Nissan ZD engine

The Nissan ZD30 engine family is a 3.0 litres (2,953 cc) with a bore and stroke of 96 mm × 102 mm (3.78 in × 4.02 in), inline four cylinder, diesel engine that replaced the Nissan QD engine. Available in both traditional turbo, variable geometry turbo (a.k.a. VGT or VNT), and non turbo versions. The engine uses a Drive-by-wire engine management system with a draw-through MAF sensor. Produced from 1999 - current, the newest models feature a common rail design.[1]

The power differences stem from types of vehicles and routing of necessary pipings, as well types of manifold with different features. Engines that produce 170 hp (127 kW) have MAF sensors incorporated in them, while the 120 hp (89 kW) and 130 hp (97 kW) versions do not use a MAF sensor. Conversions can be done using the ECU from any of the higher horsepower units using the MAF sensor along with the MAF, which has to be wired into the loom of the 120 hp (89 kW) and 130 hp (97 kW) versions.

? ALL e25 and R50 and e50 all use MAF

Version and production
  • ZD30DD is a DOHC, Direct injected, 16 valve non-turbo engine 105 hp (78 kW)
  • ZD30DDT version is a DOHC, Direct injected, 16 valve, turbocharged engine 148 hp (110 kW; 150 PS) at 3400 rpm and 32 kg⋅m (310 N⋅m; 230 lb⋅ft) at 2000 rpm, C.R. 17.9:1
  • ZD30DDTi version is a DOHC, Common rail, 16 valve, turbocharged, intercooled engine 121 hp (90 kW), 130 hp (97 kW), and 170 hp (127 kW).

There is also a ZD25 engine built in China, where it is also known as the DK4A diesel engine. With a 92 mm × 94 mm (3.6 in × 3.7 in) bore and stroke, it displaces 2,498 cc (2.5 L) and produces 75 kW (102 PS) in with common rail injection and an intercooler. Foton also builds a version of the earlier QD engine with the ZD's bore, creating an engine of the same displacement as the ZD30 but called the QD29Ti.
