DW10
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 and a stroke of 85x88 mm for a total displacement of 1997 cc, replacing the XUD9 in 1999. It was initially available in 90 PS form, with two valves per cylinder and a non-intercooled turbo. An intercooler was added later in the year, boosting power to 109 PS.
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, was used in the large MPVs built in association with Fiat. Suzuki was a customer for these powerplants, using them in the European Vitara, Grand Vitara, and XL-7. Eurovan-based commercial vans, the Citroën Jumpy, Peugeot Expert and Fiat Scudo were available with a 94 PS DW10 BTED engine, which is essentially an intercooled version of the original 90 PS design.
The DW10 was used as the basis for the new family of Duratorq Diesel engines co-developed with Ford and Volvo it is used in the Focus, Kuga, Mondeo Mk4, Mondeo Mk5, C-Max and C30/S40/V50/C70, 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 (RHR). It is fitted with a six-speed manual transmission or six-speed Aisin-automatic transmission (in Citroën C5 from summer 2004 onwards).
The DW10BTED4E5 and DW10C are Euro 5-compliant, and therefore still available for sale in Europe.[2]
2014 Euro 6 variant DW10FC and DW10FD introduced selective catalytic reduction emissions control technology.
This engine is known as the 4WZ when installed in Toyota vehicles such as Toyotas version of the Citroën Jumpy.
