Hi. This bit of random chatter resulted from an inaccurate listing I found while searching for a van for one of my clients. I thought the general content might be useful to someone, and it saved me thinking of something else to create to fill my profile instead. :D
"The photos on the listing clearly show the air intake tubing running directly from the air filter housing to the inlet manifold. The turbo on any engine of this 'pattern' is fitted at the rear of the engine, so the tubing would be routed there and back again, often via a front mounted intercooler next to the main radiator. I believe the 1769/1905cc XUD engine was last used in the 1998 model, and the 1868cc DW8 was released in car-derived vans in 1999, the same year that the Peugeot 206 launched using the DW8. The XUD engine doesn't have any sort of plastic cover, the DW8 has a half plastic cover that matches up to the inlet manifold curves, and the post-2000 1997cc 2.0 DW10 HDi has a complete plastic cover. The 1398cc 1.4 and 1560cc 1.6 HDi models that were released around 2004 have a similar plastic cover, but have a totally different engine design with the turbo mounted at the front."

The DW8 is for all intents and purposes an evolution of the XUD9 and is the only Diesel engine in the family not to feature a turbocharger or common-rail direct injection. It has a bore of 82.2 mm and a stroke of 88 mm for a displacement of 1868 cc. It is mainly used in vans such as the Citroën Berlingo and Peugeot Partner but can also be found in more affordable versions of the Peugeot 206 and 306. The DW8 was phased out in 2007 as it does not pass Euro IV emissions regulations (it is an Euro III engine).
The 2.0 L DW10 was the first PSA Diesel engine to feature common rail direct injection, and was given the commercial designation HDi. It has a bore of 85 mm (3.3 in) and a stroke of 88 mm (3.5 in) for a total displacement of 1997 cc, replacing the XUD9 in 1999. It was initially available in 90 PS (66 kW) form, with two valves per cylinder and a non-intercooled turbo. An intercooler was added later in the year, boosting power to 107 PS (79 kW).
