The PSA EW/DW engine is a family of straight-4 petrol and diesel engines manufactured by the PSA Group for use in their Peugeot and Citroën automobiles. The EW/DW family was introduced in 1998 as a replacement for the XU engine
All EWs are DOHC multivalve with displacement from 1749 to 2231 cc. They are mainly used for large family cars and executive cars, as well as large MPVs, although the 2.0 L is also used for some hot hatch models.
The DW started with an SOHC 2-valve design between 1968 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 and Peugeot 607. Turbocharged versions started using common 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 a variable geometry turbocharger for the first time on the 2.0 L design.

|EW7 A||125 PS (123 hp/92 kW)||16-valve catalyst|
The EW10 has a bore of 85 mm and a stroke of 88 mm, for a displacement of 1997 cc. It is used widely throughout the PSA Group, including the Citroën C4 and C5 and Peugeot 206 307 and 407. A gasoline direct injection variant, called EW10 D and marketed as HPi, was briefly used in the Citroën C5 and Peugeot 406 starting in 2001, but was discontinued in 2003 due to low sales. The EW10 J4S variant is a high performance version used in the 206 GTI 180, 206 RC, 307 Féline and C4 VTS. Power was raised to 177 PS (130 kW), although the two French brands round it up to 180 PS in advertising. EW10 A is a further development of the EW10 J4, presenting somewhat higher power and torque due to the introduction of Variable Valve Timing (VVT). Fuel consumption is also decreased. Power is 103 kW at 6000 rpm and torque 200 N·m at 4000 rpm. Citroen usually states 143 PS and Peugeot 140 PS for the same 103 kW engine.

The EW12 was introduced to replace the low-pressure turbo variant of the XU10. It has a bore of 86 mm and stroke of 96 mm, for a displacement of 2231 cc. Citroën only uses it on the C8 MPV, while Peugeot, which has more a sporty image, uses it in the 406 SRi and 406 Coupe, 407, the 607 executive model and 807 MPV.

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 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 4 emissions regulations (it is a Euro 3 engine). The DW8 is matched to the BE manual 5 speed, 250 Nm couple, manual gearbox.

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 109 PS (80 kW).
Initially available in the midsized models, such as the Citroën Xsara and Xantia and Peugeot 306, 406 and Peugeot 206 it was soon spread across the PSA range, such as the LCVs, while a 16-valve version(RHW), with 109 PS (80 kW), was used in the large MPVs built in association with Fiat. Suzuki was a customer of these powerplants, using them in the European Vitara and Grand Vitara. Eurovan-based commercial vans, the Citroën Jumpy, Peugeot Expert and Fiat Scudo were available with a 94hp DW10 BTED engine, which is essentially an intercooled version of the original 90hp design.
The DW10 was used as the basis for the new family of Diesel engines co-developed with Ford, and it is used in the Focus, C-Max and Volvo C30/S40/V50, besides various Citroën and Peugeot passenger models. The DOHC 16-valve powerplants were mated to a second generation common rail injection system and a variable geometry turbocharger, pushing power to 136 PS (134 hp/100 kW)(RHR). It is fitted with a six-speed manual transmission or six-speed automatic transmission (from summer 2006 onwards).

The 2.2 L (2179 cc) DW12 has a bore of 85 mm (3.3 in) and a stroke of 96 mm (3.8 in). Unlike the initial DW10 designs, it was fitted with 16 valves from the beginning, and made its debut in the 2000 with the Citroën C5, Peugeot 406, Peugeot 406 Coupe and Peugeot 607, being used only in the larger models. In 2006 it was added to the PSA/Ford family, with power reaching 170 PS (125 kW). Land Rover used this engine in the Freelander 2 where it produces 160PS. This is Ford's only current use for this engine, which is expected to power the next generations of both the Mondeo and Jaguar X-Type. A different 2.2L engine, Ford's ZSD-422 with a displacement of 2198 cc, will be used in the Peugeot LCV range of vans.
