The PSA EW/DW engine is a family of four cylinder petrol and Diesel engines manufactured by the PSA Group for use in thier Peugeot and Citro�n automobiles. The EW/DW family was introduced in 1998 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 for midsize and executive models, as well as large MPVs, although the 2.0 L is also used for the sports version of compact 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 Citro�n C5 and Peugeot 607. Turbocharged versions started using common-rail direct injection and received the commercial designation HDi. The DW10 served as the basis for the Ford/PSA engine partnership using second generation common-rail and a variable geometry turbocharger for the first time on the 2.0 L design.

Variable geometry turbocharger improves upon turbocharger design by automatically changing the size of the vanes in the turbine housing, allowing control of boost by controlling exhaust turbine inlet pressure. The size of vanes changes positively as engine speed increases. At low engine speeds, the increased pressure generates higher boost than traditional turbine design.

Holset variable geometry turbocharger changes exhaust air pressure by using piston to push vanes parallel to the rotational axis, instead of pivoting the vanes.
