Nissan YD engine

The YD engine is a Inline-4 diesel engine from Nissan. It has a cast-iron block and aluminium head with chain driven DOHC. The engine shares much of its architecture with the QR petrol engine.

YD22DD

Winner of the FY 1998 Sho-Ene Taisho (The Energy Conservation Prize).
The YD22DD is used in the Y11 Nissan AD van& W11 Expert.Nissan-Global
(Model Lineup 2002)
(Nissan Expert 1999)
(Nissan AD 1999)
It is a non turbo engine utilising the VP44 electronic controlled rotary injection pump.

YD22DDT (VP44 pump)

The YD22DDT is used in the X-Trail, N16 Almera. It features the VP44 electronic rotary injection system and wastegated turbochargers. The VP44 pump models are easily spotted due to a flat acoustic cover over the engine.

YD22DDTi (common rail)

The YD22DDTi was a common rail diesel introduced in 2001, during the first small facelift of the P12 Primera, N16 Almera and V10 Almera Tino. It is also fitted to the Nissan X-trail. The injection system is common rail with a variable vane turbocharger is intercooled and produces the most power and torque of all the YD22 engines. Cars with this common rail engine usually carry the DDTI badge. The common rail version is easily distinguished from the VP44 model by the 4 injector bumps on the top of the acoustic cover.

Non intercooled versions of this engine were also available with a lower power rating.

YD25DDTi (VP44 Pump)

This engine features the VP44 rotary injection pump and is turbocharged and intercooled. In the Presage/Bassara it is fitted sideways with a variable vane turbocharger ( Garrett GT1749V) and torque is limited to approximately accommodate the 4 speed automatic gearbox attached.

In the D22 Navara/Kingcab/Frontier the engine is essentially the same other than modifications to accessories, mounts and plumbing to accommodate the longitudinal engine layout. The turbo is a wastegated IHI RHF4 which is also intercooled. The stronger gearbox allows it to produce more torque than the Presage/Bassara version.

Applications

* 1998–2001 Nissan Presage
* Nissan D22 pickup (Navara / Kingcab / Frontier)
* Nissan D40 pickup (Navara) ()
* 2004–present Nissan Frontier

YD25DDTi High Power (common rail a.k.a. DCi)

The model description YD25DDTi technically refers to the YD25 engines which use the VP44 rotary electronic injection pump and run injection lines to each cylinder. It is equipped with a variable nozzle turbocharger (Garrett gt2056v).
This DDTi engine was last used in the Presage/Bassara and the D22 Navara.

The common rail versions of this engine are referred to in Europe as DCi. The common rail engines are used in the D40 navara, late model D22 Navara and the R51 Pathfinder. This is the engine referred to below.

YD25DDTi High Power was developed in 2005 for the Nissan Navara (D40) and the Nissan Pathfinder (R51). It initially produced at 4,000 rpm and of torque. In 2010, Nissan updated the engine and the turbo(BV45 from gt2056v) for the Nissan Navara (D40) and Nissan Pathfinder (R51) facelift to produce and of torque.Nissan facelifts the Navara and Pathfinder
/ref> In 2011 the Nissan Murano was fitted with the updated engine.

Applications

* 2006–2014 Nissan Navara (D40)
* 2005–2012 Nissan Pathfinder (R51)
* 2011–2014 Nissan Murano
* 2013–present Nissan NV350 Caravan/Urvan E26
