YD22


YD22DD

Winner of the FY 1998 ''Sho-Ene Taisho'' (The Energy Conservation Prize), this engine was marketed as the NEO Di. The YD22DD is used in the Y11 Nissan AD Van and the Nissan Expert (VEW11).Nissan-Global

It is a naturally aspirated 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 four injector bumps on the top of the acoustic cover. Non intercooled versions of this engine were also available with a lower power rating.


YD25


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 (

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. Nissan also produced a version tuned for less power, better economy, and cleaner emissions. Intended specifically for commercial vehicles it was introduced in 2012 for the NV350 Caravan and replaced the earlier, 3-litre ZD30DDTi engine. Still using a revised variable geometry turbocharger, it also features an EGR cooler to lower NOX, with a bypass valve to avoid increasing hydrocarbon emissions before the engine reaches operating temperature, and a cylinder head optimized per Nissan's MK (Modulated Kinetics) combustion method. ;Applications * 1998–2001

YD25DDTi High Power ("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 geometry turbocharger (Garrett GT2056V). 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. 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 D40 Navara and facelifted R51 Pathfinder to produce and of torque.Nissan facelifts the Navara and Pathfinder
