Extremely high injection pressures are necessary in
order to reduce PARTICULAR emissions.
The common rail system makes it possible to inject
fuel at pressures of up to 1450 - 1600 bar (21030 -
23206 psi), while the injection precision obtained by
EDC7UC31 electronic control of the system serves
to optimize operation of the engine while limiting
emissions and fuel consumption.
For engines more powerful than 152 kW (203 hp.),
the CRIN2 injectors have DLLA nozzles that work up
to a pressure of 1600 bar (23206 psi), while engines
less powerful than 152 kW (203 hp.) are fitted with
DSLA nozzles which work with pressures up to 1450
bar (21030 psi.)
