The
Peugeot HDi diesel DPFS:
The choice of engine architecture has been based
on a 100° twelve-cylinder V design, This is
the maximum cylinder capacity that regulations allow
and was chosen for it efficient operation at low
speed. It also enables engine power to be limited
in the first instance, but also enables further
development.
The number of cylinders results, on the one hand,
from the wish to keep bore diameter very close to
that of a production series engine, in order to
make best use of Peugeot's diesel combustion knowledge
and, on the other hand, to limit the stroke to a
reasonable value. The V12 architecture, well known
for its good balance, also reduces vibration to
a minimum.
The 100° V angle, of the V12 architecture,
allows the height of the centre of gravity to
be lowered without affecting the torsional rigidity
of the engine.
Two diesel particulate filters are mounted at
the end of each of the exhaust systems. Through
technology which has come directly from production
cars, they will provide a guaranteed control of
exhaust emissions under all operating conditions.
The two diesel particulate filters fitted to the
engine being presented, carry the numbers 1.195.520
and 1.195.521 which are the numeric production
numbers of the filters in the overall production
total of all filters since the introduction on
to Peugeot vehicles. The level of performance
expected - more than 515kW (700 bhp) of power
and a torque output greater than 1.200 Nm - is
without precedent in a diesel engine and is a
direct result of Peugeot's current level of know-how
in diesel technology, linked to the mechanical
characteristics of the V12.
