The Duratorq DLD-414 (or DV4) is a 1.4 L (1398 cc) straight-4 turbo-diesel. Output is 68 PS (50 kW; 67 hp) at 4500 rpm and 160 N⋅m (118 lb⋅ft) at 2000 rpm.

The DV4 is available in two versions:

One, a SOHC 8-valve design, uses a KKK KP35 turbocharger but no intercooler. This is the same turbocharger as the Renault K9K Diesel. It is Euro 3 compliant, but will receive a Diesel particulate filter from 2006 to make it Euro 4 compliant. In Ford, Mazda, and most PSA applications it uses a Siemens SID804 or SID802 common rail injection system. The PSA Variant in the 2005-2008 Citroën C1/Peugeot 107/Toyota Aygo 1.4 HDi uses the Siemens SID805 common rail injection system with a lower power output compared to other applications to compensate for the weaker 5-speed manual transmission used in these models. [3] In some PSA applications a Bosch common rail system is used.[citation needed]
A second version uses a DOHC 16-valve design, with an intercooled variable-geometry turbocharger. This engine uses Delphi Corp.'s DCR1400 common-rail injection system. This derivation will no longer be built from 2006, as it will not be able to comply with the EURO4 regulations.
