The EW/DW family was introduced in1998 as a replacement for the XU engine.The EW/DW uses many parts from the XU, most notably the
crankshaft , but is built with lighter materials. The EW name is used for the petrol engines ("e" for "essence") and DW for Diesel engines.All EWs are
DOHC multivalve with displacement from 1749 to 2231 cc. They are mainly used forlarge family car s andexecutive car s, as well aslarge MPV s, although the 2.0 L is also used for somehot hatch models.The DW started with an SOHC 2-valve design between 1868 and 1997 cc, later receiving DOHC and four valves per cylinder upon the introduction of the 2.2 L in 2000 with the
Citroën C5 andPeugeot 607 . Turbocharged versions started usingcommon rail and received the commercial designation HDi. The DW10 served as the basis for the Ford/PSA engine partnership using second generation common rail and avariable geometry turbocharger for the first time on the 2.0 L design.EW7
The EW7 has a
bore of 82.7 mm and astroke of 81.4 mm, for a displacement of 1749 cc. It is used as an entry level engine for theCitroën C5 , thePeugeot 406 and thePeugeot 407 .DW8
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
van s such as theCitroën Berlingo andPeugeot Partner but can also be found in more affordable versions of the Peugeot 206. The DW8 was phased out in 2007 as it does not passEuro IV emissions regulations.ee also
