Hello, while surfing the net I came
across this press release on the new "PRV" engine. Quite a few years have
passed since the DeLorean's birth, and one of the change with the PRV
(Peugeot-Renault-Volvo) consortium in Douvrin, France, was that Volvo pulled
out. Volvo is now owned by Ford.
The PRV changed name to PSA, andconsists
now of only the French automakers Peugeot-Citroen-Renault.
Some of you may remember I mentioned the
new PRV-V6 on the list a few months back...one of the European cars that have it
installed is the Renault Clio (rally version). I wonder if the new
engine would fit in the DeLorean - I believe it would. If you would like to
see a photo of it, go to the DMC News vault and find it in the folder New PRV.
The engine now produces 210 horsepowers! More info on http://www.psa.fr/ The only thing difficult
now is to think of it as a PSA instead of a PRV ;-)
Best wishes Stian

PSA PEUGEOT CITROËN and Renaultto
Introduce New V6 Engine |
Beginning in early 2000, a new 3-liter (2,946 cc)V6
engine, developed by a cooperative venture between PSA PEUGEOT CITROËN and
Renault, will be gradually introduced on both carmakers’ mid-range,
upper-range, and MPV model lines. The first vehicles to be equipped will
be the future Peugeot upper-range model scheduled for presentation atthe
Frankfurt Auto Show in September, and the Renault coupe developed from the
Avantime concept car. The new engine, which is an improved version ofthe
ES9 model introduced in 1996, was developed at a relatively low cost of
FRF 464 million, of which FRF 80 million in capital expenditure. It will
improve performance and lower fuel consumption, while complying with new
Euro3/2000 emissions standards. A Euro 4/2005 version will be available in
the near future. The engine will be produced at a rate of 300 units aday
at the La Française de Mécanique plant in Douvrin,
France.
Specifications for the new PSA PEUGEOT CITROËN/Renault
3-liter V6 engine call for: - Lower fuel consumption. - Better
performance (power and torque). - Compliance with new European
emissions standards to become effective in 2000 and 2005. - Possibility
of two-way dialogue with an automatic transmission to adjust torque to
gear changes. - Easier maintenance, with oil changes every 30,000 kms,
low viscosity oil and sparkplug changes after 120,000
kms. Performance, consumption and handling The new engine’s
power has been increased by 8% to 152 kw (210 hp), versus 140 kw (194hp)
for the engine it is replacing. Maximum torque is 285 N.m at 3,750 rpm,
versus 267 N.m for the earlier version. Low speed torque has been
thoroughly reworked and increased by 10% to 260 N.m at 2,000 rpm,
providing a more pleasurable driving experience.
Fuel consumption
has also been substantially improved. While mileage will vary, depending
on the marque or vehicle type, overall consumption has been lowered by one
liter per 100 kms, in combined European city and highway tests (ECE and
EUDC standards).
Superior environmental
performance Improving the engine’s technical features has also
significantly enhanced its environmental performance. The new PSA PEUGEOT
CITROËN/Renault V6 engine complies fully with Euro3 standards (to be
applied as of January 2000 for new models) and will rapidly be upgraded to
meet Euro4 standards (for which tax incentives will be offered in advance
of the January 2005 application date).
Adjustments to the new
standard will involve the engine management system, the precious metal
content of the catalytic converter, and development of the European
On-board Diagnosis (EOBD) system. These improvements will be integrated
gradually, depending on the two partners’ new vehicle introduction
schedules.
Major technical changes The engine has been
entirely redesigned, with a thoroughly reworked upper section. Changes
include: - A newly designed combustion chamber and intake manifold
built in partnership with Porsche, for the combustion management system,
and with Bosch, for the engine management control and injection
systems. - Engine acoustics (NVH) were handled in association with
Ricardo. - A new six-pipe intake manifold, increased to 12 pipes where
it feeds into the combustion chamber, with each nozzle positioned on two
pipes. - Multi-hole and sequential injection nozzles. - Motorized
throttle housing. - Single coil ignition system (one per
cylinder). - Variable timing camshaft.
In the lower engine
section, the crankshaft, made of meshed forged steel and machined with
variable burnishing, is produced in France at the Courcelles
foundry.
Investment and production Development of the new
V6 engine involved one-time expenses (for design, engineering and process
development) of FRF 464 million, of which FRF 80 million was investedin
manufacturing facilities. The original engine, introduced in 1996, had
cost FRF 2.5 billion, including FRF 1.3 billion in capital
expenditure.
The engine will be produced at the Douvrin, France
plant operated by La Française de Mécanique, a joint PSA PEUGEOT
CITROËN/Renault venture. Full-year output is forecast at 300 units a day,
versus the 120 units a day currently produced. This 250% increase in
volume is in line with expansion in both Groups’ model line-upsand the
large number of vehicles to be equipped with the new V6
engine.
