficiency while on the other hand the sixth
speed has been calculated to ensure it is particularly
effective for motorway driving.
Sophisticated management software makes it possible to
identify the various road conditions and adapt handling by
means of the following functions braking assist, radio
recognition, cornering, desire for a sporty drive or
comfort. Driving satisfaction has also been further
emphasized by the option of choosing ‘Winter’ ‘Norm’ and
Sport’ in automatic mode in addition to Manual mode (TIP).
