The Nissan CD20T is a 2.0 l (1,974 cc, 120.45 cu.in) straight four, water-cooled turbocharged diesel engine from Nissan CD family. The engine was used on Nissan mid-size models from 1991 to 2002.
The CD20T has a cast-iron cylinder block and an aluminum cylinder head with SOHC (Single overhead camshaft) with two valves per cylinder. The engine was equipped with a turbocharger, electronic fuel injection pump, and EGR system.
The Nissan CD20T compression ratio is 22.2:1. Cylinder bore and piston stroke are 84.5 mm (3.33 in) and 88.0 mm (3.46 in), respectively. The CD20T produced 91 PS (67 kW; 90 HP) at 4,400 rpm of horsepower and 174 Nm (17.7 kg⋅m, 128 lb⋅ft) at 2,400 rpm of torque.
The breakdown of the engine code is as follows:
- CD – Engine Family
- 20 – 2.0 Liter Displacement
- T – Turbocharger
