> V6 engine with "maintenance-free" filter for Peugeot HDi 607
>
> The French PSA Group introduced for the first time a six cylinder
> diesel engine to its Peugeot HDi 607 automobile. The 2.7 liter V6
> engine has been developed under the cooperative program between PSA
> Peugeot CitroÎn and Ford in the Jaguar development center in Whitley,
> UK. The same engine was earlier introduced in the Jaguar S-Type model
> (see DieselNet Update - June 2003).
>
> The V6, Euro 4 engine has a capacity of 2,720 cm3 and produces 150 kW
> at 4,000 rpm. The maximum torque of 440 Nm is produced at 1,900 rpm.
> According to PSA and Ford, it is the industry-first engine using
> compacted graphite iron (CGI) technology instead of the conventional
> cast iron block.
>
> The engine features a piezoelectric common rail injection system
> operating at pressures up to 1,650 bar. Six injection events are
> possible: two pre-injections to control noise, two main injections,
> and two post-injections for the regeneration of the diesel particulate
> filter. The engine is equipped with two variable geometry
> turbochargers. The engine's electronic control module receives input
> from 23 sensors and sends instructions to 20 actuators to manage the
> engine operation.
>
> The engine is equipped with the newest "maintenance-free" version of
> the Peugeot diesel particulate filter, which can be operated without
> maintenance for a period of 200,000 km. The filter utilizes the Ibiden
> "octosquare" substrates, where the octagonal inlet channels are larger
> than the outlet channels, to provide increased ash storage capacity.
> The filter utilizes the Eolys cerium/iron additive by Rhodia for
> regeneration.
>
> Peugeot 607--launched in May 2000, with a 2.2 liter 4-cylinder engine-
> -was the fist modern diesel car to be equipped with a particulate
> filter. Since that time, about 900,000 filter systems have been sold
> in various models of Peugeot diesel engines. The first version of the
> system required maintenance (washing from ash) every 80,000 km.
